ZPDG self-balancing multi-stage boiler feed pump in conjunction centrifugal pump is a professional water pumps and other industrial production and sales of integrated enterprise, the company has established a set of rigorous design, development, production and manufacturing to services quality assurance system. 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. Excellent production technology, the establishment of the provincial hydro-mechanical testing the quality assurance system and has passed the ISO9001: 2000 international quality assurance system. The company has a mold shop, foundry, machine shop large pump; in a small pump machine shop, assembly shop, ready to shop, with a strong manufacturing capability. ZPDG self-balancing multi-stage boiler feed pump is mainly used for delivery of solid particles, the temperature of liquid water or physical and chemical properties of -20 ℃ ~ 210 ℃ similar to water. Suitable for medium and low and high pressure water supply. Long life, wear no ring balance disc balance, reducing the balance system wear annoyance. ZPDG self-balancing multi-stage boiler feed pump Model Description: ZPDG85-45 × 8 ZP- DG- self-balancing single-suction, multi-stage boiler feed pump 85- flow (m3 / h) 45- single-stage pump head (m) 8- Pump series ZPDG self-balancing multi-stage boiler feed pump structural forms: the pumps are horizontal multistage centrifugal pump suction vertically upward or horizontally, vertically arranged 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. sealed. The pump is a traditional form of multi-stage centrifugal pump structure innovation, canceled the axial force balance mechanism ,, multistage centrifugal pump is the use of the balance disc or drum balanced structure D, DG-type multi-stage centrifugal best alternatives . Because no balancing device, ie no loss of balance disc friction disc nor balanced reflux losses, so the pump efficiency 5-14% higher than in the same category multistage pumps, while thoroughly address the balance and lead to device failure balance disc and balance disc seat wear or killed by other rotor failure, greatly extend the life of the pump. Overall material and stainless steel pump into two types, the user can choose according to their needs. Vanda 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.
