INTRODUCTION
This manual provides installation, operating, and maintenance instructions for
the UGSI Chemical Feed, Inc. 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 confi gurations, and a
single or double simplex confi guration. 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 Rectifi er (SCR) controls drive motor speed varia-
tions 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
INJURY OR DAMAGE TO THE EQUIPMENT, THIS EQUIPMENT
SHOULD BE INSTALLED, OPERATED AND SERVICED ONLY
BY TRAINED, QUALIFIED PERSONNEL WHO ARE
THOROUGHLY 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/SUPPLIER. 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
PERSONNEL WHO ARE THOROUGHLY FAMILIAR WITH THE ENTIRE CONTENTS OF THIS INSTRUC-
TION MANUAL.
WHEN HAZARDOUS CHEMICALS ARE BEING PUMPED, AND/OR ELEVATED PRESSURE/TEMPERATURES
ARE ENCOUNTERED, RIGID PIPE IS RECOMMENDED. WHEN WORKING WITH RIGID PIPING COMPO-
NENTS, 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 UGSI CHEMICAL FEED, INC. SHOULD BE CONSULTED TO AID IN THE SELECTION OF AN AP-
PROPRIATE 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, STROK-
ING 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 CONTROLS REQUIRE PERIODIC MAINTE-
NANCE. ADDITIONALLY, THE OPERATORS AND SERVICE 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
MAKING 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

CF.440.400.001.IM.0417
ENCORE® 700 METERING PUMP
VERY IMPORTANT SAFETY PRECAUTIONS (CONT’D)
CONSULT YOUR UGSI CHEMICAL FEED, INC. 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/
TEMPERATURES 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
IMMEDIATELY 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
FACILITIES, 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
CAREFULLY 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.
