Product overview

SOM series is a high-efficiency medium-opening single-stage double-suction centrifugal pump. SOM series double-suction pump adopts linear design and is equipped with reinforcing ribs to make its structure more reasonable, beautiful appearance and stable installation. The short bearing spacing improves the rigidity of the shaft, ensuring the smooth operation of the unit, low vibration and low noise. The fully sealed pump shaft design makes the pump shaft not in contact with the conveying medium, thus ensuring that the pump shaft is not rusted, easy to disassemble and assemble, and has a long service life.
With reliable performance, energy saving, convenient maintenance, long service life and other remarkable characteristics, since the market by users, product design in line with GB/T5657 standard.
Part of the bearing body adopts a middle structure, the pump cover and the upper cover of the bearing body are opened, and the whole rotor can be taken out, which is simple to adjust and convenient to maintain.
There are two kinds of shaft seal structures, mechanical seal and packing seal, and special sealing methods can be used according to user requirements.
The pump body and pump cover are molded with resin sand, which ensures the accurate shape and flow channel size of the casting, smooth surface and improves the hydraulic efficiency.
The pump selects excellent hydraulic model and uses CFD optimization design to improve the hydraulic efficiency of the pump and improve the cavitation performance of the pump.
The finite element method is used to calculate the strength, so that the operation of the pump is more reliable and durable, and the service life of the pump is extended.
Part of the product bearings are water-cooled structure, can be used in high temperature conditions.
The surface of the shaft sleeve can be treated with a special process, or a stainless steel shaft sleeve can be used, which can prevent rust and greatly extend the service life of the machine seal.

Structure Description

The suction inlet and discharge outlet of SOM pump are both below the axial line of the pump. During maintenance, the pump cover can be uncovered to remove all parts without moving the motor and pipeline.
SOM pump is mainly composed of pump body, pump cover, shaft, impeller, seal ring, shaft sleeve, bearing parts and packing seal (or mechanical seal). The shaft is made of high quality carbonThe material of the other parts is basically cast iron. Impeller, seal ring and shaft sleeve are vulnerable parts.
The pump body and the pump cover constitute the working chamber of the impeller, and the inlet and outlet flanges are equipped with pipe screw holes for installing vacuum gauges and pressure gauges. The lower part of the water inlet and outlet flange is equipped with a threaded pipe hole for water discharge.
After static balance test, the impeller is fixed on the shaft with the shaft sleeve and the shaft sleeve nut on both sides, and its axial position can be adjusted by the shaft sleeve nut. The axial force of the impeller is balanced by the symmetrical arrangement of the blades and the water on both sides.
The pump bearings are radial ball bearings. The bearing is installed in the bearing body and at both ends of the pump body, and is lubricated with butter.
The double-suction sealing ring is used to reduce the water leakage of the water pump pressure chamber back to the suction chamber.
The pump is directly driven by an electric motor through an elastic coupling, and can also be driven by an internal combustion engine if necessary.
The shaft seal is a soft packing seal (can also be installed as required). In order to prevent air from entering the pump and cooling the lubrication seal cavity, a packing ring is installed between the packing. When the water pump is working, a small amount of high-pressure water flows into the packing cavity through the trapezoidal groove on the open surface of the pump cover to play the role of water seal.
This product is widely used in urban water supply and drainage, urban water supply, central heating system water supply and drainage, iron and steel metallurgical enterprises, petrochemical refineries, paper mills, oil fields, thermal power plants, airport construction, chemical fiber plants, textile plants, sugar plants, chemical plants, power station water supply; factory, mine fire system water supply, air conditioning system water supply; farmland drainage irrigation and various water conservancy projects.
This product mainly conveys clear water or clear water without solid particles or other media with physical and chemical properties similar to water. By changing the material, sealing structure and method of the over-flow parts, other liquids can also be conveyed. Please contact our company in advance at that time.

SOM series energy efficient double suction pump with intelligent vacuum system:SOM series high-efficiency and energy-saving double suction pump is equipped with intelligent vacuum system, which is used when the pump is installed on suction. The intelligent vacuum system can make the pump's inlet pipeline system always in a full water state, automatically start when there is no water, and automatically shut down when the water is full. Can achieve automatic control, no personnel on duty. There is no need for water diversion measures such as irrigation or vacuuming before each start, no bottom valve, and high intelligence.

SOM high efficiency and energy saving double suction pump product quality credit guarantee standard (AAA level), not only improve the efficiency, but also extend the service life of the unit, improve the overall operation reliability and safety of the equipment, and greatly reduce the life cycle cost.
