Combination Vacuum Pumps

Combination vacuum pumps integrate a high performance rotary vane pump with a chemical-resistant diaphragm pump to create a low maintenance, longer-lasting pump. The diaphragm pump removes the condensable vapors in the rotary vane pump before they can contaminate the oil, thus extending the life of the oil and ultimately the life of the pump. Pump oil lasts up to 10 times longer than in conventional rotary vane pumps under virtually any condition. Long periods between oil changes reduce cost and down time.
