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 capac-
ity 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)

2. SAFETY INFORMATION
The operator MUST read this manual prior to using the tools.
Failure to comply with the following cautions and warnings could cause equipment
damage and personal injury; read the manual fully!
Read all the following instructions, warnings and cautions carefully. Follow all safety
precautions to avoid personal injury or property damage during system operation.
Equalizer International Ltd cannot be responsible for damage or injury resulting from unsafe
product use, lack of maintenance or incorrect product and/or system operation. Contact
Equalizer International Ltd when in doubt as to the safety precautions and applications. To
protect your warranty, use only good quality hydraulic oil of the grade 15cSt.
Only people competent in the use of hydraulic equipment should use these tools.
In all installations the site safety requirements must be adhered to. ALSO the safety of the
operator, and when present, any assisting personnel, is of paramount importance along with
the safety of others including, when present, the general public.
These instructions are only to cover the safe operation of THE EQUALIZER HP350S, HP550S,
HP1000S, HP350D, HP550D and HP1000D HYDRAULIC SEALED HAND PUMPS during normal
maintenance/installation operations. All other safety aspects must be controlled by the
operation supervisor.

OPERATOR INSTRUCTION MANUAL PAGE 3
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. Over-
loading causes equipment failure and possible
personal injury.
CAUTION: Make sure that all system compo-
nents are protected from external sources of
damage, such as excessive heat, ame, mov-
ing 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 pre-
mature 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 hos-
es. Escaping oil under pressure can pen-
etrate 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 equip-
ment by the hoses or couplers. Use the car-
rying handle or other means of safe trans-
port.
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
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

6. INSTALLATION AND OPERATION
WARNING:
Never attempt to pressurise the pump when the pressure gauge is not
connected or the pump is not connected to a system!
DANGER:
Always check the hydraulic system in which the pump is to be used is rated
for 10,000 psi (700 bar). Over pressurising a hydraulic system will result in
component failure and personal injury!
2. Ensure the hydraulic system you
wish to pressurise has been bled
and is free from air and leaks.
Connect the pump into the system
using the screw connector supplied
with the pump, push the male and
female connectors together fully and
rotate the locking ring clockwise
until fully tight.
WARNING:
Never disconnect the pump
or other components when
the system is pressurised

3. Close the release valve fully by
rotating clockwise until hand tight
4. Pressurise the system by raising and
depressing the pump handle until
the desired pressure is indicated
on the pressure gauge
N.B. max. pressure 10,000 psi (700
bar)
5. To depressurise the system, gently
open the release valve by rotating
the release knob anti-clockwise
6. Once the system has been fully
depressurised, the pump can be
disconnected by unscrewing the
connectors.
