Vane Pumps Provide Smooth, Leak-Free Pumping

Pump specialists Michael Smith Engineers, U.K., has recently added a new range of magnetically coupled vane pumps to the pumps and pumping systems it offers. The M Pumps series of vane pumps provide the important benefits of sealless, safe leak-free pumping and are available in plastic (polypropylene and PVDF) and stainless steel wet end construction. They also offer stainless steel multistage configurations for higher differential pressure applications.

In addition to their sealless, mag-drive design, M Pumps’ three series of vane pumps are noted for their smooth, pulse-less, constantly accurate output, along with their ability to handle thin liquids at relatively high pressures. They are self-priming and some models can run dry for short periods. They are also able to compensate for wear through vane extension and have good suction lift capabilities. All M Pumps are designed for close-coupling to the motor, which minimizes the space footprint needed.

The pump illustrated (photo) is a new design that features a polypropylene pump head housed in a steel casing and is capable of withstanding system pressures up to 15 bar. It is designed for pumping water at six liters per min. at a differential head of 17 meters. This pump provides the assurance of no leakage thanks to its magnet coupling, smooth, pulse-less flows, and the capability to withstand high system pressures.

In terms of overall performance for the three series of pumps, the plastic pumps are capable of capacities up to 3,000 liters per hour, discharge pressures to 6 bar, and viscosities up to 10,000 cP. The stainless steel versions have similar output and viscosity handling capacities, but higher discharge pressures to 14 bar, while the multistage versions provide capacities up to 3,000 liters per hr., discharge pressures to 25 bar, and viscosities to 10,000 cP.
