Grundfos CRNE10-09-J-CA Centrifugal pump

• Boosting water pressure in industrial and commercial buildings.
• Circulating liquids in heating and cooling systems.
• Transferring process water and other non-corrosive liquids in manufacturing.
• Supplying water for irrigation and agricultural applications.
• Handling clean-in-place (CIP) solutions in food and beverage processing.

Pump Type

Vertical multistage centrifugal pump, commonly used for high-pressure applications.

Motor Power

This unit is specified at 7.5 kW; for this class, motors typically range from 1.1 kW to 22 kW or more.

Inlet/Outlet Diameter

This unit has 50mm connections; commonly found sizes for this type of pump range from 32mm to 100mm.
