Spinning metering pump | Spinning pump | Pulse-free metering pump | Precision metering pump | Chemical fiber pump

In 2007, the synthetic fiber industry required the design of a gear metering pump with high precision, no pulsation, and good online performance to ensure better quality control. The same problem exists in the chemical industry. Currently used diaphragms, peristaltic pumps, precision gear pumps, piston pumps, plunger pumps and screw pumps all have problems such as pulsation, inaccurate metering, multiple seals and slippage. These pumps also require regular calibration, expensive repairs and lengthy downtime.
The above problems were solved and a high-precision and simple-structure rotating external gear pump was designed. Current manufacturing technology ensures positive and negative errors, thereby minimizing internal gaps to ensure accurate and precise measurement. This pump has only three moving parts (two metering gears and a drive shaft). Its simple design provides a long service life and easy maintenance.
For many years, chemical engineers have relied on the high-precision fluid metering provided by Method, where can you find the gear metering pump.
Advantages of spinning metering pump
Pulsation-free output, continuous operation, high precision, good repeatability, used for precision metering of industrial fluids. High-precision spinning metering pump Stable, reproducible fluids are guaranteed even under changing conditions of pressure, viscosity and temperature. High metering accuracy.
Minimum pulsation of the spinning metering pump. The unique design provides the ultimate pulsation-free fluid without the need for obstructions. Performance valves and movable coupling elements.
Spin Metering Pump Corrosion Resistance For most conventional chemical applications, series stainless steel has good wear and corrosion resistance properties.
Spin Metering Pump High Temperature Performance Operation Temperature reachability
Spinning metering pumps have only three moving parts to extend their service life. These parts are made of hardened steel with a hardness up to Assembled, replaceable sleeve bearings are standard parts.
The high volumetric efficiency of the spinning metering pump The increased volumetric efficiency is achieved by an optimal operating clearance and is guaranteed under pressure by an internally installed adjustment plug.
/> The structure of the spinning metering pump is precision ground and overlapping free parts are used for closing control of the operating gap.

Precision measurement
The gear metering pump has a unique internal structure and advanced processing technology. All pump parts are precision ground and their dimensional errors are controlled to ensure that the internal clearance value of the pump is minimized to improve volumetric efficiency and ensure output flow. accuracy, and reduces the impact of changes in external working conditions on its metering precision. Using the accuracy of the metering pump, various additives can be precisely metered and evenly injected into the corresponding chemical raw materials for final use. Manufacturing of products. This application has been widely used in fine chemical and general chemical industries such as medicine, detergents, papermaking, petrochemicals, rubber and plastics, paint making, polyurethane, etc. It is also used in tobacco, brewing, beverage, food and other industries. Measure various spices, vitamins, food colorings and other auxiliary materials to ensure product quality and control production costs.
Coating process
Compared with various other metering pumps (piston pumps, diaphragm pumps), gear metering pumps have the characteristics of pulsation-free output and are particularly suitable for coating processes. At present, gear metering pumps have been widely used to spray photosensitive emulsions in the production of photographic film, photo paper, printing plates and other products, as well as spray magnetic slurry in the production of tapes, disks, and cards, meeting the high-quality requirements of the coating process for these products. Require. At the same time, this property is also used in surface painting, such as in the automotive industry. The special gear metering pump can also have fast cleaning characteristics to meet the requirements for quick replacement of paint during the production process.
Measuring and conveying of high-viscosity materials
Working principle of gear pump
It is a closed gear space formed by a pair of intermeshing gears and the pump body, and the material is transferred from the inlet of the pump to The outlet of the pump, and through the meshing of the gears at the outlet, the enclosed space becomes smaller, so that the material is squeezed out of the pump body. Therefore, there is no one-way valve device in the gear pump. The characteristics of this structure make the gear pump most suitable for transporting metered high-viscosity fluids. It overcomes the pump efficiency problems caused by reciprocating pumps such as plungers and diaphragms due to adhesion and lax closing of the one-way valves when the material viscosity is high. The phenomenon of reducing, measuring inaccurately and even being unable to work. Gear metering pumps can be used in the production of hot melt adhesives, adhesives and polymer polymer products. In other industries, such as self-adhesive paper stickers, tapes, automobile windshield bonding, engine cylinder head seals, electronic components and It has also been widely used in the industrial production of rubber and plastic products.
