RECLAMATION PUMMPS

VERTICAL TURBINE WATER PUMPING UNITS

PART 1 -- GENERAL

1.1 DESCRIPTION

A. Design, furnish, factory test, and deliver vertical turbine recycled water pumps with inverter duty motors complete, including appurtenances, as indicated and specified. New motors and pumps will replace existing motors and pumps at two irrigation pump station facilities owned and operated by the City of Santa Rosa. The three vertical turbine pumps shall be custom fabricated to match the existing bases or sole plates, and the pump discharge heads’ centerlines shall match the centerlines of the existing discharge piping at each location.

1.2 RELATED WORK

A. Others will design, furnish and install electrical enclosures, equipment, controls, variable speed motor drives, conduit and conductors under a separate contract.

B. Others will furnish and install the fittings, gate valves, air release valves, thrust restraint, pipe and appurtenances for mechanical connections to the existing pump discharge piping under a separate contract.

1.3 SYSTEM

A. A total of three (3) new inverter duty motors and pumping units will be installed at two existing pump station complexes in the City of Santa Rosa’s reclaimed wastewater irrigation pumping system to improve energy efficiency. The Meadowlane pumping complex, adjacent to the Llano Road treatment facility, pumps recycled wastewater for irrigation use into its distribution system. The Rohnert Park pump station is an irrigation booster station that serves landscape and agricultural users in the vicinity of Rohnert Park. 1. The Meadowlane pumping complex was constructed in the mid 1970s. All pump motors at

the Meadowlane facility are currently fixed speed. An existing 150 HP fixed speed vertical turbine pumping unit will be replaced with a 200 HP inverter duty motor and vertical turbine pump at E Station (Pump EB2), and an existing 150 HP fixed speed pumping unit will be replaced with a 30HP inverter duty motor and vertical turbine pump at Pond B (Pump B1P).

2. The Rohnert Park pump station was constructed in 1994 and uses a combination of variable speed and fixed speed pumping units. However, the pumps in use are over sized for most of the flow demand. One of two existing 300 HP variable speed vertical turbine pumping units (Pump #2) will be replaced with a 75HP inverter duty motor and vertical turbine pump (Pump RP2).

The target efficiencies represent typical efficiencies for standard design vertical turbine pumping units.

4. Where the average of the three guaranteed efficiencies are better than the average target efficiencies, the bid price will be decreased for the purpose of bid selection; if they exceed the target efficiencies, the bid price will be increased.

5. The efficiency guarantee points, and target efficiencies, for each pump are as follows:

Low Flow Guarantee Point Mid Flow Guarantee Point High Flow Guarantee Point Pump GPM Target Eff. GPM Target Eff. GPM Target Eff. EB2 3000 61% 4700 74% 7000 49% B1P 1400 64% 1900 68% 2200 63% RP2 400 62% 750 73% 900 66%

Prior to shipment, the Manufacturer will, on each of the vertical turbine pumping units, install three recording accelerometers: 1) on the middle of the electric motor, 2) on the casing midway between the motor and the pump bowls, and 3) on the middle of the pump bowls. The Manufacturer will secure the accelerometers with a tamper indicating wire and seal or equivalent, digitally photograph the installed accelerometers prior to shipping, and email the photographs to the Engineer.

1.10 RECEIVING

A. The Manufacturer will assume responsibility for equipment, material, and spare parts just before unloading from carrier at site. The Owner will unload the pumps in a designated staging area at each of the two pump station job sites. The Manufacturer will contact the Owner ten business days before delivery with a firm delivery date.

B. Inspect and inventory items upon delivery at job site. Verify the accelerometers have not been tampered with or compromised during shipment. Report the accelerometer readings to the Owner. Any recorded acceleration in excess of 3 times gravitational force (3 g’s) will be evidence that shipping damage may have occurred. Any pumping unit that has received more than 3 g’s acceleration at any point will be disassembled and completely evaluated for mechanical soundness at the Manufacturer’s expense. The Owner will establish the exact evaluation process. Mechanical evaluation will include, but not be limited to: 1. Verify that all impeller and bowl clearances are within factory tolerances, and impellers run

true within the bowls upon manual rotation. 2. Verify that the motor shaft is straight, and motor rotor turns freely and true upon manual

rotation. 3. Verify that the pump lineshaft is straight and within factory tolerances, and the lineshaft

turns freely and true upon manual rotation. 4. Verify that the motor to lineshaft coupling has not been damaged. 5. Verify that all bearings, wear plates, and seals are in the original condition, and show no

visible damage. 6. Disassemble the pump column and verify the column sections are straight, and the

connecting flanges and seals are undamaged and remain within factory tolerances. A complete report of findings will be provided to the Owner. In the event of a dispute between the Owner and the Manufacturer concerning evidence of damage and/or the extent of repairs, a qualified and disinterested third party will review the findings and make the determination of the extent of repairs needed to restore the motor and pump to its original condition. The cost of any corrections needed to restore the equipment to the original specifications will be borne by the Manufacturer. The Owner will withhold final payment until the Owner is satisfied the pump is restored to its original condition.

Vibration shall not exceed 3 mils peak-to-peak at any speed or condition required to meet the Rated Condition Range. Hand held instruments may be used for these vibration measurements.

B. Once the mechanical testing is successfully completed, the Manufacturer shall provide a written certification of proper installation. The final part of the field acceptance testing will be a 7-day operational test by the Owner’s staff. The Manufacturer will provide technical support as requested via telephone, and if telephone support does not resolve any issues satisfactorily and timely, by a site visit at the Manufacturer’s expense. 1. For successful completion of the 7-day operational test, the Owner will be able to operate the

system continuously during the test. The Owner may, at his discretion, simulate the entire Rated Condition Range and Exceptional Condition Range to observe the pumps’ response.

2. If failure occurs, and in the opinion of the Owner, the failure is minor and easily corrected, the Owner will continue the testing. If, in the opinion of the Owner, the failure causes operational difficulties, the Owner will stop the 7-day test and if necessary shut down for repair. The Owner’s decision to stop the 7-day test shall be final.

3. Mechanical failures, revealed during the 7-day operational test, will be corrected by the Manufacturer at their expense.

4. At the discretion of the Owner, a third party will be engaged under separate contract to attach recording vibration meters to the pumps at the top of the motors for the duration of the 7-day operational test. Vibration shall not exceed 2.5 mils peak-to-peak at any speed while the pump is operating within the Preferred Operating Range. Vibration shall not exceed 3 mils peak-to-peak at any speed or condition required to meet the Rated Condition Range or Exceptional Condition Range. Failure to meet vibration limits will require repair by the Manufacturer (including cost of pump removal and replacement if needed).

5. Once any mechanical or vibration failures are corrected, the 7-day operational test will be re-started.

6. Successful completion of the 7-day operational test marks the commencement of the motor and pump warranty period.
