Refer to the bill of lading or the gold-colored system information plate attached to the system (see image below). Gold-colored system information plate Parts should be purchased from the nearest authorized DEKKER Vacuum Technologies, Inc. (hereafter referred to as DEKKER) representative (visit www.dekkervacuum.com to find a distributor near you via the Distributor Locator) or from the vacuum pump system supplier.
SAFETY All vacuum pumps, systems and/or compressors (hereafter referred to as the Product) offered by DEKKER have been designed and manufactured for safe operation. However, the responsibility for safe operation rests with those who use and maintain these products. The safety department where the product is installed should establish a safety program based on OSHA, federal, state, and local codes.
THEORY OF OPERATION The DEKKER HullVac rotary piston vacuum pump is designed and manufactured to achieve a high level of performance. These pumps create a vacuum with a piston that moves in a circular path. As it rotates, pressure is decreased on the inlet side and increased on the discharge side. The two sides are separated by a film of oil between the piston and the cylinder.
It is the responsibility of the receiver to thoroughly inspect upon delivery. The customer should take photos of the system as it arrives and send to DEKKER if there are any issues. Failure to report these issues within the freight carriers’ undiscovered damage window can result in denial of warranty claims.
Oil temperature should be maintained at 165°F. Minimum oil temperature should not be below 55°F. The increased sealing oil viscosity caused by low temperature can lead to internal galling and motor overload fault. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
DEKKER includes a wiring diagram in the control panel for use by the installer. DEKKER recommends a main disconnect switch be fitted between the vacuum system and the incoming power. Wire the motor using appropriate starters and fuses to comply with local electrical codes.
Discharge Piping DEKKER recommends, as a minimum, CPVC discharge piping as discharge temps may exceed +170°F. CPVC is rated for 200°F max, and PVC is only rated for 140°F max. Discharge piping must be at least the size of the pump exhaust port.
Alarm Silence Button: The alarm silence button is used to silence the audible alarm, but the light will remain on unless alarm condition has been corrected. Alarm Reset Pushbutton: The alarm reset pushbutton is used to reset an alarm condition when the condition has been rectified. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
Remove the belt guard and rotate the pump two complete revolutions hand counterclockwise direction. This will clear accumulated oil from the pump housing that can collect during long inactive periods. Reinstall the belt guard. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...

4. After the proper operating tension has been applied to the belts, double check the following: A) Parallel position of the sheave shafts. B) Correct alignment of sheave grooves. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
Tensioning Table and installation image courtesy of Dodge PT Manual MN-4002 Notes: 1. Use approximately 130% of above values to tension a new set of belts. 2. Use closest sheave diameter for sizes not shown. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...

140-160°F range at the solenoid body. The casing temperature will rise faster and be higher at higher suction pressures. During any operation, the casing should not rise above 180°F. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
If needed, replace the valve deck springs and wear plates. Examine the belts for signs of excessive wear and replace as needed. Verify if motor lubrication is required for pump motor. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
Seal Fluid/Oil The product(s) are shipped with DEKKER’s specially formulated HullVac seal fluid (hereafter referred to as oil). DEKKER recommends that this oil be used to obtain the ultimate performance from the HullVac product and to maintain the 3-year warranty period.
The approximate oil capacities are given in the Standard System Capacities table below. Standard System Capacities System Capacity (gal) HV55A HV140A HV160 HV412XT HV450 HV635 HV850 HVC35A HVC65 HVC100A HVC180 HVC340 DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
Oil Analysis DEKKER offers oil analysis to customers, regardless of the age of their system. Collect approximately 1 pint from the machine in a clean bottle of any type and secure it. On the bottle and/or a packing list, please include the following: system serial number, the type of oil, the run hours on the oil and machine, and note any problems you are having with the system if applicable, as well as the system process conditions.
Check if the pump has seized by removing the belt guard and rotating the belts by hand (disconnect power first). If a rubbing noise or binding is observed, contact the factory. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
Ensure that the pump is pulling a deep vacuum level (deeper than 100 torr for single-stage and 10 torr for two-stage). Stop system and disconnect power. Confirm oil level is not too high. Confirm that pump is using factory recommended oil. Ensure that discharge piping is arranged correctly. DEKKER Vacuum Technologies, Inc. – HullVac / September 2016...
