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.
