Installation (All Pumps) Typical Installation Z Y The Typical Installations shown in Figs. 2 and 3, and the following installation information are only guides. Proper sizing of the pump, accessories and lines is essential to get the maximum performance from your system. Contact your Graco distributor for assistance in designing a system to meet your needs. Mount the Pump This pump can be mounted on a floor stand, cart, wall bracket, or drum. The floor stand shown in the Typical Installation is Part. No.
Installation (Air-Powered Pumps) Air Line to Motor WARNING A bleed-type master air valve (D) is required in your system, to help reduce the risk of serious injury including splashing fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump. The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump. Order Part No.

Installation (Hydraulic-Powered Pumps) Hydraulic Power Supply CAUTION The Hydraulic Power Supply must be kept clean at all times to avoid damage to the motor and hydraulic power supply. 1. Blow out hydraulic lines with air and flush thoroughly before connection to the motor. 2. Plug hydraulic inlets, outlets, and line ends when disconnecting them for any reason. 1. Be sure the power supply can provide sufficient power to the motor. 2.

Operation (All Pumps) Before You Start the Pump 1. Shut off the power to the pump. Read and follow all instruction manuals, labels and tags supplied with this pump and with all the accessories you add to the system, before operating the system. 2. In an air-powered system, close the air regulator and close the bleed-type master air valve. Flush the Pump Before First Use The pump was tested in lightweight oil. If the oil will contaminate the fluid you are pumping, flush it out with a compatible solvent.
Operation (Air-Powered Pumps) Starting and Adjusting the Pump 1. Charge the surge tank, if you are using one. See the separate instruction manual, 307–707. 2. Open all shutoff valves (D). 3. Open the dispensing valve/spray gun at the last gun station and keep it open while starting the pump. 4. Open the bleed-type master air valves (M). 5. Adjust the air regulator (L) to the minimum pressure necessary for the pump to cycle slowly. 6. When fluid is flowing smoothly from the gun, release the gun trigger. 7.
Operation (Hydraulic-Powered Pumps) Starting and Adjusting the Pump 1. Charge the surge tank, if you are using one. See the separate instruction manual, 307–707. 2. Open all shutoff valves (D). 3. Turn on the hydraulic power supply. 4. Open the flow control valve (S) all the way. 12. Release the gun trigger. NOTE: In a circulating system, the pump operates continuously until the power supply is shut off.
Maintenance The operating conditions of your particular system determine how often maintenance is required. Establish a good maintenance schedule during the first several weeks of operation by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Your maintenance schedule should include the following: Excessive Leaking at Throat To monitor leaking at the throat, remove one of the small plugs (31) from the packing nut (21).
Maintenance Air Line Lubricator Keep properly filled for automatic air motor lubrication. Air Line Filter Drain and clean as necessary. Hydraulic Power Supply Check Carefully follow the hydraulic power supply manufacturer’s recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Mix Tank Volume Don’t let the mix tank run dry. When the tank is empty, the pump demands more power as it tries to suck in some fluid.
Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 12. 1. Relieve the pressure. 2. Check all possible problems and solutions before disassembling pump. PROBLEM CAUSE SOLUTION Pump output low on both strokes. Restricted air or hydraulic supply lines. Clear any obstructions; be sure all shutoff valves are open; increase pressure, but do not exceed maximum working pressure.
Service Disconnecting the Displacement Pump NOTE: In stand or wall-mounted installations, you do not have to remove the entire pump from its mounting. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 12. 1. Relieve the pressure. 2. Disconnect the hoses from the displacement pump and plug the ends to prevent fluid contamination. 3.
