Gear pumps are suitable for conveying a variety of lubricated liquids. There are many types of gear pumps. How do you choose the right model?
1. In selecting the gear pump model for the customer, it is necessary to select the appropriate gear pump according to the customer's needs.
2. Be sure to know what type of gear pump requires media, viscosity, and flow.
3. The gear pump is suitable for working at what temperature.
4. The medium conveyed by the gear pump has no lubricity and contains particles.
5. When the gear pump is working under high temperature, the company must indicate when ordering the customer.
6. What is the ph value applicable to the medium, and whether the corrosiveness of the medium of the gear pump under normal operation may change with temperature.
7. What is the pressure used by the gear pump, how many elbows are in the pipeline, how long the actual pipeline is, and how high the highest point is.
8. Does the gear pump have a positive or negative phenomenon when it is working? If reverse pumping is used in the work, the company should indicate it when ordering. The gear pump cannot be reversed when it is equipped with a mechanical seal, and the conventional gear pump reversely causes the gears inside the gear pump to fall off.
