Description

The Yamada air-powered pump is a reciprocating type pump that is driven by compressed air. The pump consists of an air motor section to drive the pump and a lower pump to pump up the material as shown in the Fig. 1 at right. When the compressor feeds compressed air to the air motor, the air piston starts up/down reciprocating motion by means of the function of the built-in air changeover mechanism. This function is transmitted to the piston of the lower pump by the connecting rod that connects the air piston of the air motor to the piston of the lower pump, and gives up/down reciprocating motion to it. The material is pumped into the lower pump by the up/down reciprocating motion of the piston of the lower pump and discharged by pressure from the discharge port.
