Marine Hot Water Circulating Pump

CISR Marine Hot Water Circulating Pump for Ship Domestic Water Systems

Product Overview
The CISR-type single-stage marine hot water circulating centrifugal pump is engineered for reliable performance in vessel hot water supply and marine boiler applications. Designed to the same installation dimensions and performance standards as the IS single-stage single-suction centrifugal pump, this unit efficiently handles hot fluids up to 200°C. It is an ideal solution for marine domestic water circulation, heating systems, and high-temperature freshwater transfer.

Supplies freshly generated potable water from marine evaporators
Delivers heated water to accommodation blocks via hydrophore tank pressure
Circulates hot water efficiently using dedicated marine circulating pumps
Supports sterilization systems for safe drinking water
Provides essential water supply for HFO, DO, and LO separators
