Patented Run-Dry Design

Running dry is one of the biggest causes of failures to pumps. With Crest’s Mag Drive range, the Ppatented Run-dry design will stop the pump failing if there is a problem, meaning less down time for your process and as a result, less time and money lost to your business.

High Efficiency

The AMX Mag Drive range is one of the most efficient pump designs Crest offers; up to 70% operating efficiency, reducing operating costs and energy consumption for your business. By reducing energy consumption this pump is good news for reducing your operating costs as well as making the pump more eco-friendly.

Unique Buffer System

The AMX Mag Drive range offers a unique buffer system, designed to absorb vibrations and shock caused by adverse operating conditions. At the same time, the dynamic buffer is self-adjusting, allowing a better face to face contact between the thrust ring and the wear ring, minimizing wear and increasing service life.

Choice of Materials

The AMX range comes in a choice of corrosion resistant Polypropylene, PVDF or ETFE to increase the pump life and increase time in-between pump servicing. The new AMX design now has a polypropylene bracket and baseplate as standard for  greater chemical resistance in corrosive environments.

Leak-Free Design

Using the static sealing, instead of the traditional dynamic mechanical seal completely solves the problem of leakage, avoiding unnecessary clean up bills saving money and avoiding ecological damage.

Ex-stock availability

Our AMX range comes EX stock, meaning a quick and speedy delivery to your business.

No Obsolete part policy

All of our pumps come with our No Obsolete Parts policy, meaning if you have a Crest Pumps pump for 40 years, we will still be able to provide you with parts and an exact replacement to minimise disruption to your production line.

24 Month Warranty

With a 24 month warranty as standard, our magnetic drive pumps give an assurance to your business that the pump is quality built and will give you many years of trouble free operation.
