This pump is a double-acting pumping and pumping bidirectional reciprocating pump. The reciprocating pumping of the piston in the cylinder produces two functions of pumping and pressing, which can be pumped and pressed continuously by reciprocating through the valve.

Connect the instrument to be pumped or hose pumped to the hose connector of the cylinder\’s intake or exhaust valve. The connection must be firm to prevent leakage or slipping during use. After connecting the hose, the piston can be pushed back and forth for pumping or pumping.
