2 HORIZONTAL axially SPLIT volute type, suction and discharge nozzles and supporting feet cast integral with lower half CASING Enclosed balanced impellers are placed back to back to balance axial thrust high tensile steel shaft accurately machined and ground is supported by antifriction bearings. The shaft is protected by shaft sleeves in stuffing box stuffing box can be sealed by gland packing or by mechanical seal and is suitable for liquids having 0temperature up to 90 CDeep groove ball/roller bearings are provided. Standard lubrication is of RotationStandard - Clockwise viewed from driving - Models with reverse rotation are available upon for coupling with electric motors, engines or steam turbines either directly or through belt - Drilling as per depending upon - DIN/ASA with suitable pressure :BS EN 1092 PN 16 (Plain face) or BS EN 1092 PN 25 for DSM 150/52 CONSTRUCTIONAL FEATUREST hese are HORIZONTAL axially SPLIT CASING , two stage single suction PUMPS with HORIZONTAL shaft.

3 Variety of models are available to operate and suitable for 50 Hz and 60 Hz..Highest hydraulic and overall efficiency due to latest design and manufacturing techniquesDouble stage design helps in achieving higher pump NPSHR hence good suction bore design - It helps in keeping the better accuracies in manufacturing and making it vibration free as well as improving the reliability. Hence minimizing the maintenance. High efficiency in wider operating range - The hydraulic designs have been made to get higher efficiencies in wider operating range. This helps in reducing overall operating cost though there is a compromise on the peak efficiencyKirloskar Brothers Limited (KBL) is a leading manufacturer of HORIZONTAL SPLIT case PUMPS .

4 Kirloskar DSM pump series has been introduced in double stage for achieving higher hydraulic efficiencies. Also a thru bore concept in design and manufacturing of these PUMPS for improving the reliability and making it vibration free. Easy maintenance is facilitated by the HORIZONTAL SPLIT case design of the DIMENSIONS / MOUNTING DETAILS DSM (Thru Bore) PumpNotes:-1) All Dimensions are in ) Flanges Drilled to .BS EN 1092 (Plain face) or DSM 150/52 with BS EN 1092 PN 25 PN 16 (FF) (FF)3) Standard Direction of Rotation Clockwise viewed from Driving END DETAILSPUMP 50-20805022522523043016012016105 50-2865502252502454651601201895110135325 806525860252892854120 DSM 50-28 (M)
