The device supplied is an air-powered hydraulic pump that converts a compressed air supply into a pressurized hydraulic fl ow (see
“Technical speci fi cations” Chapter 4).
The pump can be utilized to power single and double acting hydraulic actuators; in the latter case a directional control valve must be
interposed between pump and user.
THE USE OF THE PUMP IN POTENTIALLY EXPLOSIVE ENVIRONMENTS, IF NOT DULY PROTECTED (PRO-
TECTION NOT SUPPLIED) IS STRICTLY FORBIDDEN. POSSIBLE ACCUMULATION OF ELECTROSTATIC
CHARGES.
All other uses of the pump shall be considered improper and can cause serious accidents. The manufac-
turer declines all liability for damages resulting from improper use of the pump.
Ask the manufacturer if in doubt about the correct installation and use of the pump.
