Thermoplastic Magnetic Drive Pumps

Magnetically driven pumps 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. This eliminates the need for a mechanical seal and therefore making magnetic drive pumps sealless and leak proof.

YOUR PROCESS COVERED

To minimise any disruption to your process, both polypropylene and ETFE constructed pumps 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.

Frequently Asked Questions

What are magnetic drive pumps used for?

Magnetic drive pumps are used in a wide variety of applications, including chemical processing, water treatment, and metal finishing. They are designed to provide a reliable and efficient solution for transferring corrosive and hazardous liquids. The pumps are constructed with a non-metallic construction, making them ideal for use in highly corrosive and hazardous environments.
How do magnetic drive pumps work?

Magnetic drive pumps are centrifugal pumps that use a magnetic coupling to transmit power from the motor to the impeller. The drive magnet is mounted on the motor shaft that will connect by magnetic force to driven magnets contained within the pump. This type of pump is ideal for applications where leakage or contamination of the pumped fluid is a concern, as there is no mechanical seal or shaft seal to fail.
Which chemicals are your pumps suitable for?

We have specialised in corrosion resistant pumps since 1973 so can almost certainly find you a solution to your application. Our chemical resistance table shows just some of the liquids we have experience pumping, but please talk to us to find the best chemical pumping solution for you.
Best practices for maintaining a magnetic drive pump?
  • Check the pump regularly for signs of wear and tear.
  • Ensure the pump is properly lubricated.
  • Check the bearings for any signs of wear or damage.
  • Ensure that the pump is properly aligned with the drive motor.
  • Check the temperature of the pump and ensure it does not exceed the recommended levels.
  • Ensure that the pump is running at the correct speed. 
Are these pumps fully corrosion and acid resistant?
Our range of magnetically driven acid pumps are fully corrosion and acid resistant against harsh applications such as Sulphuric Acid or Hydrochloric Acid.
We offer a range of durable and robust materials to tailor the pump to your exact businesses specifications and needs. Such as PVDF, Polypropylene, ETFE, PTFE, PVC and 316 Stainless Steel for the front and rear housing. Using the correct and most robust materials Reduce downtime and maintenance costs to your business.
For rare acid applications, we can also provide specialist O-ring materials and ceramic front and read rings.
