PLEASE NOTE: THIS EQUIPMENT HAS BEEN DESIGNED TO PROVIDE
RELIABLE SERVICE. HOWEVER BEFORE ATTEMPTING TO INSTALL,
OPERATE OR SERVICE THE EQUIPMENT, THIS INSTRUCTION MANUAL
SHOULD BE READ, UNDERSTOOD AND OBSERVED. FAILURE TO D0 SO
CAN RESULT IN IMPROPER OPERATION WITH POSSIBLY HAZARDOUS
RESULTS.
INTRODUCTION
This book provides installation, operating and maintenance instructions for the Encore
Plunger Metering Pumps; here-in-after referred to as the pump or metering pump. The
pump provides accurate metering and transfer of a wide variety of chemicals. It is
available in four head sizes, four gear ratios, direct or pulley drive configurations and a
single and double simplex configuration. A non-loss-of motion, stroke adjustment is
used to vary the stroke for a more smooth pumping action. Non-loss-of motion is
achieved through the use of a variable eccentric mechanism. Stroke adjustment is done
either manually or with an optional electric stroke lengthpositioner.
An optional variable speed drive controls drive motor speed variations through signals
received from external sources.
When an electric stroke length positioner or variable speed drive is used with the pump,
a separate instruction manual covering the particular equipment used will befurnished.
