SIHI high temperature



SIHI high temperature pumps are single stage end suction pumps that can transfer hot water up to 230°C and hot oil up to 350°C.

They have a back pull out design which permits the removal of the complete bearing housing and frame without removing the pump casing from the pipework. 

Also available long coupled on a base frame with electric motor.

Product Information

Hot water pumps Hot oil pumps

Hot water pumps from SIHI are primarily used for circulation of hot water in closed pipe and vessel systems.  Therefore their fields of application are the energy production industry, the heat transport industry, and in other systems where hot water as the heat carrier is preferred, rather than oil.
