The adoption of multi screw pumps has increased exponentially over the past half-decade, with the consumption volume rising from 146,000 items in 2015 to 202,000 units in 2022. Antonio Castilhos, vice president of national gross sales, Netzsch Pumps North America, explains what is driving this development.
This fast rise has been fueled by a number of elements, including major progress in the industries of finish users, corresponding to energy era, food and beverage, and chemical and petrochemicals. Other reasons embody 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 increasing demand, there’s also a rising consciousness and understanding of some nice advantages of multi screw pump know-how. Indeed, these technologies have benefited from significant enhancements, together with new designs and the flexibility to machine inside tighter tolerances. Specialized merchandise have additionally turn into obtainable with varying ranges of performance for a variety of specific applications.
The advantages of multi screw pumps

Multi screw pumps present a broad range of benefits across their varied functions. First, these pumps are distinguished by their power and working efficiency, leading to significant reductions in vitality price and price of upkeep. Specifically, Netzsch NOTOS multi screw pumps lead to 23.3% extra effectivity when in comparability with different pumps on the market.
pressure gauge can also deal with a variety of media, together with incompressible and highly-viscous products. This consists of product that’s abrasive, aggressive, corrosive, shear-sensitive, solids laden, low or high viscosity, and lubricating or non-lubricating.
High pressure and leak free, the performance of multi screw pumps is consistently excessive level. They handle the conveyed product gently and easily, also lowering the noise of the process. Because they’re entirely made from steel, multi screw pumps also can tolerate excessive temperatures, simply withstanding temperatures above 572° Fahrenheit / 300° Celsius.
Multi screw pumps are additionally hygienic by design, making them best for applications in near-sterile environments, similar to within the food, beverage, pharmaceutical, and cosmetics industries. These pumps are fairly simple to scrub because they’re made of chrome steel and are rigorously polished, such that a pumped product can’t stick with the surfaces. This hygienic design allows for effective cleaning-in-place (CIP) and sterilization-in-place (SIP) processes.
How multi screw pumps work

The working principle of multi screw pumps is inherent within the method by which their interlocking screws move the product. These pumps perform by way of a drive spindle that transmits torque to a quantity of rotating, intermeshing spindles. As these screws rotate, the chambers move repeatedly from the suction side to the stress aspect, effectively conveying the product. This operating precept is what drives the graceful and gentle pumping and high performance of screw pumps.
The importance of precision machining in manufacturing multi screw pumps

Precision machining is crucial for modern manufacturing. It ensures efficient and clean production, reduces prices and errors, will increase effectivity, and demonstrates top of the range. Using the High Efficiency Unique Design (HEUD) idea, NOTOS multi screw pumps are crafted to attain precise tolerances and an optimized spindle profile, guaranteeing lengthy service life and low life cycle prices. Moreover, the pumps don’t have any axial forces performing on the ball bearing, as they are hydraulically balanced. This subjects the bearings to considerably much less stress, minimizing the maintenance required for the pump.
Types of multi screw pumps

Multi screw pumps can be found in two screw, three screw, and 4 screw varieties, every is especially appropriate for a specific set of business applications. These pumps are the popular alternative of industries together with oil and fuel, maritime and transport, energy 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 via a hydrodynamic movie. These pumps are good for liquids with a range of qualities, from non-abrasive to barely abrasive, corrosive and non-corrosive, in addition to low to highly 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 effective at conveying non-abrasive and non-corrosive product, along with liquids with low to medium viscosity. diaphragm seal is a three screw pump that’s light-weight and universally applicable 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 4 screws. Here, torque is transmitted to the pushed shaft by the use of helical gears. Being hydraulically balanced, this design prevents metallic to steel contact between single screws, reducing upkeep by considerable degrees and minimizing turbulence. These pumps are used broadly throughout industries, attaining common applicability.
Why multi screw pumps are made for modern business

The positive displacement pump with the highest flow fee, multi screw pumps are best for myriad applications throughout trendy industry. The rise of urbanization and industrialization within the developing components of the world and the increased use of hydraulic fracturing are all components that account for the increased use of multi screw pumps.
Moreover, these pumps present immense value in lots of the most technologically advanced endeavors on the earth, together with large scale scientific experiments corresponding to house simulation chambers, gravitational wave detectors, and ultra-high vacuum chambers.
While multi screw pumps play a pivotal position in fashionable industry, Netzsch has been a quantity one producer 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.
