GENERAL DESCRIPTION
Model WLM2203A-XX series two-ball double acting pumps are in­tended to be used primarily for oil transfer and delivery systems. It isbest to use this pump with low -- medium viscosity fluids. It uses carbon steel and other materials which make it compatible with most petroleum based lubrication products. The two-ball design provides better priming of the lower foot valve. Double acting pumps will deliver material on both the up and down stroke. NOTE: If this pump was purchased separately (not part of a system), consult your sales representative for compatible dispensing accesso­ries which will best match the application. All accessories must be able to withstand the maximum pressure developed by the pump.
OPERATING AND SAFETY PRECAUTIONS
READ THE GENERAL INFORMATION MANUAL INCLUDED FOR
ADDITIONAL OPERATING AND SAFETY PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
STATIC SPARK. Can cause explosion resulting in severe injury or
death. Ground the pump and pumping system.
EXCESSIVE INLET PRESSURE. Can cause explosion resulting in
severe injury or death. Do not exceed maximum operating pressure of 25.5 bar (370 p.s.i.) at 8.5 bar (123 p.s.i.) inlet air pressure. Do not run pump without using a regulator to limit air supply pressure to the pump.
INLET PRESSURE TO PUMP MOTOR
PUMP RATIO X
Pump ratio is an expression of the relationship between the pump motor area and the lower pump end area. EXAMPLE: When 125 p.s.i. (8.6 bar) inlet pressure is supplied to the motor of a 3:1 ratio pump it will develop a maximum of 375 p.s.i. (25.9 bar) fluid pressure (at no flow) -- as the fluid control is opened, the flow rate will increase as the motor cycle rate increases to keep up with the demand.
MAXIMUM PUMP
=
FLUID PRESSURE
EXCESSIVE MATERIAL PRESSURE. Can cause equipment failure
resulting in severe injury or property damage. Do not exceed the maximum material pressure of any component in the system.
NOTICE: Thermal expansion can occur when the fluid in the materi­al lines is exposed to elevated temperatures. Example: Material lines located in a non-insulated roof area can warm due to sunlight. Install a pressure relief valve in the pumping system.
Replacement warning label (pn 94520) is available upon request.

PLACING INTO SERVICE
AIR AND LUBRICATION REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the pump to op­erate more efficiently and yield longer service life to moving parts and mechanisms.
Install an air line filter to provide good quality clean and dry air. Install
it up stream from the regulator.
Use an air regulator on the air supply to control the pump cycle rate.
Install the regulator as close as possible to the pump.
In most installations, lubrication is not required. If the pump needs to
have lubrication, install an air line lubricator and supply it with a good grade of non-detergent oil or other lubricant compatible with Nitrile seals and set at a rate not to exceed one drop per minute.
INSTALLATION
Mount and secure the pump as required for the application.
Attach a ground wire from the pump ground screw to a suitable
ground.
Connect a fluid hose to the pump outlet. In most cases a pipe sealant
SERVICE
PUMP DISASSEMBLY / REASSEMBLY
NOTICE: The unique design of this pump allows for quick basic pump service without total removal from the drum (refer to the views below).
DISASSEMBLY proceduresare for the installation of repair kitparts. Disconnectair supply and relieve all system pressure
remove the parts, inspect parts for damage, nicks or excessive wear and determine if any parts will need replacement. Follow the three disassembly steps in the detail views below and place the pump on a clean bench.
1. Remove (1) bolts. Remove (18) packing, (17) bushing and (16) “O” ring.
2. Remove (36) adapter, releasing (10) muffler.
3. Grasp the (11) cylinder and remove the (20, 14) piston assembly.
4. Remove (15) lower cap and (3) track gasket. Remove (12) retaining ring and (48) washer, then pull (14) piston off (20) piston rod.
5. Remove (2) cap and (3) track gasket. Push on the large o.d. end of the (7) spool to remove the (4) sleeve. Grab the nose of (7) spool and pull out. Repeat for other sleeve and spool.
REASSEMBLY bores with Shell Gadus S2 U1000 upon assembly. Replace all soft parts with new ones included in the repair kit.
Note: Refer to the illustration (figure 2) for “U” cup lip seal direction.
1. Replace the seals on both the (7) spools and (4) sleeves.
- All threads are right hand. Refer to figure 2. These
prior to servicing. Carefully
- Thoroughly clean and lubricate all seals and
should be used on thread connection. Tighten all fittings. Use cau­tion not to damage threads.
OPERATION
START-UP
1. Turn the air regulator to “0” pressure setting.
2. Immerse the lower pump end into the material.
3. Open the dispensing device.
4. Start the pump cycling slowly by raising the pressure to 1.4 - 2.1 bar (20 - 30 p.s.i.).
5. Close the dispensing device. Allow the pump to stall and build line pressure. Check for any leaks and tighten fittings as needed. Adjust pressure as required for the application.
SHUTDOWN
Disconnect the air supply from the pump if it is to be inactive for a few
hours. Open the dispensing device to relieve line pressure.
2. Locate the valve chamber on the (11) cylinder where the 3/8’’ dia. hole is located and install one of the (4) sleeves. Insert the (7) spool from the opposite end. Next, install the remaining sleeve and spool.
3. Replace the (3) track gasket and install (2) cap.
4. Replace the (13) piston “U” cups (refer to figure 2 for proper orienta­tion). Replace the (19) “O” ring and assemble (14) piston to (20) pis­ton rod and retain with (48) washer and (12) retaining ring.
5. Install the (20, 14) piston assembly using great care to collapse the outer lip of the second “U” cup, allowing it to slip into the cylinder.
6. Replace the (3) track gasket and install the (15) cap. Install the (16) “O” ring onto the piston rod, replace (17) bushing and (18) packing.
7. Replace the (25) “O” ring and re-attach the (24) inner check.
8. Slide the pump assembly back into the (26) base / lower pump sec­tion. Press the sections together and align the air inlet and pump out­let as required and replace the four (1) bolts and (27) nuts (tighten to 9 Nm (79.7 in. lbs).
TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
Be certain to check for non-pump problemsincluding kinked,restric-
tive or plugged inlet / outlet hose or dispensing device. Depressurize the pump system and clean out any obstructions in the inlet / outlet material lines.
Check all seals, including track gaskets.
Check direction of “U” cup lips.
A) Remove the four
nuts from the base of the Air Motor.
