Sealless mag-drive pumps
Minimising the potential for chemical and environmental hazards by eliminating pump leaks, reducing downtime and extending service intervals were the challenges in a fluids recycling application at a leading refrigeration company.
As part of the reflux process, a range of refrigerants including HFCS’s (Hydrofluorocarbons), propane and butane needed to be transferred to the top of a distillation column.
An M Pumps magnetically coupled vane pump, model VM-15 with variable speed drive, was supplied by pumping specialists Michael Smith Engineers in late 2012. The combination of the magnetically coupled, sealless design and a stainless steel pump head has since provided impressive corrosion resistance and effective containment of all the process fluids.
There are no rotating seals to fail, so leak-free pumping is assured and consequently the refrigeration plant is benefitting from a reduced environmental hazard and no repair costs associated with the seal failures of the previous pump. The extended pump operation between servicing also means reduced downtime.
