The increasing use of multi screw pumps in modern industry

The adoption of multi screw pumps has increased exponentially over the previous half-decade, with the consumption volume rising from 146,000 units in 2015 to 202,000 items in 2022. Antonio Castilhos, vice president of national sales, Netzsch Pumps North America, explains what is driving this development.
This fast rise has been fueled by numerous components, including major development in the industries of end users, such as energy generation, food and beverage, and chemical and petrochemicals. Other reasons 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 creating world.
In addition to rising demand, there’s additionally a growing awareness and understanding of the advantages of multi screw pump expertise. Indeed, these technologies have benefited from vital improvements, together with new designs and the flexibility to machine within tighter tolerances. Specialized products have also turn into available with varying levels of efficiency for a range of particular applications.
The advantages of multi screw pumps
Multi screw pumps provide a variety of advantages across their numerous applications. First, these pumps are distinguished by their energy and operating effectivity, resulting in vital reductions in power price and cost of maintenance. Specifically, Netzsch NOTOS multi screw pumps result in 23.3% extra effectivity when in comparability with different pumps on the market.
These pumps also can handle a wide range of media, including incompressible and highly-viscous merchandise. This consists of product that’s abrasive, aggressive, corrosive, shear-sensitive, solids laden, low or excessive viscosity, and lubricating or non-lubricating.
High pressure and leak free, the performance of multi screw pumps is persistently excessive stage. They handle the conveyed product gently and easily, additionally reducing the noise of the process. Because they are totally 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 best for functions in near-sterile environments, corresponding to in the meals, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly simple to clean as a result of they’re manufactured from stainless steel and are rigorously polished, such that a pumped product cannot stick with the surfaces. Authentic allows 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 manner by which their interlocking screws transfer the product. These pumps perform through a drive spindle that transmits torque to multiple rotating, intermeshing spindles. As these screws rotate, the chambers transfer repeatedly from the suction facet to the pressure aspect, successfully conveying the product. This operating precept is what drives the graceful and gentle pumping and excessive efficiency of screw pumps.
The importance of precision machining in manufacturing multi screw pumps
Precision machining is crucial for contemporary manufacturing. It ensures effective and smooth manufacturing, reduces prices and errors, increases efficiency, and demonstrates high quality. Using the High Efficiency Unique Design (HEUD) idea, NOTOS multi screw pumps are crafted to achieve precise tolerances and an optimized spindle profile, making certain lengthy service life and low life cycle costs. Moreover, the pumps don’t have any axial forces appearing on the ball bearing, as they’re hydraulically balanced. This subjects 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 especially suitable for a selected set of industry applications. These pumps are the preferred choice of industries including oil and gas, maritime and transport, power era, course of industries, tank farms, and petrochemicals.
A two screw pump, the NOTOS 2NS has one drive screw that transfers torque to the rotating intermeshing driven screw by way of a hydrodynamic movie. These pumps are excellent for liquids with a variety of qualities, from non-abrasive to slightly abrasive, corrosive and non-corrosive, in addition to low to extremely lubricating mediums. The NOTOS 2NS specifically 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 efficient at conveying non-abrasive and non-corrosive product, along with liquids with low to medium viscosity. The NOTOS 3NS is a three screw pump that is lightweight and universally relevant with its small footprint, appropriate for purposes throughout industry verticals.
Four screw pumps, or geared twin screw pumps, such as the NOTOS 4NS, have two shafts and four screws. Here, torque is transmitted to the driven shaft by method of helical gears. Being hydraulically balanced, this design prevents steel to steel contact between single screws, reducing upkeep by considerable levels and minimizing turbulence. These pumps are used extensively throughout industries, achieving universal applicability.
Why multi screw pumps are made for contemporary trade
The constructive displacement pump with the very best circulate rate, multi screw pumps are ideal for myriad purposes throughout trendy trade. The rise of urbanization and industrialization within the developing parts 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 provide immense worth in lots of the most technologically superior endeavors on the earth, together with massive scale scientific experiments corresponding to area simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal function in modern industry, Netzsch has been a quantity one manufacturer of those pumps for decades, having produced these pumps since 1979. Their use of essentially the most advanced technology, combined with their decades-long depth of expertise, permits Netzsch to craft pumps with the highest levels of reliability and durability.
