Stage Belt Drive Vacuum Pumps
|This is our meat and potatoes vacuum pump for
a large variety of industrial and laboratory purposes. We have 5 vacuum pumps in this
category that we manufacture and they go into a wide spectrum of uses. They all basically
reach an ultimate vacuum pressure of .1 micron. Free air displacement runs from 29 liters
/ minute to 500 liters / minute. Any of the pumps can be configured for various electrical
requirements and sources including 115V, 220V, 240V, 380V, 460V, 3-Phase and Explosion
Proof. Electrical frequencies available of 50 or 60 Hz for either US
|They are oil sealed rotary vane pumps using
both an intake and exhaust stage (stator) to reach low pressures. The pumps all operate at
relatively low speed (600 rpm) making for a durable and long lived product.
It is not unusual for us to get a phone call for a 20-30 year old pump
that is still working.
The pumps are
manufactured predominately out of cast iron and use spring loaded cast iron vanes. The
pumps come mounted on a base, with a belt guard and motor of correct size. They are quiet,
heavy duty pumps. They have no elastomers internally to wear out except for the
which is external to the pump so these pumps can be depended on for years and years of
service if properly maintained. The larger 2 pumps the HyVac 28 and 45 employ a modular
approach to the intake stator (there are actually 3 in a 45) which allows for potentially
a less expensive repair should foreign materials be sucked into the pump.
All pumps come complete with a gas
ballast valve for purging water vapor and other foreign condensables.
All HyVac vacuum pumps come with a 1 year warranty.
