Precision Chemical Dosing & Injection
Controlled Delivery Driven by Analytical Feedback.
Over-dosing wastes expensive chemicals and causes environmental liabilities. Under-dosing causes scaling and corrosion. Walchem electronic metering pumps deliver micro-precision stroke-by-stroke pacing.
How This Technology Works
Microprocessor Solenoid Drive: Generates up to 360 strokes per minute with turndown ratios up to 1800:1 for pinpoint chemical delivery.
Flow-Proportional & 4-20mA Feedback: Adjusts dosing rates dynamically according to flowmeters and online analytical analyzers.
Auto-Degassing & High-Viscosity Liquid Ends: Prevents vapor lock when pumping off-gassing chemistries like sodium hypochlorite.
Integrated Stroke Sensor & Verification: Confirms physical chemical injection and alarms upon line blockage or empty tank.
