See Technical Data, page 20. Flush until clean solvent comes out of hose. 312350E Operation Starting Pump 1. Turn on hydraulic power supply. 2. Open return line shut-off valve (H) first, then slowly open the hydraulic supply shut-off valve (L). 3. Adjust flow control valve (Q) to limit the hydraulic flow to no more than 3 gpm (11 lpm), which is approximately 60 cycles per minute. 4. Adjust pressure reducing valve (N) to increase hydraulic inlet pressure from 50 to 600 psi (0.34 to 4.1 MPa, 3.4 to 41 bar). • Increasing inlet pressure, increases outlet pressure. • Decreasing inlet pressure, decreases outlet pressure. 5. Open drain valve while priming pump. 6. When pump is primed, close drain valve. Always use lowest pressure possible to obtain desired results. This reduces pump wear. If the Pump Leaks at the Fluid Fittings Tighten fittings (1, 5, 60) which are self-sealing and have replaceable o-rings. If leaking persists, change o-rings. sealing fitting (1, 5, 60) reciprocator o-ring (1a, 5a,60a) ti04478 FIG. 4 Shutdown Relieve pressure, page 7, whenever you shutdown. Maximum Working Pressures To reduce the risk of serious injury, including fluid injection and splashing in the eyes or on the skin, which may be caused if a component ruptures: • Never exceed 600 psi (4.1 MPa, 41 bar) Maximum Hydraulic Pressure to the reciprocator. • Never exceed 7500 psi (51 MPa, 517 bar) Maximum Outlet Pressure from the displacement pump. • Accessories added to the pump fluid outlet side should have at least a 7500 psi (51 MPa, 517 bar) Maximum Working Pressure. • Read and understand COMPONENT RUPTURE HAZARD instructions, page 7. 312350E Troubleshooting Troubleshooting Problem Cause Solution Pump does not run. Closed dispense valve. Pump only runs with valve open. Pressure too low. Increase supply pressure using a pressure adjusting valve. Insufficient hydraulic fluid supply. Check hydraulic supply. Adjust to a maximum of 3 gpm (11 lpm) flow. Clogged fluid outlet line, intake valve, dispense valve, suction line. Relieve pressure, page 7. Check. Clear obstructions. Reciprocator damaged. Repair. Pump speeds up or runs erratically. Pump piston and/or intake valve worn. Relieve pressure, page 7. Check and repair. Empty supply container. Refill and repair. Do not allow pump to run dry. Monitor closely or use a low-level cutoff valve. Pump runs but output low on up and/or down stroke. Pump piston and/or intake valve worn. Relieve pressure, page 7. Check and repair. Pump run but output low on both up and down strokes. Insufficient hydraulic fluid supply. Check hydraulic supply. Adjust to maximum 3 gpm (11 lpm) flow. Pressure too low. Increase supply pressure using a pressure adjusting valve. Clogged fluid outlet line, intake valve, dispense valve, suction line. Relieve pressure, page 7. Check. Clear obstructions. Excessive weepage from weep tube Worn throat packings. Repair. (B), page 4. Worn displacement seal. Repair. Hydraulic oil leaks from fittings in the upper or lower reciprocator blocks (31, 32) [Parts page 18]. Fittings 1, 5, 58, (Parts, page 18), are loose, or their o-rings are worn or damaged. Tighten the self-sealing fittings. If leaking persists, change o-rings. 312350E Service Service Use of a hydraulic power supply with fluid temperatures above 154°F (68°C) can create hot surfaces which can burn if touched. • Do not touch pump, motor, or if hydraulic system fluid is above 154°F (68°C). • Allow sufficient time for pump and motor to cool before attempting any service or repair. 32 Replacing Throat Seals See FIG. 5. Replace throat seals if fluid leaks excessively through the weep tube (B), page 4. This procedure can be done without disassembling entire reciprocator. 1. Relieve pressure, page 7. 2. Disconnect reciprocator from pump. 3. Remove four capscrews (15) from bottom of adapter (43). Tap adapter to loosen it and pull it off the bottom cap (32). 4. Remove seal (44, included in Reciprocator Repair Kit 247455) from top of adapter (43). 5. Install seal (16) in adapter (43) in the order shown in FIG. 5. 6. Reassemble.

Flush pump if possible and stop it with displacement rod in lowest position. 2. Relieve pressure, page 7. 3. Disconnect outlet hose from displacement pump. 4. Slowly loosen hydraulic supply (60) and return (5) fittings to relieve any pressure. Then remove hoses. 5. Install plugs on tube fittings and in hose ends. 6. Check o-rings (5a and 60a) on fittings and replace them if they are worn or damaged. See FIG. 4 and Reciprocator parts drawing, page 18. 7.
