2 STAGE OIL-SEALED ROTARY VANE VACUUM PUMPS
GVD 28
FEATURES AND BENEFITS
• The pump is designed for reliable, long-term operation.
• Thermal overload device prevents overheating (single phase only).
• The pump is a free-standing unit.
• The drive is provided through a flexible coupling by a
single-phase or three-phase (four pole) motor.
• The motors are totally enclosed and are cooled by the
motor-cooling fan.
• Easy to use controls.
• Pressure die cast oil box with integral oil seals prevents oil
leaks.
• Gas ballast valve for large water vapour handling capacity.
• Externally approved to EN61010, CSA, C22.2 and UL61010.
• Oil distribution valve.
• Pumping chambers are air-tight.
• Oil sight-glass, two oil drain-plugs, inlet-port and outlet
nozzle all fitted as standard
