Piston pumps work to reduce a volume by a fixed crank-driven piston within a cylinder.
· Reciprocating design for vacuum or pressure
· Lightweight die cast aluminum components or highly wear-resistant plastic
· Balanced for low vibration operation
· Long life, high performance piston seal
With a unitary piston rod, piston is moved up and down with wobbles inside the cylinder as the crankshaft rotates. Then air is moved along with intake and outake valves opening and closing.
