Priming Methods

CP offers both flooded suction and self-priming pumps.

Flooded suction pumps

Pumps are usually designed to pump liquids and consequently need to have a positive suction pressure. To start successfully, they must be completely flooded with the fluid to be pumped. These pumps are not capable of handling air, gases or vapours, even for a limited time, as there is a risk of the fluid flow being interrupted or the bearings damaged due to dry running when not solely pumping liquid. Today, pumps with flooded suction are CP's standard. This priming method is necessary in most pumping systems.

CP models: MKP, MKTP, MKPP, SZMK, MKP-Bio, MKPL, MSKP, MSKPP, IL-BTO, ZMP, EB, ET, KTP

Self-priming pumps

Self-priming pumps are able to handle large amounts of air, gases or vapours for a limited time while building up sufficient negative suction pressure, even if they have been designed to pump liquids. This means that such pumps can draw fluid from a supply located below the pump. The maximum self-priming height (geodetic suction lift) is limited by the achievable vacuum, local atmospheric pressure, fluid density and the flow resistance to be overcome.

CP models: MKP-S, MKPL-S, MSKS
