Waste problem solved

Semiconductors are an essential component in a diverse range of products. Waste acids and alkalis are among the unavoidable by-products generated in the manufacturing process and these liquids require treatment prior to them being discharged from site.

Previously, mechanically sealed centrifugal pumps were used to transfer effluent waste into a treatment system. However, problems were occurring with seal leakages resulting in downtime, expensive repair bills and the associated clean-up costs from the spillages.

M Pumps' magnetically coupled centrifugal model C MAG-P100 in PVDF, available from Michael Smith Engineers, was selected by General Waters UK which assists the semiconductor manufacturer in meeting effluent targets at its Newport, South Wales manufacturing plant.

The combination of the magnetically coupled design and PVDF pump head ensures optimum corrosion resistance and effective containment of the waste acids and alkalis.  There are no seals to fail, so leak-free pumping is assured and consequently the manufacturing plant benefits from reduced chemical and environmental hazards and extended pump operation between servicing.
