The south india general agencies, a chennai-based organisation manufactures supplies self-priming high performance stainless steel pumps - tullu80ac. These stainless steel pumps are provided , with pump chambers and impellers which are manufactured from made of ss-304 grade stainless steel. Following are some hardware features of these stainless steel pumps which include: these steel pumps are constructed without air release cock since the suction and delivery passage of the pump are placed at the top. Dynamically balanced rotating parts assure llonger life and low noise are assured by dynamically balanced rotating parts . Larger suction and delivery pipe connections minimise losses in pipe and the sealed ball bearings protect the bearings form dust and corrosion. . The motor of the pump is totally enclosed and fan cooled. There are some technical features of these stainless steel pumps include: the length of the pumps is 270 mm and its weight is 9.300 kg. Both the suction and delivery nozzles are of 13 m/m. These steel pumps will not end up with rusting and jamming problem. These can be placed in any position, i e horizontal or tilted. The washer, circlip and woodruff key of the pump assembly are made of ss-316. Inner packing of chambers are manufactured from is made of teflon and the rubber part of seal is made of viton.Some of the chemicals to which these pumps have resistance are ammonia [aqueous], barium carbonate, calcium hydroxide, copper nitrate, boric acid and calcium carbonate. Some general specifications of these pumps are: the specifications of these pumps are as follows:* drive: 0.37 kw * voltage: 220/230 volt ac * speed: 2,850 rpm * current: 2.6 amp [max] * condenser: 10 mfd capacitor [start and run] * power consumption: 525 watts * insulation: class `b`
