GENERAL PUMP 1. INTRODUCTION A member of the Interpump Group This manual describes the use and maintenance instructions of the KFM 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 KFM SERIES A member of the Interpump Group 3.3 Safety of Operation (continued) 2. Suction hose should clean and free from obstructions of any kind. The use of a settling tank, where applicable, is recommended. 3. That electrical parts are adequately protected and in perfect condition. 4. That high pressure hoses do not show apparent signs of abrasion, and that fittings are in perfect shape.
GENERAL PUMP 5. TECHNICAL FEATURES MODEL RPM KFM40A 600 KFM SERIES A member of the Interpump Group FLOW RATE GPM 30.0 l/min 113 PRESSURE PSI 1500 Bar 100 Hp 30 POWER kW 22 6. DIMENSIONS AND WEIGHT For dimensions and weight of Standard Version pumps, please refer to fig. 2. Weight: 160 Lbs./69.3 Kg. fig.
GENERAL PUMP A member of the Interpump Group 7.INFORMATION REGARDING PUMP USE The KFM pump has been designed to operate with high percentages of bentonite and/or polymer up to a max. recommended density of 1.05 Kg/lt at max temperature of 1040 F (400 C). Other fluids may be used only upon the approval of The Customer Service Department . KFM SERIES Check the oil level by using the oil level dipstick (1), fig. 3. Refill if needed.
GENERAL PUMP KFM SERIES A member of the Interpump Group 8. PORTS AND CONNECTIONS KFM Series pumps (see fig. 4) are provided with: 1. 2 inlet ports “IN”, 1-1/2”NPT. The line can be connected to either of the two inlet ports: the one not being used must be hermetically sealed. 2. 2 outlet ports “OUT”, 1: NPT. 3. 3 auxiliary ports, 1/2” NPT, used for the pressure gauge only. In case of disassembly, to avoid letting dirt inside the front part of the crankcase, close the threaded hole with the supplied cap.
GENERAL PUMP A member of the Interpump Group 9.3 Version Change and Reducer Positioning 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 is on the left side. See fig. 5 (which shows a right version). The version may be changed only by specialized and authorized personnel by carefully following the instructions in the repair manual.
GENERAL PUMP A member of the Interpump Group 9.7 Delivery Line To obtain a correct delivery line, please comply with the following installation instructions: 1. The internal diameter of the pump must allow to guarantee correct fluid speed; see digram in paragraph 9.8. 2. The first section of the hose connected to the pump must be flexible in order to isolate pump vibrations from the rest of the system. 3. Use high pressure hoses and fittings that guarantee wide safety margins in any working condition. 4.
GENERAL PUMP A member of the Interpump Group 9.9 V-belt Transmission The pump may be driven by a v-belt system. 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 of each belt can be verified on the diagram in fig. 7, in function of the number of rotations normally declared by the Manufacturer. Minimum diameter of the driven pulley (on the pump shaft): ≥ 250 mm.
GENERAL PUMP A member of the Interpump Group 9.11 Definition of belt static tension values Static tension depends on: a) the center distance between the two pulleys (belt length) b) The load due to the belt’s static tension c) The number of belts d) The angle of wrap of the smallest pulley e) Average speed f) Etc. For belts with an XPB profile, the diagram in fig. 11 allows to obtain the valued of the static tension that must be applied vs. the center distance between pulleys.
