2 STAGE OIL-SEALED ROTARY VANE VACUUM PUMPS
GVD 80
FEATURES AND BENEFITS
• Advanced pressurized oil circuit to give effective lubrication
even under high gas loads.
• When the pump is switched off, the spring loaded distributor
valve provides oil and air suck-back protection.
• Gas ballast control to assist in handling high water vapor loads.
• Industrial roller bearings on drive shaft for ultimate
reliability and long, trouble free life.
• Full height oil sight glass for easy checking of oil level and
condition.
• Easy change oil filter, with oil filter condition gauge on larger
models.
• Central inlet port to allow easy mounting of mechanical booster
pump if required.
• Easy to maintain, with convenient service kits and international
customer support.
• A wide range of accessories to match your application needs
• The pumps and accessories can be supplied either as individual
components or as fully systemized, factory-tested combinations.
