Resumen del manual


Do not run pump dry, as permanent damage to the mechanical seal will result. 4. Start the engine, following instructions in the engine manual. 5. With a suction lift of 5 to 10 feet, the pump should discharge liquid within 4 Operating Instructions and Parts Manual Models 020598 and 020599 Operation (continued) one or two minutes. A suction lift of 20 feet can take 5 minutes running time to pick up a prime. If pumping does not start within this time, shut off the engine, let unit cool down about 5 minutes, refill pump casing and retry. If engine does not start, refer to Engine Manual. If pump does not prime after 2 tries, refer to “Troubleshooting Chart” in this manual. 6. Properly fueled and lubricated, the pump/engine unit will run automatically without attention to the controls. The gasoline engine has a built- in governor and will adjust the speed of the engine automatically depending on the volume of water being delivered. Even though this unit will operate with minimal supervision, it should not be left operating by itself. Depending on the application and area unit is operating (high traffic, people in area, etc.) will dictate the necessity of having someone watching over the unit. Maintenance To prevent acciden tal starting always remove spark plug, or disconnect and ground spark plug wire before attempting to service or remove any component. 1. If the pump is located in an area subject to freezing temperature, the pump should be drained when not in operation. Also, the pump should be Performance Chart flushed after each use. 2. Clean the suction line strainer at regular intervals. 3. If the gas engine is equipped with a spark arrestor screen in the muffler, it should be inspected for wear periodically, and replaced when necessary. NOTE: For information pertaining to the engine and engine parts, consult the Engine Manual or contact the nearest authorized service representative or the manufacturer. 4. Periodically check nuts and bolts on engine, mounting frame and pump. Since this is a gas engine pump, vibration levels tend to loosen nuts and bolts faster than normal. Use Loctite (thread sealant) on threads or lockwashers if necessary. MECHANICAL SEAL REPLACEMENT Refer to Figures 1, 2, and 3. IMPORTANT: Replace seal seat, (Ref. No. 22) and seal head (Ref. No. 23) at the same time to ensure proper mating of mechanical seal components! 1. Unthread fasteners (Ref. No. 16), nuts (Ref. No. 25) and remove casing (Ref. No. 15) and casing seal (Ref. No. 7) from adapter (Ref. No. 3). Unthread fasteners (Ref. Nos. 11 and 19) and remove volute (Ref. No. 20) and volute seal (Ref. No. 6) from adapter. 2. Unthread impeller fastener (Ref. No. 10) and remove impeller (Ref. No. 9), impeller seal (Ref. No. 4) and shims (Ref. No. 21). GPH of Water at Total Head in Feet Max.

Pry seal seat from impeller recess with a screwdriver (See Figure 1). Figure 1 – Mechanical Seal Replacement 4. Remove adapter by unthreading adapter fasteners (Ref. No. 5) and fastener seals (Ref. No. 4). Press old seal head and adapter seal (Ref. No. 24) out of adapter by pushing from engine side. 5. Clean adapter and impeller seal recesses before installing new pieces. 6. Carefully wipe polished surface of new seal seat with a clean cloth. 7. Wet rubber portion of seal seat with a light coating of soapy water. 8. Press seal seat squarely into recess in impeller. If seal seat does not press squarely into recess, it can be adjusted by pushing on it with a piece of pipe. Always use a piece of cardboard between pipe and seal seat to avoid scratching lapped, highly polished surface of seal seat (handle it carefully). 9. After seal seat is in place, ensure that it is clean and has not been marred. 10. Using a clean cloth, wipe shaft and make certain that it is completely clean. 11. Place adapter seal (o-ring) onto seal head behind flange and press assembly into adapter as shown in Figure 2. Do not touch or wipe polished face of seal head. Figure 2 – Mechanical Seal Replacement 12. Secure adapter on engine mounting face, using fasteners and fastener seals. Be sure to replace gasket (Ref. No. 31) between engine and adapter, if removed during disassembly. Tighten adapter fasteners evenly to avoid cocking or damaging adapter. 13. Replace impeller and shims, ensuring that key (Ref. No. 8) is in place and lock impeller to shaft with fastener and impeller seal on fastener. 14. Replace volute seal and volute with fasteners, ensure that check valve (Ref. No. 12) is in place then remount casing seal and pump casing with fasten...
