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 4 poles 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 instal-lation, 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 exter-nal ventilation. Its standard construction allows it to be replaced with another standard motor at any time and in any place. Protection IP-55. 4 poles 50-60 Hz.
