The rising use of multi screw pumps in trendy trade

The adoption of multi screw pumps has elevated exponentially over the previous half-decade, with the consumption volume rising from 146,000 units in 2015 to 202,000 models in 2022. Antonio Castilhos, vice chairman of national sales, Netzsch Pumps North America, explains what’s driving this progress.
This fast rise has been fueled by a number of components, including major progress within the industries of finish users, similar to energy technology, food and beverage, and chemical and petrochemicals. Other causes include the modernization of the water and wastewater industries, the use of these pumps in hydraulic fracturing, and the sustained rise of urbanization and industrialization in the developing world.
In addition to rising demand, there might be additionally a growing consciousness and understanding of the benefits of multi screw pump technology. Indeed, these technologies have benefited from significant improvements, including new designs and the flexibility to machine inside tighter tolerances. Specialized products have additionally turn into out there with varying ranges of efficiency for a range of particular applications.
The advantages of multi screw pumps
Multi screw pumps provide a broad range of advantages throughout their various purposes. First, these pumps are distinguished by their power and working efficiency, resulting in important reductions in vitality value and cost of upkeep. Specifically, Netzsch NOTOS multi screw pumps result in 23.3% more efficiency when in comparability with other pumps available on the market.
These pumps can even deal with a variety of media, together with incompressible and highly-viscous merchandise. This includes product that’s abrasive, aggressive, corrosive, shear-sensitive, solids laden, low or high viscosity, and lubricating or non-lubricating.

Because they are entirely made from metal, multi screw pumps can even tolerate high temperatures, simply withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are additionally hygienic by design, making them perfect for functions in near-sterile environments, corresponding to within the food, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly simple to wash as a end result of they’re made from chrome steel and are rigorously polished, such that a pumped product can’t stick with the surfaces. This hygienic design allows for efficient cleaning-in-place (CIP) and sterilization-in-place (SIP) processes.
How multi screw pumps work
The working principle of multi screw pumps is inherent within the manner by which their interlocking screws move the product. These pumps perform by way of a drive spindle that transmits torque to a number of rotating, intermeshing spindles. As these screws rotate, the chambers move constantly from the suction facet to the pressure side, successfully conveying the product. This working precept is what drives the graceful and mild pumping and excessive efficiency of screw pumps.
The importance of precision machining in manufacturing multi screw pumps
Precision machining is imperative for contemporary manufacturing. It ensures efficient and easy manufacturing, reduces costs and errors, will increase efficiency, and demonstrates high quality. Using the High Efficiency Unique Design (HEUD) concept, NOTOS multi screw pumps are crafted to achieve exact tolerances and an optimized spindle profile, making certain lengthy service life and low life cycle prices. Moreover, the pumps don’t have any axial forces acting on the ball bearing, as they’re hydraulically balanced. This subjects the bearings to considerably much less stress, minimizing the upkeep required for the pump.
Types of multi screw pumps
Multi screw pumps are available in two screw, three screw, and four screw varieties, every is especially appropriate for a selected set of industry purposes. These pumps are the popular alternative of industries including oil and gas, maritime and shipping, power technology, process industries, tank farms, and petrochemicals.
A two screw pump, the NOTOS 2NS has one drive screw that transfers torque to the rotating intermeshing pushed screw by way of a hydrodynamic movie. These pumps are best for liquids with a spread of qualities, from non-abrasive to slightly abrasive, corrosive and non-corrosive, as properly as low to highly lubricating mediums. The NOTOS 2NS particularly is distinguished by its lengthy service life when conveying non-abrasive to barely abrasive product.
Three screw pumps are designed with two rotating, intermeshing pushed screws. Three screw pumps are effective at conveying non-abrasive and non-corrosive product, in addition to liquids with low to medium viscosity. The NOTOS 3NS is a 3 screw pump that is light-weight and universally applicable with its small footprint, suitable for purposes throughout industry verticals.
Four screw pumps, or geared twin screw pumps, such as the NOTOS 4NS, have two shafts and 4 screws. Here, torque is transmitted to the pushed shaft by the use of helical gears. Being hydraulically balanced, this design prevents steel to steel contact between single screws, lowering upkeep by appreciable degrees and minimizing turbulence. These pumps are used extensively across industries, reaching universal applicability.
Why multi screw pumps are made for modern trade
The optimistic displacement pump with the very best move rate, multi screw pumps are best for myriad functions across modern industry. The rise of urbanization and industrialization within the growing parts of the world and the increased use of hydraulic fracturing are all factors that account for the increased use of multi screw pumps.
Moreover, these pumps present immense worth in most of the most technologically superior endeavors in the world, including giant scale scientific experiments corresponding to area simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal position in modern industry, Netzsch has been a leading producer of these pumps for decades, having produced these pumps since 1979. Their use of probably the most superior technology, combined with their decades-long depth of expertise, allows Netzsch to craft pumps with the highest ranges of reliability and durability.
