Grundfos CRIE 3-17 N CA A E HQQE 2.20kW Vertical Multi-Stage Pump (with Sensor) 415V

The CRIE with sensor models have been designed for closed feedback loop variable speed control and are supplied with constant pressure transducers already fitted. The default control mode is ''constant pressure''.

The single point pressure transducer is fitted into the accessory port in the pump head.

The Grundfos CRE, CRIE and CRNE pumps are based on the CR, CRI and CRN pumps and are referred to as E-pumps.  The difference between the CR and CRE pump ranges is the motor. CRE, CRIE and CRNE pumps are fitted with a motor with built-in frequency converter.

The E-pump MGE motor is designed to EN standards.  The built-in frequency converter enables continuously variable control of the motor speed. This means that the pump can be set to operation at any duty point.  The purpose of continuously variable speed control of the motor speed is to adjust the performance to a given requirement.  These pumps are available with an integrated pressure sensor connected to the frequency converter.  The pump materials are identical to those of the CRI and CRN pump ranges.

Select an E-pump if the following is required:

• controlled operation, i.e. the consumption fluctuates
• constant pressure
• communication with the pump

Adaptation of performance through frequency controlled speed control offers obvious benefits, such as:

• energy savings
• increased comfort
• control and monitoring of the pump performance

CRIE pumps fitted with A CA I E HQQE seal codes are supplied with no pipe connection and require a set of 2 x 2 bolt oval flanges.  Pumps fitted with FGJ and F flanges require counter flanges.

The "E" pump range requires a Grundfos "GO" communication device in order to commission the pump.  This device can be used to commission and monitor multiple pumps on multiple sites.
