Exchange of screw pumps
The KREISEL high-pressure rotary valve is one of the most commonly used systems for feeding bulk materials into pneumatic conveying lines.
Thanks to its state-of-the-art technology, it offers a highly energy-efficient alternative to traditional screw pumps. By reducing motor power consumption, the system significantly lowers energy usage, which reduces both operational costs and environmental impact.
The replacement of the screw pump against the KREISEL high-pressure rotary valve is very simple and time-saving and can be done with minimal modifications on the feeding system. By adjusting the screw pump’s de-dusting box, the rotary valve can easily be connected to the existing de-dusting bin. The conveying air compressor or blower, as well as the conveying pipe, remain mostly unchanged. KREISEL provides all the necessary information for the modification and supports our customers from measurement to commissioning.
On the right, a screw pump was replaced by a KREISEL rotary valve. The left screw pump now only serves as a standby pump.
A further advantage of the KREISEL ceramic rotary valve is the lower installation height as shown in the picture for a feeding capacity of 50 t/h of cement:
• Cost savings up to 95% due to energy reduction
• Reduction of CO2 emissions
• High reliability due to wear protection
• Quadruple life circle due to symmetrical design (3 times turnable)
• Regrindable or exchangeable ceramic parts
• Simple installation & short commissioning times
• Unbeatable low maintenance
• Low investment costs
Range of application: | Fine, non-baking materials and dusts |
