Flow rate up to 192 l/h & pressure up to 90 kg/cm²g - Designed for demanding metering applications, delivering reliable performance at high pressures while conforming to API 675 standards.
Provides ±1% accuracy from 10% to 100% stroke, with ±3% repeatability and ±3% linearity for consistent dosing results.
Variable eccentric drive with lockable micrometer setting - Minimizes pulsation and shock while enabling precise stroke adjustment and secure locking for stable operation.
Flow adjustment from 0–100% while running or stopped - Allows operators to change the dosing rate without interrupting the process and offers a 10:1 turn-down ratio for greater flexibility.
SS316 liquid end with threaded connections - Features corrosion-resistant SS316 wetted parts as standard, alternative material options on request, and a 15 mm stroke length for dependable performance.
Suitable for liquid temperatures up to 120°C, ambient temperatures up to 50°C, viscosities up to 2450 cps, and incorporates oil-bath lubrication for long service life.
