Grundfos CRE32: 3 x 380-500V Vertical Multistage Speed Pumps In Cast Iron (304 Stainless Steel Wetted Components)
Product Description
Vertical, non-self-priming, multistage, in-line, centrifugal pump for installation in pipe systems and mounting on a foundation.
The pump has the following characteristics:
|
The pump is fitted with an IEC-flanged three-phase MGE motor with frequency converter and PI-controller integrated in the motor terminal box. No additional motor protection is required as both motor and electronics are protected by integrated overload and temperature protection.
The pump is equipped with a pressure transmitter registering pump discharge pressure and enabling controlled pump operation based on constant pressure.
A control panel enables setting of required setpoint as well as setting of pump to MIN or MAX operation or to STOP. The control panel has indicator lights for "Operation" and "Fault".
Communication with the pump is possible by means of Grundfos R100 Remote Control enabling further settings as well as reading out of a number of parameters such as "Actual value", "Speed", "Power input" and total "Power consumption".
The terminal box holds terminals for the connection of:
