Feed Water Pumps

Grundfos Water Feed Pumps

Grundfos' unique feeding pumps for steam boilers offer unsurpassed efficiency in a variety of industrial processes. Each multistage pump is capable of feeding the boiler between 0.5 and 180 m3 water per hour, and the volume is easily increased by installing more pumps.

Designed to withstand the high pressure, the high media and ambient temperatures and the significant number of starts and stops encountered in boiler applications, the pumps have been optimised in every aspect – and are even capable of efficiently handling poor inlet conditions. The pumps can further be supplied with an air-cooled top that protects the shaft seal from any damage caused by high temperatures.

Grundfos CR1 Vertical Multistage Pumps

The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel and titanium. Thirteen flow sizes are capable of producing up to 180 m3/h at 50 bar, with a variety of shaft seals, rubber materials and supply voltages.

Grundfos optimise pump parts that are typically vulnerable to difficult liquids or demanding operating conditions.
