Pulsation-free progressing cavity pump featuring high precision metering and corrosion resistance

NETZSCH Pumps USA, will be highlighting its complex fluid pumping solutions that are ideal for lithium battery manufacturing at the Advanced Automotive Battery Conference, to be held December 11-14 at the Town & Country Resort, San Diego, CA, Booth 101. Both the NEMO® and PERIPRO® pumps have the ability to transfer complex slurry fluids and provide accurate metered flows of viscous, shear sensitive, and high solids laden materials which makes them well suited for lithium battery production.

NETZSCH NEMO® Progressing Cavity pumps are the best pumping technology solution for the battery manufacturing process and the standard in the industry because of their advanced capabilities. They can convey this industry’s wide range of abrasive slurries and harsh fluids without pulsation and meter them with extremely high precision. No metal-to-metal contact of the pump’s wetted parts and lubrication-free flexible shaft options ensure no contamination of the products. These powerful pumps can also operate at slow speeds supplying very steady, low flows. NEMO® pumps can be provided with many different materials of construction including abrasion resistant hardened steel, ceramic rotors, and one of over 30 stator elastomers. NETZSCH formulates the elastomer compounds in-house to best withstand all of the harsh chemicals and solvents in the liquids.

NEMO® Progressing Cavity Pumps particularly excel in the very demanding electrode coating and slurry mixing applications. For coating applications, these pumps continuously feed even highly viscous slurries with high concentrations of solids in a pulsation-free manner to the coating system achieving the critical thin and uniform coating thickness. The mixing pumps accurately meter the raw materials for a perfect mix to ensure consistent and optimum battery performance. NEMO® pumps also precisely meter or transfer ceramic slurries, electrolytes, adhesives, resins, and many other battery process fluids including those with aggressive solvents.

PERIPRO® Peristaltic Pumps have a heavy duty construction for demanding applications, with heavy duty, precision machined elastomer hoses for +/-1% flow accuracy and large, easy-to-maintain rollers for longer service life. These pumps are ideal for complex slurry fluids, such as abrasive, corrosive, viscous, and shear-sensitive, delicate products, which only come in contact with the elastomer hose. Ultimately, this pump design provides energy savings up to 30%, and requires 90% less lubricant when compared to other peristaltic pumps using sliding shoe design technology.

Among the particular features of PERIPRO® Peristaltic Pumps that make them ideal for lithium battery manufacturing includes the fact that it is a seal-less design, so no hazardous vapors or emissions can escape. Additionally, slurries up to 70% solids are easily conveyed with no exotic, hard alloys required for abrasion resistance. The hose materials have excellent chemical resistance and are available in several elastomeric choices to permit pumping a wide range of fluids containing aggressive chemicals.
