Our pumps were studied and manufactured to bring you complete satisfaction. They were designed with the finest quality materials, produced according to modern processes, and controlled by strict tests.

Our basic catalogue includes versions of our series 0 to 5 pumps according to European and American Standards (SAE).

Keep in mind, the working cycles described are possible with hydraulic mineral oil for viscosities between 12 and 150 cSt (65.2 and 700 SUS). Additionally, the pump can only run in one way rotation (Specify the direction of rotation upon your order). The minimum viscosity of 12 cSt (65.2 SUS) is available for a maximum temperature in the hydraulic circuit as well.

Working temperature: -20 °C ( 4 °F ) to +80 °C ( 176 °F ) ||  140 °C ( 284 °F ) with Viton shaft seal 

Full flow filtration: 10 to 15 microns at the pressure port of the pump or on the return circuit

Filtration on the suction side: 125 microns

Pressure at the inlet of the pump
Minimum 0.7 bar absolute ( Maximum depressure is 300 millibar with regard to the air pressure ) 
Maximum 2 bar absolute or 1 bar over the air pressure .

The hereabove characteristics concern pumps driven by elastic couplings that are perfectly aligned without any external radial or axial force. For any other coupling, see technical data sheet F.T R 0009 (Recommendation concerning the drive type of HPI Hydraulic Pumps).
Finally, for use in maximum working conditions and/or intensive cycles, consult our technical sales service for validation.
