4.1
Mounting Location
Choose an area located near chemical supply tank, chemical injection point, and electrical supply. Install pump
where it can be easily serviced.
316SS Mounting brackets are included. Mount pump to a secure surface using enclosed mounting hardware.
Mount pump close to injection point. Keep inlet (suction) and outlet (discharge) tubing as short as possible.
Longer discharge tubing increases back pressure at pump head.
Important!
Install a back flow prevention check valve at discharge side of pump to prevent system fluid from
flowing back through pump during tube replacement or if tube should rupture.
Important!
A pressure relief valve is recommended at discharge of pump to prevent premature wear and damage to pump
tube in event discharge line becomes blocked.
Flex-Pro does not require back pressure. Keep discharge pressure as low as possible to maximize tube life.
4.2
Dimensions
All diagrams are strictly for guideline purposes only. Always consult an expert before
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.
