Models Models Dura-Flo Pumps with NXT™ Air Motors Part No. Matrix Check your pump’s identification plate (ID) for the 6-digit part number of your pump. Use the following matrix to define the construction of your pump, based on the six digits. For example, Pump Part No. P 1 6 M S E represents the pump (P), pressure ratio (1 6 :1), low noise exhaust motor with DataTrak™ (M), stainless steel construction (S), and 4 leather/1 ptfe packing configuration (E).

Warnings 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 symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode.
Warnings WARNING MOVING PARTS HAZARD Moving parts can pinch or amputate fingers and other body parts. • Keep clear of moving parts. • Do not operate equipment with protective guards or covers removed. • Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
Installation Installation Grounding Flush Before Using Equipment The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. Pump: Use the ground screw (GS) and lockwasher on the motor to attach a 244524 ground wire (Y). Tighten the screw securely. Connect the other end of the ground wire to a true earth ground.
Installation Air Line Accessories For air-powered pumps, install the following accessories in the order shown in FIG. 1, using adapters as necessary. NOTE: Accessory Air Control Kits are available for the NXT Air Motor. The kits include a master air valve (E), air regulator (F), and filter (J). Order the kit separately. See manual 311239 for information. • Bleed-type master air valve (E): required in your system to relieve air trapped between it and the air motor when the valve is closed.

Operation Operation Pressure Relief Procedure Trigger Lock Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. 1. Engage trigger lock. 2. Shutoff the pump: a. For air-powered pumps, close the bleed-type master air valve. b.
Operation Startup 1. Connect the suction kit (T) to the pump's fluid inlet, and place the tube into the fluid supply. 2. Prepare the pump’s power source: a. For air-powered pumps, close the air regulator (F). Open the pump's bleed-type master air valve (E). b. For hydraulic-powered pumps, check the hydraulic fluid level before each use, and add fluid as necessary. Close the supply line shutoff valve (U) and the return line shutoff valve (V). Start the hydraulic power supply. 3.
Maintenance Maintenance Preventive Maintenance Schedule The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Wet-Cups Check the wet-cup daily. Keep the wet-cup 1/3 filled with Graco Throat Seal Liquid (TSL™) or compatible solvent.
Troubleshooting Troubleshooting 1. Relieve the pressure, page 13. 2. Check all possible causes and problems before disassembling the pump. Problem Pump fails to operate. Cause Solution Restricted line or inadequate air/hydraulic supply; closed or clogged valves. Clear; increase air/hydraulic supply. Check that valves are open. Obstructed fluid hose or gun/valve; fluid hose ID is too small. Open, clear*; use hose with larger ID Fluid dried on displacement rod.
Repair Repair Required Tools • • • • • • • • • Set of adjustable wrenches Large pipe wrench 2-5/8 in. wrench Torque wrench Rubber mallet O-ring pick Large vise Thread lubricant Thread sealant Disconnect the Lower 6. To service the lower, refer to manual 308354, supplied. To service the air or hydraulic motor, refer to the separate motor manual, supplied. Reconnect the Lower Always use connecting rod adapter 190287 and tie rods 184596 on hydraulic-powered pumps.
Repair 5. Screw the nuts (107) onto the tie rods (106). Torque as noted in FIG. 3. 6. Screw the coupling nut (103) onto the motor shaft (MS) loosely. Hold the motor shaft flats with a wrench to keep it from turning. Use an adjustable wrench to tighten the coupling nut. Torque as noted in FIG. 3. 7. Tighten the packing nut/wet-cup (PN) as specified in the lower pump manual 308354. 101 8. Reconnect all hoses. Reconnect the ground wire if it was disconnected.
