Yes, a check valve should be placed inline for either pressure or vacuum applications.

Vane breakage and increased potential for ingestion of foreign debris can result from running units in wrong rotation.

Filters should be inspected, cleaned and/or replaced every 500 hours.

Rotary vane units can be used for either vacuum or pressure except for separate drive lubricated models which are designed to be model specific for vacuum only or pressure only.

All separate drive units may be pulley-driven with the exception of the 67 series which require a 56C NEMA frame motor and must be direct coupled.

The max speed for a separated drive unit is 1,750 rpm.

Lubricated models require AD220 oil. Oilless model do not require lubrication.

You can buy AD220 oil from Kinequip here

AD220 is 10wt. SAE high detergent petroleum base oil. Any substitute should be the same. Do not use synthetic oil blends.

Use the fill line on the oil reservoir to gauge oil consumption.

Lubricated motor mounted units use siphon lubricators which are preset to dispense appropriate amounts of lubricant. Lubricated separate drive units use gravity feed lubricators which can be adjusted to reduce oil feed rate by adding more wicking material to base of oiler.

Remove the end plate of the unit allowing access to the vanes. Remove the vanes from the unit. Use AH255D to flush out the inside of the unit, end plate and vanes. Blow out the inside of the pump, and wipe down the vanes and reassemble the unit. You should also replace the filters at this time.

No, the bearings are shielded or sea
