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 THE ENTIRE 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 A
NDSERVICE 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.
