1. If the ambient temperature exceeds the above value or the motor is located more than 1000 m above sea level, the motor cooling is less effective and could require an adapted motor power. See table 9: Motor load dep. sea level or amb. temp or please contact your supplier for more detailed advice.

2. High temperature or high pressure could require a special pump selection, see 3.9: Sealing.

3. Deviation in viscosity and/or density could require an adapted motor power. Please contact your supplier for more detailed advice.

4. The free space above the motor cooling fan must be at least 1/4 of the diameter of the inlet of the cooling fan in order to have a sufficient flow of (cooling) air.

5. Pumps that are intended for 50 Hz operation, may not be connected to 60 Hz power supply.

1.7 Mechanical shaft seal

Single acting mechanical seal acc. EN 12756. Exchangeable without disassembling the pump and removing the motor.Standard in “Easy access” construction for applications with a medium/long expected life span of the mechanical seal.Optionally as “Cartridge” available for applications on which a short life span of the mechanical seal is to be expected.

1.8 Modular built-up

To suit almost every application the pump is built-up out of modules which can be selected depending on the required working range.Basic modules are:

• Basic pump model, which defines the capacity, pressure and basic material

• Connections, which defines the suction and discharge connection as well as the base plate.

• Sealings, which defines the elastomers, the mechanical seal and the shaft seal type.

• Electric motor, which defines all requirements of the motor such as motor size, power, voltage, frequency and all possible motor accessories.

For detailed selection, see 3.11 Motor options.

1.10 Operation At the centrifugal operation of the pump an underpressure is created at the inlet of the impeller. This underpressure enables the medium to enter the pump at the suction connection (A).Every stage (B) consists of an impeller and diffuser The passage of this stage determines the capacity of the pump. The stages diameter is related to the centrifugal forces and its “stage pressure”: the more stages, the more pressure.This total capacity and built-up pressure will be guided to the outside of the pump, between the pump stages and the outer sleeve (C) and the medium will leave the pump at the discharge connection (D).

1.11 Measuring, draining and venting

The pump is provided with plugs for measuring, draining and venting.Connection (E) is meant to drain the inlet part of the pump. Or to measure the inlet / suction pressure using a G ¼ connection.Connection (F) is meant to drain the outlet part of the pump. Or to measure the discharge pressure using a G ¼ connection.Connections (G) are meant to vent the pump system when the pump is not in operatio. Or to measure the discharge pressure of the pump using a G 3/8 connection.

2 Performance characteristics

2.1 Performance curve details

The collective diagrams give a global overview of all pump models mentioned in this documentation.Detailed characteristics are given for each model showing the hydraulic efficiency, NPSHreq, and shaft power per stage.The performance of the pump depends on the number of stages. The number of stages are shown as “/3” , as per example:DPVF 85/3: 3 full stagesDPVF 85/3-1: 2 full stages, 1 stage with reduced head impeller (upper stage)

The detailed performance curves are in accordance with ISO 9906 Annex A. Vibration limits at rated

speed and rated flow are according to ISO 9905.

The motors used for the measurements are standard DP. When using another motor brand the performance data, like Q/H, efficiency and shaft power must be corrected accordingly.

The characteristics given are based on:• De-aerated water at a temperature of 20oC• Density of 1.0 kg/dm3

• Kinematic viscosity of 1 mm2/s (1 cst)To prevent the pump from overheating, gathering gas, cavitations etc., a minimum flow has to be secured.

2.2 Performance with variable frequency drive

The minimum frequency of the DP motor should be limited to 10 Hz to ensure sufficient cooling. When the rotational speed exceeds the nominal speed of the motor, make sure that the power output of the motor is suitable to drive the corresponding pump model.

The converted frequency from an average variable frequency drive will have a rather high pulse rise time, which creates heat in the winding. To be suitable for this kind of application, the DP motors are built in accordance with IEC 60034-17.

2.3 Performance using other brand of motors

Using other brands of motors having their own rated speed which differ from the standard dp-motors the exact Q/H has to be calculated, using the calculation formular “divergent speed”.

2.5 How to read the values from the curves

To find the required hydraulic information from the published curves, it is important to know the application in which the pump has to be installed.There are two main distinction to be made:A Flow determined (like booster sets and

cleaning) → Opening tapsB Pressure determined (like boiler feed and

reverse osmosis systems) → Facing counter pressure.

3.9 Sealing

The DPVF 85 can be fitted with an Easy Access seal or a cartridge seal.At selection of the seal, the following parameters must be taken into account:• Pumped medium• Medium temperature• Maximum pressure• Expected life span

In the following diagram the right seal type can be chosen, depending on the temperature and pressure class.The temperature is given as an absulute value and as ΔT: The deviation from 20 °C room temperature
