Flow rate up to 2000 l/h & pressure up to 225 kg/cm²g - Engineered for demanding dosing applications, delivering high flow capacity and exceptional pressure handling while complying with API 675 standards.
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.
0–100% flow adjustment during operation or shutdown - 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 for extended service life.
