Carbon fibre reinforced CFRETFE and PFA linings can be supplied to meet many varying duties. PFA being a natural unfilled material generates fewer contaminants and makes it ideally suited for transfer of high purity chemicals.
• MDM50-2 and 65-2 are only CFRETFE version.
The low head (maximum head of 65 m or less) series has a twolayer structure (pressure resistance 1.0 MPa) in which the rear casing is reinforced with an FRP (fiber reinforced plastic) rear casing cover. The high head models MDM25-3 and 40-2 types have a special three-layer structure (pressure resistance of 1.6 MPa) with one layer added to the rear casing and FRP rear casing cover. MDM50-2 and 65-2 models have a two-layer structure (withstand pressure of 1.6 MPa) in which the rear casing cover is reinforced with a CFRP (carbon fiber reinforced plastic) rear casing cover.
Even if the bracket is back-pulled, the rear casing is fixed with the rear casing support and bolts to the front casing side, so there is no leakage of the used liquid. A 2-step disassembly structure that considers safety.
The pump design features a mechanism to withstand dry running. High magnet power of the rare earth magnets prevents the magnet capsule coming into contact with the thrust ring of the rear casing, thus preventing melting of fluororesin components due to heat generation. This greatly improves resistance against dry running in comparison with conventional magnetic drive pumps made of fluororesin.
High head models MDM25-3 and MDM40-2 now join MDM Series which is favoured as fluoroplastic made process magnet drive pump. The models obtain 74 meters head (50Hz), 107 meters head (60Hz) to expand the application. We also have a lineup of MDM50-2 and 65-2 types with high flow rate and high lift specifications. Both cover a maximum flow rate of 1400 L/min and a maximum head of 85 m (60Hz).
