The adoption of multi screw pumps has elevated exponentially over the past half-decade, with the consumption volume rising from 146,000 units in 2015 to 202,000 models in 2022. Antonio Castilhos, vice chairman of nationwide sales, Netzsch Pumps North America, explains what is driving this development.
This rapid rise has been fueled by a quantity of factors, including main development within the industries of finish customers, such as power era, food and beverage, and chemical and petrochemicals. Other reasons include the modernization of the water and wastewater industries, using these pumps in hydraulic fracturing, and the sustained rise of urbanization and industrialization within the creating world.
In addition to growing demand, there might be also a growing awareness and understanding of some nice advantages of multi screw pump technology. Indeed, these applied sciences have benefited from vital enhancements, including new designs and the power to machine within tighter tolerances. Specialized merchandise have additionally become available with various ranges of efficiency for a range of particular applications.
The benefits of multi screw pumps

Multi screw pumps present a wide range of advantages across their numerous applications. First, these pumps are distinguished by their power and working effectivity, resulting in important reductions in power value and value of upkeep. Specifically, Netzsch NOTOS multi screw pumps lead to 23.3% more efficiency when in comparability with other pumps in the marketplace.
These pumps also can deal with a variety of media, including incompressible and highly-viscous products. This contains product that is abrasive, aggressive, corrosive, shear-sensitive, solids laden, low or high viscosity, and lubricating or non-lubricating.
High stress and leak free, the performance of multi screw pumps is consistently high stage. They deal with the conveyed product gently and smoothly, additionally reducing the noise of the method. Because they are totally manufactured from steel, multi screw pumps can also tolerate high temperatures, simply withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are additionally hygienic by design, making them best for purposes in near-sterile environments, corresponding to in the meals, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly straightforward to scrub as a result of they are made from stainless steel and are rigorously polished, such that a pumped product cannot stick with the surfaces. This hygienic design permits for effective cleaning-in-place (CIP) and sterilization-in-place (SIP) processes.
How multi screw pumps work

The working precept of multi screw pumps is inherent in the method by which their interlocking screws transfer the product. These pumps function through a drive spindle that transmits torque to a number of rotating, intermeshing spindles. As these screws rotate, the chambers move repeatedly from the suction aspect to the pressure aspect, successfully conveying the product. This operating principle is what drives the sleek and mild pumping and excessive performance 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 prices and errors, will increase effectivity, and demonstrates top quality. Using เกจ์วัดแรงดันลม (HEUD) idea, NOTOS multi screw pumps are crafted to realize precise tolerances and an optimized spindle profile, ensuring long service life and low life cycle prices. Moreover, the pumps haven’t any axial forces acting on the ball bearing, as they’re hydraulically balanced. This topics the bearings to considerably less stress, minimizing the upkeep required for the pump.
Types of multi screw pumps

Multi screw pumps can be found in two screw, three screw, and 4 screw varieties, each is particularly suitable for a specific set of business purposes. These pumps are the popular alternative of industries including oil and gasoline, maritime and delivery, power era, 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 film. These pumps are ideal for liquids with a range of qualities, from non-abrasive to slightly abrasive, corrosive and non-corrosive, as properly as low to extremely lubricating mediums. The NOTOS 2NS in particular 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 three screw pump that is light-weight and universally applicable with its small footprint, appropriate for applications across industry verticals.
Four screw pumps, or geared twin screw pumps, such because the NOTOS 4NS, have two shafts and four screws. Here, torque is transmitted to the driven shaft by means of helical gears. Being hydraulically balanced, this design prevents steel to metallic contact between single screws, reducing upkeep by appreciable levels and minimizing turbulence. These pumps are used widely throughout industries, reaching common applicability.
Why multi screw pumps are made for modern industry

The optimistic displacement pump with the highest flow price, multi screw pumps are perfect for myriad purposes across trendy trade. The rise of urbanization and industrialization in the creating components of the world and the elevated use of hydraulic fracturing are all factors that account for the elevated use of multi screw pumps.
Moreover, these pumps present immense worth in many of the most technologically advanced endeavors on the planet, including giant scale scientific experiments similar to area simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal position in modern business, Netzsch has been a leading manufacturer of these pumps for many years, having produced these pumps since 1979. Their use of essentially the most superior technology, combined with their decades-long depth of expertise, enables Netzsch to craft pumps with the highest ranges of reliability and sturdiness.
