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 3 pH and below 3pH. These pumps are free from process contamination and efficient generation. More distillate recovery compared to conventional wet vacuum pumps.
