OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING
Be sure hoses and other components can
withstand fluid pressures developed by this pump.
Check any hoses for damage or wear. Be certain dis-
pensing device is clean and in proper working condi-
tion.
WARNING
IMPROPER GROUNDING. Can increase
spark and electrical shock risk, resulting in severe in-
jury or death. Ground pump and pumping system.
y
The pumping system must be grounded when it is
pumping, flushing, recirculating, or spraying flamma-
ble materials such as paints, solvents, lacquers, etc.
or used in a location where surrounding atmosphere
is conducive to spontaneous combustion. Ground the
dispensing valve or device, containers, hoses, and any
object to which material is being pumped.
y
Secure pump, connections, and all contact points to
avoid vibration and generation of contact or static
spark. Consult local building codes and electrical
codes for specific grounding requirements. After
grounding, periodically verify continuity of electrical
path to ground. Test with an ohmmeter from each
component (e.g., hoses, piping, pump, clamps, motor,
base plate, etc..) to ground to ensure continuity. Ohm-
meter should show 0.1 ohms or less.
WARNING
HAZARDOUS PRESSURE. Can result in
serious injury or property damage. Do not service or
clean pump while the system is pressurized.
WARNING
HAZARDOUS MATERIALS. Can cause
serious injury or property damage. Do not attempt
to return a pump to the factory or service center that
contains hazardous material. Safe handling practices
must comply with local and national laws and safe-
ty code requirements. Obtain Material Safety Data
Sheets on all materials from the supplier for proper
handling instructions.
CAUTION
Check pump seals, elastomers, and all
wetted parts to assure compatibility before using
commission of the product.
y
Verify the chemical compatibility of the pump wetted
parts and the substance being pumped, flushed or
recirculated. Chemical compatibility may change with
temperature and concentration of the chemical(s)
within the substances being pumped, flushed or cir-
culated. For specific fluid compatibility, consult the
chemical manufacturer.
CAUTION
Maximum temperatures are based on
mechanical stress of seals and elastomers only. Cer-
tain chemicals will significantly reduce maximum safe
operating temperature. Consult the chemical manu-
facturer for chemical compatibility and temperature
limits.
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices, under-
stand it’s limitations, and wear safety goggles / equip-
ment when required.
CAUTION
Do not use the pump for the structural
support of the piping system. Be certain the system
components are properly supported to prevent stress
on the pump parts.
CAUTION
Prevent unnecessary damage to the
pump. Do not allow pump to operate in a dry run
condition or under cavitating conditions for extended
periods.
CAUTION
Use only genuine MP Pumps
®
replace-
ment parts to assure compatible pressure rating and
longest service life.
CAUTION
The mechanical seal in the pump must
not be operated dry.
CAUTION
If a pump will be idle in freezing weather
it should be drained or filled with the proper an-
ti-freeze.
NOTICE
Pump should be installed in the position
consistent with the manufactures specifications.
NOTICE
Re-torque all fasteners before operation.
Creep of housing and gasket materials may cause
fasteners to loosen. Re-torque all fasteners to insure
against fluid leakage.
WARNING
= Hazards or unsafe practices which could
result in severe personal injury, death or
substantial property damage.
CAUTION
= Hazards or unsafe practices which could
result in minor personal injury, product
or property damage.
NOTICE
= Important installation, operation or
maintenance information.
