customers have trusted the innovative DPV stainless steel multi-stage
centrifugal pumps series in diverse applications for the transportation of
their process water. Energy efficient through smart hydraulic design; reliable
through the use of high-quality materials and manufacturing; and versatile due
to the unique modular concept that offers an almost infinite number of
variations in materials, seals, connectors, motors, etc.
The pumps in
the range can be used stand-alone pump for the supply of water to fire extinguishing systems or be assembled into a Fire-Unit with multiple pumps.
Head (H): 5 - 254 mwc
Flow (Q): 1,90 - 125
Ambient temperature: -20 - +40
Liquid temperature: -20 - +140
˚C. DPV125 max +120 ˚C
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
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 Qopt)
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
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
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
3,000,000 possible variations
The DPV series
is a modular series of pumps that can be customised in countless numbers of
Hydraulic (multiple steps/diameters) and motor (power/rpm) match
the application exactly.
Wide variety of pump bases, connections and seals.
Pressure class PN16, 25, 40
Cast iron (VCF) stainless steel AISI 304/316
More than 10 material combinations for seals
Seals can be adapted to application:
Fixed, for long-life expectancy
of the seal
Easy access, for medium lifetime
in combination with quick replacement
Cartridge, for demanding
applications under high pressure in combination with quick replacement
Compact design with integrated check valve in the base and
extended motor shaft (E-version)
Short, to extremely short, delivery times made possible by the
modular production system
