Valmet Oyj has launched its new Pulp Filtrate Extractor, designed to provide pulp makers with increased precision in pH measurement. The company states that the new extractor offers high availability and accurate process temperature and measurement conditions, ensuring the accuracy of pH and residual chemical measurements.
The Pulp Filtrate Extractor is presented as an upgrade from previous Valmet models, including the Valmet Piston and Valmet Screen Extractor. It is intended to enable pulp producers to achieve precise measurements in pulp filtrate by enhancing measurement conditions and increasing system uptime. Valmet reports that the new extractor delivers up to 70 percent greater flow compared to competing solutions, which contributes to higher filtrate temperatures and better conditions for exact pH measurements.
The design also focuses on reducing maintenance requirements through self-cleaning capabilities. Additionally, wearing parts are engineered for easy replacement without the need for specialized tools.
Matti Selkälä, Business Manager, Pulp and Energy Analyzers, Automation Solutions, Valmet, commented, “Our long experience with pulp filtrate sampling has led to a breakthrough in sampling technology. Valmet Pulp Filtrate Extractor provides a solid basis for advanced process controls in the fiberline.”
Technically, the Valmet Pulp Filtrate Extractor provides a continuous fiber-free filtrate sample suitable for various measurements, including pH, residual chemicals, and conductivity. It is designed to integrate seamlessly into existing locations. The new extractor weighs 30 to 50 percent less than competing solutions, aiming for safer installation and maintenance. Its self-cleaning function utilizes the existing process filtrate, eliminating the need for external compressed air or water.
