ATDP – Air driven, twin, double acting hydrotest pumps This manual applies to the Hi-Force ATDP series of air driven hydrotest pumps only. It contains the latest product information available at the time of publication and approval. For information relating to the servicing of an ATDP pump, see the servicing instructions, which are available on the Hi-Force website.
Temperature range Degrees Celcius ISO Hydraulic oil grade From: ISO15 ISO46 IMPORTANT: If in doubt about the suitability of the operating fluid you intend to use, please consult your nearest Hi-Force office or distributor. Use of unsuitable operating fluids WILL void your warranty.
If in doubt on the correct use of any Hi-Force equipment, contact your nearest Hi-Force office or distributor. Only qualified personnel should be allowed to operate hydraulic equipment. If an operator has not been trained on high-pressure hydraulic equipment and its safe usage, consult your local Hi-Force sales office or distributor who can offer training courses for operators.
Operating Instruction Manual: From Serial Number: OM-ATDP-01 4.2 Work Area Safety • Keep work areas clean and well lit. Cluttered spaces and inadequate lighting can result in unnecessary accidents. • Keep bystanders clear of any hydraulic tool activity. Personnel working in close-range should be made aware of all high-pressure work before commencing.

NEVER attempt to solve, or clean-up leaks in the system while the system is pressurised. • Immediately replace any worn or damaged parts using genuine Hi-Force parts only. • DO NOT use any hydraulic equipment if you are under the influence of alcohol, drugs or medication.
1489bar (21,596 psi). See Specifications • DO NOT adjust or remove the external pressure/air relief valve (ARV) on any Hi-Force product. • NEVER invert the unit or lay it on its side, either in use, in transport or in storage.
(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.
Operating Instruction Manual: From Serial Number: OM-ATDP-01 upon the air pressure applied i.e. Pump ratio 216/1: 1psig air drive pressure applied can generate 216psig hydraulic pressure. 7.0 Component Identification...
Operating Instruction Manual: From Serial Number: OM-ATDP-01 8.0 Installation / Setup 8.1 Before First Use / Preparation It is recommended to use good quality clean & dry air (without moisture content) to drive the air driven pump unit. As the air pressure drops at the pump exhaust ports, the air will cool and any water droplets in the air can freeze prematurely due to temperature variation.
The maximum pressure achievable at various air pressures can be seen in the Hi-Force catalogue ATDP page under the heading “Max output pressure at airline input pressure” e.g. ATDP63 if 80 psi air pressure is applied then the maximum pressure the pump can generate is approximately 80psi x the pump ratio 63/1 = 5,040psi (347bar).
Operating Instruction Manual: From Serial Number: OM-ATDP-01 • If the air supply is turned to the OFF position the hydraulic pressure generated will hold on the pumps integral check valves (in small volume systems the hydraulic pressure may fall slightly and then stop whilst the check valve balls reseat, this is normal).
