Multistage, non-self-priming, horizontal high-pressure centrifugal pump in block design with horizontal suction port and vertical pressure port and built-in, air-cooled frequency converter. The integrated frequency converter enables variable speed control.
- Mode 1: Manual speed control via pump potentiometer
- Mode 2: Pressure control via 4-20mA or 0-10V pressure sensor signal – set point adjustment with pump potentiometer
- Mode 3: Speed control via external 0-20 mA or 0-10V signal
Short-circuit-proof +24 V voltage output with max. contact strength of 30 mA present on the electronic module. The module has potential-free contacts for SSM, red and green LED for ON/OFF signal.
This pump has a compact design with a continuous motor pump shaft and a bidirectional mechanical seal.
The pump is suitable for water supply and pressure boosting, industrial recirculation systems, process water and cooling water circuits. It can also be used in fire extinguishing systems, washing systems as well as for irrigation.
