Do this with the pressure release valve open so the pump operates at no pressure Noisy pump operation can be caused by a loose plunger rod in the crosshead This noise usually has a regular cadence timed with each stroke of the plunger When this occurs always replace both the rod and the crosshead Increased preload to the crankshaft bearings will reduce bearing life require more power and generate more heat while insufficient preload may cause a knock timed with the crankshaft rotation Check for loose bolts on the crankshaft end caps or adjust shims to obtain proper bearing preload 26850A005 10 08 14 MODELS C25 25DV H D amp C35 20DV H D Rew 2 OW 5 SES om 5 56 Nit 2 8 FN 5 A 7 2 2 An WY 22725 28 26850 005 10 08 14 6 MODELS C25 25DV H D amp C35 20DV H D PARTS LIST FLUID END Description SEAT VALVE 06125A002 POWER END Description SPRING RETAINER 06120A000 VALVE 17714 003 RETAINER OIL SEAL HOUSING 24958A001 SPRING VALVE 31 32 1 0 x 1 LG x 6 COILS SUCTION 06127A002 HOUSING OIL SEAL 24959A002 SCREW 10 32 UNF x 1 2 06106A034 SPRING VALVE 31 32 1 0 x 1 LG x 5 COILS DISCH 06127A003 GASKET VELLUMOID 2 15

20. or quietly if a mixture of air and water is allowed to enter the pump suction A small air leak in the suction line will cause the pump to knock and vibrate excessively by allowing the pump to draw a certain amount of water mixed with air on each stroke of the piston A large air leak will cause the pump to lose prime after which it cannot be reprimed until the air leak is stopped Air leaks may occur at the joints of the suction line piping at the gate valve in the suction line at the gasket sealing the cap on the sediment chamber by crack in the suction wall of the cylinder body or by air drawing past the packing on the suction stroke if the packing is badly worn If the pressure regulator internal bypass valve is worn it will allow too much of the pump capacity to be bypassed and recirculated back to the tank By examining the flow from this valve with the discharge turned on it can be determined whether or not the valve is worn If a heavy flow continues when the discharge is turned on it is usually a good indication of a worn valve and should be replaced Worn plunger cups valves or valve seats will cause a severe drop in pump capacity pressure Worn plunger cups are detected by water leakage past the cups and should be replaced immediately Water getting into the pump crankcase will cause severe corrosion of the bearings Worn valves can only be detected by visual examination of each valve assembly Abrasive liquid will cau
21. se wire cuts which begin as a very small groove but increase rapidly once the valve starts to leak through this groove If the valve plates are replaced as soon as they start to show this cutting action it will prevent the valve seat from becoming cut in a similar manner Pump cylinder bodies withstand an extreme amount of shock and pulsation while in operation but if the pump is allowed to freeze by not being drained the freezing may crack the cylinder body walls in almost any location If the crack occurs on the suction valve or cylinder portion of the body it may allow a small amount of air to enter on the suction stroke and cause noisy operation or a decrease in pumping capacity If the crack develops in the walls between the cylinder cavities or discharge valve cavity it may allow the water to flow from one cavity to the adjacent cavity and cause uneven displacement The holes in the gun or nozzle discs are continually subject to wear because of the high velocity of the liquid through the holes If the holes become worn they may allow a higher rate of discharge than the pump is able to provide then a drop in pressure will be noticed This can quickly be checked by reducing the number of nozzles or guns while watching the amount of overflow from the pressure regulator If there is considerable overflow it is an indication that the regulator valve is worn rather than the gun or nozzle disc Suction surge arresters should be ins

23. t Pump priming is usually not necessary when the pump is installed correctly However there are certain conditions which may make it necessary to prime the pump to get the pumping action started Priming will be required when it is impossible for the plunger to displace the air in the pump and replace it with water This can be caused by a high suction lift the valves being stuck on the seat or by valves sticking due to extreme corrosion A pump will not prime readily if someone has tampered with the valve springs causing them to exert undue pressure of the valve plates against the valve seats A gate valve is sometimes installed in the suction line between a tank or pressure line and the pump sediment chamber It will shut off the supply source in order to clean the sediment chamber or to perform pump repairs If this valve is partially or fully closed it will interfere with the flow of water to the pump suction This may cause severe knocking and vibration of the pump because the water cannot flow into the cylinder cavities fast enough 26850A005 10 08 14 3 sediment chamber should be installed in the suction line between the gate valve and the pump suction The strainers in the sediment chambers are sufficient to allow a free flow of liquid to the pump If the strainers become severely clogged they will completely stop the flow of liquid to the pump Any plunger pump operating at a high pressure will not perform properly n
