The suction inlet and impeller outlet of this type of pump are below the axis of the pump shaft, forming a horizontal direction perpendicular to the shaft axis. No disassembly of the inlet and outlet water pipes or the motor is required during maintenance. From the transmission direction, the pump rotates clockwise (can also be rotated counterclockwise as per customer requirement). The main components of the pump include: pump body, pump cover, impeller, shaft, double-suction seal ring, shaft sleeve, etc. The shaft is made of high-quality carbon steel, while the rest of the main components are cast iron.

The pump housing and cover form the impeller's working chamber. On the inlet and outlet water flanges, threaded holes are provided for installing vacuum and pressure gauges. At the bottom of the inlet and outlet flanges, threaded holes for draining are also made. The impeller, which has passed static balance testing, is fixed on the shaft with sleeve and two shaft nuts on both sides, and its axial position can be adjusted by the sleeve nut. The axial force of the impeller is balanced by the blade arrangement and two-way water inlet. The pump shaft is supported by two single-row deep groove ball bearings. The bearings are housed in bearing bodies and mounted at both ends of the pump housing, lubricated with grease. A double-suction seal ring is used to reduce water leakage from the pump's 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, which can also be modified to a mechanical seal according to customer requirements. To prevent air from entering the pump and cool the lubricating seal cavity, a packing ring is installed between the packing. During operation, a small amount of high-pressure water is sealed into the packing cavity through the trapezoidal groove on the pump cover, serving as a water seal.
