METHOD AND APPARATUS FOR CALIBRATING A MULTIPLE PORT PUMP

摘要

A method and apparatus for calibrating a multiple port metering pump includes a graduated scale (152) mounted on the head (10) of the pump and an indicator (200) mounted on the body (12) of the pum p, whereby the angular orientation of a plurality of radially extending, sequentially spaced outlet ports (94, 96) may be adjusted relative to the pump piston (52) to calibrate and balance the flow of fluid therethrough.
