PLACING INTO SERVICE
OPERATING AND SAFETY PRECAUTIONS
WARNING READ THE GENERAL INFORMATION MANUAL INCLUDED FOR OPERATING AND SAFETY PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
WARNING EXCESSIVE INLET PRESSURE. Can cause ex plosion resulting in severe injury or death. Do not exceed maxi mum operating pressure of 7500 p.s.i. (517.2 bar) at 150 p.s.i. (10.3 bar) inlet air pressure. Do not run pump without using a regulator to limit air supply pressure to the pump.
PUMP RATIO X | = | MAXIMUM PUMP |
INLET PRESSURE TO PUMP MOTOR |
| FLUID PRESSURE |
Pump ratio is an expression of the relationship between the pump motor area and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is supplied to the motor of a 50:1 ratio pump it will develop a maximum of 7500 p.s.i. (517 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.
OPERATION
START |
|
|
| |
1. | Turn the air regulator to | pressure setting. Connect the air hose. | ||
2. | Prime the pump by cycling slowly, raising the pressure to 20 30 | |||
| p.s.i. Cycle the pump until the test grease and any trapped air has | |||
| been purged from the system. |
|
| |
3. | Close the dispensing device. Allow the pump to build line pressure | |||
| and stall. Check for any leaks and re | fittings if needed. Adjust | ||
| air pressure upward as required for the application. |
| ||
NOTICE: If the pump does not prime soon after initial start | establish | |||
what the problem is to prevent unnecessary damage to the pump plung er.
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.
WARNING EXCESSIVE MATERIAL PRESSURE. Can cause equipment failure resulting in severe injury or property dam age. Do not exceed the maximum material pressure handling capability of any component in the system.
Thermal expansion hazard. This can occur when the fluid in the ma terial line is exposed to elevated temperatures. Example: Material
line located in a non roof area can warm due to sunlight. Install a pressure relief valve in the pumping system if this condition could exist.
AIR AND LUBRICATION REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the pump to op erate more efficiently and yield longer service life to moving parts and mechanisms.
•Use an air line filter to provide good quality clean and dry air, install it up stream from the air 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 between the pump and
the air regulator and supply it with a good grade of non oil or other lubricant compatible with Nitrile seals. Set at a rate not to exceed one drop per minute.
SERVICE
Refer to the basic pump manual for service instructions which also cov ers disassembly and reassembly for installation of the rebuild kit.
TROUBLE SHOOTING
If the pump does not cycle or will not deliver material.
• Be certain to check for non problems including 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.
INSTALLATION
Assemble components included in the package as shown in figure 1 (page1). NOTE: In rigid plumbing applications, use flexible material and air supply hoses when attaching the pump to prevent damage by vibra tion.
1.Thread the pump bung adapter into the pump cover, insert the pump into the bung and then secure with the thumb screws provided.
2.Install the outlet adapter, material hose, swivel and gun.
3.Lay the follower on top of a full bucket of grease, feed the lower pump end into the follower and secure the cover with the thumb screws.
4.Attach a coupler to the air supply hose.
5.Connect the material hose to the pump outlet. Tighten all fittings. Use caution not to damage threads.
