Information shown is for standard VPDB series Positive
Displacement vacuum pumps. Specifications will be
reduced for 50Hz. Specifications will change when the
pump is operated at elevations 2000 ft. or more above
sea level (see section below).
NOTE:
Refer to special job drawings for custom unit
information if applicable. Verify nameplate information on
motor before installing and operating. All information is
subject to change without notice.
10.0 PARTS LIST
9.0 OPERATING AT HIGHER ELEVATIONS
(3000 ft. above sea level or more)
Atmospheric pressure is lower at higher elevations and
as a result, the compression of air by the pump requires
more work for vacuum conveying. In these higher
altitude applications, the pressure relief valve of VPDB
pumps must be adjusted to prevent the pump from dam-
aging itself or the motor by attempting to compress air of
reduced density to an unsafe level. Failure to adjust the
pump will void the pump warranty.
When the end-use site is known, Novatec endeavors to
pre-
adjust the vacuum pump’s performance at the factory
to compensate for elevations above 3000 feet. Novatec
then labels the vacuum relief valve accordingly. If your
pump-use site is 3000 feet above sea level or more, and
no indication of pre-adjustment is present on the pump
assembly, please contact Novatec Engineering or the
Novatec Service Department at the number on the front
cover of this manual to get instructions for adjusting your
VPDB pump for use at elevations at 3000 feet or more
above sea level.
