　　Hunan High Temperature Resistant Boiler Feed Pump, High Temperature Resistant Boiler Feed Pump Manufacturer, 30 Years of Boiler Feed Pump Factory, Zhongda Pump Industry

　　Hunan Zhongda Energy saving Pump Industry Co., Ltd. produces a series of clean water pumps, including ZD type high-efficiency energy-saving self balancing multi-stage pumps, D-type series multi-stage pumps, S-type series double suction pumps, DG type series boiler feed pumps, R-type high-temperature hot water pumps, IH series chemical pumps, etc. Customers are welcome to inquire!

　　This series of pumps is a horizontal single suction multi-stage segmented centrifugal pump, and the hydraulic model of the high-efficiency energy-saving product used is in a technical priority position in the industry. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, and easy installation and maintenance.

　　It can be used for conveying water without solid particles (abrasives), suspended solids, or other liquids with physical and chemical properties similar to water.

　　Our company has passed the IS09001:2000 quality system certification, and our product design, production, and service have strict and standardized control systems, ensuring sufficient product quality assurance.

　　DG type: used for conveying clean water or liquid with physical and chemical properties similar to water pumps that do not contain solid particles and have a temperature below 105 ℃. It is suitable for small boiler feedwater or conveying hot water or media similar to hot water.

　　In addition, our company can achieve the structure and function of multiple outlets for this series of pumps according to user needs.

　　Structure of DG120-130 * 11 high-temperature boiler feed pump:

　　This type of pump is a single shell, single suction, multi-stage segmented centrifugal pump structure. The inlet of the pump is vertical, and the outlet is vertically upward. The specific structure is as follows:

　　2.1 Stator section

　　Mainly composed of front section, middle section, guide vanes, rear section, bearing frame, and balance chamber cover, which are connected by threaded bars and nuts. The two sides of the front and rear sections are fixed on the pump seat with bolts and nuts

　　2.2 Rotor components

　　The main components of the impeller, impeller sleeve, balance sleeve, balance disk, and shaft sleeve are tightened with small round nuts and fixed on the shaft using flat keys to prevent rotation. The entire rotor is supported on bearings at both ends. The rotor is directly connected to the motor using an elastic pin coupling.

　　To compensate for expansion, a toothed pad is installed between the rear stage and the balance sleeve, which should be replaced during pump maintenance.

　　2.3 Balance mechanism

　　This pump adopts a balance plate hydraulic balance device that can fully and automatically balance axial force. The device consists of four parts: balance plate, balance plate, balance sleeve, and balance stop sleeve.

　　High temperature boiler feed pump, Hunan boiler feed pump, 30-year boiler feed pump factory, Zhongda Pump Industry:

　　The material of the overcurrent components of the pump is cast iron, and the material of the shaft is 45 steel.

　　High temperature boiler feed pump, Hunan boiler feed pump, 30-year boiler feed pump factory, Zhongda Pump Industry:

　　The DG120-130 * 11 pump is installed horizontally. Except for the D16-60 pump, which has a vertical upward suction direction, the suction direction of all other pumps is horizontal. The outlet direction of all D-type pumps is vertically upward. The axial force is balanced by a balance plate. Shaft seals generally use packing seals, and mechanical seals can also be used according to user needs. Except for D85-67 and D155-67 pumps, which use sliding bearings and thin oil lubrication, the rest use rolling bearings and grease lubrication.

　　DG120-130 * 11 complete set scope:

　　The pump is matched with the motor and base, and can be equipped with a functional base or its own base. The manufacturer also provides accessories (including discharge cone tube, gate valve, bottom valve, check valve) and spare parts (including impeller, sealing ring, guide vane sleeve, balance disc, shaft sleeve).
