Single Stage Double Suction Split Case Pump
SH series and S series is Single Stage Double Suction Split Case Pump, suitable for transporting clean water and non-corrosive (or weakly corrosive) liquids. The maximum allowable temperature of the medium is 80°C. After cooling water is introduced into the bearing bodies at both ends, hot water below 130°C can be transported. Changing the manufacturing materials of the sealing ring, sleeve and impeller can transport muddy water containing mud and sand; changing the manufacturing materials of the pump body and pump cover can increase the inlet pressure of the pump, and can be used in closed cycle situations such as air conditioning and heating. Copper impeller and copper sealing ring for transporting oil.
The shaft seal of the pump adopts soft packing seal, or mechanical seal can be used. Viewed from the direction of the motor, the water inlet of the SH-type water pump is on the left (counterclockwise rotation); the water inlet of the S-type pump is on the right (clockwise rotation). The rotation direction of the pump can be changed according to user requirements.

Product features
1. The Single Stage Double Suction Split Case Pump,structure is compact, the overall rigidity is good, and the operation stability is high;
2. Enhanced overall structure design, shell design pressure rating of 1.6MPa, inlet and outlet flange pressure rating of 2.5MPa, and overall pressure resistance capacity of 2.5MPa. The minimum wall thickness of the shell is 25 mm, and the thickness of the open face of the shell is 60 mm; the double-suction pump produced by other companies in the industry generally has a wall thickness of about 18 and the thickness of the open face is about 35. Therefore, the S pump of our company is one third heavier than the products of other companies for pumps with the same parameters; the operating life can be doubled.
3. In terms of materials: the shell impellers of our products are all cast iron grades of HT250 and are precision cast with resin sand; the sealed shaft sleeve is made of stainless steel; the bearing materials are all imported brands; the sealed flushing tube is made of integral stainless steel, and the top With a flow regulating valve, the amount of flushing water can be adjusted at any time. The pump casing impeller material of other manufacturers in the industry is HT200, which is cast with ordinary clay sand, and the shaft sleeve is 45# steel; the sealing flushing pipe is ordinary steel pipe;
4. In terms of structure, the design structure of our company's S-type pump is completely different from other companies' products: ordinary double-suction pumps are the pump body, pump cover, impeller, shaft sleeve, shaft, and bearing body parts on both sides; we The S pump is designed with an independent part between the pump body and the cover: the sealing body; when the pump is used for a long time and the sealing cavity is worn out, there is no need to replace the pump body, only the sealing body needs to be replaced, which reduces operating costs.
5. The pump shaft is designed with high reliability, and the strength level is increased by one level. The left and right bearing bodies are common, which reduces the order types of spare parts in the future and is convenient for management. Moreover, when designing, there are temperature measuring devices on the bearing bodies on both sides, which can monitor the temperature of the pump bearings at any time.
6. High efficiency: The hydraulic models of the impeller and shell of our company's products are all imported from abroad, and the actual operating efficiency is 3-5% higher than other similar products. Many users have achieved good energy-saving effects after actual use.
At present, there are many companies in the water pump industry that produce double-suction pumps, but the technical content is indeed very different; the commonly used S-type pumps are all technology in the 1960s, with backward structure, low efficiency and poor reliability; our company's S-type products are designed with a high starting point. No matter the structure, material configuration, efficiency and operational reliability are unmatched by other products.
Product application
Hongar horizontal Single Stage Double Suction Split Case Pump can be used in various fields of applications such as power stations, pulp and paper mills, water and desalination plants. Their construction and design do not only ensure an easy and fast maintenance, but also excellent NPSH values and energy savings. It is used for delivering clear water without solid particles or other liquid which are physically and chemically similar to clear water. The temperature of the liquid is 105℃. Permissible maximum inlet pressure is 0.6MPa.
