Product Description

★ SOM series are single-stage double-suction centrifugal pumps of split  case type.The pump adopts a linear design with reinforcing ribs,which makes the pump structure more reasonable,  beautiful in appearance and stable in installation.The short bearing distance improves the rigidity of the shaft.ensuring the unit runs smoothly,with little vibration and low  noise.The design of fully sealed pump shaft prevents the pump shaft from contacting with the conveying medium,thereby ensuring that the pump shaft is not rusted,easy to disassemble and assembled,and has a long service life.

★ Our double suction pump series was awarded as high quality and qualified products by the Pump Industry Association.

★ It is suitable for conveying clear water without solid particles or other liquids with physical and chemical properties similar to water. It can be widely used in various fields such as metallurgy, mining, steel, electric power, petroleum, coal, chemical industry and urban water supply and drainage.

★ The SOM range is available in 615 sizes with flow rates of 74-23,500m³/h, heads of 7-306m and bores up to 1600mm.

★ SOM series pumps are characterized by reliable performance.energy saving,convenient maintenance and long service life,and have been favored by users since they were put into the market.

★ Part of the bearing body adopts a split structure.Open the pump cover and the upper cover of the bearing body.and the whole rotor can be taken out.which is easy to adjust and maintain.

★ There are two kinds of shaft seal structures:mechanical seal and packing seal,and special sealing methods can also be used according  to user needs.

★ The frame plate and cover plate are made of resin sand.which ensures the precise shape of the casting and the size of the flow channel.smooth surface,and improves the hydraulic efficiency.

★ The pump adopts an excellent hydraulic model and adopts OFD optimization design. which improves the hydraulic efficiency of the pump and improves the cavitation performance of the pump.

★ The finite element method is used for strength calculation,which makes the operation of the pump more reliable and durable,and  prolongs the service life of the pump.
★ The bearings of some products have water cooling structure.which can be used under high temperature conditions.
★ The surface of the shaft sleeve can be treated with a special process,and the stainless steel shaft sleeve can also be used,which can prevent rust and greatly prolong the service life of the mechanical  seal.

Performance Range

This product mainly transports clear water or other media with physical properties similar to clear water;by changing the material,sealing structure and method of the  flow-passing parts,it can also transport other liquids.Please contact our company in advance.

The temperature of the conveying medium normally used by this product is ≤80°C.If  the temperature of the medium exceeds this value,please contact our company in advance.

Structure Description

The suction port and discharge port of the SOM pump are below the  axis of the pump,and all parts can be dismantled by lifting the pump   cover during maintenance without moving the motor and pipeline.

The SOM pump is mainly composed of pump body.pump cover.shaft,impeller,sealing ring,shaft sleeve,bearing parts and packing seal(or mechanical seal).The material of the shaft is high-quality carbon structural steel,and the material of other parts is basically cast iron.The impeller,sealing ring and shaft sleeve are used  as wearing parts.

The shaft seal of the pump is divided into two types:packing seal and mechanical seal.The packing seal uses lead powder oil impregnated asbestos packing.The packing seal structure is divided into inner water seal packing seal structure and pressure regulating valve packing seal structure.There is a water seal groove on the pump cover of the structural pump,and the high-pressure water at the outlet of the impeller reaches the packing ring through the water seal groove on the pump cover,which acts as a water seal and seal.The pressure regulating valve structure adopts the patented product developed by our factory:water pump pressure regulating valve.The application of this patented product can easily realize the free adjustment of the pressure and flow of the shaft sealing water.The pressure of the water sealing water can be reduced from the highest head of 165m to about 20m,or can be reduced to any required pressure.Ensure that the shaft seal water can achieve the best pressure and flow,reduce the leakage of shaft seal water at the packing.and completely solve the problem of serious leakage of packing structure water seals in the pump industry for many years.and also reduce the shaft power and improve the pump performance.Eficiency,energy saving,and at the same time reduce the wear of packing and shaft sleeve(or shaft).Mechanical seal structure:pumps with small diameters generally adopt split mechanical seals;pumps with large diameters adopt cartridge  mechanical seals.which are convenient for maintenance and  installation.

The user needs to determine the shaft seal method.The packing seal structure and mechanical seal structure of the pressure regulating valve must be specified when ordering,otherwise the supply will be based on the inner water seal packing structure.

As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its characteristics of high lift and large flow. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impeller is merged into a volute.

Double-suction pumps are mainly used in water plants, pumping stations, power stations, air-conditioning circulating water, hot water circulation for heating, industrial water supply systems, fire protection systems, ships, building water supply, irrigation, drainage pumping stations, oil refining industries and other occasions to transport liquids.
