Product Description

AM Plastic Magnetic Drive Pump

Magnetically driven pumps, such as the AM Plastic Magnetic Drive Pump, are the industry standard when processing harsh and highly corrosive applications. The centrifugal force is driven by two rotating magnets rather than being directly coupled to a motor, which eliminates the need for a mechanical seal, making the magnetic drive close coupled pump completely leak proof.

Your Process Covered

To minimise any disruption to your process, both the polypropylene and ETFE constructed close coupled pump are available ex-stock. With specialised material, including ceramic and silicon carbide, we can guarantee a chemical resistant pump for any of your corrosive applications. For further peace of mind, we offer 2 years warranty as standard with all magnetic drive pumps. We even offer a 5 year extended warranty as an optional extra as an assurance that Crest have got your process covered.

Minimal Maintenance

Downtime is reduced and production increased thanks to the compact design that requires very little maintenance over its lifetime. Servicing and maintenance is handled quickly thanks to the minimal parts used in the design build. All parts and complete pumps are available ex-stock.

High Efficiency Design

The geometry of the impeller and casing are generated through hydraulic design programmes. Whilst taking into account the fluid dynamics, hydraulic loss is minimised and pump efficiency maximised. Our pumps are trusted by global chemical companies across the globe, including GlaxoSmithKline, ConocoPhillips and Smurfit Kappa.

All Crest Pumps are suitable for applications across the globe. Please contact us with your location and motor requirements. We can then supply performance curves relative to your required speed and voltage.
