1. The IS water pump is designed according to the performance and dimensions specified in the international standard ISO2858, mainly consisting of the pump body, pump cover, impeller, shaft, sealing ring, shaft sleeve, and suspension bearing.
2. The pump body and pump cover of the IS water pump are divided from the back of the impeller, which is commonly known as the rear opening structure. The advantage of pipeline centrifugal pumps is that they are easy to maintain. During maintenance, the pump body, suction pipeline, discharge pipeline, and motor are not moved. Only the middle connecting piece of the extended coupling needs to be removed to exit the rotor part for maintenance.
3. The casing of the IS water pump (i.e. pump body and pump cover) constitutes the working chamber of the pump. The impeller, shaft, and rolling bearings are the rotors of the pump. The suspension bearing components support the rotor part of the pump, while the rolling bearings are subjected to the radial and axial forces of the pump.
4. The axial sealing ring of the IS clean water pump is composed of a packing gland, packing ring, and packing, etc., to prevent air intake or significant water leakage. If the impeller of the IS water pump is balanced, the cavity containing soft packing is connected to the suction port of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to introduce air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing chamber through the small hole on the pump cover to guide the pressure water in the pump chamber to the packing ring for sealing. If the impeller of the pump does not have a balance hole, there is no leakage problem due to the liquid pressure on the back of the impeller being greater than atmospheric pressure, so the packing ring can be omitted
5. To avoid shaft wear, the IS water pump is equipped with a shaft sleeve protection at the part where the shaft passes through the packing chamber. There is an O-ring seal between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.
6. The transmission method of the IS clean water pump is connected to the motor through an extended elastic coupling, and the rotation direction of the pump, when viewed from the drive end, is clockwise.
7. In order to balance the axial force of the IS clean water pump, most pumps are equipped with sealing rings at the front and rear of the impeller, and balance holes are provided on the rear cover plate of the impeller. Due to the low axial force of some pumps, there are no sealing rings or balance holes on the back of the impeller.
