1.1 Introduction
Congratulations on purchasing the Flowrox variable speed Peristaltic Metering Pump.
Your Flowrox pump is pre-congured for the tubing that shipped with your metering pump.
Your new pump has been pressure tested at the factory with clean water before shipping. You may notice trace amounts of clean water in the
pre-installed tube assembly. This is part of our stringent quality assurance program.
Flowrox FXM pumps are for industrial and laboratory applications. Only qualified personnel is allowed to install and operate the pump.

• The Flowrox Peristaltic Pump’s motor speed is linear over
the entire 0.02% to 100% adjustment range.
• Output versus pressure is nearly linear in all models.
Larger tubes exhibit greater losses.
• The pressure, temperature, operational speed, application
media and viscosity will affect hose lifetime.
• For optimum tube life, specify the pump so that it operates
at the lowest possible RPM and pressure.
* Inlet/outlet connection type:
blank = 3/8” OD x 1/4” ID tubing compressions type
connections (available on FXM2 only)
P = 1/2” MPT
B = 1/2” ID hose barb type connections (available on FXM3

1.5 Features
• Peristaltic pump design does not have valves that can
clog requiring maintenance.
• Self priming even against maximum line pressure.
By-pass valves are not required. Cannot vapor lock or
lose prime. Siphoning cannot occur.
• Output rates to: 840 liter/h and pressures up to 8.6 bars.
• No maintenance brushless variable speed motor.
• Specially engineered tubing for long life at high
pressures.
• Non-contact capacitive Tube Leak Detection (TLD)
system. Senses tube failure by detecting chemical in the
pump head. No false triggering.
• 5000:1 turndown ratio.
• SCADA Inputs include: 4-20mA, 0-10VDC, and Pulse
inputs for remote external speed control and 0-30 VDC /
contact closure remote start/stop.
• Operator friendly digital touch pad with menu driven
software.
• Multi-color backlit LCD displays remote/local control
status, motor speed, output rate, input signal values,
service and alarm status.
• Outputs include: Scalable 4-20mA or pulse, one
250V/6A relay and four 125VAC 0.5Amp / 30VDC
2Amp contact closures assignable to monitor up to 17
different pump functions including TLD, FVS, remote/
local control setting, motor on, fault, current operating
mode, and others.
• Two CNC precision machined squeeze rollers and two
alignment rollers for optimum squeeze, unparalleled
accuracy, and tube life.
• Heavy duty rotor - plastic rotor means no flexing and
increased accuracy (no metal springs or hinges to
corrode).
• Inject at maximum pressure in either direction
(clockwise and counter clockwise).
• Compatible with output Flow Verification Sensor (FVS)
system.
• Auto-restart feature which will restore pump to operating
state it was in when power was lost.

2 Installation
Risk of chemical overdose. Make sure pump does not
overdose chemical during backwash and periods of no
flow in circulation system.
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.
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.
2.1 Mounting Location
Choose an area located near chemical supply tank, chemical
injection point, and electrical supply. Install pump where
it can be easily serviced. Note, Pump is not certied for
classied EX/ATEX areas
• Mount pump to a secure surface using fixing plate.
• 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.
• A backflow prevention check valve is recommended at
the discharge of the pump to prevent system fluid from
flowing back through the pump during tube replacement
or if the tube should rupture.
• A pressure relief valve is recommended at the discharge
of the pump to prevent premature wear and damage to
the pump tube in the event the discharge line becomes
blocked.
• The FXM does not require back pressure. Pressure
regulator valves are not required. Keep the discharge
pressure as low as possible to maximize tube life.
• An anti-siphon valve is not required, siphoning cannot
occur.
