ENCORE® 700 METERING PUMP
INTRODUCTION
This manual provides installation, operating, and maintenance instructions
for the Encore® 700 Diaphragm 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
six head sizes, three gear ratios, direct and pulley drive configurations,
and a single or double simplex configuration. A non-loss-
of-motion
stroke adjustment is used to vary the stroke for a smoother
pumping
action. Non-loss-of-motion is achieved through the use of a
variable
eccentric mechanism. Stroke adjustment is accomplished either
manually or with an optional electric stroke length positioner.
An optional Silicon Control Rectifier (SCR) controls drive motor speed
variations through a signal received from an external source.
When an electric stroke length positioner and/or variable speed drive
is used with the pump, a separate instruction manual for each will be
furnished.
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL IN-
JURY OR DAMAGE TO THE EQUIPMENT, THIS EQUIPMENT
SHOULD BE INSTALLED, OPERATED AND SERVICED ONLY
BY TRAINED, QUALIFIED PERSONNEL WHO ARE THOR-
OUGHLY FAMILIAR WITH THE ENTIRE CONTENTS OF THIS
INSTRUCTION MANUAL. WHEN DEALING WITH HAZARDOUS
MATERIAL IT IS THE RESPONSIBILITY OF THE EQUIPMENT
USER TO OBTAIN AND FOLLOW ALL SAFETY PRECAUTIONS
RECOMMENDED BY THE MATERIAL MANUFACTURER/SUP-
PLIER. AVOID CONTACTING ELECTRICALLY HOT METER
POSTS AND CIRCUIT BOARD COMPONENTS WHILE MAKING
METER ADJUSTMENTS.
NOTE: When submitting correspondence always specify model and
serial number of apparatus.

VERY IMPORTANT SAFETY PRECAUTIONS
This page provides very important safety information related to safety in installation, operation, and
maintenance of this equipment.
WARNING
TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR EQUIPMENT DAMAGE, OBSERVE THE FOLLOWING:
THIS EQUIPMENT SHOULD BE INSTALLED, OPERATED AND SERVICED ONLY BY TRAINED, QUALIFIED PER-
SONNEL WHO ARE THOROUGHLY FAMILIAR WITH THEENTIRE CONTENTS OF THIS INSTRUCTION MANUAL.
WHEN HAZARDOUS CHEMICALS ARE BEING PUMPED, AND/OR ELEVATED PRESSURE/TEMPERATURES
ARE ENCOUNTERED, RIGID PIPE IS RECOMMENDED. WHEN WORKING WITH RIGID PIPING COMPONENTS,
LATERAL AND TORSIONAL FORCES IN THE METERING PUMP SUCTION AND DISCHARGE FITTINGS MUST
BE AVOIDED. THESE FORCES CAN LEAD TO COMPONENT FAILURE, WHICH COULD RELEASE HAZARDOUS
CHEMICALS THAT COULD PRESENT A PERSONAL HAZARD AS WELL AS AN ENVIRONMENTAL HAZARD.
IN RARE CASES, THESE FORCES CANNOT BE ELIMINATED THROUGH THE APPLICATION OF PROPER
PIPING PRACTICES AND/OR PIPING SUPPORT SYSTEMS. IN THESE CASES WPS SHOULD BE CONSULTED
TO AID IN THE SELECTION OF AN APPROPRIATE FLEXIBLE CONNECTOR.
DUE TO THE SINUSOIDAL FLUID DELIVERY CHARACTERISTICS OF A RECIPROCATING METERING PUMP,
ADDITIONAL PRESSURE IS CREATED IN THE SUCTION AND DISCHARGE LINE TO OVERCOME THE INERTIA
OF THE FLUID AT REST IN THE LINES. INERTIAL PRESSURE ENCOUNTERED IN THE LINES IS A FUNCTION OF
SEVERAL FACTORS (LINE SIZE AND LENGTH, VISCOSITY OF THE FLUID, STROKING SPEED, FLUID DELIVERY
RATE, ETC.). THE SUCTION AND DISCHARGE LINES MUST BE SIZED TO THE PRESSURE SURGES DEVELOPED
IN THE LINES. INERTIAL PRESSURE SURGE CAN CREATE STRESSES IN THE PIPING THAT COULD LEAD TO
COMPONENT FAILURE. IF THE PULSING EFFECTS OF THIS PHENOMENON CANNOT BE CONTROLLED BY
PROPER LINE SIZING, THEN ENGINEERING CONTROLS SUCH AS VENTED RISERS, PULSATION
DAMPENERS, OR HEADBOXES CAN BE EMPLOYED TO MINIMIZE THE STRESSES PRODUCED IN THE
PIPING SYSTEM CAUSED BY THE PRESSURE SURGES. IT IS IMPORTANT TO NOTE THAT THESE ENGINEERING
CONTROLSREQUIRE PERIODIC MAINTENANCE. ADDITIONALLY, THE OPERATORS ANDSERVICE PERSONNEL
OF THIS EQUIPMENT MUST HAVE A WORKING UNDERSTANDING OF THE ENGINEERED CONTROL DEVICES
FUNCTION, AND THE CONSEQUENCES OF MISAPPLICATION AND/OR INADEQUATE MAINTENANCE.
IT IS THE RESPONSIBILITY OF THE OWNER TO ENSURE THAT THE INSTALLATION, OPERATION, AND
MAINTENANCE OF THIS EQUIPMENT AND ITS ASSOCIATED COMPONENTS ARE IN COMPLIANCE WITH
ALL FEDERAL, STATE, AND LOCAL REGULATIONS.
AVOID CONTACTING ELECTRICALLY HOT METER POSTS AND CIRCUIT BOARD COMPONENTS WHILE MAK-
ING METER ADJUSTMENTS.
WHEN DEALING WITH HAZARDOUS MATERIALS, IT IS THE RESPONSIBILITY OF THE EQUIPMENT USER
TO OBTAIN AND FOLLOW ALL SAFETY PRECAUTIONS RECOMMENDED BY THE HAZARDOUS MATERIAL
MANUFACTURER/SUPPLIER.

SP-1

ENCORE® 700 METERING PUMP
VERY IMPORTANT SAFETY PRECAUTIONS (CONT'D)
CONSULT YOUR REPRESENTATIVE IF THE PUMP IS TO BE USED UNDER CONDITIONS OTHER THAN
ORIGINALLY SPECIFIED AND IF THERE IS ANY QUESTION REGARDING THE SIZE OF
THE DISCHARGE
LINE.
USE RIGID PIPE WHEN HAZARDOUS CHEMICALS ARE PUMPED AND/OR ELEVATED PRESSURE/TEMPERA-
TURES ARE ENCOUNTERED.
USE EXTREME CARE TO AVOID CONTACT WITH THE MATERIAL AND POSSIBLE SEVERE PERSONAL INJURY.
CONSULT YOUR CHEMICAL SUPPLIER FOR INSTRUCTIONS IN THE PREPARATION OF SOLUTIONS AND THE
HANDLING OF CHEMICALS. OBSERVE ALL RECOMMENDED SAFETY PRECAUTIONS.
DO NOT SPILL SOLUTION. IF ANY SOLUTION IS SPILLED, DILUTE OR WASH AWAY WITH WATER IMMEDI-
ATELY OR FOLLOW SUPPLIER'S INSTRUCTIONS FOR HAZARDOUS MATERIALS.
AVOID BEING SPRAYED WITH LIQUID UNDER PRESSURE. PRIOR TO DISASSEMBLY OF PIPE CONNECTIONS
REFER TO SERVICE SECTION FOR DETAILED INSTRUCTIONS ON RELIEVING PRESSURE AND DRAINING.
ALLOW SYSTEM TO DRAIN FULLY BEFORE ATTEMPTING TO DISASSEMBLE PIPING AND REMOVING VALVES
AND/OR HEAD.
SINCE THE STORAGE AND HANDLING OF SODIUM CHLORITE PRESENTS VERY SPECIFIC HAZARDS, THE
USER MUST SEEK THE ADVICE OF THE SODIUM CHLORITE SUPPLIER WITH REFERENCE TO STORAGE FA-
CILITIES, HANDLING PRECAUTIONS AND HEALTH HAZARDS.
SODIUM CHLORITE, WHEN FINELY DIVIDED IN THE PRESENCE OF ORGANIC COMPOUNDS, IS A POSSIBLE
FIRE HAZARD. FOR THIS REASON, EXTREME CARE MUST BE EXERCISED TO PREVENT SOLUTIONS FROM
DRYING OUT IN THE THREADED PORTIONS OF THE PUMP BODY AND RELATED PARTS. OBSERVE CARE-
FULLY THE MANUFACTURER/SUPPLIER'S RECOMMENDED SAFETY PROCEDURES AND THE HANDLING
AND STORAGE PROCEDURES IN THIS MANUAL.
WHEN SERVICING HEADS AND/OR VALVES, FOLLOW PROCEDURES IN THE SERVICE SECTION FOR
DISASSEMBLY.
USE EXTREME CARE TO AVOID CONTACT BECAUSE LIQUID IS PRESENT BETWEEN DISCHARGE DRAIN
VALVE AND UNION ELBOW. FLUSH SPILLED LIQUID IMMEDIATELY.
USE EXTREME CARE TO AVOID CONTACT WITH THE MATERIAL AND POSSIBLE SEVERE PERSONAL INJURY.
WHEN USING HAZARDOUS MATERIAL, OBSERVE ALL SAFETY PRECAUTIONS RECOMMENDED BY THE
HAZARDOUS MATERIAL MANUFACTURER/SUPPLIER. USE APPROPRIATE PROTECTIVE CLOTHING AND EYE
PROTECTION WHEN HANDLING HAZARDOUS MATERIAL.
USE EXTREME CARE TO AVOID CONTACT WITH LIQUID PRESENT IN HEAD. ALLOW SUCTION VALVE TO
FALL INTO SUITABLE CONTAINER AND CATCH LIQUID.
TURN POWER OFF BEFORE SERVICING.
