SINES - Grundfos CR multistage pump


GRUNDFOS CR 10


  • Category: Surface pumps

Max. lift: 295 m - Max. flow rate: 10 m³/h

Grundfos CR 10 pumps are vertical multistage centrifugal pumps. The in-line design enables the pump to be installed in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal plane and have the same pipe dimensions. Grundfos CR pumps come with various pump sizes and various numbers of stages to provide the flow and the pressure required.

Solar pumping systems for reliable Water Supply in Africa

The new generation of Grundfos CR pumps features a full range of sizes and limitless scope for combinations to suit your specific needs.

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.

A CR pump consists of two main components: the motor and the pump unit. The motor is a Grundfos motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a sleeve, a pump head and various other parts.

Grundfos CR pumps are vertical multistage centrifugal pumps. : A centrifugal pump has a stationary part and a rotating part. the rotating part is called the impeller. the impeller has a number of vanes which force the water to rotate and creates flow. The stationary part is called the pump housing, or pump bowl. the bowl also has a number of vanes called guide vanes. their function is to stop the water’s rotation and to convert the energy in the rotation to pressure.

The CR is renowned for its reliability. And rightly so. The CR design has all the durability that customers expect from a high-quality multistage pump – and then some. CR have unique features to ensure unsurpassed reliability: dry-running protection, a unique cartridge seal, and a fulltitanium variant.

CR, CRI and CRN pumps are fitted with a totally enclosed, fan-cooled, 2-pole Grundfos standard motor with principal dimensions to EN standards.
