The power of innovation

Working range

Advanced hydraulic design with Dutch roots

The complete design of this pump series, as well as the tools used to make them, are designed and manufactured in the Netherlands. This results in a particularly energy-efficient design that achieves some of the highest scores in the market. The most recent addition to the DPV 125 product range even achieves the highest efficiency in its class.

Other advantages of designing a pump series in house are:

• A hydraulic design adapted to the most common pipe diameters Optimised,
• efficient fluid flow-through specially designed pump base and head piece for high energy efficiency and long life.
• Good Net Positive Suction Head (NPSH) values (0.6 - 5.0 mwk at Q_opt)

Newest vertical centrifugal pump, DPV 125: highest efficiency in its class

Duijvelaar Pumps introduces the DPV 125. Our most advanced vertical multi-stage centrifugal pump for transporting large volumes of drinking and process water.

It is perfect for the increasing demand for a robust, compact and efficient pump with larger capacity (nominal capacity at maximum efficiency: 125 m3/h). Applications include, for example, water transportation, drinking water and fire-extinguishing systems, boiler feed, district heating, or cleaning and washing facilities.The DPI 125 is not only the most energy-efficient pump in the segment, but also flexible due its compact size, and durable due to its quality materials and construction techniques.

Robust design that is safe for drinking water

Reliable and safe operation of a pump comes from a high-quality production process, an optimised design, and the right choice of materials. In the DPV series, this has been translated into:

• Hydraulic section and pump housing completely made from stainless steel
• Choice of stainless steel AISI 304 or 316
• Advanced, highly accurate and reliable production methods using robotics, laser welding and projection welding techniques.
• Conforms to the quality labels: CE ATEX WRas ACS
• Medium-lubricated bearing made from tungsten carbide
• Cast, stainless steel pump base
• Silent, stable and vibration free
  • Extra sturdy pump casing
  • Special design of motor cooling fin and impeller cover
  • Optimised flow through
  • Solid and robust pump housing

Service friendly

60 years experience in the maintenance and production of pumps have led to an optimised pump design that is very easy to maintain.

• Reduction of servicing time and process halt
• Easy-Access and Cartridge Seals,
• motors and pumps are quick to mount and dismount
• Use of standard shaft seals (EN12756)
• Pumps are easily interchangeable one-for-one between DP pumps and other manufacturers
• Easily accessible for servicing, often without the need to disassemble the pump or motor, or any special tools.
• 2 connections/2 x 2 connectors (DPV125), with stainless steel plugs, to make it possible on the suction and discharge side to:
  
  • Pump base drain (without residue), filling, venting and measuring (inlet and outlet pressure separated)
  • Easy to connect equipment to measure pressure differences

Wide number of applications

A DPV pump can be customised so that it is suitable for reliable operation in the most extreme situations:

• Drinking water, light aggressive fluids
• Large choice of motors (or without motor, with optional thrust bearing on the pump) Available in different RAL colours, stained, passivated or electro-polished
• Horizontal mounting up to 7.5 kW with special mounting kit
• Various certification (Lloyds, Veritas, Atex, ABS, GL, DNV) Purchasing and test certificates 2.1, 2.2, 3.1 and 3.2

Applications

• Residential construction
• Utility
• Transportation of cool water
• Hot water applications
• Fire-fighting
• Food, chemical and process industry
• Irrigation
