HVC Series Double Stage Rotary Piston Vacuum Pumps - 18 to 960 CFM
Two Stage Performance At a Single Stage Price
HullVac Pump's Double Stage Rotary Piston Vacuum Pumps feature the next generation of vacuum pump technology. If micron range ultimate vacuum and high reliability is required, HVC Series Vacuum Pumps are an excellent choice.
Ruggedly constructed from chemical resistant cast iron, HVC series vacuum pumps feature hardened shafts and Viton® shaft seals. Our rotary piston design and low rotational speeds reduce wear. Replacing a single stage pump with a compound pump increases vacuum system performance by reducing pump down time and base pressure. When low base pressure is required, a less expensive, lower capacity compound pump can equal the performance of larger, single-stage pumps.
Upgrade now and get all the improvements in one durable, reliable, tough pump.
