Heavy Duty Self-Priming Side-Channel Pumps Type SC

General The DICKOW-pump, type SC, is a self-priming horizontal side-channel pump. The side-channel pump with its high differential head – also at low speed – has the advantage of operating more economical than normal centrifugal pumps for low capacities and high heads. Due to these facts, the side-channel pumps are appropriate to solve many pumping problems in chemical and petrochemical industries. The SC-pump is a heavy duty pump for handling clean liquids without solids. SC-pumps are also able to prime empty suction lines after initial filling with liquid before start-up. The maximum allowable...

monitoring can protect the pump against dry running in this case. Due to the tight clearances between the sidechannel impellers and the stage disks, the standard design of these pumps will not tolerate any dry running. Liquid level monitoring in the suction line at flooded conditions is recommended. For self-priming conditions with suction lift, an optoelectronic level detector can be fitted in the diffuser to monitor the required liquid level in the pump. The design with additional SiC-rings can also accept dry running for a limited time. Motor load Hazardous area Together with the required...
