AHP3 SERIES – Hydrotest Pumps:

1.0 General Description

The Hi-Force AHP3 range of Hydrotest pumps

are supplied in a range of 3 models with output

pressures ranging from 42 bar(609psi) to 700bar

(10000psi) and are suitable for use with various

fluids including water.

2.0 Before operating your Hi-Force Hydraulic

Power Pack please ensure that the following

instructions are carried out.

Connect the liquid supply to the pump

inlet port (1 ¼" NPT.) This is normally from a

reservoir tank.

Ensure that the liquid is filtered before

reaching the pump unit liquid inlet port.

Hydraulic oil (ISO 10 or 32) or water

can be used. When using water, a Glycol

additive to the water will reduce seal wear in

the unit.

Check the air lubricator bottle is filled

(use any light grade lubricating oil –SAE 15). To

top up undo the screw on top of the bottle and

top up.

(Important Safety note: Ensure the air supply is

disconnected when filling the bottle.)

The lubricator is factory set to deliver 1

drop every 25 strokes of the pump. The red

knob is used to affect this setting.

Connect the air supply line to the

pump inlet (1/2" BSP) Min recommended pipe

size ½ bore. Air requirement is 70-100psi, 56

S.C.F.M. Ensure the air on/off valve is closed.

The item requiring hydraulic pressure

connection may now be connected to the

outlet block. ½" NPTF

NB use only fittings and tubing, suitable for the

maximum pressure performance of the pump.

Once the above instructions have been

completed the Power Pack is ready for use and

the following operating procedure can be

followed:-

Make sure the Isolator valve and

pressure let down valve is open and

the air pressure regulator is turned fully

anticlockwise. Direct the drain hose

into a suitable location as fluid will be

ATDP216,

discharged from this once the pump

starts.

Open the air on/off valve and turn the

regulator clockwise until the pump

starts to cycle. Increase the air pressure

until the pump is running at around 100

cycles per minute. Allow the pump to

cycle for approximately two minutes,

this will purge the pump of any air.

NB: This will not normally purge air from

the item under test. Additional vent

points (or other precautions) will be

required to ensure the item under test is

completely filled with liquid before

pressurisation otherwise a dangerous

situation may occur.

Stop the pump by closing the air on/off

valve. Should any black oil be visible

around the pump air motor exhaust,

this should not give rise to concern, as

lubricated air is fed to the pump, and

excess oil will be discarded via the

exhaust.

To apply hydraulic pressure:-

Close the pressure let down valve.

Make sure the isolation valve is open.

Turn the air pressure regulator valve

fully anticlockwise.

Open the air ON/OFF valve and

gradually increase air pressure by

turning the pressure-regulator

clockwise until the pump starts to

cycle. This will deliver liquid to the item

under test and (once all vent ports are

closed) allow hydraulic pressure to

build up. The pressure may build up

very slowly depending on the size of

the item under test. This pressure will be

indicated on the large pressure gauge.

The hydraulic output pressure is directly

proportional to the air inlet pressure.

The pump will stall when the hydraulic

pressure reaches a balance point

directly related to the air pressure

setting. To increase the hydraulic

pressure further, the air pressure must

be increased.

10. This feature can be used to maintain

pressure in a vessel over a period of

time. The pump will cycle occasionally

to keep the pressure topped up

against slight leakage loss.
