Hydro Solo-E CRE 1-19 HQQE

Grundfos Hydro Solo-E booster set with one pump is a combined unit consisting of one E-pump (CRE) fitted with isolating valve, non-return valve, discharge pipe, pressure transmitter, pressure gauge and diaphragm tank. Upon delivery the booster set is ready for operation.

The pump has the following characteristics: - Impellers and intermediate chambers are made of Нержавеющая сталь DIN W.-Nr. DIN W.-Nr. 1.4301. - Pump head and base are made of Чугун. - The shaft seal has assembly length according to DIN 24960. - Power transmission is via cast iron split coupling.

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.

External sensor can be connected if controlled pump operation based on for example flow, differential pressure or temperature is required.

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, reporting Fault, Operation or Ready, - RS485 GENIbus.
