Model And Size of Water Pump Mechanical Seal

Models and sizes of mechanical seals for water pumps

1. Models of mechanical seals for water pumps: Common models of mechanical seals for water pumps include A, B, C, D, E, F, G, H, K and other models. Type A is a single-end seal, which consists of an O-ring, whose inner diameter is the same as the sleeve diameter; Type B is a double-end seal, which consists of two O-rings, one of which has an inner diameter larger than the sleeve diameter, and the other O-ring has an inner diameter smaller than the sleeve diameter: Type C is an integrated seal, which consists of an O-ring and a V-ring, whose inner diameter is the same as the sleeve diameter; Types D, E, F, G, H, and K are split seals, which consist of two O-rings and a V-ring, one of which has an inner diameter larger than the sleeve diameter, and the other O-ring has an inner diameter smaller than the sleeve diameter.

2. Size of mechanical seals for water pumps: The size of mechanical seals for water pumps varies according to different models. For example, the inner diameter of type A mechanical seal is generally 20-200mm and the thickness is 215mm; the inner diameter of type B mechanical seal is generally 10-200mm and the thickness is 225mm; the inner diameter of type C mechanical seal is generally 20-200mm and the thickness is 215mm; the inner diameter of type D, E, F, G, H, K mechanical seal is generally 10-200mm and the thickness is 2-25mm.

A water pump is a machine for conveying liquid or pressurizing liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to convey liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also convey liquids, gas mixtures and liquids containing suspended solids.
