The chemical feed pumps a municipality uses to treat its potable water need to not only be accurate and durable, they also are often required to handle high volumes. The FLEXFLO M5 Peristaltic Metering Pump from Blue-White Industries hits the mark, as it’s capable of delivering outputs up to 9 gpm at only a 75 RPM motor speed, maximizing tube life and reducing overall maintenance. The higher output answers a huge industry need in the municipal market, according to Patrick Murphy, director of engineering with Blue-White Industries.

“Pumps this size in the industry typically need an external controller to control the motor,” says Murphy. “Instead, ours has all the controls built into the pump.”

The all-inclusive M5 includes a roller assembly that reduces pulsations by 80%, and the pump tube assemblies along with dual channel tubing deliver excellent tube life. Casters placed on the back of the pump, as well as handles situated on the pump head cover assist in moving the large pump and help with making the installation process easy. A chemical-resistant enclosure houses an energy-efficient BLDC motor, premium control boards and all connections. It features a large 5-inch display for easy viewing with simple and intuitive touchscreen controls and icon-driven menu navigation. Remote control signal options include Pulse, 4-20mA, Modbus TCP, EtherNet/IP, and PROFIBUS for enhanced supervision and automation for critical metering and transfer applications. “The energy-efficient BLDC motor is an improvement over AC motors that lose most of their efficiency through heat,” says Murphy.

For applications where chemical demand is high, such as some municipal water treatment applications, the FLEXFLO M5 is the answer, according to Murphy.

“We would always hear from customers that wanted to use our products but couldn’t because we couldn’t get to the flow rate required for their application,” he says. “That is what led to the initial development of the pump. It’s a good fit to the industry because it meets a higher chemical feed application while also being feature rich in controls.”

Accordingly, the increase in capacity has got the industry talking. “We haven’t started beta testing, but people at tradeshows didn’t think it was real at first,” says Murphy. “They were taken aback at its size and features. We have had customers already put in reservations in excitement from just seeing the product.”
