Articulating piston pumps work by reduction of a volume using a sealed piston sliding within a cylinder.

	Flow from 35 l/min to 365 l/min
	Pressures up to 175psi
	Oil-less
	Robust
	Long Life

Technical Overview
The articulated piston compressor utilises the same operating principle as a conventional car engine piston. The articulated piston transfers rotational energy from a motor / pulley into a reciprocating motion used to compress air in a cylinder. The rotational motion is transferred through an eccentric and bearing assemble (big end) to the con-rod, on through the wrist pin (little end) to the piston itself.

As the piston moves down inside the cylinder air is drawn in through a one way intake valve, on the upward stroke this air is exhausted through a one way exhaust valve. Sealing of the piston to the cylinder is achieved using two piston rings each backed with a spring to keep them in contact with the cylinder wall. A piston skirt is also used to guide the piston in the cylinder.

The articulated compressor is suited to tough industrial applications that require relatively high flow rates combine with pressure. These compressors are available in AC (single or three phase) or pulley driven, with the smaller sizes also being available in DC.
