CHEMICAL AND PHARMACEUTICAL INDUSTRY

High key laboratory glassware filled with various coloured liquids

 

The chemical and also the pharmaceutical Industry became one of the most important Industries worldwide. This covers a wide spectrum of products which have to be conveyed.

The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials (oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products

The pharmaceutical industry discovers, develops, produces, and markets drugs or pharmaceutical drugs

 

 

 

The use of single-screw pumps in the chemical sector is quite extensive. These pumps are valued for their ability to handle a wide range of fluids, including corrosive, abrasive, and viscous substances commonly found in chemical processing. They operate on a simple principle: a single rotating screw inside a cylindrical cavity, which moves the fluid along the screw’s axis.

In chemical applications, single-screw pumps are employed for various purposes, including transferring chemicals between processing stages, circulating liquids within reactors or tanks, and metering precise amounts of substances into production lines. Their design minimizes shear and turbulence, making them suitable for handling delicate or shear-sensitive fluids without compromising their integrity.

Moreover, single-screw pumps are often preferred in situations requiring high reliability and efficiency. They are known for their robust construction and low maintenance requirements, which are critical factors in industrial settings where downtime can be costly. Additionally, their ability to operate at high pressures and temperatures makes them versatile for use in diverse chemical processes.

Overall, the utilization of single-screw pumps in the chemical industry underscores their importance in facilitating smooth and efficient operations while ensuring the safe handling of various chemicals and fluids.
