DYNASET HPW-pump is a converter, which transforms actuating fluid power, usually hydraulic oil, into
pumping fluid's power, which is defined by flow rate and pressure. Actuating power is supplied from hydraulic
system of carrier machine or other installation. Water or any other pumping fluid can be taken from natural
source, reservoir or pressurized supply network.
The patented HPW-pump utilizes the reciprocal motion of hydraulic piston, when two water plungers, flanked
to it, develop pressure in delivery (pressure) line. Hydraulic flow moves the piston assembly until the other
water plunger reaches its extreme position, when changes the incorporated reversal valve direction of
hydraulic flow and, by that, the piston assembly is being set to counter direction. Vacuum is being developed
into pumping fluid's intake line and positive pressure in delivery line accordingly. Within pumping cycle water
(or other pumping fluid) is being taken by water plungers through intake valves and pumped through pressure
valves into delivery line.
Relation of pumping fluid's flow rate and pressure to corresponding parameters of hydraulic fluid is linear, as
shown on diagrams below.
When hydraulic pressure and/or flow is under the value needed to achieve the maximum output power of
HPW-pump, the water pressure and flow are decreased respectively without any harm to pump itself.
ATTENTION !
Most of HPW-pumps are self-priming. Specific characteristics of any pump can be verified according to the
technical specification (see last page).
THE DESIGN OF HPW-PUMP IS PROTECTED WITH THE INTERNATIONAL PATENT.
PUMPING FLUID TO HYDRAULIC FLUID RELATION, CONCERNING THEIR FLOW RATES AND PRESSURE.

DYNASET HPW-pumps are compact and integrated all-in-one units, designed for both mobile and workshop
installation. HPW-pumps perfectly work installed on excavators, mining machines, tractors, trucks and vans.
In workshop use HPW-pump is accompanied with hydraulic aggregate.
DYNASET HPW-pump can be positioned deliberately, keeping in view following preconditions:
1. Easy service access to the unit should be ensured.
2. Pump should be mounted on sufficiently horizontal surface to enable proper working of leakage detecting
bores, which are found either on bottom surface or side faces of pump housing (depends on model).
Leakage detecting bores are made to the zones, which separate oil and water chambers from each other.
If the draining from leakage detectors exceeds rate of 10 drops per minute, pump sealings should be
replaced. The drain fluid can be water, hydraulic oil or their solution.
You can choose deliberately how to make pump's installation to your carrier: either fixed or as a quick
release unit. In latter case HPW-pump is easily detached and re-attached to carrier's hydraulic system with
quick couplings, when pump can be moved from one carrier to another when necessary.
