• No Valves, No Clogs, No Problems.

    Peristaltic Metering Pumps handle gaseous, viscous and abrasive fluids.

Blue-White Peristaltic Metering Pumps offer exclusive, Patented Technology, keeping both operator and facility safe from harmful chemical spills. This Standard Feature not only shuts off a pump whose tube has ruptured, the system can be set to activate an alarm relay, or communicate with SCADA systems.

Pro-Series® Flex-Pro® Peristaltic Metering Pumps

ProSeries® pumps are engineered rugged, durable and capable of enduring demanding environments. The Flex-Pro® peristaltic metering pump design does not have valves that can clog, and are capable of injecting a wide variety of chemicals both viscous and aggressive, with a smooth, low-velocity action.
Specially engineered tubing for long life and high pressures meets FDA 21 CFR requirements for food contact applications. Exclusive TFD (Tube Failure Detection) system (Patent No. 7,001,153 and 7,284,964) senses tube failure by detecting chemical in the pump head, sending an alarm.

Model A2

The Pro-Series® Flex-Pro® A2 peristaltic metering pump provides solutions for treatment in smaller applications and features Flex-A-Prene® Dual Channel tubing engineered to last 4X longer than conventional tubing design. Intelligent control system permits connection to SCADA or other remote controllers for dosing control. Communications protocols available: Profibus DPV1, Modbus RTU, and more. A2 features a 100:1 turndown ratio.

Models A3 & A4

Model A3 & A4 are designed for high volume metered pumping. The brushless DC Variable Speed motor allows for a smooth and seamless ramp up and down of fluid output. These models are cabable of proportional feed, pulse output and a security lockout on the touchpad. A3 & A4 allow for a 2500:1 turndown ratio.

A-100N & A-1600 Peristaltic Metering Pumps

FLEXFLO® Peristaltic metering pumps are suited for lower feed demand applications. Because there are no valves to clog, FLEXFLO® pumps are suitable for use with gas forming chemicals, such as chlorine.
There are three tube material options which allow for compatibility with a wide range of oil based fluids, acids, and alcohols.

FLEXFLO® Pumps are fitted with the exclusive built-in Tube Failure Detection system, Patent No. 7,001,153 and 7,284,964. If non-compatible chemical is detected in the head, the pump will automatically shut off, and will not restart until the chemical has been removed.
