Hunan PDM Machinery Co., Ltd.

Product Overview: DP Pump is a self Cbalancing multilevel boiler feed pump with single-suction, multievel and sectional structure. This series of pumps are suitbalbe for medium and low pressure boiler water feeding, and high-pressure boiler water feeding for thermal power plant, as well as high-lift water supply and drainage of factories and cities. They are used in transferring water or other liquid with similar physical and chemical properties to water. Temperature of media being transferred can vary from -20~160 Efficient energy-saving: Using advanced hydraulic model, independent R&D energy efficient products. Good centering of impeller and guid vane channel and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improves pump efficincy and pump efficiency is on average 2-5% higher than normal DG pump. New structure: With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without the balcancing disc structure. New technology: Unique throttling and pressure reduction devices, odd-lecel balancing device. High reliability: By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced. Low maintenance cost and long life time By adopting precision casting and unique throttling and pressure reducing devices for auxiliary support, pump vibration and noise are greatly reduced and service life is prolonged.

Features: 1. New-pattern, air-cooled, 4-stroke gasoline engine powered 2. High strength die-cast aluminium alloy pump body 3. Compact structure, light weight for easy transportation 4. Security operation and easy maintenance. We can maufacture the goods by your special demand The color of goods looks can be choosed by the customers.

With short gaps in the both ends of support, XS type pump works stably with less noise and vibration. It can be risen speed operation to meet wider usage. Being inlet and outlet located in the same center line, the pipelines arrangement looks simple and beautiful. The rotor can be operated in reverse direction to avoid damage to the pumps from water hammer. Unique design of high temperature, using middle support, thickening pump casing, seal cooling and oil lubrication bearing make XS type pump suitable for working at 200, especially for heat supply newtwork requirements. XS type pump case body can be vertically or horizontally installation acoording to different working condition, with mechanical seals or packing seals. Wtih industrial designs to the shape of XS type pump, the line of pump is clear and beautiful to in line with modern aesthetics. Cost advantage: 1. Using the advanced hydraulic model, the efficiency of XS pump is 2%~3% higher than the same type pumps. The operating cost minimum. 2. The vacuum height of XS type pump is risen 1-3 meter to reduce land construction investment and to extend the service life. 3. Using inport brand bearing, such as SKF, NSK and using various pump material make XS type pump suitable for any site working condition and minimize the maintenance cost. Maintenance advantage: 1. With container type mechanical seal, the mechanical seal of pump is very easy and simple to replace. 2. With elastic ripess assembling, the rotor parts is easy and rapid to assembly and disassembly. 3. It is unnecessary to make adjustment to any gap when assembling.
