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. 

When selecting chemical dosing pumps for specific applications, it is crucial to consider several factors to ensure the efficient and safe delivery of chemicals. In the dynamic landscape of industrial processes, precise and efficient chemical dosing is a critical element for ensuring optimal performance and safety.

Here is a guide to help you make a clever selection:

Chemical Compatibility: 

Understand the chemical properties of the substances you intend to dispense. Choose a pump material that is compatible with the chemical being used to prevent corrosion or damage.

Flow Rate and Pressure Requirements: 

Determine the required flow rate and pressure for your application. Select a pump that can handle the specific flow rate and pressure demands of your system to ensure accurate dosing.

Accuracy and Precision:

For applications that require precise dosing, choose a pump that offers high accuracy and repeatability to avoid over or under-dosing.

Control Options: 

Consider the control options available for the pump, such as manual, automatic, or programmable control, depending on the complexity of your dosing requirements.

Environmental Conditions:

Assess the environmental conditions, including temperature, humidity, and potential exposure to external elements. Select a pump that can operate effectively within the specified conditions.

Maintenance and Service Requirements: 

Evaluate the ease of maintenance and service requirements for the pump. Choose a pump that is easy to maintain and service to minimize downtime and operational costs.

Safety Measures: Prioritize pumps equipped with safety features such as leak detection, overload protection, and pressure relief valves to ensure the safety of personnel and the surrounding environment.

Cost Considerations: Balance the initial investment with the long-term operating costs. Consider the total cost of ownership, including energy consumption, maintenance, and replacement parts, to make an informed decision.

Reputation and Support: Research the reputation of the manufacturer and supplier. Opt for reputable brands that offer reliable customer support and after-sales services to address any issues or concerns that may arise.

Compliance with Industry Standards: Ensure that the selected pumps comply with relevant industry standards and regulations to maintain the integrity of your processes and meet legal requirements.

By considering these factors, you can make an informed decision and select the most suitable chemical dosing pump for your specific applications, ensuring optimal performance and safety.

Different types of chemical solvents are used in the Paint, Pigments, and Ink industry. NETZSCH pumps are designed for accurate metering and dosing and also ensure gentle and consistent flow.

Problem Identification

Paint manufacturing companies are struggling with a common problem, which is the repeated breakdown of their pumps used in the process of refilling offset ink from the transport truck to the storage tank. In most cases, the pumps engaged here are diaphragm pumps.

Because of such inadequacies, the unloading process was greatly delayed and the pumps needed a high amount of maintenance work, often requiring them to be removed completely and dismantled, which was a labor-intensive and time-consuming task.

The application requirements in the industry were for the spin flash dryer (to reduce moisture content in pigment-dewatered sludge cake). Feeding the dewatered sludge into the spin flash dryer, by a system that can give the required flow rate can transfer the thick viscous medium at an elevation of 8 – 10 meters and must be compact in size.

During initial testing which was done for a few minutes, the pump’s motor was tripping due to the dry running of the pump.

Due to the sticky nature of the material, the pump was getting choked thereby restricting the movement of the fluid, resulting in choking of the pump.

NETZSCH SOLUTION

Why Progressive cavity pump?

To increase the performance, economy, and reliability of the sludge handling system, the company decided to contact the pumping experts at NETZSCH Pumps & Systems to get a suitable solution.

On reviewing the problem, the NETZSCH NEMO® Progressing Cavity Pumps, a single-stage pump model with a BP module allowing for a higher delivery rate at a lower differential pressure was proposed and offered as our solution.

This system prevented excessive clamping thereby improving mechanical efficiency. Allowed space for multiple pump installations, due to compact nature. Enabled easy access to the devices in case maintenance work had to be carried out. Operated more reliably and efficiently than the previously employed diaphragm pumps, which resulted in the reduction of the unloading time for the ink by less than half of the time consumed earlier.

Other applications within the Paints, pigments, and ink industry facing similar challenges with fluid handling are:

• Filter press feeding (pigments & dyes)
• Spray dryer feeding (Highly acidic dyes & solvent-based dyes)
• Tank-to-tank transfer – NEMO / Tornado

NETZSCH Pumps in Plywood Manufacturing

NEMO is used in two different application sections in the plywood manufacturing process as follows:

Defibration Process: 

Before the Defibration process, the chips are coated with molten paraffin wax or emulsifiers. The coating of wax or emulsifier is done by using NEMO.

Blow line: 

From the deliberator, the pulp enters a blow line, where it is mixed with prepared glue. In this process, NEMO is used in feeding the prepared glue into the blow line.

Why Progressive cavity pump?

Other pumping technologies used in the process of making plywood are as follows.

1. Diaphragm pump
2. Gear pump

While using a diaphragm pump in the coating of wax or emulsifier they had an issue of pulsation. Causes of Pulsation are as follows:

 * Nonuniform coating of wax or emulsifier in the pulp thus reduces the moisture handling capacity of the plywood.

 *Vibration in the pipeline and thus creates leaks in the connection ports.

Gear pumps also can be used to transfer the coloring agent, additives, resin, fungicides, etc., into the glue preparation tank. Here there are chances to shear the product and thus can lead to the chemical and physical property change of the fluid.

Also, there could be a seal leak issue in the resin and additive line.

The blow line has a line pressure of 12 bar, the pump has to work against this pressure and inline dosing of prepared glue to be done without any pulsation. Hence customer is using PCP to get a constant flow against the line pressure.
