GENERAL PUMP A member of the Interpump Group 7. OPERATING INSTRUCTIONS KT SERIES The KT pump was designed to operate with filtered water (see paragraph 9.7), in environments that are not potentially explosive and at maximum temperature of 1040 F (400 C). Other fluids may be used only upon the approval of The Customer Service Department . 7.1 WaterTemperature The max water temperature is 1040 F (400 C).
GENERAL PUMP A member of the Interpump Group KT SERIES In any case, oil must be changed at least once a year since it may deteriorate by oxidation. For room temperatures that differ from that mentioned earlier, follow the indications contained in the diagram below, keeping in mind that the oil must have a minimum viscosity of 180 cSt. VISCOSITY/ROOM TEMPERATURE DIAGRAM Exhausted oil must be collected in an appropriate recipient and disposed of in appropriate locations.
GENERAL PUMP A member of the Interpump Group 8. PORTS AND CONNECTIONS KT SERIES KT Series pumps are equipped with (see fig. 4): 1. 2 inlet ports “IN”, 1” NPT (KT16A, KT18A, KT20A, KT22A). 2 inlet ports “IN”, 1-1/4” NPT (KT24A, KT28A, KT30A, KT36A, KT36A, KT40A). Line connection to any of the two ports is indifferent for proper pump functioning. The unused ports must be sealed off. 2. 2 outlet ports “OUT”, 1/2” NPT-F (KT16A, KT18A, KT20A, KT22A).
GENERAL PUMP 9. PUMP INSTALLATION A member of the Interpump Group KT SERIES 9.1 Installation The pump must be installed in a horizontal position using the M12x1.5 threaded support feet. Tighten the screws with a torque of 80 Nm (59 Ft-Lb) The base must be perfectly flat and rigid enough as not to allow bending or misalignment on the pump coupling and axis/transmission due to torque transmitted during operation. The unit cannot be fixed ridgedly to the floor.
GENERAL PUMP KT SERIES A member of the Interpump Group 9.2 Direction of rotation The PTO rotation is indicated by an arrow located on the casing near the drive shaft. From a position facing the pump head, the rotation direction will be as in fig. 5. 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.
GENERAL PUMP A member of the Interpump Group KT SERIES 9.4 Hydraulic Connections In order to isolate the system from the vibrations produced by the pump, we advise to build the first section of the duct near the pump (both for intake and delivery) with flexible hose. The consistency of the intake section must be as such to avoid deformation caused by vacuums produced by the pump. 9.5 Pump Power Supply A positive head of at least 8 inches (.2 meters) is required for the best volumetric efficiency. 9.
GENERAL PUMP A member of the Interpump Group 9.7 Filtering On the suction line, install two filters as indicated in fig. 7 and fig. 7/a. KT SERIES With the manual adjustment valve: With a pneumatically activated control valve The filter must be installed as close as possible to the pump, should allow easy inspection and have the following characteristics: 1. Minimum capacity 3 times greater than the pump’s rated flow value. 2. Filter port diameters must not be smaller than the pump inlet ports. 3.
GENERAL PUMP A member of the Interpump Group KT SERIES 9.8 Outlet Line To obtain a correct delivery line, please comply with the following installation instructions: 1. The internal diameter of the hose must allow to guarantee correct fluid speed; see digram in paragraph 9.9 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.
GENERAL PUMP A member of the Interpump Group FOR KT16A, KT18A, KT20A, KT22A: KT SERIES 9.9 Internal Diameter of the Hose Line To determine the internal diameter of the hose, please refer to the following diagram. Suction Hose With a flow rate of ~105 GPM (400 l/mn) and water speed of 1 m/sec. the diagram line that connects the two scales intersects the central scale, indicating the diameters, at a value of ~ 3.5 inch (90 mm). Delivery Hose With a flow rate of ~105 GPM (400 l/mn) and water speed of 5.
GENERAL PUMP A member of the Interpump Group FOR KT24A, KT28A, KT30A, KT32A, , KT36A, KT40A: KT SERIES 9.9 Internal Diameter of the Hose Line To determine the internal diameter of the hose, please refer to the following diagram. Suction Hose With a flow rate of ~105 GPM (400 l/mn) and water speed of 1 m/sec. the diagram line that connects the two scales intersects the central scale, indicating the diameters, at a value of ~ 3.5 inch (90 mm).
GENERAL PUMP A member of the Interpump Group KT SERIES 9.10 V-belt Transmission The pump can be controlled by a v-belt system. For these pumps we recommend use of 3 XPB belts (16.5x13 serrated). Use an XPC profile only for long durations. Both the characteristics and transmissible power of each belt can be verified in the diagram in fig. 7, in relation to the number of RM normally declared by the manufacturer. Minimum duct pulley diameter (on pump shaft): ≥ 6.3” (160 mm).
GENERAL PUMP A member of the Interpump Group KT SERIES Dimensions (in mm) Minimum pulley diameter must be respected. Do not use laminated v-belts. b) Use high performance belts - for example XPB instead of SPB - as a lower quality of belts for the same transmitted power may be necessary and a consequent shorter resulting distance compared to the shaft shoulder (PTO), “a” of fig. 10. Ref 300941 Rev.
GENERAL PUMP A member of the Interpump Group KT SERIES c) Pull the belts according to manufacturer instructions. Excessive pulling can cause reduced bearing life and wear out the pulley prematurely. Pulling depends on different variables as indicated in point 9.12. d) Belt length has a natural tolerance ≥ ± 0.75%. For this reason, the 3 belts must be purchased as a pair. e) Follow the direction of the belt pull as shown in fig. 10; for other needs, contact our Customer Service Department.
GENERAL PUMP A member of the Interpump Group KT SERIES Conclusion: with a wheelbase of 600 mm an with a dynamometer, loading the belt branch with 75 N as indicated in fig. 12, a “te” bend of approximately 10.8 mm is obtained. Note: unless otherwise state by the supplier of he belts, control of proper pull and its relative re-tensioning should be performed after no less than 30 minutes of motion necessary for the normal adjustment of the belts.
GENERAL PUMP A member of the Interpump Group 9.13 Transmission of power from the second PTO KT SERIES Upon request, KT pumps can be supplied with auxiliary PT on the side opposite of the drive (Transmission of power from the second PTO). Transmission can be carried out: • By means of the V belts • By means of the joint By means of the V-belt, withdrawable Max Torque is: 15 ft. lbs (20 Nm) which corresponds to: 4.1 Cv to 1450 RPM 5.
GENERAL PUMP A member of the Interpump Group 10. START-UP AND OPERATION KT SERIES 10.1 Preliminary Inspections Before Start-up Be sure that: The suction line is connected and up to pressure (see Chapter 9) the pump must never run dry. 1. The suction line must be perfectly airtight. 2. All the On-Off valves between the pump and the feeding source are completely open. The delivery line must discharge freely in order to allow the air in the pump to be expulsed easily, thus facilitating pump priming. 3.
