The MP-R series of bottom pumps is the first gear pump used in the entire polymer process...
It is used in high temperature (≤350°C), medium and high pressure (≤15MPa), and high viscosity (≤20,000Pa·s).
Low pressure flow ripple and near-linear output
Good self-priming performance, can be applied to the working condition of vacuum inlet (-0.05~-0.09MPa)
The structure is precise, the precision is high, and the service life is long
The bottom pump is the first gear pump used in the whole polymer process, the multi-component material is formed by chemical reaction in the reaction kettle, under the action of the weight of the material itself and the external air pressure, the polymer enters the gear pump installed at the bottom of the reaction kettle, and the bottom pump must be able to form a large vacuum environment when working, so as to pull the material in. The product category code of kettle bottom pump is R, there are three series of RS, RM, RL, using large suction inlet flange design, the inlet and outlet runner adopts fine polishing process, the internal structure is compact, the sealing is reliable, and the high negative pressure environment is formed during operation, and the material is conveyed smoothly and uniformly. It can convey polymers, asphalt, adhesives, chemicals, food, grease, fuel, oil, paint, lubricants and other high-viscosity materials that do not contain particulate impurities.
They are: Max-Roth (Louis) low-pressure kettle bottom pump, Max-Roth (Harbin) autoclave bottom pump.

The melt pump can be said to be a relatively large-scale mechanical equipment, so the general purchase price is relatively expensive. Therefore, users are very cautious when purchasing and want to choose a well-known manufacturer and good brand to purchase. Today's machinery manufacturing market is a mixed bag. There are many names for the same equipment, and the manufacturer's brands are also different. Users are also confused about which one is......
Melt pumps have the advantages of compact structure, simple manufacturing process, low cost, and insensitivity to oil contamination, and are widely used. However, due to defects or improper maintenance in manufacturing, assembly, operation, and maintenance, the pump will often be damaged prematurely or even scrapped, causing the actual service life of the pump to fail to meet the design requirements. The main influencing factors are analyzed as f......
The melt metering pump is mainly installed at the outlet of the extruder for metering and pressurizing various melts. The advantages of the melt metering pump are safe and reliable operation, stable performance, long service life and low operating costs. The extruder melt metering pump is a positive displacement pump, and different materials can be selected to meet the needs of transporting different melts; the model size of the melt metering pum......
Theoretical displacement of melt pumpThe volume of melt discharged per revolution is called the theoretical displacement of the melt pump, or pump displacement, and its unit is cc/r or cm³/r. The specifications of melt pumps are generally expressed in terms of displacement.Theoretical flow rate of melt pumpIgnoring the influence of leakage, the unit calculated based on the geometric dimensions of the melt pump, the melt flowing through the melt p......
