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, vp of national sales, Netzsch Pumps North America, explains what’s driving this growth.
This rapid rise has been fueled by a quantity of factors, together with main development in the industries of end users, similar to energy technology, 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 rising demand, there is additionally a rising consciousness and understanding of some nice benefits of multi screw pump technology. Indeed, these applied sciences have benefited from significant enhancements, together with new designs and the ability to machine within tighter tolerances. Specialized products have additionally turn out to be available with various ranges of performance for a range of particular applications.
The advantages of multi screw pumps
Multi screw pumps present a variety of advantages throughout their varied functions. First, these pumps are distinguished by their vitality and operating effectivity, leading to important reductions in vitality value and cost of upkeep. Specifically, Netzsch NOTOS multi screw pumps result in 23.3% more effectivity when in comparison with different pumps available on the market.
These pumps can also deal with a broad range of media, including incompressible and highly-viscous products. This includes product that is abrasive, aggressive, corrosive, shear-sensitive, solids laden, low or excessive viscosity, and lubricating or non-lubricating.
High pressure and leak free, the efficiency of multi screw pumps is constantly excessive degree. They handle the conveyed product gently and smoothly, also reducing the noise of the method. Because they’re entirely manufactured from steel, multi screw pumps can even tolerate high temperatures, easily withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are additionally hygienic by design, making them ideal for applications in near-sterile environments, corresponding to in the meals, beverage, pharmaceutical, and cosmetics industries. These pumps are quite straightforward to wash as a outcome of they are manufactured from chrome steel and are rigorously polished, such that a pumped product cannot stick to 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 precept of multi screw pumps is inherent within the method by which their interlocking screws move the product. These pumps operate through a drive spindle that transmits torque to multiple rotating, intermeshing spindles. As these screws rotate, the chambers transfer repeatedly from the suction side to the pressure facet, effectively conveying the product. This working precept is what drives the sleek and delicate pumping and excessive efficiency of screw pumps.
The significance of precision machining in manufacturing multi screw pumps
Precision machining is imperative for modern manufacturing. It ensures efficient and clean production, reduces prices and errors, increases efficiency, and demonstrates top of the range. 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 costs. Moreover, the pumps don’t have any axial forces appearing on the ball bearing, as they are 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 can be found in two screw, three screw, and four screw varieties, each is especially appropriate for a selected set of industry functions. These pumps are the popular choice of industries including oil and gas, maritime and shipping, energy 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 driven screw via a hydrodynamic film. These pumps are excellent for liquids with a range of qualities, from non-abrasive to slightly abrasive, corrosive and non-corrosive, as nicely as low to extremely 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, along with liquids with low to medium viscosity. The NOTOS 3NS is a 3 screw pump that’s light-weight and universally applicable with its small footprint, appropriate for applications across trade 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 method of helical gears. Being hydraulically balanced, this design prevents steel to steel contact between single screws, reducing maintenance by appreciable levels and minimizing turbulence. These pumps are used extensively across industries, achieving universal applicability.
Why multi screw pumps are made for modern industry
The positive displacement pump with the best circulate price, multi screw pumps are perfect for myriad purposes throughout trendy industry. Copy of urbanization and industrialization in 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 value in lots of the most technologically superior endeavors in the world, together with large scale scientific experiments corresponding to space simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal position in modern trade, Netzsch has been a quantity one manufacturer of these pumps for many years, having produced these pumps since 1979. Their use of essentially the most advanced know-how, combined with their decades-long depth of expertise, enables Netzsch to craft pumps with the best levels of reliability and sturdiness.
