Models Models Dura-Flo Pumps with NXT™ Air Motors 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 5 M C D represents the pump (P), pressure ratio (1 5 :1), low noise exhaust motor with DataTrak™ (M), carbon steel construction (C), and 3 ptfe/2 leather packing configuration (D). To order replacement parts, see Parts section starting on page 18.

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 Object being sprayed: follow local code. Solvent pails used when flushing: follow local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity. The equipment must be grounded.
Installation Air Line Accessories For air-powered pumps, install the following accessories in the order shown in FIG. 1, using adapters as necessary. 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. Startup 1. Engage trigger lock. 1. Connect the suction kit (T) to the pump's fluid inlet, and place the tube into the fluid supply. 2. Shutoff the pump: 2.
Operation 5. Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed. Release the gun trigger and lock the trigger safety latch. The pump should stall against pressure when the trigger is released. Do not use your hand or fingers to cover the bleed hole on the underside of the bleeder valve body (AA) when priming the pump. Use a wrench to open and close the bleeder plug (AB). Keep your hands away from the bleed hole. 6.
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 See FIG. 3. Check the wet-cup (AC) daily. Keep the wet-cup 1/3 filled with Graco Throat Seal Liquid (TSL) or compatible solvent.
Troubleshooting Troubleshooting 1. Relieve the pressure, page 12. 2. Check all possible causes and problems before disassembling the pump. Problem Pump fails to operate. 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 socket wrenches Set of adjustable wrenches 24 in. adjustable wrench Torque wrench Thread lubricant Anti-seize lubricant 222955 Loctite® 2760™ or equivalent Disconnect the Lower CAUTION Use at least two people when lifting, moving, or disconnecting the pump. If disconnecting the lower, be sure to securely brace the pump, or have two people hold it while another disconnects it.
Repair Reconnect the Lower 5. Screw the nuts (107) onto the tie rods (106) and torque as noted in FIG. 4. Always use connecting rod adapter 184595 and tie rods 184596 on hydraulic-powered pumps. Other connecting rod adapters and tie rods do not allow sufficient clearance between the drip pan and coupling nut. 1. Screw the connecting rod adapter (105) to the air motor shaft. Torque as noted in FIG. 4. 2. Screw the tie rods (106) into the air motor (101).
