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.

Challenge Faced:

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
