4. and rob the pump of its effective displacement This will not cause noisy operation but will reduce the pump capacity and may show up as a drop in pressure when the discharge is open Water may accumulate in the pump crankcase from two sources the most prevalent being leakage of the cups as explained in paragraph 7 The other means of accumulation being a condensation of moisture inside the crankcase due to changes in weather or the repeated heating and cooling of the pump due to its normal usage Pumps that are used rather consistently and run for a considerable period of time to heat the oil and other working parts will not normally accumulate water by condensation If the cups are replaced as soon as it starts to leak it will be impossible for water to enter the crankcase from this cause Worn connecting link bearings will only develop because of unusual or adverse operating conditions They will however be seriously affected by corro sion if water is present in the crankcase and they will wear out from overheating if the oil is not clean and of good quality For this reason we recommend thorough draining cleaning and refilling with new oil at the specified interval and prior to any storage period Replace link inserts as soon as any wear is noticed to avoid damage to crankshaft journals Also see paragraph 17 and lubrication instructions 26850A003 CALL 1 800 577 8111 FOR SALES AND SUPPORT 12 Lack of sufficient oil in
5. crankcase can quickly cause failure of pump power end and result in extensive repairs Oil level should be checked periodically during normal operation as well as when maintenance work of any nature is performed Insufficient oil will first be indicated by excessive heat and should be corrected immediately 13 A foaming mixture will sometimes have the same effect as a small air leak in the suction line This is because various quantities of the foam are drawn through the suction line into the pump disrupting the normal flow of water 14 Pressure regulators may become sluggish in action due to the plunger sticking or fitting too tightly in its cylinder This condition may be caused by an accumulation of chemicals collecting in and around the plunger or may be due to excessive corrosion of the plunger parts To check this condition remove and clean the plunger After cleaning the plunger parts should be covered with a waterproof grease before assembling In some cases there is a tendency for the pressure regulator to chatter or vibrate excessively This is an indication of unstable operation due to nozzling in the high or low capacity range of the regulator the nozzling requirements should be at least 5096 and not exceed 90 of pump capacity Due to nozzle wear the system requirements may exceed the 90 limit resulting in cycling or ham mering of the regulator This can readily be checked by replacing the worn nozzle 15 If a

7. large piece of foreign matter becomes lodged between a pump valve and valve seat or if some thing of this kind becomes wedged in so that it prevents the valve from operating normally we can expect a drastic drop in capacity and considerable surge or pulsation will be noticed in the discharge line To correct a condition of this kind it is usually necessary to examine each valve in the pump until the offending condition is located The use of clean liquid and seeing that the suction strainer is in proper condition will prevent trouble of this kind 16 Noisy pump operation will sometimes be caused by a piston rod being loose in the crosshead This will only become evident after the rod becomes so extremely loose that some end motion can be found between the rod and crosshead A noise of this kind usually has a regular cadence timed with each stroke When this condition occurs it is always necessary to replace both the rod and the cross head 17 More than the recommended amount of preload to the crankshaft bearings will reduce bearing life require more power and generate more heat Less than the recommended 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 Worn roller bearings will continue to run for a long time but will introduce wear particles into the oil which can cause other damage may cause overheating and may or may
8. not cause a notice able noise Check oil regularly check for wear particles when changing oil UNUSUAL CONDITIONS WHICH MAY CAUSE TROUBLE Pinion shaft breakage on the drive side of the pump may be caused by having the pulley or sprocket positioned too far away from the pump bearing It may also be caused by a loose drive chain if the pump is chain driven If the V belts have a tendency to wear rapidly it may be due to having the belt tightener pulley adjusted too far into the belt throwing a reverse bend in the belt where it passes over the pulley If very much reverse angle seems necessary to keep the belt tight other provi sions should be made for tightening such as placing shims under the pump base or otherwise spreading the drive centers enough to take up the belt length On multiple V belt drives a complete set of belts should be installed when making a replacement Further all the belts in one set should be checked for length and accurately matched to avoid placing an undue load on any one belt F E Myers 1101 Myers Parkway Ashland Ohio 44805 1969 419 289 1144 FAX 419 289 6658 www femyers com Myers Canada 269 Trillium Drive Kitchener Ontario N2G 4W5 519 748 5470 FAX 519 748 2553 26850A003 CALL 1 800 577 8111 FOR SALES AND SUPPORT ATEAWASSY IV3HSSIISO C NIT LSIAM Nid ONIavadG NIvad ON 1d KEES E A382Ss CZ DNTISi Des 3D5vn5iog fiel et LN3A 3 ddIN e8 dv3 eg J

23. inder body such as might be caused by freezing if the pump is not properly drained in freezing weather There is also a definite possibility of air drawing past the packing on the suction stroke if the packing is badly worn If the pressure regulator internal bypass valve is badly 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 that the valve is badly worn and should be replaced or that something is lodged under the valve holding it open A broken pump valve or spring will often prevent one cylinder from functioning properly Very rough pulsing discharge a knocking sound and a loss of capacity will result If not repaired promptly the rough running pump can cause mechanical damage to itself or other system components Badly worn piston cups or valves and valve seats will cause a serious drop in pump capacity This will be indicated by a drop in pressure when guns are turned on Worn piston cups are very easy to detect because of the water leakage The piston cup should be replaced just as soon as this leakage is noticed If it is allowed to continue some of the water may work past the piston rod seals into the pump crankcase Water in the pump crankcase will cause severe cor

27. rosion of the bearings causing rapid wear Worn valves can only be detected by visual examination of each valve assembly The most prevalent cause of valve wear is the use of highly abrasive liquids which will cause the valve and valve seat to wire cut The cut starts as a very small groove but increases very rapidly once the valve starts to leak through this groove If the valves 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 and keep the cost of replacement parts to a minimum If a portion of the pump delivery is allowed to bypass because the 1 control valve is not com pletely closed there may not be adequate flow to develop full pressure This also will cause rapid wear in the control valve any excess flow should be bypassed only by the pressure regulator Pump cylinder bodies must withstand an extreme amount of shock and pulsation while the pump is in operation If the pump is allowed to freeze due to not being drained the freezing may crack the cylinder body walls in almost any location If the crack should occur 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
28. sediment chamber should be installed in the suction line between the gate valve and the pump suction The strainers in these sediment chambers are of more than adequate capacity to allow a free flow of the liquid to the pump However because of its normal function of collecting sediment the strainer may become severely clogged and in some cases it will completely stop the flow of liquid to the pump The length of time the pump may operate before it is necessary to clean the strainer will depend upon the type of liquid pumped After the pump has been used a short period the operator will soon become familiar with the amount of running time between strainer cleanings 26850A003 CALL 1 800 577 8111 FOR SALES AND SUPPORT 4 Any piston pump when operated at high pressure will not operate satisfactorily or quietly if a mixture of air and water is allowed to enter the pump suction For this reason a small air leak in the suction line will cause the pump to knock and vibrate excessively This holds true only for a small air leak which allows 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 or by a crack in the suction wall of the cyl

30. to prime the pump to get the pumping action started Priming will be required under conditions where it is impossible for the piston to displace the air in the pump and replace it with water This could be caused by a high suction lift high from the water supply to the pump the valves being stuck on the seat such as after pumping a sticky fluid or it might be caused by valves sticking due to extreme corrosion of the valves and seats 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 When the pump appears to need priming this condition can be checked by pouring water into the cylinder body through one of the valve cap openings or into the pump discharge opening at the same time operating the pump to work the water into the cylinder and valve passages Frequently a gate valve is installed in the suction line between a tank or pressure line and pump sediment chamber This valve is usually installed in the line to shut off the supply source for cleaning sediment chamber or for pump repairs 11 If this valve is closed or even partially closed it will interfere with the flow of water to the pump suction to such an extent that the pump will not perform to full capacity If the valve is partially closed it may cause severe knocking and vibration of the pump because the water cannot flow into the cylinder cavities fast enough A
