We are a Chinese manufacturer specialising in rotor pump filling technology — the pump is the metering element. We built China's first servo rotor pump filling machine in 2018, and we do not make piston fillers.

Servo-driven, metering-grade rotor pump. ±0.5% accuracy for high-viscosity pastes, sauces with particles and large-particle products. GTX series, 5–300,000 ml.
For thin liquids such as milk, beverages and edible oil — stable, high-speed volumetric filling.
For products that need a different discharge principle — assessed against your product sample.
Filling + bagging, capping, labelling, coding and conveying, engineered to your container and line speed. OEM / private label supported.
Our metering-grade pump supplied as a component (LX-9 / LX-18 / LX-36 / LX-60) — for OEMs building their own filling equipment.
CIP-capable rotor pump production validated in dairy projects (2020) — suitable for dairy, beverage and aseptic-adjacent lines.
A specialist manufacturer, not a trading company — you deal with the people who design and build the machine.
We focus on metering-grade rotor pumps for filling. That is a different standard and design intent from the conveying-grade rotor pumps common in the industry. We do not manufacture piston pumps.
±0.5% fill accuracy, error ≤1 g — reducing product give-away and material waste on every single container, shift after shift.
40,000+ units delivered and 10,000+ fluid application profiles accumulated since entering the rotor pump field, with customers including major dairy and food groups in China.
Pump head (three-lobe, single-lobe, waist, twin-lobe, five-lobe) × hopper (standard, agitated, heated, square-mouth) × filling valve (blow-spray, full-immersion, sauce cut-off) — configured to your product.
National High-Tech Enterprise (2024), National Sci-Tech SME (2025), Provincial Innovative SME (2024), 32 patents, licensed for import and export.
Export packing, English documentation, remote commissioning guidance and spare parts supply for international customers.
Our filling equipment is in production at leading Chinese dairy, food-service and condiment groups — including Mengniu, Yili, Junlebao, Haidilao and Lee Kum Kee — and covers more than 70% of domestic dairy plants.

Milk, yoghurt, juice and syrups — CIP-capable, high-accuracy filling on fast lines.
Chilli sauce, bean paste, jam, dressings and fillings with particles — the rotor pump's core advantage.
Creams, gels, adhesives and coatings — 304/316L wetted parts, configurable discharge.
A filling machine that uses a servo-driven rotor pump as the metering element instead of a piston. It achieves ±0.5% accuracy (error ≤1 g) and handles 50–300,000 cSt products, including pastes with large particles.
Yes. With no piston or narrow valve seat to block or crush solids, the rotor pump fills pastes and particle-containing products reliably.
5 ml to 300,000 ml per fill across GTX-900, GTX-1800, GTX-3000/3600 and GTX-6000. See the specification table.
Yes — filling combined with bagging, capping, labelling and coding, engineered around your container and line speed. OEM and private label supported.
