guangzhou moni electromechanical equipment co

The company, headquartered in Stamford, North Carolina, USA, has been engaged in the design and manufacturing of precision gear pumps since 2001. Products include gear pumps, metering pumps and rotor pumps. Services include pump restoration and transformation. Product application areas include chemical fiber, injection, extrusion and additive filling. As an innovator in gear pump application technology over the years, it has been recognized by many industries and users.
The company developed the original pump (polymer extrusion pump) design for extruding film, sheet, and profiles, all based on polyester and nylon polymers. Since then the company has supplied virtually every pump produced from polymers in the plastics industry. This development process also included many improvements to the series of pumps, giving them even better performance.
The unique positive displacement design of the pump series allows it to deliver polymers accurately and stably, and is not affected by changes in conditions such as pressure, temperature, and viscosity. Series pumps provide pressure between the extruder and the die and can be matched to the extruder parameters to provide a uniform melt as output increases and tight tolerances are required.
Today the company's series of pumps have become widely used elements in the production of polymers in the plastics industry. The company's products can be found wherever precise, pulsation-free and repeatable metering of fluids is required
For many years , In the production of the plastics industry, many polymer production equipment have used gear pumps to assist extrusion to solve various key problems. The gear pump cooperates with the extruder to optimize the entire extrusion process.
The extruder melts the polymer and makes it uniform. The pump then provides the required pressure, easing the work of the extruder, thus reducing the shear heat and required torque, and eliminating fluctuations, all of which optimize extruder performance and offers the following advantages: Improved dimensional stability effectively isolates the die from fluctuations from upstream.
Control the melt quality and adjust the extruder back pressure to reduce the residence time, stabilize the plasticizing effect, and lower the melt temperature.
Increased throughput provides very high efficiency regardless of the required pressure build
Reduced raw material usage provides small dimensional changes in the final product
Eliminates fluctuations and screw shocks effectively solves problems caused by melt Problems caused by density or extruder parameters
Enhanced extruder flexibility allows changes to the workpiece, such as higher regrind amounts, temperature and pressure, etc.
The crown tooth root design reduces the internal shear force on the pump
Reasonable closed-loop control of operation and operation, providing a simple operation interface
Extending the service life of the extruder reduces the working intensity of the extruder , such as pressure and torque.
Low operating costs provide a more efficient conveying method, avoid raw material waste, and increase the output per pound of extrudate.

Advantages
The polymer extrusion pump adopts a unique positive displacement design, which can provide stable performance under changing extrusion conditions such as pressure, temperature and viscosity. , accurate polymer delivery. Since the pressure is built up between the extruder and the mold, when the extruder parameters are properly configured, a uniform molten mass can be delivered at higher throughput while meeting tighter tolerance requirements.
The pump is available in a variety of capacities and models. It can provide accurate, stable and reliable fluid metering and is suitable for almost all polymers used in the plastics industry, including chemical fiber polyester, polypropylene, nylon, acrylic fiber, cellulose , spandex and many specialty fibers.
