Torishima - Model CPW Series - Hot Water Circulating Pumps - Brochure

The CPW pump series are used mainly as feed pumps or circulating pumps in high pressure hot water generating plants. CPW hot water circulating pumps represent a complement to existing series of single entry and single stage pumps of process type construction. The casing can remain connected with the piping when the rotor is dismantled. If a spacer-type flexible coupling is fitted, the driving motor can also remain set on the baseplate, and the timewasting re-alignment of pump and motor after reassembly of the pumping set can be dispensed with. The well-proven module construction system already adopted on several pump series has again been adopted for the CPW series. The 18 available pump sizes offer economic operating conditions at the duty point and favourable NPSH values over the entire performance range.
