Chemicals used may be dangerous and should be used carefully and according
to warnings on the label. Follow the directions given with each type of chemical.
Do not assume chemicals are the same because they look alike. Always store
chemicals in a safe location away from children and others. We cannot be
responsible for the misuse of chemicals being fed by the pump. Always have the
material safety data sheet (MSDS) available for any fluid being pumped.
•
All pumps are pretested with water before shipment. Remove head and dry
thoroughly if you are pumping a material that will react with water, (i.e. sulfuric
acid, polymers). Valve seats, ball checks, gaskets, and diaphragm should also be
dried. Before placing pump into service, extreme care should be taken to follow
this procedure.
•
Valve cartridges are stamped to indicate fluid flow direction. Always install so
that markings read from top to bottom, with the arrow pointing in the direction of
flow.
•
When metering hazardous material DO NOT use plastic tubing, strictly use proper
rigid pipe. Consult supplier for special adapters or valve assemblies.
• Pump is NOT to be used to handle or meter flammable liquids or materials.
•
Standard white discharge tubing is not recommended for installations exposed
to direct sunlight. Consult supplier for special black tubing.
•
Factory will not be held responsible for improper installation of pump, or
plumbing. All cautions are to be read thoroughly prior to hookup and plumbing.
For all installations a professional plumber should be consulted. Always adhere
to local plumbing codes and requirements.
•
When using pump with pressurized systems, make sure the pressure of the system
does not exceed the maximum pressure rating on the pump data label. Be sure to
depressurize system prior to hook up or disconnecting a metering pump.

devices and may reset unexpectedly.
