Sealless Pumps

Leak-Free Pumping, Circulating, Metering and Transferring of your Liquids and Chemicals

Michael Smith Engineers Ltd have specialised in supplying leak-free sealless pumps to the UK market since 1971.  Our range of leak-free pumps includes peristaltic pumps, diaphragm pumps and magnet drive gear, vane, turbine and centrifugal pumps.

Being leak-free by design, our sealless pumps are ideal for handling aggressive, corrosive and hazardous liquids.  We can pump a wide range of viscosities at high and low temperatures at capacities from ml/hr to m3/min and discharge pressures up to 170 bar.

If you need a leak-free pump that needs to be self priming or may on occasion run dry or that can handle solids then contact us with your enquiry and we will help select the right sealless pump for your application.
