Application of MonyPumps Gear Metering Pumps in Hollow Fiber Ultrafiltration Membrane Production

There are many types of hollow fiber membranes, primarily polymerized from high molecular materials such as: polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), polysulfone (PS), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polyethylene glycol, N-methylpyrrolidone (NMP), etc. These raw materials are relatively expensive, and even small, long-term wastage can gradually increase product costs.

The uniformity of the hollow fiber membrane pores is a critical factor in membrane filament indicators, with requirements including: a smooth and glossy membrane surface, and consistent inner and outer diameters of the membrane wall thickness. This also depends on the membrane material and production process requirements.

Industrial Challenges

Fluctuations in the liquid level within the reaction kettle due to system pressure variations (gas source pressure) can affect the consistency of membrane wall thickness and the uniformity of the central pore diameter, potentially preventing the product from achieving the expected quality.

Currently, domestic membrane manufacturers opt for methods such as pressurizing the gas source inside the reaction kettle. Can you ensure that the amount of membrane solution is precisely what the process requires? Can you guarantee stable pressure? Is the repeatability good?

If so, MonyPumps gear metering pumps can help solve this problem. MonyPumps gear metering pumps are high-precision, pulsation-free, and offer excellent repeatability.

MonyPumps Fluid Solutions

The MonyPumps precision metering pump series is made from high-grade stainless steel materials, offering corrosion and wear resistance. Its inherent precision structure ensures high efficiency and high-precision fluid output even under changing conditions (such as pressure, temperature, etc.), meeting production process requirements. The internal structural design, combined with proprietary internal features, ultimately guarantees high precision, pulsation-free fluid output with excellent repeatability under various process conditions.

MonyPumps gear metering pumps provide accurate metering without the need for expensive metering instruments or other flow control devices.

You can freely choose the pump model, pump material, sealing form, and sealing material, among other options.

You can opt for a metering system with MonyPumps gear metering pumps paired with servo drives, or use MonyPumps gear metering pumps with standard geared motors, tailored to user process requirements.
