3. Fluid Specifications

We recommend that all Quincy rotary screw vacuum pumps be filled with QuinSyn

synthetic fluid. QuinSyn

QuinSyn

F or QuinSyn

IV is available from any authorized Quincy distributor. For applications requiring a food

grade fluid, we recommend QuinSyn

F. Sustained (3 hours or more) discharge temperatures over 210°F require the

use of QuinSyn

HP fluid.

NOTE:

Failure to follow the above recommendation will adversely affect your warranty.

4. Fluid Life

QuinSyn

fluid can be used between 4,000 - 8,000 hours depending upon application and recommendations from the

fluid analysis. QuinSyn

F (food grade) and QuinSyn

IV can be used between 2,000 and 3,000 hours under good

operating conditions. Draining of the fluid should be done while the fluid is hot to carry away more impurities. It is

strongly suggested that a reputable fluid analysis program be followed to establish fluid change intervals.

A free service provided with the use of QuinSyn

products is a fluid analysis. This analysis provides the end user

with important information regarding the performance of the fluid and in detecting any special problems that might

arise. Fluid samples should be taken at the time of fluid filter changes or at 1,000 hour intervals or sample as directed

by analysis report. Fluid sample bottles, labels and instructions are provided with the vacuum pump package at the

time of shipment. Additional sample bottles may be purchased through your distributor. Drain off all water prior to

taking fluid sample.

5. Water Removal

Water vapor may condense in the separator reservoir and must be removed. The frequency with which water must

be removed is determined by the inlet vapor conditions. To drain water from the reservoir, turn the vacuum pump off

and let set for at least 15 minutes. Then open the drain valve. Water is heavier than the vacuum pump fluid and will

collect at the bottom of the reservoir. When the drain is first opened some fluid may come out before the water starts

to flow. Close the valve when the water flow changes to fluid. Make certain that there is no pressure in the reservoir

before opening the drain valve.
