What are the advantages of Nord pump and gear pump

Release time:

2024-07

1. Ultra-wide viscosity range and impurity passing capacity have obvious advantages in places with high viscosity and high impurity content. There is no need to install a filter screen, and the flow and pressure are stable without fluctuation. 2. The sliding ring mechanical seal is used to automatically compensate for wear and the intermediate isolation cavity is designed, which is safe and reliable. Optional leak alarm device.

NORD pump

1. Ultra-wide viscosity range and impurity passing capacity have obvious advantages in places with high viscosity and high impurity content. There is no need to install a filter screen, and the flow and pressure are stable without fluctuation.

2. The sliding ring mechanical seal is used to automatically compensate for wear and the intermediate isolation cavity is designed, which is safe and reliable. Optional leak alarm device.

3. Low speed, optimized design of three-wing spiral rotor, basically pulseless operation, extremely low noise and failure rate, and the service life under the same working conditions is more than 3 times that of gear pump.
4. It is not affected by the outlet pressure, medium viscosity and internal damage, and the current is stable. Under the premise of the same parameters, the energy consumption is more than 1/3 of the gear pump.

5, low failure rate, daily maintenance costs are very low. The daily maintenance cost of each pump is about 100 yuan per year. Only need to replace gear oil, seal cavity oil, etc.

Real online speed maintenance, no need to disassemble and move any equipment, non-professionals only need about 60 minutes to complete the replacement of wearing parts.


gear pump

1. It is greatly affected by medium viscosity and impurities, especially in summer and winter, there will be no bite and insufficient flow during operation. If there are impurities, need to install filter to protect the main part of the pump gear.

2. The gear pump is easy to leak in the stuffing box during operation, and there is no leakage isolation measure. It is also not possible to install a leak alarm device.

3. The design of the gear-type wing has large pulsation during operation, and the pump has large vibration, high noise, prone to failure, high maintenance rate and short life.

4, vulnerable to external internal factors, such as high pressure, viscosity is too large, poor shaft seal assembly, shaft and bearing wear caused by current instability, huge energy consumption.

5, gear pump failure rate and daily maintenance costs are high. The daily maintenance cost of a pump is as low as 500 yuan. The larger the model, the higher the cost.

6. If the gear pump fails to replace the overcurrent parts, the pump must be disassembled from the system for maintenance. It is more complicated and requires professional personnel to complete the repair.
