bema seals are a type of friction seal or stuffing box used to prevent liquid leakage between the shaft and bearing of compressors or other fluid handling equipment. They are also sealing devices installed to prevent leakage at the pump shaft and housing. Common types of shaft seals include packing seals, mechanical seals, and hydrodynamic seals. The shaft seal of a reciprocating pump is typically a packing seal. When transporting media where leakage is not permitted, diaphragm reciprocating pumps can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly consist of packing seals, mechanical seals, and hydrodynamic seals. bema seal principle: Since between the oil seal and the shaft
