Design of CL pumps
The CL type inline flow centrifugal vortex pumps are single-stage devices with compact design and a layout of connectors that enables direct coupling with central heating of hot domestic water pipelines. The pump is installed directly on a motor with a special shaft end that accommodates the pump rotor and a mechanical face seal. The pump body is bolted via a special adapter to the motor flange with M8 (CL3) or M10 (CL4) stud bolts.
