New Grundfos Vertical, multistage centri CRE 64-3-2 A-F-A-E-HQQE

New Grundfos Pump - Vertical, multistage centrifugal pump with integrated frequency converter. inlet and outlet ports on same the level (inline). The pump head and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe
handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via DIN
flanges.

The pump is fitted with a 3-phase, fan-cooled asynchronous motor. The motor includes a frequency converter and PI
controller in the motor terminal box. This enables continuously variable control of the motor speed, which again
enables adaptation of the performance to a given requirement. An operating panel on the motor terminal box enables
setting of required setpoint as well as setting of pump to "Min." or "Max." operation or to "Stop". The operating panel
has indicator lights for "Operation" and "Fault".
Communication with the pump is possible by means of Grundfos GO Remote (accessory). The remote control
enables 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 these connections:
• pump start/stop input (potential-free contact)
• remote setpoint setting via analog signal, 0-10 V, 0(4)-20 mA
• 10 V voltage supply for setpoint potentiometer, Imax = 5 mA
• three analog sensor inputs, 0-10 V, 0(4)-20 mA
• 24 V voltage supply for sensor, Imax = 40 mA
• one analog output
• three digital inputs
• two Pt100 inputs
• two potential-free fault signal relays with changeover contact, reporting "Fault", "Operation" or "Ready"
• RS-485 GENIbus connection
• interface for Grundfos CIM fieldbus module
