MDM Pumps Ltd specialises in tailor-made hygienic
pumps, vent valves and strainers, for the pharmaceutical, brewery, soft drinks,
dairy and food industries. All our products are built to last and are fully cleanable
in place: liquid contact surfaces are smooth and crevice-free, with minimum 3mm
radii. We manufacture products using components machined from solid stainless
steel 316L bar (see footnote 1) - without using castings, pressings or spinnings
(see footnote 2)
- and use FDA-compliant seals.
If you are pumping products such as sewage, river water, sea water or petrochemicals, then you do not need a pump to such a high specification as this.

1Apart from the motor, all metal parts are stainless steel 316L except for those in the mechanical seal, which are typically stainless steel 316, and some of the FSB/cowl rails and cowl sheet (where supplied), which are stainless steel 304. Low ferrite stainless steel 316L (1.4435) is available on request.
We no longer use castings, pressings or spinnings for H, CH, D or GP pumps, vent
valves or strainers because cast steel is vulnerable to porosity and surface
pitting which makes it less satisfactory, and pressed or spun components are
generally thinner which results in a shorter life. Each of our impellers is machined from a single billet (back plates for closed
impellers are separate components).
