Electronic Diaphragm Chemical Dosing Metering Pump

About this part

Microprocessor-controlled electronic diaphragm chemical dosing metering pump designed for accurate injection of water conditioning chemicals directly into boiler feed lines and hotwells. Delivers precision dosing of oxygen scavengers (sodium sulfite/hydrazine), phosphate scale inhibitors, pH neutralizing amines, and biocides to prevent boiler tube scaling, pitting, and caustic embrittlement.

Key features

• Heavy-duty solid PTFE (Teflon) machined diaphragm for unmatched chemical corrosion resistance
• PVDF / PP liquid head with double-ball check valves for leak-tight precision metering
• Dual stroke length and electronic pulse frequency controls for accurate micro-dosing
• IP65 acid-resistant fiberglass-reinforced thermoplastic housing
• Manual and automated 4-20mA / pulse input flow proportional pacing

Typical applications and wear

Boiler water oxygen scavenging, cooling tower water treatment, RO antiscalant injection, and effluent pH control. Wear involves diaphragm mechanical fatigue and check ball seat fouling.

Compliance

Essential for maintaining boiler water chemistry within ASME/ABMA standards to prevent boiler tube overheating and scaling.
