1 TM TM SERVICE INSTRUCTIONS Model 9670 Lubricant Pump 9670 DESCRIPTION Model 9670 Lubricant Pump is designed to pump light to heavy oils directly from the original container. This design features a 10:1 material-to-air pressure ratio allowing for the pump to also be used when pumping in longer systems. Maximum operating air pressure of 150 psi would, therefore, create 1500 psi of material pressure The pump's double-action, reciprocating pump tube is powered by an air-operated spool valve motor providing a constant delivery of material on both the upstroke and downstroke Used with an extension (not included), the pump can be mounted directly onto a remote tank or drum having 2" bung threads. Furthermore, the pump can be mounted on a wall bracket and used with a suction hose. Material Outlet (3/8" NPTF) NOTE: For sales information on extension, wall bracket, and suction hose, contact your nearest Regional Alemite Sales Office.

DO NOT exceed the pressure rating of any component in the system. Shipped Loose Figure 1 2. Read all instructions sheets, and any other explanatory material, carefully and thoroughly before attempting to assemble, disassemble, or operate the system. 3. Protect all material and air supply lines from damage or puncture. Especially note places where lines or hoses may be damaged when flexing or twisting, or by hot machinery and moving parts. 4.

2 service any component in the system. OPERATION 1. With pump suitably mounted, attach material outlet line (3/8" NPTF) to opening in lower body Thread adapter into air inlet (1/4" NPTF) and connect female coupler to air supply line. 3. Connect female coupler to adapter Gradually turn on air supply. CAUTION: Maximum operating air pressure is 150 psi. DO NOT EXCEED THIS LIMIT! 5. Allow pump to operate until it stalls out against built-up pressure. 6. Inspect system for air and material leaks. 7. System is now ready for use. AIRLINE ACCESSORIES: This air motor is lubricated at the factory with a teflon grease (Alemite #393590) and requires no additional lubrication except when servicing. CAUTION: Do not use an airline oiler on this pump. Lubricated air can cause the motor to malfunction. A fliter/water separator should be used. Wet air can washout the lubricant in the motor. SERVICE CAUTION: Before beginning service or attempting to disassemble any part of the unit, shut off air supply, reduce material pressure to zero, disconnect air and material supply lines, and remove pump from container or system.
