Always operate the system under no load
condition prior to the actual lift to ensure that
no air is trapped in the hydraulic circuit.
Do not drop or place heavy objects on a
hydraulic hose as this will cause internal
damage to the hose which could result in
rupture when the hose is pressurized and could
result in serious damage to components, and
possible serious personal injury to operating
personnel.
3.0 Description AHP series Air Driven Pumps.
The device supplied is an air-powered
hydraulic pump that converts a compressed air
supply into a pressurized hydraulic flow (see
"Technical specifications" – table below Fig 2).
The pump can be utilized to power single and
double acting hydraulic cylinders; in the latter
case a directional control valve between
pump and cylinder is required. The filler/
breather plug can be removed and used as a
return line. (or select model AHP 1141/ 1142).
Any other uses of the pump shall be considered
improper and can cause serious accidents. The
manufacturer declines all liability for damages
resulting from improper use of the pump.
The main components of the pump
Note: Models ending with "R" (AHP1120R/
1121R/ 1122R) are operated with a hand
pendant instead of a treadle (Fig 16).
