1. INTRODUCTION
The HP350SD, HP550SD and HP1000SD Hydraulic Hand Pumps output is regulated to 700
bar (10,000 psi) and is delivered from an output port threaded ⅜” NPT. The HP350SD,
HP550SD and HP1000SD can be used with any double acting 700 bar (10,000 psi) rated
hydraulic equipment.
The diaphragm oil reservoir means that, unlike conventional hand pump units, the HP350SD,
HP550SD and HP1000SD 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.
