Hi-Force HP110 Operating Instruction

Prepared by:- M.Davies
REV NO:-
ECO:- 4282

INTRODUCTION

The HP110 AND HP145 single speed hand pumps are manually operated hand pumps suitable for a wide range of
applications. Both pumps are supplied complete, with a pre-filled oil reservoir ready for immediate use. They
features low handle effort characteristics for easy operation, a lightweight design and is of strong durable steel
construction. The HP110 and HP145 have a max working pressure of 700 bar.

SAFETY NOTES

All equipment used must be rated for the same operating pressure i.e 700 bar. (10,000 psi). DO NOT mix high and
low pressure components. If in doubt contact your local Hi-Force Distributor.
Sufficient time should be allocated to planning your hydraulic system. Make sure that all system components are
adequate for the intended operation.
Ensure that the pump has sufficient oil capacity to operate the cylinder being used.
DO NOT exceed the rated pressure of the pump or rated capacity of the cylinder. Never tamper with the internal
safety relief valve of the pump.
Whenever possible use a pressure gauge in the system to prevent overloading.
The pump must only be used on single acting cylinders

TEST, EXAMINATION AND SERVICE.

1.
Visually inspect all equipment before use for signs of damage or wear and tear. Any defective or suspect
equipment should be repaired or replaced immediately.
2.
All high-pressure hydraulic equipment should be thoroughly examined and proof tested by a competent
engineer at least once a year - more frequently for heavy use.
3.
Ask your Hi-Force distributor about the full Hi-Force Repair facilities and the Hi-Force Test and Examination
Service - available for all makes of high-pressure hydraulic equipment.

HOSE CONNECTION.

1.
Hose connections are 3/8NPT and must be properly tightened using a quality pipe thread sealant or 1-2 turns of
P.T.F.E tape taking care NOT to allow loose ends of the tape to enter the hydraulic system. DO NOT over
tighten connections - it can cause premature failure or rupture of fittings at below rated capacity.
2.
Connect the male couplers on the hose ends to the female couplers on the cylinder. Ensure that both halves of
the coupler are completely clean so that no dirt can enter the system. Fully tighten the two halves of the coupler
by hand only – do not use tools.
1. The pump may be used either horizontally or vertically with the hose end downwards. The pump is equipped
with a pressure relief valve factory set at the maximum operating pressure. Before use unscrew transit plug
and replace with breather on the top of the tank. This will maximise the oil volume available. (HP110 used in all
diagrams.)
