1. INTRODUCTION
The Equalizer HP-S hydraulic single-port sealed hand pump and HP-D hydraulic twin-port
sealed hand pump replace the Equalizer P142 hydraulic hand pump.
The HP350S, HP550S, HP1000S, HP350D and HP550D and HP1000D are tailored for use
with Equalizer International Ltd hydraulic equipment. Their output is regulated to 700bar
(10,000psi) and is delivered from an output port threaded ⅜” NPT. The HP350S and HP350D
can be used with any 700 bar (10,000 psi) rated hydraulic equipment with an oil capacity of 350cc (21.35 in3) or less. The HP550S and HP550D can be used with any 700bar
(10,000psi) rated hydraulic equipment with an oil capacity of 550cc (30.51 in3) or less. The
HP1000S and HP1000D can be used with any 700bar (10,000psi) rated hydraulic equipment
with an oil capacity of 1000cc (61.0 in3) or less.
The diaphragm oil reservoir means that, unlike conventional hand pump units, the HP-S and
HP-D pump ranges are operable at all angles and are highly resistant to accidental spillage of
hydraulic uid.
Pressure rating:
● 1st stage: 13.8 bar (197 psi)
● 2nd stage: 700 bar (10,000 psi)

A CAUTION is used to indicate correct operating or maintenance procedures and practices to
prevent damage to, or destruction of equipment or other property.
A WARNING indicates a potential danger that requires correct procedures or practices to avoid
personal injury.
A DANGER is only used when your action or lack of action may cause serious injury or even
death.
IMPORTANT: Operator must be competent in
the use of hydraulic equipment. The operator
must have read and understood all instructions,
safety issues, cautions and warnings before
starting to operate the Equalizer equipment.
WARNING: To avoid personal injury and
possible equipment damage, make sure all
hydraulic components are rated to a safe
working pressure of 700 bar (10,000 psi)
WARNING: Do not overload equipment. Overloading causes equipment failure and possible
personal injury.
CAUTION: Make sure that all system components are protected from external sources of
damage, such as excessive heat, ame, moving machine parts, sharp edges and corrosive
chemicals.
CAUTION: Avoid sharp bends and kinks that
will cause severe back-up pressure in hoses.
Bends and kinks lead to premature hose failure.
Do not drop heavy objects onto hoses. A sharp
impact may cause internal damage to hose wire
strands; applying pressure to a damaged hose
may cause it to rupture. Do not place heavy
weights on the hoses, or allow vehicles to roll
over the hoses; crush damage will lead to premature hose failure.
WARNING: Immediately replace worn
or damaged parts with genuine Equalizer
parts. Equalizer parts are designed to t
properly and withstand rated loads. For
repair or maintenance service contact your
Equalizer distributor or service centre.
DANGER: To avoid personal injury keep
hands and feet away from the tool and
workpiece during operation.
WARNING: Always wear suitable clothing
and Personal Protective Equipment (PPE).
DANGER: Do not handle pressurised hoses. Escaping oil under pressure can penetrate the skin, causing serious injury. If
oil is injected under the skin, seek medical
attention immediately.
WARNING: Never pressurize unconnected
couplers. Only use hydraulic equipment in
a connected system.
IMPORTANT: Do not lift hydraulic equipment by the hoses or couplers. Use the carrying handle or other means of safe transport.
CAUTION: Do not operate the equipment
without lubricating all moving parts. Use
only high pressure molybdenum disulphide
grease.

5. HOW THE HAND PUMPS WORK
1. The release valve is closed fully by
rotating clockwise until hand tight
2. The pump handle is raised, which
creates a vacuum in the piston
chamber which sucks oil from the
reservoir into the chamber
CLOSE RELEASE
VALVE
3. The pump handle is depressed,
which pumps the oil from the
chamber through the outlet port
and into the system to which the
pump is connected
4. Steps 2 & 3 are repeated, which will
pump oil into the system until the
maximum pressure of
10,000 psi (700 bar) is achieved, at
which point the safety release valve
will open and the oil will cycle back
to the reservoir

10. TROUBLESHOOTING
Problem: Hoses are connected but the tool does not advance. The pressure on the pump handle is minimal.
The release valve is in the retract
(open) position (and the control
valves are open on the HP-D)
Problem: Hoses are connected and the pump quickly reaches maximum pressure but the tool has not advanced
One or more of the connectors are
not fully tightened and the
hydraulic oil cannot pass through
from the pump to the cylinder
Problem: Hoses are connected and the tool advances but there is minimal pressure on the pump handle and the
xxxxxxxxxhandle is rising back of its own accord
There is dirt or a damaged valve
seat within the pump unit
Close the release valve (and the control valves
on the HP-D)
Check all connectors are fully tightened and the release valve is in the
fully closed position
The pump should be sent to an authorised Equalizer distributor for repair

Problem: The tool the hand pump is driving is advancing but does not reach full pressure
Air could be present in
the hydraulic system
Use the airlock removal
procedure as follows:
1. Connect the hand pump to the
tool with the hydraulic hose
2. Close the release valve on the
pump, and prime the pump
until the hydraulic cylinder
is fully extended and a small
pressure is achieved
3. With the hand pump held
above the tool and the tool
in an upright position, open
the release valve causing any
air that is within the system
to be forced up through the
pump and vented into the oil
reservoir
4. Repeat steps 1 - 3 three or
four times to ensure that all air
is removed from the system
and the tool will reach full
working pressure
5. Disconnect the hand pump
from the hydraulic hose, grip
the baseplate of the hand
pump body in a vice with the
pump body vertical and the
main handle at the top

6. Remove the four nuts holding
the main handle and lift off
7. Grip the relling plug with
pliers and extract it by pulling
and twisting simultaneously.
Ensure the reservoir body is
held down when removing the
relling plug as pulling up on
the reservoir body will release
the bladder within, and oil will
spill out.
8. Fill the reservoir to the top with
a good quality hydraulic oil of
the grade 15 cSt
9. Reinsert the relling plug, wipe
away any oil, and reassemble
by reversing the disassembly
process
