Grundfos CRE5 3 x 380-500V Vertical Multistage Variable Speed Pumps In Cast Iron
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:
- Impellers and intermediate chambers are made of Stainless steel DIN W.-Nr. EN 1.4301.
- Pump head and base are made of Cast iron.
- The shaft seal has assembly length according to EN 12756.
- Power transmission is via cast iron split coupling.
- Pipework connection is via Oval / Rp flanges.
The pump is fitted with an IEC-flanged single-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:
- Pump start/stop (potential-free contact),
- external remote setpoint setting via analog signal, 0 - 10 V, 0(4) - 20 mA,
- 10 V voltage supply for setpoint potentiometer, Imax = 5 mA,
- pressure sensor factory-fitted.
- input for forced control to MIN, MAX, External fault or Flowswitch (potential-free contact),
- potential-free fault signal relay with changeover contact,
- RS485 GENIbus.
