The VSL range of Vertical Plastic  Pumps are built specifically for corrosive applications that include, but not limited to, metal treatment, tank circulation and effluent treatment. VSL Vertical Plastic Pumps provide a cost effective and efficient solution to any corrosive application.

The design of the VSL pump allows a double impeller to be fitted, meaning no mechanical seal and therefore no risk of running dry. A polypropylene thrower protects the motor bearings from harmful and corrosive fumes.

The wetted parts are fully corrosion resistant and are available in Polypropylene, PVC, PVDF or 316 stainless steel.

VSL pumps can be mounted either internally or externally in order to maximise the tank space, especially for applications where tank space is limited.

All VSL pumps come in a standard 400 mm column length. Suction extensions, non-return valves, strainers and level control switches are all readily available as optional extras. Complete packages, including sump tanks, can be supplied to meet your specific requirements.

Max Capacity Rate: 80m³/hr (1333 l/m) Max Discharge Head: 40 meters Manufactured in our UK Plant

Choice of Materials

The VSL range of Vertical Plastic Pumps are available in a range of materials, including Polypropylene, PVC, PVDF or 316 stainless steel.

Run-Dry design

Running dry is one of the biggest causes of failure to pumps in the industry. With Crest’s Vertical Chemical Pumps, the unique run-dry design will stop the pump failing when there is a problem in the production line, meaning less down time for your business and a more cost effective solution.

Double balanced impeller

The VSL range features a double balanced impeller, meaning the pump is seal-less and therefore leak free.

Short lead times

The VSL range of Vertical Plastic Pumps are available with an extremely quick turnaround time.

Minimal maintenance

Because the pump is able to run-dry, the pump requires minimal maintenance.

18 Months warranty

With our Vertical Chemical Pumps, we offer as standard, 18 month warranty as an assurance to your business that the pump is quality built.

Flexible to design requirements

Crest offer a totally flexible design specification, meaning a pump can be totally built to our business design requirements, i.e. certain sized piping in your existing system.
