|How does it work?
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.
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 - silicon carbide. On demand the CF-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...
These pumps are easy and simple to maintain, as the construction of the pump, which includes a totally standard motor allows the motor to be changed or repaired without emptying the installation, even when you do not have pump inlet and outlet valves, or removing any part from the hydraulic part of the pump.
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.
