Blue-White FLEXFLO M3 Peristaltic Metering Pump Overview

The FLEXFLO M3 combines the simplicity of peristaltic pumping with sophisticated process controls to provide highly accurate chemical dosing across an exceptionally wide operating range. Unlike diaphragm metering pumps, the M3 contains no check valves that can clog, stick, or vapor lock, making it particularly well suited for sodium hypochlorite, hydrogen peroxide, polymers, ferric chloride, sulfuric acid, and other difficult-to-feed chemicals. Only the pump tube contacts the process fluid, allowing rapid maintenance while minimizing chemical compatibility concerns. The intuitive touchscreen interface provides access to operating parameters, maintenance reminders, alarm history, diagnostics, and communication settings for integration into modern SCADA and process automation systems.

Common Applications for the Blue-White FLEXFLO M3 Peristaltic Metering Pump

The FLEXFLO M3 is commonly used for sodium hypochlorite dosing, pH adjustment, sulfuric acid feed, ferric chloride injection, polymer dosing, nutrient delivery, chemical transfer, industrial process control, pharmaceutical manufacturing, laboratory process development, municipal water treatment, wastewater treatment, and pilot plant applications. The self-priming peristaltic design is especially beneficial when pumping chemicals that tend to off-gas or crystallize, where conventional diaphragm pumps often require additional maintenance.

Ideal Lab Types for the Blue-White FLEXFLO M3 Peristaltic Metering Pump

This metering pump is well suited for municipal water treatment facilities, biotechnology companies, pharmaceutical manufacturers, chemical processing plants, environmental laboratories, university research facilities, pilot plants, food and beverage manufacturers, and industrial quality control laboratories. Facilities utilizing laboratory reactors, pH controllers, water purification systems, chemical storage tanks, and process automation equipment frequently incorporate peristaltic metering pumps into automated dosing systems.

Refurbishment and Testing Process

At American Instrument Exchange, each refurbished FLEXFLO metering pump is inspected and evaluated by our technicians prior to shipment. Testing procedures may include verification of motor operation, touchscreen functionality, pump head performance, speed control, Tube Failure Detection operation, communication interfaces, electrical safety testing, and general operational evaluation. The pump head, rollers, tubing, and drive components are inspected for wear, and serviceable components are replaced as needed to help ensure dependable performance. Final cleaning and inspection are completed before packaging and shipment.

Shipping and Installation Considerations

The Blue-White FLEXFLO M3 should be installed on a secure mounting surface with adequate clearance for tubing replacement and routine maintenance. Buyers should verify electrical compatibility and select tubing appropriate for the intended chemical application. Because only the pump tube contacts the process fluid, routine tube replacement is quick and straightforward, minimizing downtime and maintenance costs. The unit is carefully packaged to protect the touchscreen, pump head, electronics, and motor during shipment.

Related Laboratory Equipment

Laboratories and industrial facilities purchasing chemical metering pumps often also require laboratory mixers, magnetic stirrers, pH meters, water baths, peristaltic pumps, laboratory reactors, and water purification equipment. American Instrument Exchange offers a wide selection of refurbished laboratory and process equipment to support biotechnology, pharmaceutical manufacturing, analytical chemistry, water treatment, and industrial processing applications.

Blue-White FLEXFLO M3 Peristaltic Metering Pump Frequently Asked Questions

What advantages does the FLEXFLO M3 offer over diaphragm metering pumps?

Because the FLEXFLO M3 uses peristaltic pumping technology, it requires no check valves, is self-priming, resists vapor lock, and only exposes the pump tube to the chemical being pumped. This simplifies maintenance and improves reliability with difficult chemicals.

What is Tube Failure Detection (TFD)?

Blue-White's patented Tube Failure Detection system continuously monitors the pump head for leaks and immediately alerts operators if the pump tube ruptures, helping prevent chemical spills and equipment damage.

Can the FLEXFLO M3 be integrated into automated control systems?

Yes. The M3 supports Ethernet/IP, Modbus TCP, PROFIBUS, 4-20 mA, pulse input, and other communication protocols for seamless integration with SCADA and process automation systems.

What chemicals can the FLEXFLO M3 handle?

The FLEXFLO M3 is commonly used for sodium hypochlorite, sulfuric acid, polymers, ferric chloride, hydrogen peroxide, alum, caustic solutions, and many other chemicals. Appropriate tubing should always be selected based on chemical compatibility.

What warranty is included?

This refurbished Blue-White FLEXFLO M3 Peristaltic Metering Pump includes a 90-day warranty from American Instrument Exchange.
