1. Product Introduction

The Vertical Portable Screw Pump is a compact, efficient, and mobile Progressive cavity pump designed for transferring viscous, abrasive, or shear-sensitive materials across a wide range of industries. Unlike traditional stationary pumps, this model features a vertical design with a portable structure, allowing users to easily move and operate it wherever fluid transfer is required — from storage tanks to mixing vessels, trucks, or processing lines.

This pump operates on the progressive cavity principle, in which a single helical rotor rotates within a double helical elastomer stator. As the rotor turns, sealed cavities form and progress continuously from the suction side to the discharge side, ensuring a smooth, pulsation-free, and low-shear flow. This makes it ideal for handling delicate or sensitive materials such as honey, cream, paint, sludge, glue, and food pastes.

Constructed with stainless steel (304 or 316L) for the wetted parts, the Vertical Portable Screw Pump meets sanitary and industrial standards, making it suitable for use in food, pharmaceutical, cosmetic, and chemical industries. The portable frame with built-in handles or wheels allows easy relocation and quick connection to multiple process points, significantly improving productivity and flexibility.

Equipped with a frequency-controlled motor, the pump can easily adjust flow rate and pressure according to process needs. It offers quiet operation, easy maintenance, and long service life, making it an essential solution for mobile fluid transfer systems, temporary installations, or maintenance bypass lines.
