Drive Mechanism NOTICE All installation, maintenance, and repair work must be completed by qualified personnel. A 1-1/4 inch diameter shaft is provided to connect the lubricator to a rotary power source. A woodruff key and key way on the shaft are provided to aid in connecting this source. Install protective guards around all drive components. The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides and escape wire for the electric current. NOTICE The recommended speed of the box lubricator drive shaft is...

Three sight glasses (B) are provided in the reservoir at various levels to permit observation of fluid level (FIG. 3). 2. Remove the vent plug (A) on top of the sight glass and fill the housing sight well with oil to 3/8-inch below the discharge of the drip tube (FIG. 5). Oil level should not be allowed to drop below the bottom sight glass. 3. Replace the vent plug (A). Check the sight glass to insure that it is properly seated against the o-ring (D) to prevent air leakage into the sight well (FIG. 6). Pump Priming To prime the pump: 1. Turn the feed adjustment nut (C) on indicator stem as...

Pumping Rate During the pump suction stroke an amount of oil equal to the pump displacement is drawn through the drip tube into the sight well. The amount of fluid in the site tube indicates the pumping rate. NOTE: Allow sufficient time to insure an accurate rate indication. The drip tube flow rate is only accurate after the pump has operated long enough to stabilize the pressure inside the sight well. C There is a time lag at start-up, during low pumping rates, and during pump rate changes. Regulating Pump Rate The pumping rate is adjusted by hand during the pump suction stroke. • Turn...

Service Pressure Relief Procedure Service Instructions 1. Check lubricator operation by observing the drip tube. If the sight glass well pumps dry or no flow is observed, check the following points until the cause is determined and corrected. The equipment stays pressurized until pressure is relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the dispenser, or splashing fluid, follow this Pressure Relief Procedure whenever you: • Check the vent plug (A) for proper sealing. Any knicks or cracks in the rubber plug will cause an air leak into the sight...

2. If items listed in step 1 are not the cause, check the pump assembly. The following items should be checked before removing the pump assembly from the cover. • • Keep a spare pump on hand for use during emergencies and when the pump is being repaired. • If a spare pump is available, it will not be necessary to stop the equipment the lubricator is installed on or to empty the reservoir. Check the sight glass for inward leakage due to a crack in the sight glass, improper sight glass seating, or a defective o-ring. Repair as required (FIG. 6, page 6). Check for an obstruction in the drip...

If the sight glass continues to fill with lubricant: a. Check all terminal check valves for proper operation. a. If the level falls to less than 1/4 inch above the sight glass flange, add lubricant to the proper level (3/8 inch below the discharge of the drip tube) through the vent hole. b. If the level is too high, remove the vent plug and allow the unit to pump down before replacing the vent plug. b. Relieve system pressure, page 8. c. If valves are operating properly, disconnect the discharge tubing (E) (FIG. 10) When the unit is operating the sight level will vary depending on...
