Drum Vacuum System
Drum Vacuum Pump
The drum vacuum system consists of the drum vacuum pump and the drum vacuum
drive. The drum vacuum system connections to the ThermoFlex Wide output device
are shown in Figure 1 on page 8.
The drum vacuum pump enclosure has the following features:
•
Splash-proof design for interior or exterior installation
•
Acoustic insulation that limits attenuation to 70 dB
•
Integrated cooling fan and removable air filter at intake duct
Location
Beause the drum vacuum pump generates a significant amount of heat during
normal operation, the enclosure should not be installed in the same room as the
output device.
The preferred location for the drum vacuum pump enclosure is an equipment room
that is thermally insulated from normal working areas in the building, and that has
forced ventilation or cooling. Alternatively, the pump may be mounted outside if the
environmental conditions can be maintained within acceptable limits.
When selecting a location, consider the following:
•
Ambient air temperature around the enclosure must not exceed 40
and must not go below -5
keep the temperature below the upper limit.
•
There must not be prolonged exposure to direct sunlight.
•
The intake and exhaust ports (ends of the enclosure) must have at least 300
mm (12 in.) clearance from all obstacles to allow the cooling air to flow freely.
•
There must be shelter from snow, ice and any debris that may impede the free
flow of cooling air.
•
There must be service access for changing the intake filter and removing the
cover fasteners along the sides.
•
The maximum length of tubing needed to reach the output device should be 15.2
m (50 ft.).
For exterior installations, a shed or shelter should be provided to protect against
debris and solar heating.
Installation
The drum vacuum pump enclosure should be installed on a concrete pad, or a solid
base, to which the enclosure can be fastened. The pump enclosure should be
permanently mounted to the floor using four bolts or studs through four 1/2 in. (12.7
mm) holes in the enclosure base. The enclosure footprint and the layout of the
mounting holes is shown in Figure 5.
