Grundfos CRNE 125-1 In-line Multistage Pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in high-grade stainless steel. The Grundfos 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”.
