Vertical multi-stage centrifugal pump with the suction port and the discharge port located on the same horizontal plane. The pump head and the base are made of cast iron, and all other wetted parts are made of stainless steel (EN 1.4301).
CR Vertical Multi-stage Centrifugal Pump: High Efficiency and Reliability
The CR vertical multi-stage centrifugal pump is a centrifugal water pump suitable for non-corrosive liquids. It is manufactured from cast iron, and all liquid-contacting components are made of AISI 304 stainless steel. This pump can achieve a flow rate of up to 320 m³/h and an operating pressure of 40 bar. It is highly suitable for various applications such as the transportation, circulation, and pressure boosting of cold and hot water, as well as for agricultural and farmland irrigation.
The reason why the CR multi-stage centrifugal pump is reliable is that strict control of every aspect of the production process is crucial. It complies with the strictest international standards and has obtained the ISO 9001 certification, and is subject to strict process control. Each CR vertical multi-stage centrifugal pump undergoes performance, power consumption, and static pressure tests before leaving the factory.
According to the location, the degree of danger, and the likelihood of dangerous situations occurring, we can provide a variety of CRN multi-stage centrifugal pumps approved by ATEX. These ATEX-approved pumps are suitable for potentially explosive environments.

CR 255 - 6 - 2 A - F - A - E - HQQE Vertical multi - stage centrifugal pump with the inlet and outlet on the same horizontal plane (in - line). The pump head and the base are made of cast iron, while all other components in contact with the liquid are made of stainless steel. The built - in thrust control device can absorb the hydraulic axial force, so a standard motor can be used. The Grundfos cartridge shaft seal can improve the reliability of the machine and the safety of operation, making maintenance easier. Electrical energy is transmitted through a split - coupling. The connection of the pipeline is achieved through DIN flanges. An asynchronous motor with a cooling fan and a foot - mount, in three - phase, is installed on the pump.
