Precision Spinning Metering Pump for High Viscosity Fluid
This series of 1-inlet 5-outlet precision spinning metering gear pumps are high-precision melt metering and conveying equipment specially developed for filament spinning processes such as polyester and nylon. With a precision gear meshing structure, it realizes uniform flow distribution from a single inlet to 5 outlets, providing stable and accurate conveying for spinning melt or oil agent. It is a core component ensuring the uniformity of spinning finished products and production continuity, and is widely suitable for high-viscosity fluid metering scenarios in chemical fiber, chemical, food, pharmaceutical and other industries.

Extended Applications: Precision oil metering, high-viscosity fluid booster conveying, special material extrusion supporting, etc.
Product Advantages
Multi-channel Precision Distribution: Uniform flow at 5 outlets with minimal error, eliminating uneven spinning thickness and broken filaments.
High Pressure and Temperature Resistance: Maximum outlet pressure of 40MPa, temperature resistance up to 320ºC, suitable for high-temperature and high-pressure spinning working conditions.
Strong High-viscosity Adaptability: Can transport high-viscosity spinning melt up to 4000POISE, meeting the stringent requirements of the chemical fiber industry.
Complete Specifications: Full displacement coverage from 1.2 to 5.0cc/rev, accurately matching spinning lines with different production capacities and processes.
Standardized Installation: Unified mounting flange and screw specifications for all models, facilitating line transformation and maintenance.
Structural Interface Features
Installation Interface Specifications
Mounting Flange: Φ120mm standard spinning machine flange with 2×Φ12.5 + 3×Φ13 mounting holes
Shaft End Specification: Φ20mm standard drive shaft, compatible with universal spinning machine power interfaces
Inlet/Outlet Ports: 1×Φ20mm inlet, 5×Φ7mm outlets, meeting the oiling/metering needs of multiple filaments simultaneously
Dimension Explanation
Dimension A: Main body length of the pump, varies with displacement (larger displacement = longer body length)
Dimension B: Total length of the whole machine including shaft end (A + shaft extension length)
The flange diameter of Φ120mm is fixed for all models, only the length varies with displacement.
