DOUBLE ACTING HYDRAULIC
SEALED HAND PUMPS

6.
Pressurise the retract hose by raising
and depressing
the pump handle with the control lever in the retract
position until the desired pressure is indicated on the
pressure gauge N.B. max. pressure 10,000 psi (700
bar)
7.
To keep pressure in both hoses, set
the control lever
in the central vertical position.
8.
To depressurise both hoses, set the control lever in
the advanced position until the gauge indicates zero
pressure and then set the control lever in the retract
position until the gauge indicates zero pressure.
9.
Once both systems have been fully depressurised
the pump can be disconnected by unscrewing the
couplers.

USE OF EQUALIZER INTERNATIONAL
TOOLS WITH A HYDRAULIC MANIFOLD
Using the hydraulic manifold enables more than 2 tools to
be used simultaneously from a single pump. The function
of a manifold is to share the hydraulic output of one pump
evenly between multiple tools, ensuring that all tools have
equal pressure so can be used together in sharing the
load.
USAGE GUIDELINES
•
Ensure the manifold, the tools and the pump have the
same hydraulic pressure rating.
•
Do not pressurise the manifold unless all couplers
are connected to tools or positively blanked off using
appropriate pressure fittings; do not rely on the
manifold valves or couplers to hold hydraulic pressure.
•
Isolate individual tools by turning the corresponding
Control Knob clockwise until tight. Isolating a single
tool will disconnect it from the rest of the tools and
the pump, maintaining whatever hydraulic pressure is
currently within the tool and the hose.
•
Isolating individual tools can allow some degree
of differential control between manifolded tools,
enabling different pressures or positions to be held
for each tool, for example in controlling alignment.
•
To return an isolated tool to the shared pressure of
the manifold, slowly loosen the corresponding Control
Knob anti-clockwise fully. Any pressure in the tools,
manifold or pump will be balanced out and may result
in an increase or decrease in pressure of any given
tool.

IMPORTANT: there is a risk of back-loading individual
tools when manifolded. To mitigate this risk, ensure
all Control Knobs are fully open before releasing pump
pressure!
