Applications:

A large volume centrifugal pump, to which a pre-filter has been applied in the inlet, making these the ideal pumps for large filtering units. The fact that the pump works with a 1,450 rpm. motor makes it very quiet and long lasting.

Constructive characteristics:

Pump body, support, pre-filter and impeller in cast iron. Shaft-coupling and pre-filter sieve in AISI 316 stainless steel. Mechanical seal in carbon – silicium carbide. On demand the HF-4 pump range may be supplied with bronze impeller (standard in cast iron) or with other versions of mechanical seal, such as : tungsten carbon, aisi 316, epdm, viton etc.

Motor:

Standard asynchronous motor, sealed from external ventilation. Its standard construction allows it to be replaced with another standard motor at any time and in any place. Protection IP-55. 1,450 rpm. 50-60 Hz.
