Mounting Location
1. Choose an area located near the chemical supply tank, chemical injection point, and electrical supply. Also,
choose an area where the pump can be easily serviced.
2. Finding a secure surface and using the provided 316SS mounting bracket, mount the pump close to the
injection point. Keep the inlet (suction) and outlet (discharge) tubing as short as possible.
NOTE
: Mounting the pump lower than the chemical container will gravity-feed chemical into it. This “flooded
suction” installation will reduce output error due to increased suction lift. A shut-off valve, pinch-clamp, or
other means to halt gravity-feed to the pump must be installed during servicing.
NOTE
: Install a back flow prevention check valve at the discharge side of the pump to prevent the system fluid
from flowing back through pump during tube replacement or during tube rupture.
NOTE
: It is recommended to have a pressure relief valve at the discharge side of the of pump to prevent
premature wear and damage to the pump tube, in the event that the discharge line becomes blocked.
NOTE
: The
does not require back pressure. Keep the discharge pressure as

low as possible to maximize the tube life.

installing metering pump on specialized systems. Metering pump should be serviced by
qualified persons only.
!
Always wear protective clothing, face shield, safety glasses and gloves when working on or
near your metering pump. Additional precautions should be taken depending on solution
being pumped. Refer to MSDS precautions from your solution supplier.
Risk of chemical overdose. Be certain pump does not overdose chemical during backwash
and periods of no flow in circulation system.
