Features of Vacuum Prime Assist Pumps

1. Reduce operating costs and vacuum pump does not consume oil, there is no level control or recharge, or condensate is discharged every day;

2. Higher performance. Our vacuum assisted self priming pump system allows faster start-up and constant water flow from the well point system;

3. Optimize operation. Self priming centrifugal pump can ensure operation in case of vacuum pump failure. Because of treat large-diameter solids make the device suitable for well point systems and sewage pumps;

4. Easy to maintain. In the diesel engine version within reach when changing the oil, air and fuel filters and maintaining the starter motor and alternator.
