The reason why cam rotor pumps replace centrifugal pumps

The advantages of cam rotor pumps are reflected in:

① Strong self suction: No need for drainage pump, start directly to complete self suction, pure water can reach 9 meters;

② Forward and reverse: all symmetrical designs, reversible liquid flow, only need to change the driving direction;

③ The ability of gas-liquid mixed transportation: unloading and sweeping of gasoline, diesel, and methanol can be completed by a pump;

The cam rotor pump is simple, and Enron's dry installation has gradually replaced long shaft submerged pumps and self suction centrifugal pumps.
