Blue-White FLEXFLO® A2 Peristaltic Metering Pump
Precision Chemical Dosing • Low Maintenance • Industrial-Grade Reliability
The Blue-White FLEXFLO® A2 Peristaltic Metering Pump is engineered to simplify chemical feed systems while delivering highly accurate, smooth, and consistent dosing. Designed with a gentle, low-shear pumping action, the A2 is ideal for shear-sensitive, viscous, off-gassing, or gaseous chemicals that can challenge traditional metering pumps.
Unlike diaphragm or solenoid pumps, the FLEXFLO® A2 eliminates check valves, seals, and complex wetted components, dramatically reducing maintenance, downtime, and replacement part costs. Its rugged construction and NEMA 4X / IP66 enclosure make it a dependable solution for harsh industrial, municipal, and commercial environments.

✅ How Peristaltic Pumping Works
The FLEXFLO® A2 is a positive displacement peristaltic pump, meaning fluid only contacts the chemically resistant pump tube, not internal components. This design enhances chemical compatibility and simplifies maintenance — just replace the tube when worn.
Each pump is pre-configured with the proper tubing assembly. Tubes are labeled with identification codes (such as ND, NEE, etc.) for quick and accurate reordering.
✅ Quality Assurance You Can Trust
Every Blue-White FLEXFLO® A2 pump is factory pressure-tested with clean water before shipment. You may notice small traces of water in the tubing upon arrival — this is normal and part of Blue-White Industries’ strict quality control process.
✅ Ideal Applications
-
Water & Wastewater Treatment
-
Commercial Pools & Aquatics
-
Industrial Chemical Injection
-
Agriculture & Fertigation
-
Car Wash & Process Systems
-
Cooling Towers & Boilers
The Blue-White FLEXFLO® A2 Peristaltic Metering Pump delivers precision chemical dosing, reduced maintenance, and reliable long-term performance — making it a top choice for professionals who demand accuracy and durability in demanding environments.
