Cleaning Lubricated Rotary Vane Pumps Using Proclean 68D

Each DuraVane rotary vane vacuum system is tested and checked at the factory prior to shipment to ensure trouble-free operation. In the unlikely event you encounter a problem, we recommend that you consult with your local distributor for parts/service. Remember, when calling for service, part, or system information, always have the pump or system model number and serial number ready.
