Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable. SKIN INJECTION HAZARD High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This may look like just a cut,...

WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer. • Do not leave the work area while...

Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. d This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop pumping and before cleaning, checking or servicing the equipment. 1. Stop lube pump. 2. If installed, close oil supply valve located upstream from pump. 3. If installed, open drain valve located downstream from the pump. 1. Ensure the pump mounting surface on the reservoir...

Setup NOTICE Any pressure applied to the pump inlet has the potential to cause unrestricted flow from the pump outlet even in a pump that is at rest or adjusted for zero stroke. To prevent this from happening, install a check valve of a comparable pressure rating at the pump outlet. NOTE: The internal “discharge check valve” does not have a spring and is rated at zero psi. a FIG. 2 b. For all installations (whether the tube needs to be trimmed or can be used without trimming), press strainer onto end of the suction tube until it “bottoms” (FIG. 3). 1. Expel all air from pump and relieve pressure...

Gravity Fed Models (FIG. 5) NOTE: In the following instructions, the fill line refers to the inlet line. 1. Remove and discard the sight well plug (1) and outlet plug (5). 2. Fill the sight well (2) to the top with appropriately filtered oil. 1. Remove the sight well plug (1) and outlet plug (5). Discard outlet plug (5). 3. Operate the hand priming assembly (3) until the oil level drops below the end of the drip tube (4) (FIG. 4). 2. Fill the sight well (2) to the top with appropriately filtered oil. 4. Apply thread sealant (user supplied) to fill line fitting. 3. Operate the hand priming assembly...

Alarm Pump Models (FIG. 7) 3 NOTE: In the following instructions, the fill line refers to the inlet line. 5 1 6 FIG. 6 1. Remove and discard the inlet plug (1) and outlet plug (5). 2. Apply thread sealant (user supplied) to fill line fitting. 3. Connect fill line to inlet (2). 4. Torque fill line fitting to 85 + 10 in. lbs (9.60 + 1.13 N.m). 5. If installed, open oil supply valve located upstream from the pump. 6. Operate the hand priming assembly (3) until the oil expelled from the outlet (6) if free of air. FIG. 7 1. Remove the sight well plug (1). 2. Fill the sight well (2) to the top with...

Connecting Lube Lines to Pump: Suction, Gravity and Pressure Fed Pump Models Only 3. After startup, ensure sensor is activating correctly. NOTE: The lube line refers to the outlet line supplying lubricant to the lubrication points. 1. Apply thread sealant (user supplied) to lube line fitting. 2. Connect lube line to pump outlet (6), (FIG. 8)(also see pages 15 and 16). 3. Torque lube line fitting to 50 + 5 in. lbs (5.65 + 0.6 N.m). Pump volume is controlled by an external adjusting screw (8) (FIG. 9). Turning the adjusting screw changes the length of the piston stroke which changes the pump discharge...

3. For Suction Fed and Gravity Fed models only: With the lubricator operating, count the drops from the drip tube (4) falling into the sight well (2) for one minute. Calculating Output Capacity The number of drops observed falling in the sight well equals the amount of oil discharged by the pump. The pump volume can be adjusted using the adjusting screw (8) (FIG. 9) to change the piston stroke. (See Adjusting the Pump.)

Specifications Table 1 Drops per Stroke Table Section of Table Applies to Suction and Gravity Fed Models Only Piston Diameter Cubic Inch/Stroke Strokes/Minute - Maximum - 50; Minimum - 3 Allowable viscosity range independent of temperature: 80-5000 SUS. Cubic cm/Stroke Stroke Length - Maximum 1/2 inch (12.7 mm) † Refer to your manufacturer’s specific instruction manuals to ensure your box and lubrication system are rated for the selected pressure. 1 Based 2 on 500 SUS oil at 70°F ambient. Heavier oil will produce fewer but larger drops. When approaching maximum outputs, some oils will stream...
