StanPumps vertical dry multi stage lobe and claw. Vacuum pumps are designed based on oil-free, non- contacting, four stage lobe and claw mechanism. It provides consistent vacuum at high efficiencies, lowest cost of ownership with adequate safety and performance standards. The new pump is of 400m3/h capacity with an ultimate vacuum of less than 0.05 mbar. These pumps can be used for distillation above 3PH and bellow 5pH. These pumps are free from process contamination and efficient generation. More distillate recovery compared to conventional.
