anodized aluminum
•Adjustment: Fine volumetric pressure and
vacuum adjuster
•Pressure Relief Valve: Adjustable from 0.7 to 45
psi / 50 mbar to 3 bar
•Construction: Nylon, stainless steel, brass, PTFE,
and nitrile

A Release valve. Use to reduce or release pressure in the
system. The rate of pressure reduction depends on the
degree of rotation when opening the valve. Minimal force
is required to seal the system.
B Fine adjustment control. Turn in or out to increase or
decrease pressure accordingly.
Caution
To avoid damage to the pump, do not wind the fine
adjustment any further when the top of the pump
body is visible.
C Pressure/vacuum selection. Press the selector as
indicated on the label to engage the desired mode. Make
sure that the release valve
A is fully closed (clockwise
motion) prior to pumping.
D Quick-fit connectors. Fit the hose E and adapters F
by screwing them into the connectors D by turning the
knurled nut on the connector fully counterclockwise.
E Hose.
F Quick-fit Adapters. 1/4 BSP female & 1/4 NPT female.
Use flat seals with BSP threads. Use PTFE with NPT
threads.
G Pump Handle. If the pump has not been used for a
while, there may be some resistance on the first stroke.
H Pressure Relief Valve. The maximum output pressure
can be set by adjustment of the pressure relief value
located inside the main piston. Access to the adjustment
screw is through the hollow-handle retaining screw.
Using a small screwdriver, turn adjustment screw
clockwise to increase pressure, and counterclockwise to
reduce pressure.

Guidelines for Use
1. Connect a presssure calibrator or pressure
module to the quick-fit connector (4) at the end of
one of the flexible hoses (5).
2. Connect the unit under test to the quick-fit
connector (4) at the end of the second flexible
hose (5), choosing correct adapters (6) and seals.
3. Screw fine adjustment control (2) in fully.
4. Screw fine adjustment control (2) out 4-6 full
turns.
5. Screw pressure release valve (1) in fully,
tightening to ensure good seal.
6. Operate handle (7) until the pressure is close to
that finally required.
Notes
•The pressure may settle for up to one minute
after increasing pressure due to the
thermodynamic effects, settling of seals and
expansion of the flexible hose.
•On very high resolutions such as 1 mbar or
0.1 inches of water, small movements of the
tubing may result in noticeable pressure
changes.
Caution
To avoid damage to the pump, do not wind
the fine adjustment (2) any further when the
top of the pump body is visible.
7. Turn the fine adjustment control (2) in to increase
pressure or out to decrease pressure until
required pressure is reached.
8. Reduce pressure by careful use of the pressure
release valve (1).
9. Achieve vacuum using the above procedure with
the pressure / vacuum selector (3) pushed
completely towards the vacuum position.
Caution
To avoid damage to the sealed joints, do not
attempt to tighten other fittings to the pump.
When testing for leaks, you may notice that air is
drawn in or expelled from around the pressure /
vacuum selector. This is normal and should cause no
concern.
If the pump appears to lose pressure, then the
procedure above should be repeated, ensuring new
seals are used, adapters are tightened sufficiently and
the pressure release valve (1) is tightened firmly. The
connections to the handheld test system are sealed
with O-ring or bonded seals and should not leak.
