Water. desalination + reuse June 2017 Tech Quarterly 23 T Q : P U M P S Torishima Pump Mfg. Co., Ltd. Torishima has supplied a wide range of pumps for various applications in RO MSF and MED plants over the last 40 years. There are now over 2,000 pumps operating in desalination plants in 20 countries around the world. Pump Applications for RO • Seawater Intake & Filtered Water Pumps • High Pressure Pumps • ERD Booster Pumps • 2nd Pass Feed & Back Wash & Flushing Pumps • Potable Water Pumps Performance Range for HP pumps for RO Capacity : 200 to 3,000 m 3 /h Pressure : up to 80 bar HP pumps for middle range of RO feed water, MHH The MHH range of pumps has three or more stages and has an axially split casing construction. Thrust forces are compensated by a hydraulic balancing device. MHH features Capacity : 700 to 1,400 m 3 /h Pressure: 40 to 80 bar Speed: 50Hz-2P (VFD operation available), 60Hz-2P Discharge Size: 250 to 300 mm MHH benefits • High pump efficiency and good suction performance are realized by optimum hydraulic design using fluid analysis technology. • Low vibration is achieved by advanced structural design technology. • Horizontal axially split casing enables easy inspection and maintenance. • Cartridge mechanical seals allow for easy maintenance. • Balancing disc and seat mechanism is adopted for axial thrust equilibrium. • Radial thrust is supported by plain bearings. • Fan air cooling is standard for cooling the main journal bearings. Water cooling is also available as an option. No forced lubrication system is required.
