Product presentation

　　The closed pump is located in the closed cooling water system, the function is to provide cooling water for the auxiliary equipment to ensure the normal operation of the auxiliary equipment and system, and to provide shaft sealing water for the open circulating cooling pump and water chamber vacuum pump.Closed pump non-assembly machine seal is a kind of shaft seal device, which is widely used in the closed pump equipment of thermal power plant.Because the transmission shaft passes through the inside and outside of the equipment, it forms a circular gap between the shaft and the equipment, which causes the medium in the equipment leaking outward through the gap.Therefore, the closed pump non-assembly mechanical seal, can significantly reduce the leakage phenomenon, ensure the stable operation of equipment, and reduce waste and pollution.

　　Applicable scene:

　　The seal is mainly used for the closed cooling water pump in the closed cooling water system of each thermal power plant.

　　Common seal models: JMBF250-470, JMBF350-M9, JMBF300-450 (I), JMBF450KS-60, JMBF163-10
