Companies manufacturing large-scale power plant circulating pump, condensate pump large power stations, petrochemical pumps, multistage pumps, sewage pump mud pump, self-balancing multi-stage pump, single-stage double-suction pump, single-stage single-suction centrifugal pumps and other products. Main products which multiple-stage pump, single-stage centrifugal pump, stainless steel multi-stage pumps, fuel pumps, horizontal multistage pumps, double suction pump, self-balancing multi-stage pumps, chemical pumps. ZPMD Mine multistage centrifugal self-balancing is a commonly used in mine drainage horizontal multistage centrifugal pump, ZPDM Mine multistage pump is a new type of multi-stage pump, completely solve the balance disc wear and tear caused by upset. This type of pump inlet is horizontal, vertical arrangement outlet upwards. Are: water segment, the middle, the water segment, the secondary water segment, being the guide vanes, ABM leaves, are the impeller, the anti-impeller, shaft, throttle, pressure relief devices, gear sets, bearing body, the transition tube component parts; the middle of the sealing surface of the wear bars and high-strength bolts out of the water segment joins pump water segment, the middle, the water between segments are made of molybdenum disulfide grease metal hard sealing surface; a rotor mounted on the shaft by positive impeller throttle pressure relief devices, anti-impeller, bushings, bearings and other parts gear sets; bearing a "solid - Tour-style" dry oil lubrication structure, drive end using cylindrical roller bearings, angular contact ball bearings end uses ; Pump Studios by water segment, the middle, the water segment, the secondary water segment, being the guide vanes, ABM leaves, transition tubes and other components; with sealing ring, the guide vane sets between the rotor portion and the fixed portion, etc. seal, when the seal ring should wear sleeve and guide vanes has affected the timely performance of the pump to be replaced. Shaft seal in the form of two mechanical seals and packing seal. When the pump packing, packing ring placed position to be correct, the tightness of the filler must be appropriate, in order to be able to drop by drop liquid oozing appropriate. Pumps installed sealing elements sealed cavity, the cavity must pass a certain pressure of water from the water seal, water cooling and lubrication in water. In the seal equipped with replaceable bushings to protect shaft ZPMD Mine self-balancing multi-stage centrifugal pump works: ZPMD Mine self-balancing multi-stage centrifugal rotary shaft driven by the motor, liquid make power to energy increases, so that the required amount of liquid from the tank via the suction inlet of the pump segment, being the impeller, n guide vanes, the middle of the horizontal section of the water outlet, the transition duct, the secondary inlet section, anti impeller ABM leaves, after the water outlet vertical segments, will send a steady stream of liquid. ZPDM Mine multistage centrifugal pump Model significance: ZPDM120-50x4 ZP- self-balancing DM- mine multistage centrifugal pump design point flow 120- 50- single-stage pump designed head 4- pumps series in the United Pump products sell service areas across the country, across the energy, mining, metallurgy, petroleum, chemicals, building materials, textile, food, shipbuilding, urban construction, marine development and large-scale family farm irrigation, national defense construction. And has sales outlets throughout the country, the company headquarters of a perfect and thoughtful sales and service system, to ensure that the interests of all users.
