Model 6000 - postivie displacement pump - cod. produto nv2513

The positive displacement pumps basically consist of a piston and cylinder. the piston is injected into the cylinder thereby displacing an equivalent volume of pump fluid through one of the pump ports. the process can also be reverse to draw fluids into the pump. the seal is made at the piston as it enters the cylinder so the volumetric accuracy of the pump is based on the dimensional control of the pump piston diameter and control of the linear positioning of the piston.
