Diving Pumps
 

A collection of hand operated divers air pumps. These pumps were meant to be used in warm shallow water.

   

 

Morse #15 shallow water divers air pump

 

 

The Diving Machines collection of mid-1900's hand-operated American shallow water hard hat diver's pumps include the Morse #15, Miller Dunn and Diving Equipment & Supply Co. systems. These heavy all brass pumps have two reciprocating cylinders mounted astride a vertical or horizontal support with pivoting rocker arms. A steel handle used at the top of the rocker is pushed back and forth actuating the leather ringed piston plungers forcing air up through a non-return check valve and on to the diver's helmet.

The New York made Snead two-stage pump provided a higher pressure than most equal cylinder-sized lever pumps. Air from the larger cylinder was compressed down it into a smaller cylinder providing even a greater out pressure for higher pressure applications.
