Heavy duty Build

Our SHL range is built specifically to deal with a variety of corrosive and arduous applications including chemical transfer and water treatment.

316 Stainless Steel

The SHL range is constructed from 316 stainless steel meaning the pump is particularly suitable for water treatment and food processing.

Choice of Materials

Other materials are also available including Duplex, Superduplex and Hastelloy.

Open/Closed/Vortex Impeller options

The open impeller and Vortex impeller are suitable for aggressive liquids with suspended solids and/or high viscosities. The vortex impeller option features a recessed impeller, meaning over 60% of the liquid does not come into contact with the impeller, minimising risk of clogging.


The unique modular design of the SHL range means a pump can be simply adapted to cater for new plant and process requirements, thus keeping overheads to a minimum.

ISO2858, EN25199 certified

The SHL range is ISO2858 and EN25199 certified ensuring the ease of replacing existing pumps.

Wide range of seals

The SHL range can be fitted with various seal configurations from simple mechanical, double back-to-back to exotic cartridge types. Our trained team of experienced pump engineers are on hand to advise the best pump type for your application.

Flexibility to design requirements

Crest offer a totally flexible design specification, meaning a pump can be totally built to your business’s specifications. There are different seal, motor or connection options for the SHL range to be customised to your requirements.

18 months warranty
