Instruction Manual VPD-25 IM 12 FEB 2018
1.0 INTRODUCTION
The Novatec VPD vacuum pump is designed to pneumatically convey plastic pellets or powders in a
vacuum conveying system. It does this by creating a vacuum to “pull” air through the piping system.
Plastic pellets or powders are introduced into the moving air stream in various ways, including
through the use of probes, pick-up tubes, and rotary air locks. The VPD is used in conjunction with
vacuum chamber station valves, etc. to form the conveying system, which is controlled with either
Master Control or Distributed Control Panels. Several vacuum power units may be designed into the
system as required. Vacuum conveying systems typically distribute material from silos, surge bins,
blenders, or drying hoppers to processing machinery.
2.0 WARNING
Always disconnect power before servicing. Only qualified technicians should service, maintain, or
repair the VPD. Before using this equipment, read in detail the product bulletins and other
information found in this manual. A safe installation is necessary before operating the equipment.
The instructions should be understood and followed before installing or operating the equipment.
3.0 OPERATING LIMITATIONS
Operating At Higher Altitudes…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 VPD pumps must be adjusted on site to prevent the pump from damaging itself or the motor
by attempting to compress air of reduced density to an unsafe level. Contact Novatec Engineering or
Service at the number on the front cover of this manual when operating the pump at 3000 ft or higher
elevation.
Blower exhaust temperature and motor cooling are a function of both vacuum level and elevation.
Blower exhaust temperature must not exceed 300°F to avoid premature blower failure.
Decreased motor FLA limits may require alternate overload protection or increased frame size / hp.
3.1 Seek Time
Excessive starting and stopping of the pump will reduce blower and motor life and void the
warranty. Seek Time is a control parameter that allows your pump to operate for short
periods in vacuum break mode (no vacuum loading) while the system control searches for
new demands. Using the Seek Time feature, pump starts must be limited to 12 per hour to
prevent premature failure. The minimum Seek Time for a pump is 240 seconds
to prevent
exceeding 12 starts per hour. Optimum Seek Time may be set dependent upon pump
capacity, utilization, number of stations, capacity of each vacuum chamber, and individual
station throughputs.
(See your control panel instruction manual for information on Seek
Time)

4.0 UNPACKING
Caution should be exercised to see that the equipment is not handled roughly. The crate must be
removed carefully. The machine must not be used to pry against Do not pry against the machine when
removing the crate. The vacuum power unit is usually shipped completely assembled and requires no
further attention prior to installation. Note any shipping damage on delivery receipt and report
immediately to trucking company.
5.0 GENERAL INSPECTION
When the unit is unpacked, make a visual inspection looking for missing parts or damage that may
have occurred during shipment. Report any missing parts to Novatec immediately. All electrical and
mechanical connections should be checked for tightness, as vibration during transit may cause them
to loosen.
IMPORTANT: Before placing the vacuum pump into service, be sure oil has been put in the pump, as
oil may have been drained following factory quality control testing. See page 9 for lubrication
guidelines.
NOTE: Replacement blowers are shipped without oil installed.

6.0 MECHANICAL INSTALLATION
Only qualified technicians familiar with local and national codes should install the equipment. Connect
the vacuum lines as shown on the installation drawings. Connect the compressed air (80-120 psig) to
air actuated valves as required.
7.0 ELECTRICAL INSTALLATION
Connect the proper power supply (check nameplate) through a main line disconnect (field supplied) to
terminal connections L1, L2, L3 and ground into the VPD control cabinet that contains the motor
starter. This is the only power required, as the unit is completely pre-wired. Connect additional control
wiring from the remote mounted master control panel to the vacuum power unit as shown on the
electrical wiring schematic for the master control panel. Verify the correct rotation of the motor with the
directional labels on the assembly.

10.0 MAINTENANCE AND INSPECTION SCHEDULE
It is recommended that maintenance and inspection is done on a scheduled basis. Maintenance
requirements will naturally vary widely for each installation and specific operating conditions. It is
suggested that a complete inspection be performed with the necessary maintenance at the end of the
first day, the first week, the first month and the first 3 months. These inspections will be indicative of
how often future maintenance will be necessary.
EVERY WEEK
Inspect the Filter cartridge. Clean or replace as required. Remove any fines collected from the catch
pan. This time interval should be shortened if experience indicates unusual dust loading.
Check the system for air leaks and correct as required.
EVERY MONTH
Inspect the vacuum breaker valve filter/silencer. Clean or replace as required.
EVERY 3 MONTHS
Units equipped with permanently lubricated motor bearings do not need lubrication. All motors should
be examined on an individual basis.
Units equipped with ball bearing motors are factory greased and should be re-lubricated with a high-
grade ball bearing grease rated for temperature and duty cycle required.
WHEN ADDING LUBRICANT
1. Remove filter plugs at the bearings and install grease fittings suitable to your grease gun. Also,
remove the drain plugs at the bearings.
2. Add ball bearing grease until all of the old grease is expelled through the drain hole.
3. Run motor with drain plug removed to eliminate excess grease.
4. Clean and replace drain plugs.
5. Check motor (s) amperage (see Engineering Data Sheet).
EVERY 6 MONTHS
Check for loose electrical connections. Tighten all bolts and nuts. Check V belts. Adjust or replace as
required.

11.0 BLOWER MAINTENANCE
ROOTS/DRESSER BLOWERS
Before starting pump, be sure oil has been put in the gearbox, as OIL MAY HAVE BEEN DRAINED
FOLLOWING FACTORY SHOP TESTS.
NOTE: ALL BLOWERS SENT AS REPLACMENTS ARE SHIPPED WITHOUT OIL.
Root’s recommends using lubrication oil manufactured by Royal Purple that is called SYNFILM GT
220. The Novatec Part Number for this oil is 03-0991 and is available in quart containers. If you
choose to use another brand of oil, be sure it is a good grade industrial type rust, oxidation, and foam
inhibited, non-detergent oil such as Mobil DTE BB, Texaco R&O 220, Amoco 220 or equal. See Table
