1Pump introduction

1.1General

The vertical, single or multi-stage centrifugal pump series are designed for pumping clean, or lightly aggressive, watery mediums.

Suction and discharge of the pump are in-line, making the pump easy to install.

The hydraulic assembly is driven by an electric motor. All hydraulic parts of the pump are made of stainless steel.

The vertical multi-stage centrifugal DPV pumps are produced by Duijvelaar pompen.

B/CDesign version

1.3Operation

During centrifugal operation of the pump a negative pressure is created at the inlet of the impeller. This negative pressure 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 diameter of the stages is related to the centrifugal forces and its “stage pressure”: the more stages, the more pressure.

This total capacity and raised 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).

Figure 1: DPVF 85

1.4Measuring, 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 operation. Or to measure the discharge pressure of the pump using a G 3/8 connection.

1.5Working range

The working range is depending on the application and a combination of pressure and temperature. For specific and detailed limits please consult the working ranges as described in the chapter 1.8 Modular selection. The overall working range of the pumps can be summarised as follows:

Table 2: Specification of the working range

Minimum inlet pressureNPSHreq. + 1m

Viscosity [cSt] 1-100 2

Minimum frequency [Hz] 30

Maximum frequency [Hz] 60 4

Allowable size of solids pumped 5µm to 1mm

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 5: Motor load dep. sea level or amb. temp or please contact your supplier for more detailed advice.

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

3.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.

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

1.5.1Minimum capacity

For minimum capacity at medium temperature of 20 oC, see table: Minimum capacity (Qmin); for higher temperatures, see table 3.

To prevent the pump from overheating, gathering gas, cavitation etc. a minimum capacity has to be secured. The minimum capacity corresponds to all percentage of the optimum flow Qopt in relation to the temperature of the liquid pumped.

1.5.2Ambient temperature and higher altitude

If the ambient temperature exceeds the above value, or if 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 below table for the increased percentage of the motor power or contact your supplier for more detailed advice. Table 5: Increase of required motor power

1.7Pump bearing

Medium lubricated stage bearing Tungsten Carbide against Ceramic

Optional pump bearing Tuc/TuC:

In case of severe applications or using conditions, such as hot water, boiler feed (max 140 oC or when the pump experiences un avoidable dry running for a short time. The standard ceramic bearing material can be replaced / exchanged by a more resistant TuC/TuC bearing material.

Due to the specific material characteristics of Tungsten Carbide, the TuC/TuC material is even more resistant for the above mentioned severe conditions and will enhance the durability and lifecycle of the pump.

1.6Basic material variants

VC 851.4301JL1040EPDM

When combining the use of the optional TuC/TuC bearing material and the optional low NPSH kit, the pump can be made even more suitable for the above mentioned severe applications or using conditions.

The optional combinations TuC/TuC bearing material and low NPSH kit are available for the vertical pump models DPVCF 2,4,6,10,15, 25 and 40.

Up to now only the optional TuC/TuC bearing material is available for pump models DPVCF 2 up to and including 125.

For other possible pump options or features, please contact our sales department.

1.8Modular selection

To suit almost every application the pump is assembled 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.

Temperature range -20 up to 140 oC, with the exception of the DPV 125 this pump can be used upto 120 oC.

• Connections, which define the suction and discharge connection as well as the base plate. VE casing (with non return valve) max. temperature 90 oC. Other connections have same temperature range as basic pump model.

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

Temperature range, see chapter 5.1

• Electric motor, which defines all requirements of the motor such as motor size, power, voltage, frequency and all possible motor accessories. Due to mono-block motor version VM, max. fluid temperature is 60 oC

1.9Approvals

CE Conformity with European Safety Directive

ACS Drinking Water Approval (F)

WRAS Drinking Water Approval (GB)

ATEX Conformity with “ATmosphères EXplosibles” Directive

2Performance characteristics

2.1Performance range

2.2Performance curve details

The performance diagrams give a global overview of all the pump models the shaded models are mentioned in this documentation. Detailed characteristics are given for each model showing the hydraulic efficiency, NPSHreq, and shaft power as well.

The performance of the pump depends on the number of stages. As per example:

DPV 4/2 B:model DPV 4 B2 stages with 2 full head impellers

DPV 85/4-1 Bmodel DPV 85 B4 stages with 3 full head impellers and 1 reduced impeller

The detailed performance curves are in accordance with ISO 9906: 2012 (Grade 3B).

The motors used for the measurements are calibrated motors with a specific rotational speed. Therefore the performance data, like Q/H, efficiency and shaft power used for published curves are converted to the average speed per motor power. To refine this data the published data has to be corrected accordingly.

The published curves and data mentioned on the pump are based on the following rotational speed:

The characteristics given are based on:

• De-aerated water at a temperature of 20 °C

• Density of 1,0 kg/dm3

• Kinematical viscosity of 1 mm2/s (1 cSt)

Figure 2: Performance range DPV(C/S) B/C 60Hz

2.3Minimum efficiency index

The minimum energy-efficiency level according to ErP regulations for water pumps is specified by the minimum efficiency index MEI. A high value indicates a high efficiency of the determined pump. From 1 January 2015 on the minimum efficiency index (MEI) for standardised water pumps is ≥0.4.

The following MEI values apply for the pump range design version B/C:

Table 7: Minimum efficiency index

Pump range

DPV 2BMEI ≥ 0.70

DPV 4BMEI ≥ 0.70

DPV 6BMEI ≥ 0.70

DPV 10BMEI ≥ 0.70

DPV 15CMEI ≥ 0.70

DPV 25BMEI ≥ 0.70

DPV 40BMEI ≥ 0.70

DPV 60BMEI ≥ 0.70

DPV 85BMEI ≥ 0.60

DPV 125BMEI ≥ 0.70

2.4Performance with variable frequency drive

The minimum frequency of the DP motor should be limited to 30Hz. 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 performance of the pump differs from the fixed speed performance according to the recalculation scheme.

2.5How 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:

AFlow determined (like booster sets and cleaning) Opening taps

BPressure determined (like boiler feed and reverse osmosis systems) Facing counter pressure.

How to read the motor power

The required motor power can be read in the curve’Power input’.

Attention: the power value as mentioned in this curve is the required power per stage. For some pump types there are two lines in the curve this is related to the full impeller or reduced impeller [-1].

3Low NPSH impeller

3.1General

Low NPSH impeller

For the pump type series DPV(S/C)(F) 2, 4, 6, 10, 15, 25 and 40 it is now possible to have a low NPSH solution as option. This solution based on a new designed low NPSH impeller and modified stage casing the NPSH curve of the pump will have much better values throughout its raster. This can prevent cavitation in the pump in case of critical inlet conditions.

Cavitation is the process of forming vapour-filled cavities within the liquid in areas where the available pressure has been reduced below a certain critical value. This also happens in case the pressure drops below the vapour pressure of the liquid. When the pressure raises these cavities will implode to become fluid again. These implosions generate pressure waves which are transmitted to the surfaces of the hydraulic pump parts and can damage the material. This phenomenon is called incipient cavitation and is characterized by a metallic noise produced by the hammering on the material.

3.2Risks of cavitation:

Reduced lifetime of the pump due to damaged parts and unbalanced hydraulics.

Excessive wear of pump parts or motor bearings. Insufficient cooling and/or lubrication of the mechanical seal and pump bearing.

3.3Benefits of using low NPSH impeller:

More suitable in critical inlet conditions.

Easy adaption to non-optimized application parameters.

The suction lift (Hp) can be less critical (e.g. the frame height of the de-aerating tank in case of boiler feed can be reduced)

3.4Consequences by using a low NPSH impeller:

No change in pump height or connection.

Slight adjustments on the performance curve, see curves as published on pages 32 to 42.

3.5Calculation of NPSHa

Calculation NPSHa > NPSHr + 0,5

Check if cavitation can be expected.

Hb + Ho + Hp - HV - Hi > NPSHr + 0,5

Hb = barometric pressure in mwc

Ho = over pressure (in case of closed tank) in mwc

Hp = suction lift in mwc

Hv =- vapour pressure in mwc

Hl = friction loss in pipe work and accessories in mwc

NPSHr = net positive suction head of the pump

0.5 = safety factor

Table 8: Calculation NPSHa

Atmosferic pressure + 10.3 mwc

Overpressure in degassing tank + …… .mwc

Positive height of degassing tank or vessel + ……. mwc

Vapour pressure of feed water (see table)in degassing tank in case of boiler feed - ……. mwc

Loss of pressure in suction piping and strainer - ……. mwc

Safety factor - 0.5 mwc

NPSHr at duty point (see pumpcurve) - ……. mwc

Minimal positive pressure x mwc

If 'x' is positive there is no cavitation to be expected

If 'x' is negative cavitation can be expected, to avoid this the low NPSH impeller could solve this problem. Otherwise one of the other values can be changed so the outcome will be positive.

7Accessories

7.1Thrust bearing housing (optional)

Figure 32: Thrust bearing housing

The standard Duijvelaar pompen motors are specially designed to drive the pump. When a standard motor has to be installed (or a special motor to fulfil the applications requirement, like explosion proof, high efficiency) a special bearing housing must be installed to relieve the motor of the axial force created by the pump.

ATTENTION

This option is not applicable for pump model DPVM.

ATTENTION

Only a motor with a standard key can be installed with a thrust bearing housing.

ATTENTION

There is no need to change the motor stool of the pump. The bearing flange can be mounted on the standard motor stool of the pump.
