Product Information
DURAPAC – Two Speed Air Hydraulic Pumps are engineered to meet Industrial Standards for
Performance and Safety. They are ideally suited to applications where air is the preferred power
source. The pumps feature a Gast® heavy duty air motor with an ON/OFF air supply sleeve and an
11 litre usable oil reservoir. They have a 3 way/3 position valve for Advance/Hold/Retract of a single
acting cylinder/tool and the valve handle operation can be swapped from detent to spring loaded.
The unique hydraulic circuit allows the quick displacement of hydraulic fluid under no load
conditions and easy pumping in loaded conditions. These air actuated pumps supply compressed
hydraulic fluid to a compatible single-acting cylinder, anywhere that 700 bar (10,000 psi) of fluid
pressure is needed.
Special skill, knowledge and training may be required for a specific task and the product may not be
suitable for all jobs. The user must ultimately make the decision regarding suitability of the product
for any given task and assume the responsibility of safety for all in the work area. Contact a Durapac
representative if you are unsure of your pump’s suitability for a particular application.

rated working pressure of each pressurised attachment be equal to or greater than the rated
working pressure developed by the hydraulic pump
