6.0 General Description

Hi Force ATDP Hydrotest pumps are designed to have an infinately variable output pressure and

displacement speed. They are fitted with an integral filtration and lubrication unit and air pressure

gauge. An airline regultor allows for easy setting of air inlet pressure and output hydraulic

pressure. The air start/stop valve allows for easy and fast pressure shut off. An air relief valve

(ARV) is fitted to the air inlet. The ARV is factory set to allow maximum pressure to be achieved

and vent any overpressurisation to the atmosphere.

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 (21596psi) and are suitable for use with

various fluids. See 1.0 Specifications.

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 spool

valve in the air change over valve motor automatically shifts, reversing the pump 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, 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, ARV 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 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 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 working pressure of 1489Bar (21596psi) on the hydraulic

pressure circuit. The hydraulic pressure to be generated by the air driven pump is dependent
