Layne Bowler’s history can be traced back to 1882, when the inventor, Mr. Mahlon Layne drilled his first well and found himself in need of a different pump to get the water out from his drilled well. Few years later, Mr. M. Layne and the entrepreneur Mr. P.D. Bowler joined in a manufacturing venture called Layne / Bowler, which had spread from the Mississippi basin to all over the world. In 1965, Layne Bowler Pump Company Inc. was established and it was the first pump factory in Turkey as well as in the area “The Middle East and East Mediterranean countries”. Today, Layne Bowler is producing almost all kind of pumps, including the split case type.

2. DOUBLE SUCTION SPLIT CASE PUMP

2.1. General

Split type (SP) pumps are radial flow pumps which have horizontal shaft, in general, splitable upper and lower casings, double suction, single or multi stage, with or without diffuser. For special applications SP pumps can be produced with vertical shaft and for high pressure.

Utilization area of split type pumps are:

• Potable water supply systems• Irrigation• Industrial water supply to factories, complexes• Sea water pumping• Closed cycles for water cleaning, water cooling, filtering, condensate pumping etc.• For pumping crude oil, petroleum products and other chemicals in chemical and petrochemical industries.

Advantages are:

• Safe working in all conditions, high head and high pressure at discharge as well as suction. • Easy and economical maintenance and repair,• Motor can be coupled to the pump from both sides,• Perfect design and modelling of casing & impeller; smooth running and low radial load are securing a high efficiency and long running life, • Vertical and horizontal applicability.

2.2. Construction

2.2.1. Casing

From the shaft level, the pump is splitable into 2 parts, the upper and lower casing. In the lower casing, the suction and discharge flanges are in opposite position and on the same axis (however different flange positions are also possible). Upper casing acts as a cover to reach inner sides of the pump and to remove rotating parts easily.

It is easy to maintain and repair the pump, only by opening the upper casing without dismantling from pipe line and chassis.

Pump rotor is lifted without using any special tool. Due to the use of elastic coupling, the rotor can be removed without moving the motor.

Wear rings protect the casing. They are fixed to lower casing to avoid their rotation with the impeller.

In case of head Hm>100 mWC, the pump casing is produced with double volute to decrease the radial load.

2 .2.2. Impeller

Impellers are produced with double entry, radial flow and double awry blades. Impellers are fixed by means of impeller lock nuts on the shaft and shaft sleeves (some models have extended sleeves). Different impeller models can be used in the same pump to widen the working range of the pump and to adapt variable working conditions. Only by changing impeller, same pump can be run in different working points.

Double suction impellers balance the hydraulic axial load just like the impellers which run in back to back arrangement.

6

2.2.3. Bearings

In general, greased type ball bearings are used when specially requested or required for some applications, journal bearings can be used. Bearing houses, which are rigidly fixed to lower body, can be removed together with the rotor, when unbolted. Bearings are protected from the pumped water by the seal and deflector.

Journal bearings can be lubricated with grease or thin clean water film (grease for bronze-stainless steel application, water lubrication for EPDM-stainless steel application).

2.2.4. Sealing

For the water leakage between pump shaft and its casing, graphite or teflon soft sealings are used. This considered as standard production, optionally or as per customer request, mechanical seals can be applied.

2.2.4.1. Soft sealing

Sealing rings and lantern rings are used in stuffing box assembly. Shaft sleeves are protecting the shaft from possible wear out in stuffing box area. Lantern ring feeds the sealing with pressurized water which is coming from the pump. In case of dirt or particle in the pumped water, the cyclone separator is securing the cleanness of the water. The water flow can be controlled with a valve.

2.2.4.2. Mechanical sealing

According to special requests or in some special applications, split case pumps can be produced with mechanical seals. Type of the mechanical seal is selected according to application type. For more information, please get in contact with Layne Bowler.

3. INSTALLATION

3.1. Site

Pumping unit should be placed as close as possible to its pedestal. Floor space must be sufficient for installation works, inspection and maintenance. Be sure to allow for crane or hoist service.

3.2. Foundation

Foundation should be constructed according to the drawing of “Foundation Details”. If requested, static and dynamic load diagrams are supplied to customer for designing the foundation details by their own technical services according to specific standards or conditions. Foundation block must be isolated from the building according to the drawing of “Foundation Details” to prevent the affects of vibration.

Anchor bolts must be positioned and levelled according to the drawings and before grouting they must be checked properly.

3.3. Preparation for installation

Pumping units are shipped fully assembled, in some cases driving units may be assembled at jobsite. Clean the working area and remove packing of the pumping unit. Check all bolts and nuts on entire unit to make ensure secure tightening. Check all necessary bolts and nuts for foundation, chassis and couplings.

3.4. Handling techniques

Utmost care should be shown in moving the pump. Pump should be lifted by sling, steel rope and chain from the marked area on lower casing (in case of using steel rope or chain, a protecting sheet should be used between pump body and rope or chain). Eyebolts on the upper casing are used to lift upper casing only for inspection and maintenance. Do not use eyebolts to lift the entire casing. General safety rules and procedures should be strictly followed while lifting.

3.6. Coupling pump and motor

Place the motor on chassis in accordance with the installation drawings. Do the levelling and alignment of the

motor shaft axis according to pump shaft axis. For a proper alignment and levelling use the techniques given

in section 3.9. After this control, tighten the bolts for motor-chassis mounting.

3.7. Preparation of stuffing box

Pumping units are shipped together with packed stuffing boxes. In case of long storage periods, soft packing

should be renewed before first commissioning. The pumps which are dispatched from factory without

connecting the sealing or sealing cooling system (in some cases, stuffing boxes can be sent as disassembled

to avoid unwanted damages during shipment), has to be assembled or fixed at its final destination or site and

controlled before start up.

When the pumps are furnished with mechanical seals, the seals are installed and adjusted at factory before

shipment. To protect the mechanical seal during transportation, extra fixtures are used to prevent the axial

movement of the shaft; these fixtures must be removed during installation at site. To prepare the seal for

operation, flush lines (if any) dispatched separately from main body, must be connected in accordance with

the manufacturer's specifications. Installation drawings are attached to the pump and should be filed for

future use to adjust the seal when the pump is disassembled. Please keep the drawing and the user manual

of the mechanical seal to do maintenance accordingly.

3.8. Checking the sense of rotation

Before tightening the flexible coupling connection bolts, the motor sense of rotation should be checked. A

rotation arrow is located on the pump upper casing. Serious damage can happen if the pump runs in wrong

sense or direction. After all the electrical connections of the motor are done and before coupling it to the

pump, it is always advised to run the pump for a very short time to be sure about its sense of rotation. After that

control, the flexible coupling connection can be done.

Attention! Make sure that you never run the pump without liquid i.e. dry.

3.9. Alignment of flexible coupling

In general, couplings are dispatched as assembled on the pump motor set. The installation and adjustment instructions must be strictly followed for coupling adjustment before commissioning. Misalignment of the couplings may cause vibration, noise, damage in the bearings, housings and couplings.

Three popular methods can be applied to check the alignment of the couplings:

• Ruler-Line gauge method (most used method, technicians can apply the description which is given below easily)• Dial gauge method (it needs a rigid system and its calculation method is not easy, but when applied correctly, this method is more accurate in comparison with the ruler method)• Computer aided laser measurement method (this is the most available accurate method; with the aid of computer adjustment it can be done easily and without mistakes)

The coupling halves are normally produced to meet H7/k6 standards. Before starting the coupling connection, it should be checked that the pump was levelled properly and its fixation bolts to chassis was tightened. Then it should be controlled that motor fixation bolts are loose. During coupling adjustment motor is moved slightly to its correct position.

Pump and driver shafts have to be well levelled and aligned as good as possible. If painting is noticed on the machined surfaces, it should be cleaned or removed immediately by means of a dissolvent before starting alignment (do not wipe or grind with any hand tool). To facilitate the parallel alignment, the couplings are of the same size. To check this concentric alignment, use a ruler at different points of coupling periphery and remain always parallel to the shaft.

There should be a gap between coupling halves for flexibility. This gap should be around 3 to 5 mm, but not more. Axial adjustment is made by sliding the motor on the chassis.

The angular alignment should be checked by inserting a feeler gauge into the space between the two coupling halves, at different points of the periphery. If the gap is the same at opposite points, this means that there is no angular misalignment.

After final fixation of motor bolts, alignment has to be checked once more and then bearings rubbers or cushions are inserted then the special coupling bolts and nuts are firmly tightened. Before this, sense of rotation should be checked as per section 3.8.

Before running the pump set, be sure that the coupling guard is installed.

3.10. Connection of pipe

Connect the suction and the discharge pipes; it is recommended to use the minimum possible number of fittings. A dismantling piece and a valve must be used at the pump discharge for flow control. If there is positive pressure at the suction side, another valve and dismantling piece must be used there to facilitate the maintenance of the pump.

For priming the pump units, a vacuum pump is used. This vacuum pump can be connected by means of pipe network to serve all of the pumping station. Vacuum system can be designed for manual and automatic operation, and it is operated just before the start-up of pumping unit or station to fill the pumps with water or liquid to a certain level.

To maintain good suction and discharge flow conditions, pipe levelling should be done properly and suitable reductions and bends should be used. This will eliminate air gaps, cavitations and other possible problems, so, piping design drawings and all technical recommendations should be strictly followed.

Layne Bowler Pump Company Inc.

• All centrifugal pumps should be started up with closed discharge valve.

• Before stopping the pump, first close the valve on the discharge line, then stop the pump.

• In case of positive suction head, make sure that the suction valve is completely open.

• In case of negative suction head, make sure that no air gaps in the pump body.

• Make sure that water is coming from stuffing when the pump is running. Adjust the quantity of water as

you wish by using the valve on stuffing cooling pipe.0• Stop the pump in case the temperature of pump bearings increases over 80 C.

• Follow up the current and power values of the motor from the control panel. If the readings are

exceeding motor label values, please stop the pump.

• In case of availability of stand-by pumps in a station, run each of them in sequences of 8 hours.

• Do not run the pump more than 2 minutes with closed valve.

• Check the manometer at the discharge of pump to see whether the pump is running at its working point

or not.

• For negative suction pumps, make sure that water level value of suction tank does not drop below its

calculated minimum value.

• For positive suction pumps, by mean of manometer, make sure that pressure value in suction pipe does

not to drop below calculated minimum pressure value.

• In case of pump noise and vibration, please stop the pump. Check the flexible coupling and

the connections of the pump on its chassis. Re-align the flexible coupling if needed.

• If you want to decrease the pump capacity of the temporarily, throttle or reduce the discharge valve.

• It is never allowed to adjust the discharge rate from the suction valve.

• In order not to damage the electrical motor, make sure that the voltage stays in the range of ±5% of the

nominal voltage.

• To determine the sense of rotation of the pump, do not start up the electrical motor before vacuuming.

• Do not run the pump dry even for determination of the sense of rotation.

• After running the pump for 4000 hours, change the oil of the bearings completely. Wash the bearings

with solvent, fill them with grease and reinstall. After that fill the new oil into pump bearing house.

Overfilling of oil causes overheating on the bearings. The recommended oil is “Shell Alvania R3” or its

equivalent.

• Change the gland packing of the pump when the packing boxed cover is squeezed up to the thickness

of one unwrapped ring of packing. Joints of every twist should be misaligned. Recommended standard

soft sealing material is “Teflon”.

• Make sure that the water outlets of sealing are not clogged. Otherwise water will go the bearings. Stop

the pump if the evacuation pipe is blocked. Do not re-run the pump before cleaning it.

• For inoperative pumps, especially during winter time, avoid freezing of the water in the pump. For that,

drain the water out from the pump by opening the plugs under the suction and discharge. This emptying

operation should be done with closed suction and discharge valves.

• To open the upper casing of the pump, first, turn off the suction and the discharge valves. Then open the

plugs under the suction and the discharge ends. When water stop to come from these plugs, this means

that there is no leakage from the suction or the discharge valves and the upper casing of the pump can be

opened.

• For new pump installation, strengthen the chassis by filling concrete into it and follow all the notes given

in the technical drawing for the basement.

• If vibration value of pump-motor bearing is read-out over 4 mm/sec for horizontal pump and 7 mm/sec

for vertical pump, please stop the pump set immediately and do the necessary controls to find out the

reason of high vibration. Usually, such a vibration is due to misalignment on the pump flexible coupling

or because of un-tightened bolts on chassis.

• The pump should be running according to the values written on its name plate. Otherwise, please get in

touch with factory.

4. POINTS TO CONSIDER DURING AND AFTER START-UP AND OPERATION

21

5. MAINTENANCE AND REPAIR

To remove the upper casing of the pump for inspection or maintenance the below items should be followed:

• Disconnect the drive from power supply and take all precautions to avoid unwanted run of the pump during dismantling operation.• Close all the valves.• Remove the coupling screws.• If needed, disassemble the sealing water feeding pipes, bearing lubricator pipes, manometer etc. • Remove the gland packing.• Remove the bolts holding the upper casing.• Locate and tight the eyebolts for hoisting or lifting the upper casing.• Remove the upper casing by lifting from the eyebolts.

For the disassembly of the rotating elements proceed as follows:

• Remove the bolts holding the bearing housing and the housing body together.• Remove the complete rotor by lifting with sling.• Do not lay the shaft-impeller-bearings assembly down on the floor which may cause damage.

6. OPERATIONAL PROBLEMS AND SOLUTIONS FOR PUMPS

6.1. Insufficient discharge

• The gap between the impeller and sealing ring might be over the acceptable limits. For that reason change the sealing ring.• Manometric head value might be over the value written on the pump name plate. If the motor power is enough, use another impeller with bigger diameter.• Impurities or unwanted particle might enter the pump. Open the upper casing and clean inside the pump as well as the impeller.• Air might accumulate in the pump. In such case, first stop the pump, then evacuate the air and re-run the pump• If there is strainer or foot valve in suction side and there is a flow problem, please make sure that no dirt is accumulated and clog them.• The valve in pump suction side might be closed or semi-closed. Make sure that the valve is open.• Suction head value might be over the allowable suction head value. For that reason, wait until getting the designed or appropriate water level.• Impeller might be broken and need to be changed.

6.2. No discharge

The valve in pump suction side might be closed. Make sure that the valve is open.• • Air might accumulate in the pump. In such case, first stop the pump, then evacuate the air and re-run the pump.• Manometric head value at closed valve is higher than the value given during the pump factory test. This will lead to air chambers inside the pump. To solve this problem, please empty the water in the discharge line until the closed valve value go down below the known test value. • Alter the motor electrical connections, if the pump is operating in reverse direction.• If there is strainer or foot valve in suction side and there is a flow problem, please make sure that no dirt is accumulated and clog them. • Site suction head dropped below the allowable or design suction head value. In this case, please wait until the suction head increase to it requested value.• Check if the used pipes at the pump discharge are obeying the hydraulic rules or not. Pipe diameter and pressure class should be according or suitable to the pump. • Impeller might be broken and need to be changed.

6.3. Pump efficiency under its label value

• If the pump is not giving the requested or designed pressure head, please adjust the valve at the discharge by opening or closing it until getting the necessary head value. If it is not possible to get the designed value, you must get in touch with the factory to check or learn the impeller diameter. • Mechanical problem might occur in the pump. So first stop the pump and inspect. Problem can be due to impeller, sealing rings or due unwanted particles in the pump or impeller. It can also depend on a broken bearing or misalignment of flexible coupling, etc... • In case of cavitation, stop the pump and search for the reason behind. This can be due to a suction heap drop below the allowable or design suction value, because of air entered the pump from the suction equipment, some dirt or particles stuck in the strainer or foot valve at suction side or a change in the pumped liquid temperature. • The space or gap between the impeller and the sealing ring might be over its required value; this will lead to losses in capacity and decrease in efficiency. In such a case, please change the sealing ring.• Low efficiency can be due to the measurement tools; to avoid that all measurement devices should be calibrated.• Impeller might be broken and need to be changed.

6.4. Excessive power consumption

• Manometric head value might be under the value written on the pump name plate. Please note that for centrifugal and semi-centrifugal impellers; pumps absorb more power when the head value is lower than its designed one; however it is the opposite case for mixed flow and propeller impellers.• It can be due to cavitation; therefore stop the pump and follow the previous notes to find the reason.• Mechanical problem might occur in the pump. So first stop the pump and inspect. Problem can be due to impeller, sealing rings or due unwanted particles in the pump or impeller. It can also depend on a broken bearing or misalignment of flexible coupling, etc. • Density of the pumped liquid might be high. Check the density of liquid as well as its viscosity.• Sealing of pump might be over tightened. Please stop the pump and check.• Sealing might not getting enough water. Stop the pump and find the way to get the necessary water. • There might be problem in the motor connection to power supply; please check.
