What are your suggestions for finding a replacement gear pump for the original imported plug pump? Let’s discuss!
Thread Content
The company's imported cock pump, model TRA20 0450, has aged and cannot meet the needs of the work. The company does not want to buy imported pumps and wants to replace it with a gear pump. I have been looking for a long time but haven't found a suitable one. I have also looked for a twin-screw pump, but the design institute said that it must be a conventional pump to avoid future maintenance troubles. Now I have selected a plunger pump, but the company wants to use a gear pump. The following are the required process parameters. I hope you can discuss it! The inlet pressure is 0.1mpa, the pressure difference between the inlet and outlet is 5mpa, the flow rate is 1.5m3/h, and the transport medium is polymer slurry (containing a small amount of hydrochloric acid, PH value 2.5-4.5, a large amount of DMAc solvent, which will dissolve some rubber and plastics, and the slurry also contains a small amount of calcium hydroxide particles). The medium temperature is 40-55 degrees, the medium viscosity is 15000-40000cp, and the main purpose is to transport the slurry and filter it through a plate and frame filter.

In order to control changes in viscosity, you can also choose a jacket, etc. However, you should pay attention to the good calcium hydroxide particles contained and choose a hard-to-hard mechanical seal. A small amount of pellets is no problem. If there are too many particles, the gear pump is not suitable. Since the medium contains hydrochloric acid, it will dissolve some rubber and plastic, and the slurry also contains a small amount of calcium hydroxide particles. You may need to pay attention to the material selection of the pump. The plunger pump is not suitable for conveying high-viscosity materials, and the cost will be very high. Problem-prone. It is recommended that you use the American Viking gear pump. Personal opinion.
