Watson-Marlow Fluid Technology Solutions (WMFTS) is highlighting its range of Bredel and Bredel APEX hose pumps for manufacturing processes used in producing lithium-ion batteries for EVs. The company says they provide constant production cycle efficiency and help manufacturers to meet ever-more demanding battery production schedules.

The Bredel pumps are said to be ideal for the ball milling process used in manufacturing lithium iron phosphate batteries. Unlike older, air-operated double-diaphragm pump technology, the pumps are not affected by slurry viscosity, which ensures greater production cycle efficiency.

The pumps run at 20 revolutions per minute in continuous 24/7 operation as part of a computer-controlled process. They also reduce wear to the ball/seats, which can result in leakage, causing increased downtime and repair costs.

The APEX hose pumps are for transferring liquid chemicals from raw material tanks to reaction tanks at stable flow rates for the production of battery-grade cobalt tetroxide and high-purity battery-grade cobalt sulphate. They are designed to operate 24 hours a day for 7-10 days and are supplied with optimum hose elements.

With their seal-less, valve-less design, WMFTS says the APEX pumps are engineered for a more competitive price/performance ratio in comparison with high-pressure hose pumps, and are designed to suit all dosing, metering and transfer applications.
