In industrial fluid handling applications, the efficient transfer of viscous liquids presents unique challenges that conventional centrifugal pumps often struggle to overcome. Single-screw pumps, also known as progressive cavity pumps, have emerged as a superior solution for handling viscous fluids across numerous industries. These positive displacement pumps offer exceptional performance characteristics when dealing with thick, sticky, or non-Newtonian fluids that would cause problems for other pump types. This paper examines the operational principles of single-screw pumps, their advantages in viscous liquid applications, key design features that enhance performance, and their diverse industrial applications where viscous fluid handling is critical.

The stator is a critical component of electric motors, responsible for generating a rotating magnetic field that interacts with the rotor to produce motion. The choice of stator material significantly impacts motor performance, efficiency, durability, and compatibility with different operating fluids.
