Product information
The Pentax CM 45 is a compact, ultra-quiet Italian single-impeller centrifugal electric water pump designed for domestic, civil, and small agricultural applications. Built with a heavy-duty cast iron pump casing and motor bracket, it provides dependable strength for long-term daily water supply.
A major advantage of the CM series is its ability to maintain constant water pressure even when flow demand varies. Unlike noisy jet pumps, the single-impeller centrifugal layout runs smoothly and quietly, making it ideal for residential pressure boosting, tank transfer, and garden irrigation without disturbing your household.
Engineered to save energy, its 0.3 kW (0.45 HP) 2-pole induction motor outputs up to 70 L/min while using very little electricity. Complete with an AISI 416 stainless steel motor shaft end, Noryl® impeller, ceramic-graphite seal, and thermal overload protection on single-phase versions, the Pentax CM 45 is an affordable, energy-saving choice for your home.
