F-300

CHEM-FEED® Multi-Diaphragm Metering Pump

An aquatics industry standard for over six decades, Blue-White’s F-300 Flow Meter is accurate and has reduced space requirements for installation. The aerodynamic pitot tube is designed for smooth fluid flow through the meter. There are four capture points resulting in no float bounce.

New features include:

  • PVDF cap that won’t fade or crack
  • PVDF float that won’t stick, is chemical resistant, and easy-to read-color
  • Improved accuracy

Recommended Accessories:
F-300S, F-300SL Flow Switch and Sensor
