Total solids 3000 ppm. pH value between 6.5 and 8.5 and specific gravity around 1.0. KMF pumps can be offered for liquids having viscosity upto 1000 SSU. These are three / four vane impeller pumps specially designed to pass solid or stingy material. Hand holes are provided in the casing and near the throat of impeller. Pumps are available in Horizontal construction, vertical dry pit or wet pit construction with motor directly mounted on the pump or at an elevation and connected through intermediate shaft. Design Features CASING: Pump casing is high strength cast iron with ample section thickness to produce a large factor of safety over the maximum permissible working pressure. The casing is enclosed by a suction and stuffing box over or head carefully machined to assure perfect alignment. Suction and discharge nozzles and the supporting feet are cast integral with the casing. All flange are drilled according to BS 10 table D. IMPELLER : The impeller of KMF pumps are made of SS 304. The impeller is semi-open type having wide passages into which the liquid flows direct and unimpeded. The impellers are provided with balancing holes for balancing the axial thrust. They are also dynamically balanced to counter the vibrations. Impellers in other materials such as close grained cast iron, Bronze, phosphors bronze Ni-cast iron, cast steel etc. are also available on request.  Bearing Housing Assembly : The rotating assembly is supported on heavy duty bearings mounted in a precision bored frame. Bearing are carefully sealed to exclude moisture and contaminants and retain lubricant. Stuffing Box : Extra deep design and features a gland to simplify replacement of gland packing. Packed stuffing box with lantern ring is the standard arrangement. It is sealed internally. However, against special requirement, sealing by external fluid is also provided. Shaft : Machined from high quality steel, the shaft is sturdy design to minimize deflection and provides long and reliable service. Shaft is protected by sleeve from wear in stuffing box area.    Salient Features   The KMF series are single-stage centrifugal pumps suitable for handling pure or contaminated liquids in large quantity. These pumps are of robust construction and have long working life. These pumps are also low in energy consumption due to very good efficiency. The precision machined pump shaft is seated in amply oil/grease lubricated bearings and protected by a shaft sleeve in the stuffing box area. The integrally cast feet of the casing transmit any forces originating from the pipework directly to the foundation, this means that the rotor is not subjected to any bending stresses and thus optimal working life of the bearings is assured. Electric motors can be used as the prime mover. With diesel engine as the prime-mover, the pump's direction of rotation is anti clockwise from the driven end.   Areas of Application  Cooling Water  Water treatment  Injection and Spray  Condensate  Water supply  Cooling Tower  Storm water and Drainage  Sewage Disposal  HP/LP  Recirculation Construction Material The materials of construction are offered as an example of generally accepted practice, but are not intended as recommendations of fitness for a particular purpose.
