What is a Gear Metering Pump?
A gear metering pump is a type of positive displacement pump that relies on a pair of gearsone driving and one driven, encased in a compact chamber. The liquid is drawn in through the inlet as the driving gear rotates and transported out through the outlet as the driven gear rotates. This mechanical design ensures that fluid is released at a continuous rate proportional to the rotation rate. The reliability and precision of gear metering pumps have made them popular among critical industrial processes.
Internal Structure and Working Mechanism
- Drive Gear and Driven Gear
- The drive gear is connected to a motor or manual drive mechanism.
The driven gear is meshed with the drive gear and rotates due to mechanical contact.
Fluid Entry and Exit Ports
- Inlet port: The fluid enters the pump through the inlet port.
Outlet port: The fluid is discharged through the outlet port.
Tight Tolerance Gear Fit

Aug 8th , a delegation from Trustech, a leading enterprise in the hollow fiber membrane spinning field, visited Suzhou National Laboratory for technical exchanges. As the only manufacturer in China that covers the full industry chain of hollow fiber membrane spinneret plates, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment for the fields of environmental water purification, gas separation membranes, and medical hemodialysis membranes, Trustech focused this visit on frontier technologies in membrane materials, exploring in depth such directions as “equipment manufacturing + fundamental research,” and jointly seeking new paths for breakthroughs in cutting-edge materials technologies and their industrial transformation. As a China leading membrane spinning machine and hollow fiber membrane spinneret manufacture, Trustech is expanding its collaboration with top national research platforms.
In NIPS and TIPS ultrafiltration hollow fiber manufacturing, the spinneret is not just a “die with holes.” A membrane spinneret must co-extrude polymer dope and bore fluid with strict concentricity, maintain a stable flow field through multi-hole distribution, and preserve a controlled thermal–mass transfer history to form a uniform lumen and selective skin. Regular textile spinnerets, by contrast, are optimized to produce solid filaments with comparatively broader tolerances and simpler flow control. Understanding these differences prevents misapplication and protects yield, uniformity, and membrane performance.
Thermally induced phase separation (TIPS) turns a hot, homogeneous polymer–diluent solution into a finely tuned porous hollow fiber as it cools and crystallizes.
TRUSTECH is accelerating the industrialization of high performance hollow fibers used across water treatment, healthcare, and chemical applications.
From June 9 to 11, 2026, the 18th Shanghai International Water Exhibition (WATERTECH CHINA 2026) grandly opened at the National Exhibition and Convention Center (Shanghai, Hongqiao). As the world’s largest and most influential annual event in the water treatment industry, this year’s exhibition brought together more than 2,500 domestic and overseas brands and attracted about 100,000 professional visitors from China and abroad. It comprehensively covered core fields such as membranes and water treatment, environmental water treatment, and smart water services. More than 80 high-level forums held during the same period gathered over a thousand industry experts to deeply decode cutting-edge trends along the global water treatment industry chain.
Hollow fiber ultrafiltration performance is inseparable from spinneret design and the phase separation pathway that turns a polymer solution or melt into a stable, selective, and scalable membrane.
In the field of hollow fiber membrane spinneret heads, Trustech has received another piece of good news: its independently developed "Modular Multi Orifice Hollow Fiber Membrane Spinneret Head" has been granted a national invention patent (Authorization Announcement No. CN104894663B). With its digitized, modular, and flexible design innovations, this patented technology injects strong momentum into the industry's development.
A new fifth-generation “FCT” spinneret plate architecture introduces modularity, higher precision, easier maintenance, and longer service life—benefits that directly translate into tighter fiber geometry control, improved uptime, and more consistent membrane performance on both NIPS and TIPS lines.
Hollow fiber membranes have really been making waves in the filtration world lately. Companies like Memstar and Koch Membrane Systems are definitely leading the charge with this tech. But here’s the thing—how well these membranes work really depends a lot on the manufacturing process used during spinning. So, it’s a good question: what production methods are actually best suited for making hollow fiber membranes?
In hollow fiber ultrafiltration, the spinneret plate sets the hydraulic and geometric starting point for fiber formation. For both NIPS (Non-Solvent Induced Phase Separation) and TIPS (Thermally Induced Phase Separation), its internal channels, dimensional fits, outlet geometry, and thermal behavior jointly determine fiber uniformity, wall symmetry, lumen hydraulics, and downstream phase-separation stability. This blog distills the core design factors and the system logic behind them, with notes on avoiding common pitfalls. Trustech integrates these principles into practical designs that balance precision with maintainability on industrial lines.
