The adoption of multi screw pumps has increased exponentially over the past half-decade, with the consumption quantity rising from 146,000 items in 2015 to 202,000 models in 2022. Antonio Castilhos, vp of national gross sales, Netzsch Pumps North America, explains what’s driving this development.
This fast rise has been fueled by numerous components, including main development within the industries of end customers, such as energy technology, meals and beverage, and chemical and petrochemicals. Other reasons embody the modernization of the water and wastewater industries, the use of these pumps in hydraulic fracturing, and the sustained rise of urbanization and industrialization within the growing world.
In addition to increasing demand, there is additionally a rising awareness and understanding of the advantages of multi screw pump technology. Indeed, these applied sciences have benefited from significant enhancements, together with new designs and the flexibility to machine inside tighter tolerances. Specialized products have additionally become obtainable with various levels of performance for a spread of specific purposes.
The advantages of multi screw pumps
Multi screw pumps provide a variety of benefits throughout their varied applications. First, these pumps are distinguished by their energy and operating effectivity, resulting in significant reductions in energy price and value of upkeep. Specifically, Netzsch NOTOS multi screw pumps lead to 23.3% extra effectivity when in comparability with different pumps on the market.
These pumps also can deal with a extensive range of media, including incompressible and highly-viscous merchandise. This includes 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 constantly excessive degree. They deal with the conveyed product gently and easily, also decreasing the noise of the process. Because they are completely made of metallic, multi screw pumps can also tolerate high temperatures, easily withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are also hygienic by design, making them best for purposes in near-sterile environments, corresponding to in the food, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly easy to clean as a result of they are made of stainless-steel and are rigorously polished, such that a pumped product can not persist with the surfaces. This hygienic design permits 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 transfer the product. These pumps perform by way of 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, effectively conveying the product. This working principle is what drives the sleek and mild pumping and high efficiency of screw pumps.
The significance of precision machining in manufacturing multi screw pumps
Precision machining is imperative for contemporary manufacturing. It ensures effective and smooth production, reduces prices and errors, increases efficiency, and demonstrates top quality. Using the High Efficiency Unique Design (HEUD) concept, NOTOS multi screw pumps are crafted to attain precise tolerances and an optimized spindle profile, ensuring lengthy service life and low life cycle costs. Moreover, the pumps don’t have any axial forces performing on the ball bearing, as they are hydraulically balanced. This subjects the bearings to significantly much less stress, minimizing the maintenance 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 trade purposes. These pumps are the preferred choice of industries together with oil and gas, maritime and shipping, power technology, 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 pushed screw by way of a hydrodynamic movie. These pumps are ideal for liquids with a variety of qualities, from non-abrasive to barely abrasive, corrosive and non-corrosive, as properly as low to highly lubricating mediums. The NOTOS 2NS specifically is distinguished by its long service life when conveying non-abrasive to slightly 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’s lightweight and universally applicable with its small footprint, suitable for applications across trade 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 metallic to steel contact between single screws, lowering maintenance by appreciable levels and minimizing turbulence. These pumps are used extensively across industries, attaining common applicability.

The constructive displacement pump with the highest flow rate, multi screw pumps are best for myriad applications across trendy trade. The rise of urbanization and industrialization within the creating components of the world and the elevated use of hydraulic fracturing are all elements that account for the increased use of multi screw pumps.
Moreover, these pumps present immense worth in lots of the most technologically superior endeavors in the world, together with massive scale scientific experiments such as space simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal role in modern trade, Netzsch has been a number one producer of those pumps for decades, having produced these pumps since 1979. Their use of essentially the most superior know-how, combined with their decades-long depth of experience, enables Netzsch to craft pumps with the highest levels of reliability and durability.
