Specially designed miniature screw pumps feature variable delivery, strong self-priming capabilities, reversibility, and the ability to transport liquids containing solid particles. They are widely used in the pharmaceutical, food, and cosmetics industries. They can transport a variety of grain pulps, fruit pulps, starch pastes, ointments, mother liquors, potato mash, wine, and distiller's grains.
Advantages Compared to Other Pumps
1. Compared to centrifugal pumps, single screw pumps do not require valves, and their flow rate is a stable, linear flow.
2. Compared to pneumatic diaphragm pumps, single screw pumps can transport a variety of mixed media containing impurities such as gases, solid particles, or fibers, as well as various corrosive substances.
3. Compared to gear pumps, single screw pumps can transport highly viscous materials.
4. Unlike plunger pumps, diaphragm pumps, and gear pumps, screw pumps can be used for filling and metering pharmaceuticals.
Due to their structure and operating characteristics, screw pumps offer the following advantages over piston pumps, centrifugal pumps, vane pumps, and gear pumps:
Screw pumps can transport media with high solids content, with uniform flow and stable pressure, which is more pronounced at low speeds. The flow rate is proportional to the screw pump's speed, resulting in excellent variable controllability.
One pump can be used for multiple purposes, transporting media of varying viscosities.
The screw pump can be installed at any angle. It is suitable for transporting sensitive items and items susceptible to damage from centrifugal forces.
Screw pumps are compact, lightweight, low-noise, simple in structure, and easy to maintain.

Small and Micro Screw Pumps are specialized hygienic pumps designed for the precise transfer of viscous, shear-sensitive, and delicate fluids in the pharmaceutical, food, and Cosmetic Industries. Constructed from 316L stainless steel or food-grade materials, these pumps meet strict sanitary standards, ensuring contamination-free handling of high-value fluids such as liquid pharmaceuticals, creams, syrups, sauces, gels, and essential oils.
The pumps utilize single-screw or micro-screw designs, delivering gentle, pulsation-free, and accurate flow, making them ideal for small batch production, laboratory applications, pilot plants, and precise dosing processes. Compact and lightweight, they integrate easily into automated production lines, filling machines, and sampling systems, enabling precision control and consistent output.
Available in small, micro, and miniature sizes, these screw pumps are engineered for high reliability, easy maintenance, and hygienic compliance. The seal-less or mechanical seal configurations prevent leakage, reduce downtime, and maintain product integrity even with viscous or shear-sensitive fluids.
