MS Progressive Cavity Pump Range

The Mono MS range of pumps feature a compact design thanks to a single rotor, universal drive coupling. They’re also robustly constructed to ensure reliable operation and a long service life. These are progressive cavity type pumps which means that there’s a moving part, the rotor, within a fixed chamber, the stator. When the rotor turns a progressive cavity is formed which draws the liquid towards the discharge end of the pump.

The MS spins at 1,450 RPM and has a capacity of up to 165 gallons (750 litres) per hour at zero bar pressure. This combined with smooth action and quiet running thanks to a rubber stator make for a quiet running pump that’s ideal for domestic applications such as cellar drainage and garden sprinkler systems.

The MS is suited to many other applications too including septic tank and cess pit emptying, water supply from wells, rivers or streams, as well as non-aggressive chemicals and diesel. It’s self priming and can suction lift up to 26 feet (8 metres) which means that the pump can be mounted in an accessible location that’s clear of the liquid level. The MS weighs only 15 kilos and its 0.18 Kw motor can use a standard single phase electricity supply or a three-phase if preferred.

Using the progressive cavity principle means that the MS can maintain a steady output pressure with a non-pulsing flow. The latter is especially important in applications such as pumping heating oil to burner nozzles and for other industrial processes.
