The Tensioner Pump consists of the following
components:
Air Filter
Ensures that a clean, dry air supply is maintained. Any
water is collected in the bowl and can be drained off by
turning the filter drain screw clockwise.
Air Regulator
Complete with its own pressure gauge, regulates the air
pressure to the pump. To increase air pressure, screw
the air regulator into its body.
Air Lubricator
Lubricates air supply and should be set to give one drop
for every 40 strokes of the pump, by turning adjusting
the red knob. Top up when required using a lubricating
oil of ISO Viscosity Grade 10.
Air Flow Valve
Controls air supply to pump and gives variable pump
speed control.
Reservoir
Capacity 8 litres, has coarse filter at filler neck and fine
filter at outlet pipe. Level indication tube should be at
least half full. Top up when required using an anti-wear
hydraulic oil of ISO Viscosity Grade 22-68. Appropriate
viscosity grades of oils shall be selected dependant on
operating temperatures.
Oil Return-to-tank Valve
When open allows oil to flow back to reservoir. To open,
turn handle anti-clockwise.
Pump
Piston type unit. Full breakdown details and spare seal
kits available on request.
Oil Pressure Gauge
0-1700 Bar (0-25,000 psi). Accuracy should be checked
and calibrated periodically.
Oil Outlet Connection
Quick release type, which is self-sealing to prevent dirt
penetration and oil drips.
Air Inlet Connection (not shown)
Standard 1/2 inch, reduced to 1/4 inch BSPT, via an
adaptor.
The pump is shipped from the factory without
hydraulic oil. Add hydraulic oil before operating the
pump! Use ISO Viscosity Grade 22 Minimum-68
Maximum.
