HPX1500 – HPX2800 Ultra High Pressure Manual
Pump.
INTRODUCTION
The operating and maintenance procedures
listed within this manual should be adhered to
and will enable the operator to obtain
maximum efficiency and reliability from the
equipment.
PRECAUTIONS
Prior to connecting the hydraulic pump to any
equipment, the user is to ensure that:-
The working pressure of the hydraulic pump
and the equipment to be operated are
compatible.
The reservoir pump capacity is adequate to
operate the equipment throughout its range.
The hydraulic oil specifications used within
the pump and the equipment are compatible.

RECOMMENDED OIL
Hydraulic oil, viscosity class ISO 32
Prior to use:
Operate the handle with the Release valve
open as shown in figure 1. This will assist in
bleeding the pump of air trapped in the
system.
Figure 1:
During test and operation of the pump it is
recommended that a length of hose is either
connected to a tool or terminated with a
coupling and blanking plug is connected to
the pump.
This assists in moving a reasonable quantity of
oil from the pump prior to pressurising and
prevents air from gathering and being trapped
in the system.
Description of Pump Operation:
A dual piston system which delivers low
pressure or high pressure throughout the pump
stroke. The system switches automatically
between low and high pressure to ensure
maximum efficiency whatever the load.
Safety Feature:
The pump is equipped with an internal tamper
proof safety valve that regulates the maximum
working pressure. The safety valve is set to the
maximum pump working pressure and is
factory pre-set.
Installation
General
Always check that hoses, couplings, cylinders
and tools, etc; that are connected to the
pump are designed for use at a working
pressure that equals or exceeds the maximum
working pressure of the pump.
Connecting the hydraulic hose
Connect the hydraulic hose using a G 1/4"
coupling, or use a Hi-Force quick coupling,
tightening to a maximum torque of 40–50
Nm. Air can become trapped in the hydraulic
system when you connect hoses and tools, and
this can lead to problems with operation. Refer
to the heading Bleeding the hydraulic system
.
