From January 2015, there are new motor
efficiency requirements for electric 3-phase motors 7.5kW and
Motors 7.5kW and larger, need to be IE3, unless they are to be used
with a variable speed drive, in which case they can still be IE2.

||MDM have manufactured some H range centrifugal
pumps with a maximum ferrite level of 5% especially for a pharmaceutical
As the pumps are manufactured from solid bar, MDM could measure the
ferrite levels in the raw material, and ensure that only bars with a
ferrite level of less than 5% were used.
Then using special 0% ferrite welding rods, the pump parts were
Previously, MDM have manufactured H range centrifugal pumps with a
ferrite level of only 0.5%. But this involved buying a specially
formulated batch of 316L stainless steel.
It is believed that low levels of ferrite reduces the rouging seen in
some pharmaceutical systems.
MDM have introduced a new K3 range of strainers.
cheaper than the K2 range and are fitted with 'tri-clamp' clamp rings and the cartridge welded to the lid. These strainers can be fitted with
stainless steel wedge wire, woven wire mesh, sintered mesh or perforated
We have been supplying strainers with sintered mesh
cartridges since October 2010 .
They consist of a fine square weave mesh
and a support layer of square weave mesh, which has been sintered (fused
together) using heat and pressure to form a 2 layer laminate. This
provides a minimum pressure drop together with excellent backflush
Customers who like the strength of the wedge wire cartridge, but
dislike the slot design, have found the sintered mesh to be a good
With the ability to
manufacture tailor-made strainers, we have recently supplied specially
designed basket strainers to a distillery in Scotland.

||Vent valves are now supplied with FDA (Food and
Drug Administration) compliant materials as standard.
In many applications there is a requirement for the
materials to be FDA-compliant. This
applies to the wetted parts and includes the elastomers.

As the pound remains weak, buying British manufactured pumps
still makes more sense. Pumps imported into the UK have risen in
price by up to 30% over the last 3 years, whilst the pound has weakened by 30% against the Euro
since January 2007, and by 20% since January 2008. Whether you are based
in the UK or outside the UK, contact us or our distributors today to
benefit from the weak pound.
||MDM PUMPS LTD are one of the first companies to achieve the
latest quality standard ISO 9001:2008.
||New high efficiency D121 pump model launched.
Replacing the D2 & D2W pumps, the D121 has improved hygiene. It is
fitted with an improved cover joint ring, impeller locknut 'O' ring and
impeller shaft 'O' ring.
The D121 delivers pressures up to 2 bar.
||New high efficiency H141 & H241 pump models launched.
The H141 delivers pressures up to 3 bar and H241 up to 10 bar.
||MDM PUMPS LTD are pleased to announce the launch of their new high efficiency H161, H191 &
H221 pump models.
Compared with the previous models, they deliver up to 40% greater head
with an improvement in efficiency of up to 33% (therefore many
applications can be significantly cheaper).
The pumps share the majority of components with the original H160, H190
& H220 models, but incorporate new impeller and cover designs at no
The H161 delivers pressures up to 4.5 bar, H191 up to 6 bar and
the H221 up to 8 bar.
* According to the 'European Guide to Pump
efficiency for single stage centrifugal pumps' (European Commision 2003),
the majority of our pumps are classified as optimum efficiency selections
or efficient selections.
