Transfer Gear Pumps KF 3/100...KF 6/630

Transfer Gear Pumps KF 3/00...KF 6/630 Construction Plain bearing bush Gear Flange mounting cover Outboard bearing End cover Drive shaft end Shaft end seal Housing Driven shaft pinion Function KF gear pumps are used for pumping a wide variety of fluids. KF gear pumps are distinguished especially by their wide range of variants which are assembled as required on the modular principle and also permit subsequent upgrade. The pumps are also suitable for media with low lubricating properties. The standard housing sections are of grey cast iron. The gear units are manufactured from high strength case hardening steel, hardened and mounted in special multicompound plain bearing bushes. The standard drive shaft is sealed by rotary shaft lip type seal. All pump sizes incorporate helical tooth system. This feature, combined with special gear geometry, results in extremely low noise levels and reduced pressure pulsation. Operating Notes The fluids should ensure a certain minimum lubricating properties, should not contain solids and should be chemically compatible. Avoid dry operation. The pumps may only be operated in the specified direction of rotation, as otherwise the shaft seal will be destroyed. In order to prevent excessive overpressure, a safety valve should be provided in the system or on the pump. The pressure relief valve attached to the pump may only be used as safety valve for short-term operation. To drain off a partial discharge flow over a prolonged period, a separate pressure relief valve with return line must be inserted in the reservoir. A separate pressure relief valve with return line to the reservoir must be foreseen, if a partial discharge flow has to be drained over a prolonged period. 976 4 3 0

Transfer Gear Pumps KF 3/00...KF 6/630 Variants Sealing of the drive shaft: Rotary shaft lip-type seal Double rotary shaft lip-type seal (Quench) Mechanical seal Outboard bearing to take up input drive-side radial load Pressure relief valve for pump and system Uniform discharge flow direction with changing direction of rotation by means of flange-mounting valve combination (universal device). Note The above specified minimum and maximum characteristics are NOT applicable for some specific operating conditions: maximum operating pressure is NOT permissible in conjunction with low speeds and low viscosities. Please contact us whenever such critical ranges are encountered. ATEX We offer numerous transfer gear pumps from the KF3/00... KF6/630 series in ATEX versions. Please ask for our ATEX product catalogue. Special Design To meet your individual requirements on request special constructions are available: for instance mounting flange models, various types of plane bearings, etc. Our Sales engineers will be pleased to advise you. Accessories Direction of Rotation The following should be note for direction of rotation: when looking at the pump shaft end, the direction of pumping is from left to right if the shaft rotates clockwise. when looking at the pump shaft end, the direction of pumping is from right to left if the shaft rotates counterclockwise.

Transfer Gear Pumps KF 3/00...KF 6/630 General The noise optimized pumps of the KF Series are primarily designed for the transport of mediums with an increased share of air, whereby both normal operation and vacuum operation are possible. In applications with no air content in the medium, this type of utilization is not advisale since in such case the noise reduction does not take effect. In these cases, the targeted application of noise reduction elements and also flexible hoses are recommended for achieving noise reduction. Our Sales Engineers are happy to advise you! The following illustrations show the construction of the KF models described on Page 7. Models 96 and 97 are designed for the transport of air-content transmission oils, therefore for application as a lubricating oil pump in ship gears and stationary gears. Special construction measures prevent the otherwise normal noise increase associated with air-content transmission oils and high degrees of negative pressure. The noise levels do not exceed or only negligibly exceed the measurement valued with non-aircontent oils. A shift in the noise spectrum to higher, unpleasant frequencies also does not occur. Pumps with the special code 97 are built as mounted pumps or pumps in combination with an electronic motor. The mounted pump (Fig. ) is equipped with an outboard bearing for the absorption of radial forces like the type that appear when using a floating pinion. The pump in combination with an electronic motor (Fig. ) has no outboard bearing and must be driven by means of a flexible coupling. Mounted pump and electronic motor are sealed at the shaft end by a rotary shaft seal. The pumps with the special code 96 are built as mounted pumps both with (Fig. 3) and without an outboard bearing. This model has no seal at the shaft end, making it possible to operate it with pressure on the suction side. The accruing leakage oil is fed off into the gear space. The pumps with the special code 309 (Fig. 4) are designed for deployment in vacuum facilities for the degassing and cleaning of oils. These pumps are built as pumps in combination with an electronic motor and have no outboard bearing for the absorption of external radial forces. At this version, a triple sealing with quench is used as shaft sealing. The middle shaft sealing is mounted for suction operation.
