DYNASET HIGH PRESSURE PUMP HPW 1200/100-440 -pump is 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 above and below seal disc the surface, see blue arrows. We recommended to using
eight (8) bolts to secure reliable fastening. 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 sealing’s should be replaced.
The drain fluid can be water, hydraulic oil or their solution.

HIGH PRESSURE PUMP HPW 1200/100-440
March 2013 JLe
HPW-pump is to be connected to hydraulic system of carrier machine, as well as to pumping fluid circuit.
HPW can be installed with no particular efforts to system based on either constant or variable displacement
hydraulic pump, as well as to closed hydraulic systems.
1. HYDRAULIC SYSTEM WITH CONSTANT DISPLACEMENT PUMP:
The required oil flow is set by correct dimensioning of the hydraulic pump and keeping the demanded
rotation speed or, alternatively, with pressure compensated 3-way valve.
2. HYDRAULIC SYSTEM WITH VARIABLE DISPLACEMENT PUMP:
A. In system with OPEN CENTRE the required oil flow is set by DYNASET PRESSURE COMPENSATED
PRIORITY VALVE
B. In system with CLOSED CENTRE (load sensing system) the required oil flow is set by
DYNASET LS-VALVE kit, which comprises solenoid valve, pressure compensated oil flow limiter
and pressure relief valve.
