Compressors and Pumps

Pumps and compressors are used in any sector, for example:

  • Oil and gas;
  • Chemical processing;
  • Water and waste treatment;
  • Medicine;
  • Paper production;
  • Mining.

Often these machines run 24/7, so the main needs are as following:

  • Long duration;
  • No lubrication;
  • Friction reduction;
  • Energy saving;
  • Low heat generation.
Type of Applied Loads

Type of Applied Loads

There are several types used in this sector: starting from deep groove ball bearings (DGBB), passing through angular contact bearings with one row of balls (ACBB), up to tapered roller bearings (TRB). It is possible to have customized solutions (acting on: quality of steel, number and size of balls, number and size of rollers).

Accuracy of the work performed

Accuracy of the work performed

The choice of the Radial Clearance is crucial, starting from the Standard ones (Normal, C2 and C3) and also Customized Range. Furthermore, it is important to ensure the absence of vibrations produced.

Protection from external contaminants

Protection from external contaminants

Another aspect to take care of is to prevent the intrusion of external bodies or water / chemical agents, which can lead to premature wear of the pump / compressor, therefore solutions with improved sealing labyrinth are available in order to create the most adverse way to any external agent.

Key requirements

Key requirements

1. Super pure 100Cr6 steel to increase bearing life;
2. Fine grinding to reduce surface roughness;
3. Super-finish to reduce surface roughness;
4. Improved raceway design;
5. G10 grade balls to reduce friction;
6. Special design of the seals, with one or more lips;
7. Ultrasonic cleaning combined with demagnetization treatment;
8. Lubricating greases to reduce friction and optimize sliding;
9. 100% control of noise and vibrations, along the production process;

Our challenges

Our challenges
