Designed and manufactured in the UK with the simplicity of 5 models sharing as many common components as possible, it enables quicker lead times and even more competitive pricing. All Surge pumps feature a standard column length of 400mm and are offered with optional extras including suction extensions, non-return valves, strainers and level control switches which are all readily available. Capacity 57 M³/Hr ![image00011](https://www.crestpumps.co.uk/hs-fs/hubfs/Vertical%20Immersible/image00011.jpeg?width=300&name=image00011.jpeg) Head 38M SOLIDS PUMPING CAPABILITIES HEAVY DUTY CANTILEVER SHAFT COLUMN LENGTH 400MM POLYPROPYLENE/PVDF BUILD [Download Our Datasheet](https://www.crestpumps.co.uk/hubfs/Surge%20Datasheet.pdf) #### MINIMAL MAINTENANCE The Surge range of vertical plastic pumps are able to run-dry indefinitely due to the pump’s 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. #### RUGGED DESIGN All wetted parts are fabricated or machined from solid thermoplastic ensuring a very rugged and reliable pump. We offer two durable material options: Polypropylene and PVDF plus a choice of O-ring materials providing the ultimate corrosion resistance for your application. The Surge vertical pumps may be mounted internally or externally to the tank enabling valuable tank space to be fully utilised. #### SUITABLE FOR ALL APPLICATIONS The Surge range are suitable for all types of applications, including metal treatment, tank emptying, transfer and re-circulation amonst many other corrosive duties. All Surge pumps feature a standard column length of 400mm and are offered with optional extras including suction extensions, non-return valves, strainers and level control switches which are all readily available.  ![chemical_plant_tint_optimized_950](https://www.crestpumps.co.uk/hs-fs/hubfs/chemical_plant_tint_optimized_950.jpg?width=300&name=chemical_plant_tint_optimized_950.jpg) ## THE CREST PUMPS LIFETIME GUARANTEE **No matter how old your pump becomes, in the unlikely scenario that you have a problem, our engineers will be on hand to diagnose the issue and help you get up and running again.

How does a vertical immersible pump work?** A vertical immersible pump operates with its pump end submerged in the fluid while the motor remains above the liquid level. The pump uses an impeller to draw fluid up through the pump column and discharge it at the surface. This design prevents motor exposure to harsh fluids, making it ideal for handling corrosive, abrasive, or high-temperature liquids in industries like chemical processing and wastewater treatment. What Are the Advantages of Using a Vertical Immersible Pump?** Vertical immersible pumps offer several benefits, including space-saving design, as they require a smaller footprint than horizontal pumps. They prevent motor exposure to corrosive or hazardous fluids by keeping the motor above the liquid level. These pumps also provide high efficiency and reliability, with minimal risk of leaks due to their seal-less or semi-sealed designs. Additionally, they are easy to maintain, as the motor and key components remain accessible without needing to drain the tank or sump ## Trusted By The Best ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Galvanizing-3](https://www.crestpumps.co.uk/hs-fs/hubfs/Galvanizing-3.jpg?width=300&name=Galvanizing-3.jpg) ## DON’T JUST TAKE OUR WORD FOR IT *I have found Crest to be an honest, straight forward company to do business with.
