China Origin Polymer Melt Pump, High Precision Stabilized Gear Pump for Synthetic Fiber Twin Screw Extrusion

If you run synthetic fiber compounding and spinning lines with twin screw extruders, consistent melt metering and stable pressure directly decide fiber uniformity, yarn strength and final yield. Our China-origin polymer melt gear pump is engineered exactly for this demanding scenario, delivering high-precision, low-pulsation melt conveying and pressurization for PET, PA, PP, PLA and other synthetic fiber extrusion processes.

As a positive displacement gear metering pump, this polymer melt pump separates the homogenizing task from the metering task of your twin screw extruder. The twin screw takes charge of melting, mixing and modification, while the melt gear pump precisely controls melt flow, stabilizes die pressure and offsets inherent pressure fluctuations from the extruder. This combination greatly narrows melt flow deviation, reduces filament diameter variation and cuts scrap rate for staple fiber, filament and functional synthetic fiber production.

Core Features for Synthetic Fiber Twin Screw Extrusion

High metering precision & stable output

Fine-ground gear pair and optimized clearance design guarantee linear flow output against rotating speed. Flow fluctuation is controlled within a tiny range, avoiding thin-thick inconsistency of synthetic fibers. It supports variable frequency speed adjustment to match different line throughput requirements flexibly.

High temperature & high viscosity resistance

Adopted premium hot-work die steel for gear and pump body, with hardening and anti-corrosion treatment. It works reliably under continuous high temperature up to 350–400°C, suitable for high-viscosity polymer melt in fiber modification, color masterbatch compounding and bio-based fiber twin-screw extrusion lines.

Stable pressure & low pulsation**

It builds steady back pressure for the die head and suppresses pressure spikes from twin screw rotation. With this pump installed, your extruder can run under lower pressure, which lessens shear heat, shortens polymer residence time and prevents thermal degradation of sensitive fiber materials.

Solid China manufacturing & flexible customization

Made in China by specialized melt pump factory, compatible with mainstream twin screw extruder brands. We support custom displacement, flange connection, heating channel layout and sealing structure according to your synthetic fiber formula and line layout. CE certification available for global.

Energy saving & extended service life**

After adding the stabilized gear melt pump, the load of twin screw extruder drops obviously. The whole extrusion system consumes less power, and screw and barrel wear slows down, helping you lower long-term operation cost.

Typical Applications

PET, PA6, PA66 polyester and polyamide synthetic fiber compounding & spinning

PP spunbond, meltblown nonwoven fiber twin-screw modification

PLA, PBAT biodegradable fiber extrusion

Carbon fiber precursor, aramid and other high-performance fiber metering

Color masterbatch, functional additive masterbatch twin screw pelletizing before spinning

Why Pair This Stabilized Gear Melt Pump with Twin Screw Extruder for Synthetic Fiber?

Many synthetic fiber producers only rely on twin screw itself to control melt delivery. Twin screws excel at mixing, but cannot maintain ultra-stable flow under changing viscosity or feed variation. The melt gear pump acts as an independent metering booster: it locks the melt output, stabilizes spinning pressure and creates repeatable production conditions batch after batch. This is critical when you need consistent yarn tenacity, even dyeing performance and stable spinning continuity.

FAQ

Can this melt pump match my existing twin screw extruder?

Yes. We confirm working temperature, melt viscosity, required output and connection size to offer matched pump models and adapter flanges.

Does it work for high pressure spinning process?

This stabilized gear pump supports high-pressure build-up, widely used before spinning die for synthetic fiber production with strict pressure requirements.
