I. Product Overview NL type liquid mud pumps, main components are volute, impeller, pump housing, the pump housing, the support tube, motor base, motor and other components. Volute, pump housing, motor housing, impeller nut is cast iron, good wear resistance, easy processing. The impeller is three-chip single-leaf garden string bending, use a semi-enclosed impeller, and the use of malleable iron, so high strength, wear-resistant; easy to process, through the good, high efficiency. Turning to reduce weight and reduce the amount of high-quality carbon steel shaft is cold-drawn steel park. Pump housings fitted with four oil seal and sleeve to prevent shaft wear and prolong the service life of the shaft. NL mud pump can be vertical or inclined to use, small footprint, volute need to be buried in the working medium, easy to start, without water, from the direction of motor rotation is clockwise tail to see the work. Switchboard length with a variety of specifications for the use of units of local conditions to be selected according to use, another may need to use stainless steel for the transport of corrosive media on request. Second, the product uses 1, NL type submerged slurry pump is single stage single suction centrifugal pumps for use in mining, paper, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petrochemical, chemical, farm, salt, iodine field , dyeing, wine, food, fertilizer, coking plant, construction, marble factory, gold, mud, sand, mud, sewage pond, dirty liquid feed suck thick paste thick liquid, filling and sewage operations suspended material can also be for coal mine drainage and mud containing fluids. 2, if the high pressure pump and water gun, hydraulic mechanized earth work unit, used for ground leveling, dredging in rivers and ponds, drilling and other small water conservancy projects of excavation and losers, and the city's air defense project, raising used with water clear pond fish, pond aeration, etc. Third, the model significance NL (C, F, W) 150A-12 NL: mud pump C: Long F: Stainless Steel W: Horizontal Type 150: water caliber A; Improved mechanical seal A- 12: Lift
