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 pump 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.

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 pump 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.

pressed and released.
Flex-Pro pump is equipped with a Tube Failure Detection (TFD) system which is designed to stop pump in event
pump tube should rupture and chemical enters pump head. This patented system is capable of detection pres-
ence of a large number of chemicals including Sodium Hypochlorite (chlorine), Hydrochloric (muriatic) Acid,
Sodium Hydroxide, and many others.
Minimum and Maximum setting = 75 % to 100%
Default Setting = 75% (75% is recommended; triggers with most water treatment chemicals without false alarms)
Important: 100% sensitivity setting may trigger false alarm by washdown or rain. 100% setting is only recommended
when absolutely necessary.
Confirm chemical detection - To determine if your chemical will be detected by system, remove pump tube and rotor. Place a small
amount of chemical in bottom of pump head - just enough to cover sensors. Turn on pump. If TFD system detects chemical, pump will
stop after two seconds and TFD alarm screen will display. Press STOP button to clear alarm.

Flow Verification Sensor is designed to give you two installation options.
Sensor can be installed:

!Anywhere on suction side of M2 pump.
Wiring for sensor can be connected directly to an M2 pump. Pump will stop pumping if sensor detects no flow. A
relay will then close allowing for remote alarm indication or initiation of a back-up injector pump. Install FVS Flow
Sensor - Flow Verification Sensor should be installed on inlet (suction) side of pump tube. Sensor includes a PVC
tubing insert, located inside sensors female thread connection, that is designed to seal sensor onto pump tube
inlet adapter. Thread sensor onto pump tube until tubing insert is snug against pump tube inlet fitting - do not
over-tighten.
7.2 Mode 0 - Set FVS (flow verification system) - Continued
Confirm FVS flow range - Flow Verification Sensor (FVS) will only function
within its operating range. See chart for available ranges.
Example: Sensor model FV-100 has an operation range of 30-300 ml/min
when used as a flowmeter. However, due to pressure drop across sensor,
pump’s suction capability is limited to 14.7 psi. When used as a Flow
Verification Sensor with a peristaltic pump, effective operating range is
reduced to 30-200 ml/min.
NOTE: If pump output is less than 30 ml/min, sensor will not detect chemical
and a signal will not be sent to pump, resulting in an alarm condition.
NOTE: For low viscosity (water-like) fluids only. Consult factory if attempting
to use with viscous fluids.
