Flex-Pro® M-4

• 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.
• Gentle and efficient pumping action
• Quiet and smooth chemical feed
• Tube failure detection (TFD) system, Patented
• Flow Verification Sensor (FVS) ready
• Multiple signal inputs and outputs (4-20mA, etc.)
• Simple to configure

• Feed Rates up to 158.5 GPH / 600 LPH
• Pressures up to 125 PSI / 8.6 Bar
• 10,000:1 Turndown Ratio
• Brushless DC motor, zero maintenance
• Inputs include: Scalable 4-20mA, 0-10Vdc, pulse inputs, Remote Start / Stop
• Outputs: Scalable 4-20mA, pulse, six amp relay and three assignable contact closures (one 250V/6A relay and three 115V/1A contact closures assignable to monitor various pump functions including TFD, FVS, revolution counter, remote/local, forward/reverse, input signals, output signals, motor on, motor fault, operating mode setting, and others)
• Rotor revolution counter, totalizes rotor revolutions with user programmable alarm set-point for tube maintenance.
• Tube timer, totalizes hours of run time on installed tubing.
• VGA Graphic multi-color backlit LCD displays remote/local control status, motor speed, output rate, input signal values, service and alarm status in three easy to see colors.
• Two CNC precision machined squeeze rollers and two alignment rollers provide factory calibrated optimum squeeze for unparalleled accuracy and extra long tube life.
• Heavy duty rotor – single piece plastic rotor means no flexing and increased accuracy with no metal springs or hinges to corrode.
• Inject at maximum pressure in either direction (clockwise or counter clockwise).
• Specially engineered tubing for long life at high pressures.
• Tube Failure Detection (TFD) system, patented. Senses tube failure by detecting chemical in the pump head. No false triggering.
• Compatible with Blue-White’s output Flow Verification Sensor (FVS) system
