Watson-Marlow brings higher flows to Qdos pump offering

Watson-Marlow Fluid Technology Solutions (WMFTS) has launched the Qdos™ H-FLO chemical metering and dosing pump, designed specifically for higher flow rates up to 600 litres per hour.

Qdos H-FLO delivers the same outstanding accuracy and reliability as other Qdos pumps but for higher flow rates with a variety of pumpheads and a range of different tube material to ensure chemical compatibility with the process fluid, the company claims. It offers flexibility to be scalable with a customer’s process, whether it is in water and wastewater treatment, mining and mineral processing, chemical applications in food and beverage or pulp and paper.

The release of Qdos H-FLO enhances the range of Qdos pumps by offering flow rates up to 600 l/h and pressure capability up to 7 bar (102 psi). The pump also comes with RFID Pumphead detection to ensure confirmation of correct pumphead; a revolution counter for pumphead service maintenance; leak detection and fluid containment to prevent spills and chemical exposure upon pumphead expiry; network integration, control and communication options include EtherNet/IP, PROFINET and PROFIBUS for easy integration with SCADA/PLC; and one common pump drive with several pumphead options for changing process conditions and chemistries.

Like the rest of the Qdos range of peristaltic pumps, Qdos H-FLO cuts costs through higher precision chemical metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing, WMFTS says.

Applications for the pump include flocculants, acids/alkalis and mining reagents.

Adeel Hassan, Product Manager at WMFTS, said: “The high accuracy and repeatability of our pumps helps to achieve cost savings in chemical usage which also assists our customers in their journey towards net-zero targets. While the pump has inherited unique features from the current Qdos range, it also brings several new-to-market features to make chemical dosing simpler, safer and cost-effective.

“Customer feedback has been a fundamental driver in developing Qdos for higher flow rate applications. Qdos H-FLO aims to make chemical dosing simpler and efficient for operations, maintenance and EHS teams. It offers several onboard communication options for SCADA and PLC integration to achieve process optimisation.”

The Qdos H-FLO is supported with an optional pressure sensing kit that provides real-time pressure monitoring, which ensures process security and improves safety. The optional pressure sensing kit comes with configurable alarms for process monitoring.
