Multistage In-line Pump
CRI
Applications:
Vertical multistage centrifugal pump with the suction inlet and the discharge outlet at the same horizontal level. The material of the pump body in contact with the liquid is stainless steel (EN 1.4301)."
CRI Vertical Multistage Centrifugal Pump: High Flexibility and Multiple Application Scenarios
The CRI pump of Grundfos is a vertical multistage centrifugal pump, which has the ability to provide various flow rates and different pressure levels. Made of AISI 304-grade stainless steel, it is suitable for transporting water and other non-corrosive liquids. The CRI vertical multistage centrifugal pump can also be applied in multiple scenarios, such as liquid transportation, ethylene glycol transportation, circulation systems, boosting of cold and hot water, and transportation of slightly corrosive liquids. Thanks to the flexibility and adaptability of the CRI pump, it has become an ideal choice for various liquid transortation systems
Excellent Corrosion Resistance
All liquid - contacting components of CRI vertical multistage centrifugal pumps are made of AISI 304 stainless steel. This effectively protects the liquid - contacting parts from corrosion and oxidation. Besides being corrosion - resistant, it also features wear - resistance, high strength, and heat - resistance. It can maintain good performance in various environments, making the CRI pump more efficient and reliable in use. Even under harsh site conditions, it can still deliver outstanding performance.

Multifunctional Solutions
The special water pump for deep - well pumping is suitable for small - scale water supply systems, with a maximum pumping depth of up to 90 meters.
CRI 20 - 17 A - FGJ - A - E - HQQE
Vertical multistage centrifugal pump with the inlet and outlet on the same horizontal plane (inline). The material of the pump body in contact with the liquid is stainless steel. The cartridge shaft seal improves the reliability of the machine and the safety of operation, and simplifies maintenance. Electrical energy is transmitted through a split - type coupling. Pipe connections are made via a combined DIN - ANSI - JIS flange. An asynchronous motor with three phases, a cooling fan and feet is installed on the pump.
