Rotary

Rotary pumps are primary based on crankshaft that is moved by rotating of two flywheels attached to it, and situaded on the sides of the pump. Rotary pumps can be built on two and three cylinders Rotary pumps might be operated by at least two man. Pistons attached to the crankshaft pushes in air through the air valves and then through the outlet to an air hose and at last to the diving dress of a diver. Cylinders, air valves and outlet for air are made from brass for the most reliability.

Lever

Lever pumps are primary based on two cylinders, and operated by lifting up and down a heavy beam, with handles attached to its side, and pistons attached to it in the middle.[1][2] Pistons pulls the air in cylinders through the air valves, and then through air hose to the diving dress of the diver. Cylinders, valves and outlet for air are made from brass for the most reliability.[1]
