Flow up to 457.6 l/h & pressure up to 125 kg/cm²g
Provides accurate metering with ±1% flow accuracy, ±3% repeatability, and ±3% linearity across a 10:1 turn-down ratio.
Variable eccentric drive with lockable micrometer adjustment - Minimizes pulsation and hydraulic shock while enabling precise stroke setting and secure adjustment locking.
0–100% capacity adjustment while running or stopped - Allows smooth, continuous flow control without interrupting operation, ensuring maximum process flexibility.
SS316 liquid end with threaded connections - Features corrosion-resistant SS316 wetted parts as standard, with alternative materials available on request, and a 16 mm stroke length for dependable performance.
Handles pumped liquid temperatures up to 120°C and ambient temperatures up to 50°C, with oil-bath lubrication for long-term durability and reduced maintenance.
