VSL Plastic Vertical Sealless Pump

The VSL plastic vertical seal less pump range are proven to stand the test of time offering solid performance constantly throughout the pump’s lifetime, minimising both operational costs and maintenance costs whilst keeping your process running efficiently and reliably.

The VSL range of non-metallic vertical sealless pumps are able to run-dry indefinitely due to the pumps cantilever design without immersed bearings. They also feature a double balanced impeller, which creates a liquid ring seal preventing the liquid from backing up the pump shaft.

Every plastic vertical pump in our range is designed and manufactured in the UK so we can tailor the pump to your exact requirements – whether that be a particular column length, mounting plate shape or outlet position. Usually with very little difference in price of lead time compared to a standard pump.

The vertical range are suitable for all types of applications, including metal treatment, tank emptying, transfer and re-circulation, effluent treatment amongst many other corrosive duties and may be mounted internally or externally enabling valuable tank space to be fully utilised.

All VSL pumps feature a standard 400mm column length. Suction extensions, non-return valves, strainers and level control switches are all readily available as optional extras.
