Filling machines and filling lines

Four product lines plus the metering pump itself, covering pure liquids, pastes, products with particles and large-particle solids — from 50 cSt to 300,000 cSt.

Technology note: our flagship is the metering-grade rotor pump for filling — a different product standard and design intent from conveying-grade rotor pumps. Because the range also covers piston, gear and screw pump fillers, the recommendation follows your product rather than a single technology platform.

GTX series servo rotor pump filling machines Flagship

Servo-driven, metering-grade rotor pump as the filling element. We introduced China's first servo rotor pump filling machine in 2018.

Accuracy: ±0.5% fill accuracy (error ≤1 g) on pure liquids; measured accuracy ±1 g–±2 g on particle-containing or high-viscosity products — a substantial improvement over conventional pneumatic piston fillers.
Very wide viscosity range: from thin milk-like liquids to 300,000 cSt pastes such as bean paste.
Particle tolerant: no piston or narrow valve seat to block or crush solids.
Modular build: 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).
Machine formats: semi-automatic 4-head, automatic single-head and multi-head, 8-head automatic with independent servo per head, and twin-head fill-and-top-up models.

Piston pump filling machines Full range

Where piston filling remains the appropriate technology for the product or the budget, we also build piston pump filling machines — pneumatic or servo-driven according to the accuracy, speed and hygiene requirement. Typical use is low to medium viscosity liquids and semi-liquids where a simple, robust dosing principle is sufficient.

Pneumatic or servo-driven configuration according to the accuracy target.
Wetted materials and cleaning capability matched to the product standard.
Supplied stand-alone or integrated into a line with capping, labelling and coding.

Screw down-press filling machines Special products

For products that need a screw down-press discharge principle rather than a pump. Suitability is assessed against your product sample — please send a sample description or video with your enquiry.

Custom filling lines Turnkey

Filling machine combined with bagging, capping, labelling, coding and conveying equipment — engineered around your container, product and required line speed. Non-standard and OEM/private-label projects are supported.

Pump head, hopper and filling valve selected from the product's viscosity and particle content.
Automation level and number of heads matched to your output target.
Filling stations built for your container type and dimensions.
Line layout and utilities assessed from your site conditions.

LX series metering-grade rotor pumps Component

The pump at the heart of our filling technology, available as a component for OEMs and integrators. Models LX-9, LX-18, LX-36 and LX-60 correspond to different displacements and fill ranges. It moves the rotor pump from conveying into metering and filling — a different design intent from conveying-grade pumps.
