Meet Your Water Needs with CRI E Pumps
The CRI E pump is an in - line multistage pump with a built - in variable speed drive, suitable for various flow rates and pressures. Made of AISI 304 stainless steel, it is suitable for non - corrosive liquids. The built - in or external frequency converter of CRI E, along with the optional IE5 motor, makes it highly suitable for applications that require top - notch performance and control, as well as industry - leading energy efficiency. Use CRI E for liquid transportation, circulation, and boosting of cold or hot water.
MGE Motor Enhances Efficiency and Control
An IE5 MGE motor is available. It has the highest energy efficiency in the market and can adapt to continuously changing pump speeds, giving you full control.
Highest Standards
All parts in contact with the medium are made of AISI 304 stainless steel, suitable for various corrosive water environments, ensuring no corrosion.
Appropriate Solutions
The maximum - flow CRI E pump is the CRI E 20, with a flow rate of up to 29.6 m³/h and a pressure of up to 25 bar.
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 E 20 - 6 V - 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. According to the IEC 60034 - 30 - 2 standard, the energy efficiency of this motor is at the IE5 level. The motor terminal box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the pump to be optimized for operating conditions. The operation panel on the motor terminal box can not only set the pump to "minimum" or "maximum" operating intensity or "stop", but also set the required fixed value. The Grundfos Eye indicator light on the operation panel can show the status of the pump:
- "Power - on": The motor is running (rotating green indicator light) or not running (steady - on green indicator light).
- "Warning": The motor is still running (rotating yellow indicator light) or has stopped (steady - on yellow indicator light).
- "Alarm": The motor has stopped (flashing red indicator light).
Communication with the pump can be carried out through Grundfos GO Remote (accessory). The remote control can be used for further settings and reading of certain parameters, such as "actual value", "speed", "input power" and "total power consumption". The terminal box has a large number of input and output interfaces, enabling the motor to be used in advanced applications that require more inputs and outputs.
