3Installation, Operations & Maintenance Manual
PRECAUTIONS
The following precautions should be taken when working with metering pumps.
Please read this section carefully prior to installation.
Protective Clothing
ALWAYS wear OSHA approved protective clothing, face shield, safety glasses and gloves
when working on or near your metering pump. Additional precautions should be taken
depending on the solution being pumped. Refer to Safety Data Sheets (SDS) for the solution
being pumped.
Hearing Protection
It is recommended that hearing protection be used if the pump is in an environment where the
time weighted average sound level (TWA) of 85 dbA is exceeded.
Electrical Safety (Lock-out / Tag-out)
• Remove power and ensure that it remains off while maintaining pump.
• DO NOT FORGET TO CONNECT THE PUMP TO EARTH
• Electric protection of the motor (Thermal protection or by means of fuses) is to correspond
to the rated current indicated on the motor data plate.
Liquid Compatibility
Verify if the materials of construction of the wetted components of your pump are
recommended for the solution (chemical) to be pumped.
Pumps Water “Primed”
All pumps are tested with water at the factory. If your process solution is not approved with
water, ush the Pump Head Assembly with an appropriate solution before introducing the
process solution.
Plumbing and Electrical Connections
Always adhere to your local plumbing and electrical codes.
Line Depressurization
To reduce the risk of chemical contact during disassembly or maintenance, the suction and
discharge lines should be depressurized before servicing.
Over Pressure Protection
To ensure safe operation of the system it is recommended that some type of safety/pressure
relief valve be installed to protect the piping and other system components from damage due
to over-pressure.
