The Grundfos R&D team collaborates with industry experts to identify, design, develop and test pumps that cater to growing industrial demand.
The textile manufacturing process is highly water intensive. Grundfos provides end-to-end pump solutions based on more than 60 years of experience and designed with special attention to ensure seamless operations in the most critical processes. Across the world, the company pumps are being used for different industrial applications providing lower life cycle costs, high reliability and savings that benefit both users and the environment.
Pump solutions that combine low life cycle costs with reliability and efficiency are user & eco-friendly, and save energy. As the textile industry expands, there is growing concern over the common global problem – water scarcity. There is ever-increasing demand for fresh water, but improper disposal of wastewater or poor wastewater management threatens the existing water sources. To address this hazardous situation, the Government and the State Pollution Board have enforced stringent rules and regulations on the industry to ensure effective wastewater management.
Efforts would go into setting up expensive common effluent treatment plants (CETPs) and other measures to ensure that business functionality is not affected by the need to be environmentally sensitive. Grundfos produces pumps, mixers, flow makers and diffusers that are eco-sensitive and reliable, considerably helping customers save water.
Tirupur is one of the largest textile manufacturing hubs in India. With rising business demand, there is growing concern over discharge of effluent that pollutes the waterbed, leading to the Pollution Control Board setting stringent norms to check the menace. As a solutions provider, Grundfos supplies pumps, mixers, flow makers, diffusers and dosing systems for different industries in Tirupur to help them in their endeavour to reduce environmental degradation.
The numerous processes in the textile industry invariably leave the effluent at the end of the cycle that needs to be handled efficiently. As the effluents are corrosive, acidic and are chemically different due to the varying processes involved, Grundfos has developed and executed various projects with a proven submersible range of pumps. These pumps also come with unique features like energy retrieval considering the efficiency loss due to increased clearances.
Dyeing and finishing
Dyeing and finishing is an important process that consumes the highest amount of water. Grundfos has specially designed pumps that cater to the large water demands while remaining conscious of the need to ensure that every drop of water is put to its best use.
At one of the customer installations in Tirupur, Grundfos has set up the Hydro 1000 system to take care of the fluctuating demand. This customer has 15 soft flow dyeing machines. Each machine has a tank to be filled for 20 cycles. In each cycle the tank has to be filled up thrice within the shortest possible time. The earlier system had a single pump with the throttle mechanism.
The new Grundfos pumps ensure ease and trouble-free operation and, most importantly, availability of spares and service on time. At another customer location in Bangalore, the company has installed the Hydro-2000 4 X CR 64-3 MF system in the main distribution line. This customer with two soft dyeing machines plans to add a few more. In a dyeing unit, the soft flow dyeing machine requires smooth flow of water during fluctuating demand. Water needs to be filled in the dyeing vessel in the shortest possible time. Grundfos installed a ‘fit & forget’ technology to one of the critical processes in the textile industry which is highly reliable and energy saving system to the customer.
At another customer installation in Tirupur, the company has provided its digital dosing pump as replacement to the existing conventional dosing pump. Normally fabric processing includes bleaching / dyeing depending on the colour of the fabric. The customer earlier had imported bleaching machines with dosing pumps of solenoid type which called for mechanical adjustment of stroke length and frequency. This caused a lot of imprecision. The Grundfos system installed now is compact and is focused on precision and trouble-free operation.
