GENERAL PUMP 1. INTRODUCTION A member of the Interpump Group This manual describes the use and maintenance instructions of the KS pump, and should be carefully read and understood before pump operation. Correct use and adequate maintenance will guarantee the pumps trouble-free operation for a long time. General Pump declines any responsibility for damage caused by misuse or the non-observance of the instructions indicated in this manual.
GENERAL PUMP A member of the Interpump Group 3.3 Safety of operation The access into the area when a high pressure unit is working should be strictly prohibited to unauthorized personnel. The area should be suitably enclosed and its perimeter, so far as is reasonably practical, cordoned off and proper warning notices displayed in prominent positions.
GENERAL PUMP 4. PUMP IDENTIFICATION KS SERIES A member of the Interpump Group Each pump is fitted with a rating plate (see Fig. 1) containing the following information: 1. Serial number 2. Pump model and version Max RPM Power absorbed Max flow rate (l/min) and pressure (bar) Pump model, pump version and serial number should be specified when ordering spare parts. Should the pump be modified (i.
GENERAL PUMP A member of the Interpump Group 6. DIMENSIONS AND WEIGHT (continued) 7. INFORMATION ABOUT PUMP USE The KS pump has been designed to pump fresh filtered (360 micron max) water at room temperature (1040 F max). 7.1 Water temperature The maximum water temperature allowed is 1040 F. Nonetheless, for short periods of time it is possible to operate the pump with a water temperature of 1400 F. In this case, we advise to contact the Technical or Customer Service Department. 7.2 Max.
GENERAL PUMP A member of the Interpump Group KS SERIES The amount required is: • 5 quarts for versions with the reducer in positions 1 and 4 (see fig. 6). This amount will be slightly lower for positions 2 and 3. • 4.6 quarts for versions without a reducer. IN ANY CASE, OIL MUST BE CHANGED ONCE A YEAR SINCE IT MAY DETERIORATE BY OXIDATION.
GENERAL PUMP A member of the Interpump Group 8. PORTS AND CONNECTIONS KS Series pumps are provided with (fig 4): 1 - 2 inlet ports IN Ø 2” NPT-F Either inlet port can be used; the one not used must be hermetically plugged. 2 - 2 outlet ports OUT Ø 1-1/2” NPT-F 3 - 3 auxiliary ports, 3/4” Gas; used for the pressure gauge only, and for verifying correct priming. KS SERIES The pumps shaft (PTO) must not be rigidly connected to the motor unit.
GENERAL PUMP KS SERIES A member of the Interpump Group 9.3 Version Change A right version pump is defined when: Observing the pump from the head side, the PTO shank of the pump shaft is on the right side. A left version pump is defined when observing the pump from the head side, the PTO shank of the pump shaft is on NOTE: Figures 5 and 5a show right versions. The version may be changed only by specialized and authorized personnel by carefully following the instructions that follow: 1.
GENERAL PUMP A member of the Interpump Group 6. Do not install Venturi tubes or injectors for detergent intake. 7. Avoid the use of standing valves, check valves, or any other type of one-way valves. 8. Do not connect the by-pass line from the valve directly to the pump suction line. 9. Provide appropriate baffle plates inside the tank in order to avoid that water flows coming from both the bypass and feeding lines may create turbulence near the tanks outlet port. 10.

GENERAL PUMP 9.10 V-belt Transmission A member of the Interpump Group KS SERIES A v-belt transmission is allowed only for versions without a reducer unit. For this pump model, we suggest to use 4 XPB belts (16.5 x 13 cogged); only for long durations, use the XPC profile; both the characteristics and the power transmission capacity for each belt can be verified on the diagram in fig.
GENERAL PUMP A member of the Interpump Group KS SERIES 9.11 Transmission Definition To avoid abnormal radial loads on the shaft and its related bearing, please comply with the following indications: a) Use pulleys for v-belts with race dimensions prescribed / recommended by the belt Manufacturer. Should no indications be supplied, please see fig. 9 and the table in fig. 10.
GENERAL PUMP A member of the Interpump Group KS SERIES c) Set belt tension according to the Manufacturer’s specifications; and excessive value will abnormally stress the bearing, reduce its duration and cause premature wear of the pulley. The tension value depends on different variables as indicated in paragraph 9.12. d) Belt length has a natural tolerance ≤ ± 0.75%; for this reason the three belts must be purchased in pairs. e) Follow the belt tension direction as indicated in fig.
GENERAL PUMP A member of the Interpump Group KS SERIES Conclusion: using a dynamometer, by loading the belt with 75 N as indicated in fig. 13, you will obtain a flexion value “te” of about 10.8 mm. Note 1. If not differently indicated by the belt Manufacturer, the inspection of the correct tension value, and the related tension adjustment if needed, is to be carried out after at least 30 minutes of operation in order to obtain belt settling.
GENERAL PUMP A member of the Interpump Group 10. START UP AND RUNNING PROCEDURES 10.1 Preliminary inspections Before start up make sure that the following conditions have been complied with: 1. Suction line should be connected: the pump must never run dry. 2. Suction line must be perfectly air-tight. 3. Any ON-OFF valve in between the pump and water source should be open and make sure the water gets into the pump freely. 4. Make sure all suction/delivery line connections are fully tightened. 5.
GENERAL PUMP A member of the Interpump Group 12. STOPPING THE PUMP FOR LONG PERIODS 12.1 Filling the pump with an anti-corrosion emulsion or anti-freeze solution as in the layout shown in paragraph 9.7 a) Close the filter drain if open. b) Be sure that the connecting pipe is clean and spread with grease, and connect it to the high pressure outlet port. c) Fit a suction hose to the membrane pump. Open the pump suction connection and fit hose between it and the membrane pump.
GENERAL PUMP A member of the Interpump Group 15. TROUBLE SHOOTING THE PUMP DOES NOT PRODUCE ANY NOISE: - The pump is not primed and is running dry! - No water in the inlet line - The valves are blocked - The pressure line is closed and does not allow the air to get out the fluid end. THE PUMP KNOCKS: - Air suction. - Insufficient feeding: - bends, elbows and fittings along the suction line throttle the amount of water which passed through. - too small inlet filter. - dirty inlet filter.
