NETZSCH Pumps & Systems India is the leading manufacturer of advanced pumping solutions customized for the unique requirements of lithium battery manufacturing. At the forefront, the NEMO Progressing Cavity pumps, TORNADO Rotary Lobe Pumps, and PERIPRO® Peristaltic pumps can transfer complex electrode slurry fluids and provide accurately metered flows of viscous, shear sensitive, and high solids-laden materials which makes them well suited for lithium battery production.

NEMO® Progressing cavity pumps belong to the group of rotary positive displacement pumps. The main components are a rotating rotor and a stationary stator. The rotor is hinged or elastically attached on one side. The hollow stator is elastic and has the same pitch length as the rotor. 

This leaves conveying spaces between the stator and the rotor, which move continuously from the inlet to the outlet side. The size of the cavities and the associated delivery rate depend on the size of the construction. Except for the rotor and stator, all other components are identical.

 

NETZSCH NEMO® progressing cavity pumps can convey the battery industry’s wide range of abrasive slurries and harsh fluids without pulsation and meter them with extremely high precision. This is applied in the process of feeding, during mixing, grinding, dispersing, and coating or the precise dosing of anode and cathode slurries. 

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. 

Peristatic pumps belong to the group of rotating positive displacement pumps. They only have one wearing part, the hose. The product to be conveyed is forced through the hose by external mechanical deformation of the hose. The hose is supported by the housing of the pump head and is clamped by rollers. The rollers rotate on a rotor. The rotation causes the pinch-off point to move along the hose, thus propelling the pumped product. The elasticity of the hose material generates the suction vacuum. Due to their design, peristaltic pumps are insensitive to dry running.

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. 

Among the particular features of PERIPRO® Peristaltic Pumps that make them ideal for lithium battery manufacturing is 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.
