2 Casing Impeller Gland Shaft Bearing Bracket RANGE APPLICATIONS Delivery size up to mm Capacity up to 0 m /hr Head up to 90 m Max. permissible solid size up to mm, depending on the model consistency up to % QP impellers for more than % consistency For handling liquids with solids in suspension, sludge or pulpy material in Paper Industries, sewage or waste with soft solids in suspension, viscous liquids or liquids carrying fibrous material or powdered material slurries, contaminated process liquids like Sugar factory waste, trade liquors, Water Carrying Gravel, etc. Q impellers for more than % consistency

3 CONSTRUCTIONAL FEATURES SHM are horizontal nonclog pumps having single stage, single suction with back pull out type design. SHS are vertical nonclog pumps for wet pit applications. The pump unit is suspended by a column pipe which also protects the transmission shaft. These pumps can be offered with a column length up to. m. SHV are vertical nonclog pumps for dry pit application in vertical orientation to be driven by vertical flange mounted motor which is directly coupled. Also, SHVT pumps are vertical nonclog pumps for dry pit application in vertical orientation to be driven by vertical flange mounted motor but coupled through transmission shafting. These pumps operate at 0 Hz. Pump Casing : End suction with top centreline delivery as well as horizontal side delivery. High efficiency volute providing smooth unobstructed flow. Delivery flange and feet are cast integral with the casing. A large inspection opening is provided on casing with easily removable cover. Impeller : Single suction type nonclog, free flow impeller dynamically balanced. Enclosed or semiopen impellers are available in code N, P, Q or R. Shafts : In SHM pumps, four driving units cover the entire range. Shaft is supported by two bearings. Shaft in stuffing box area is protected by a shaft sleeve. Axial clearance between semiopen impeller and suction wear plate can be adjusted externally without dismantling the pump. The shaft sleeves under bearing housing and bearing spider are shrunk fitted to shaft in SHS pumps. Stuffing Box : Standard stuffing box is gland packed with grease sealing. Without cooling up to 90 C and with cooling up to 0 C. Mechanical seal option is also available. Bearings : SHM Pumps Standard : Deep groove ball bearings at DE/NDE. Optional : Deep groove ball bearing at DE and roller bearing at NDE. A pair of angular contact ball bearings at DE and one cylindrical roller bearing at NDE. Standard lubrication is grease and optional is oil. SHS Pumps : Intermediate shaft bearing is rubber (For water Lubrication) and bronze bearing (For grease lubrication). Thrust ball bearing in combination with metallic journal bearing at head shaft. Transmission bearings are lubricated with external clear water or grease. Thrust bearings are grease lubricated. Direction Of Rotation : Clockwise viewed from driving end. Drive : These pumps are suitable for coupling with electric motor or engine directly or through belt drives. Flanges : Standard : drilling to DIN ND Optional : drilling to ASA/BS/IS
