Flow rate up to 2000 l/h & pressure up to 225 kg/cm²g - Engineered for demanding dosing applications, delivering high flow capacity.
Provides ±1% accuracy from 10% to 100% stroke, with ±3% repeatability and ±3% linearity for dependable process performance.
Minimizes pulsation and shock while enabling fine stroke adjustments that can be securely locked to maintain settings.
Allows capacity changes while the pump is running or stopped and offers a 10:1 turn-down ratio for enhanced operating flexibility.
Features corrosion-resistant SS316 wetted parts, threaded end connections, and a 34 mm stroke length for reliable long-term operation.
Suitable for liquid temperatures up to 120°C, ambient temperatures up to 50°C, viscosities up to 1800 cps, and includes oil-bath lubrication.
