Centrifugal Process Pumps
- Applications
- Hot and cold water circulation, Cooling water circulation, Drip irrigation, Water supply and building services, Thermic fluid, Jet dyeing, Volatile fluids, Heat exchanger, Condensate handling, Fire fighting system, Environmental engineering, Marine, Refrigeration and cooling tower installation. Chemical, Petrochemical, Pharmaceutical, Refineries, Steel plants, Sugar, Paper, Laminates industries, Textiles, Rubber, Handling of hydrocarbon, Organic and inorganic chemicals, Demineralised (DM) water, Food industries, Salt plants, Power plants and in industries such as Pulp, Fertilizer and other Process industries. Corrosive and Abrasive process chemicals like Acids, Alkaline, Solvents, Slurries, Crystallizing liquids, Nitric ammonia phosphate, Chemical effluents, etc.
- Features
- Improved efficiency and improved NPSH requirements by the better hydraulic design of impellers (vanes). Low energy costs. Operating costs reduced by trimming the impeller diameter to match the specified duty point. Low vibration level and excellent smooth running characteristics thanks to good suction performance and cavitation free operation across a wide operating range. Casing seal reliably - even in varying operating conditions - by confined casing gasket. Large variety of materials for the perfectly matching pump to the fluid handled. Large range of materials for many applications available as a standard easy to dismantle casing cover and bearing bracket lantern screw are available.
- Volute Casing
- One piece self-venting volute casing design with end suction and top centerline delivery connections. The pump feet are integrally cast into the volute casing. The feet at bottom transfer residual pipe stress shortest possible route to the base plate and foundation.
- Impeller
- Depending on process parameters closed or semi-open impellers are given for NPSH requirements. Hydraulically balanced by back vanes, or in the case of large impeller diameters by balancing holes and wear rings on both sides. Reliable fixing of an impeller on the shaft by impeller nut.
- Shaft Sealing
- Supplied with either gland packing or mechanical seals in a stuffing box with connection for sealing and cooling/flushing liquid. Simple change over from packing to mechanical seal is possible with the aid of standardized conversion kits. Mechanical seal of various makes and seal faces MOC, unbalanced as well as balanced ones can be easily fitted in the standard stuffing box.
- Shaft & Bearings
- The shaft is guided in oil lubricated angular contact and cylindrical roller bearings. The alignment of bearings is ensured by appropriate centering and modern manufacturing methods. The shaft is fully protected from the liquid to be pumped by means of fully enclosed PTFE gasket between the impeller nut-shaft and shaft sleeve. the properly dimensioned shaft exhibits minimum deflection at a stuffing box, resulting in long operational life for mechanical seals.
- Bearing Frame
- The entire range of pump models is covered in just four number of bearing frames. All pumps belonging to a bearing frame have an identical shaft, bearings, shafts sleeves, and impeller fastenings. In addition to standard sight glass, every bearing frame can be equipped with a constant level oiler. For pumping temperature, more than 180°C or 160°C in case of steam jacketed pumps, a lubricating oil cooling circuit can be fitted in the oil pumps bearing frames.
