The adoption of multi screw pumps has increased exponentially over the past half-decade, with the consumption volume rising from 146,000 units in 2015 to 202,000 units in 2022. Antonio Castilhos, vp of nationwide sales, Netzsch Pumps North America, explains what is driving this development.
This rapid rise has been fueled by numerous elements, together with major progress in the industries of finish users, corresponding to power technology, food and beverage, and chemical and petrochemicals. Other reasons embody the modernization of the water and wastewater industries, the utilization of these pumps in hydraulic fracturing, and the sustained rise of urbanization and industrialization in the growing world.
In addition to increasing demand, there might be additionally a rising awareness and understanding of the advantages of multi screw pump know-how. Indeed, these applied sciences have benefited from vital enhancements, including new designs and the power to machine inside tighter tolerances. Specialized merchandise have also turn into out there with varying ranges of performance for a range of particular functions.
The advantages of multi screw pumps
Multi screw pumps present a variety of benefits throughout their various applications. First, these pumps are distinguished by their vitality and working effectivity, leading to significant reductions in energy cost and cost of upkeep. Specifically, Netzsch NOTOS multi screw pumps lead to 23.3% more efficiency when compared to other pumps on the market.
These pumps can even deal with a variety of media, together with incompressible and highly-viscous merchandise. This contains 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 persistently high level. They deal with the conveyed product gently and easily, also decreasing the noise of the method. Because they’re totally made from steel, multi screw pumps also can tolerate excessive temperatures, easily withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are also hygienic by design, making them perfect for applications in near-sterile environments, similar to within the food, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly simple to clean because they are manufactured from stainless 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 manner by which their interlocking screws move the product. These pumps operate via a drive spindle that transmits torque to multiple rotating, intermeshing spindles. As these screws rotate, the chambers move constantly from the suction side to the strain facet, successfully conveying the product. This working principle is what drives the graceful and delicate pumping and high performance of screw pumps.
The importance of precision machining in manufacturing multi screw pumps
Precision machining is imperative for modern manufacturing. It ensures efficient and easy manufacturing, reduces prices and errors, increases effectivity, and demonstrates high quality. Using the High Efficiency Unique Design (HEUD) idea, NOTOS multi screw pumps are crafted to realize precise tolerances and an optimized spindle profile, ensuring lengthy service life and low life cycle costs. Moreover, the pumps haven’t any axial forces appearing on the ball bearing, as they are hydraulically balanced. This topics the bearings to significantly much less stress, minimizing the upkeep required for the pump.

Multi screw pumps are available in two screw, three screw, and four screw varieties, every is especially appropriate for a particular set of business applications. These pumps are the popular selection of industries together with oil and gas, maritime and transport, energy 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 perfect for liquids with a variety of qualities, from non-abrasive to barely abrasive, corrosive and non-corrosive, as nicely as low to highly lubricating mediums. The NOTOS 2NS specifically is distinguished by its long service life when conveying non-abrasive to barely abrasive product.
Three screw pumps are designed with two rotating, intermeshing driven 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 relevant with its small footprint, appropriate for purposes throughout trade verticals.
Four screw pumps, or geared twin screw pumps, such because the NOTOS 4NS, have two shafts and 4 screws. Here, torque is transmitted to the driven shaft by means of helical gears. Being hydraulically balanced, this design prevents steel to steel contact between single screws, decreasing maintenance by considerable degrees and minimizing turbulence. These pumps are used extensively throughout industries, attaining common applicability.
Why multi screw pumps are made for contemporary business
The positive displacement pump with the highest circulate price, multi screw pumps are perfect for myriad applications throughout trendy industry. The rise of urbanization and industrialization within the growing components of the world and the elevated use of hydraulic fracturing are all components that account for the increased use of multi screw pumps.
Moreover, these pumps present immense worth in lots of the most technologically advanced endeavors on the planet, together with giant scale scientific experiments corresponding to house simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal function in trendy trade, Netzsch has been a quantity one producer of those pumps for decades, having produced these pumps since 1979. Their use of essentially the most advanced technology, mixed with their decades-long depth of experience, enables Netzsch to craft pumps with the best ranges of reliability and durability.
