Mono CP25 Progressing Cavity Pump 240v - Designed for use where low flow or transfer duties in both domestic and industrial applications are required these units are self priming and achieve suction lifts up to 8 metres on water. Mono's CP Range pumps provide an economic answer to many pumping duties. Simple design and construction provide extended pump life with minimal routine servicing. The progressing cavity pump principle is ideal for handling slurries viscous shear sensitive or two or tri phase mixtures or when applications require significant suction lift capabilities. The heart of the Mono pump is the rotor and stator. As the single helix rotor revolves eccentrically within the double helix of the stator a continuous cavity is formed and progresses towards the discharge end of the pump as the rotor rotates.
