Product Description

AMXi Plastic Magnetic Drive Pump

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. Eliminating the need for a mechanical seal and therefore making magnetic drive pumps completely leak proof.

The AMXi range of magnetic drive pumps are designed to provide you with a long service life and minimal running costs. Operating at over 70% efficiency, AMXi pumps can be relied upon to work in the toughest of conditions including high corrosion, temperature and ATEX zones 1 and 2.

Reduced Life Cycle Cost

The patented run dry technology built into the AMXi helps protect your pumps from a failure in the process. Most mechanically sealed pumps will fail when run dry, causing dangerous leakages and costly clean up bills as a result. However with the AMXi, the pump can run dry for a number of hours alleviating process problems and avoiding damage to the pump.

The second patented design feature of the AMXi range will increase the mean time between servicing, reducing overall maintenance costs of your process. Should the AMXi pump be subjected to adverse operating conditions, vibration would normally reduce the life of the internal parts. However, with the dynamic buffer system acting as a shock absorber between the impeller and the casing, the pump is protected as a result, thus minimalising wear and prolonging the pumps service life.

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.

The AMXi range operates at over 70% efficiency. Lower electricity costs also come from the use of high efficiency IE3 motors (where available). We also trim the impeller diameter to your required duty point, increasing process efficiency. Inverters are also available to achieve the ultimate efficiency in your system.
