M7N SERIES MECHANICAL SEAL, suitable for clean water, sewage, oil and other medium corrosive media, widely used, strong interchangeability, compact structure, push ring by the transmission tower sub-card, prevent spring fall off. Reliable performance, widely used in petrochemical pumps. This series of mechanical seals are generally used under low pressure conditions. The elastic compensation element of this series of mechanical seals is the waveform spring, which has the advantages of short axial size, strong resistance to blockage, and resistance to elastic failure. Generally applicable to the conditions containing solid particles. The elastic compensation element of the M74 series mechanical seal is a small spring, the elastic source side is exerted by a number of small springs together, its advantage is uniform force on the sealing surface. The F of M7F and M74F series mechanical seal refers to the spiral groove structure of the outer circle processing of the spring seat. Its role is to accelerate the flow of liquid by pumping the spiral effect, so as to reduce material accumulation, and is also beneficial to the rapid cooling of the seal. The driving mode of M7S2 and M74S2 series mechanical seals is deeply dependent on the key drive, and the key drive can be used when the axle diameter is more than 100mm, and its function is to drive more reliably.
