ATDP SERIES – Hydrotest Pumps:
1.0 General Description
The Hi-Force ADTP range of Hydrotest pumps
are supplied in a range of 3 models with output
pressures ranging from 87 bar(1260psi) to
1489bar (21600psi) and are suitable for use with
various fluids.
The ADTP air driven liquid pump range work on
an automatic reciprocating differential area
piston principle that uses large area air drive
pistons connected to smaller area hydraulic
pistons to convert compressed air power into
hydraulic power.
The ADTP pump range has a double acting
motion incorporating two hydraulic cylinder and

piston assemblies, as liquid is introduced into one
hydraulic cylinder on the pump suction stroke,
liquid is automatically delivered from the
second high pressure cylinder at the same time
on the pump delivery stroke and vice versa.
When the pump reaches the end of its stroke the

direction; hence delivery flow is relatively
smooth with only a small interruption in flow
(dwell) as the pump air pistons change
direction.
The units consist of a robust framework painted
to Hi-Force standard colour, fitted with an air
driven hydraulic pump and complete with all
necessary hydraulic accessories i.e. a 150mm
diameter hydraulic pressure gauge, a hydraulic
pressure release valve and all interconnecting
pipe-work fittings and adaptors, terminating at
a single high pressure outlet connection port.
Pneumatic accessories include an air filter, air
pressure regulating valve, oil lubricator, air
gauge and air on/off valve.
A fluid inlet connection is provided and a Y
type fluid strainer and fluid relief valve set at
approximately 10 bar is fitted between this
connection and the pump inlet check valves.
Provision is provided for fluid drainage via a
nylon hose connected to the hydraulic pressure
release valve.
The ATDP63 has a maximum recommended
working pressure of 434Bar (6,295psi) on the
hydraulic pressure circuit.
The hydraulic pressure to be generated by the
air driven pump is dependent upon the air
pressure applied i.e.
Pump ratio 63/1: 1psig air drive pressure
applied can generate 63psig hydraulic
pressure.
The ATDP125 has a maximum recommended
working pressure of 862Bar (12502psi) on the
hydraulic pressure circuit.
The hydraulic pressure to be generated by the
air driven pump is dependent upon the air
pressure applied i.e.
Pump ratio 125/1: 1psig air drive pressure
applied can generate 125psig hydraulic
pressure.
The ATDP216 has a maximum recommended
working pressure of 1489Bar (21596psi) on the
hydraulic pressure circuit.
