How to prevent damage to a contamined hydraulic system?
Several measuring devices can prevent damage to a hydraulic system:
- a filter maintenance indicator
- a water content measuring device
- a particle counter
See our article on HYDRAULIC CIRCUIT CONTAMINATIONS to learn more.
How to avoid particle contamination of a hydraulic system when filling oil?
For manual filling, make sure the oil cap is clean and that you use a dry funnel (free of water or other fluids) and free of dust or particles.The use of a filter pump to transfer oil from the gallon to the tank is a useful method of preventing contamination and ensuring the protection of the hydraulic system.

How to identific hydraulic contamination?
Tests are used to determine whether or not contaminants are present. This is most often done by analyzing the viscosity, water content, or solid content.
See our article onHYDRAULIC CIRCUIT CONTAMINATIONS to learn more.
How to clean a contaminated hydraulic system?
To clean a contaminated hydraulic system, there are equipments which allow a depollution of the fluid in a hydraulic circuit.
- Mobile filtration units can be connected to the circuit, allowing the fluid in the circuit to be depolluted
- The installation of fluid purifiers is a more complete system to clean up a fluid contaminated by particles, water or gases.
- In some major cases, a complete emptying followed by a cleaning is necessary.

What are the different types of hydraulic fittings?
There is a multitude of hydraulic fittings. They are differentiated according to several criteria:
- Male or female connections,
- Straight or angled fittings,
- Rigid or swivel fittings.
Hydraulic fittings are available in many sizes and depending on your needs, fittings should be selected according to the type of hydraulic hose (braided, spiral, high pressure, thermoplastic or other). For more information, see the TYPES OF FITTINGS AVAILABLE from HP Hydraulics.
What are Bosch Rexroth products?

What is the difference between an open and a closed hydraulic system?
An open system is one where the fluid flows from the pump through the valves and back to the tank. This means that the pump provides a continuous flow to the hydraulic system. In addition, an open circuit is a one-way circuit, which means that the fluid can only flow in one direction.
On the other hand, in a closed-loop hydraulic system, the fluid from the piston pump flows directly to a motor and back to the pump without passing through the reservoir. The special feature of this type of system is its bi-directional operation.
For more explanations, see our ARTICLE ON THE DIFFERENCES BETWEEN AN OPEN AND CLOSED HYDRAULIC SYSTEM.
What is a printed circuit?
A printed circuit, or Printed Circuit Board (PCB), is a plate which ensures the connection of a set of electronic components and is used in many everyday electronic devices:
- Industrial equipment
- Medical environment
- Aeronautical environment
- Automobiles
- Electronic devices
- Household appliances
- Lighting

What is a high-precision, portable 3D scanner (short-range)?
This type of scanner is a device that can be taken almost anywhere to create a highly accurate 3D scan of a part. The device emits a light source—projecting laser crosses onto the object being scanned—which enables the creation of a mesh that precisely represents the object’s surfaces. It can be used to scan parts of various sizes—from very small to very large—whenever high precision is required. This 3D scanner can be used to accurately replicate parts that are difficult to measure, or to inspect objects that must meet specific precision standards.

What is a long-range laser (or environmental) 3D scanner?
This type of scanner is considered “long-range” because it enables large-scale scanning. The device operates by emitting laser pulses, which generate a point cloud with each scan. By combining all these point clouds, the volume of the environment can be reconstructed without any physical contact. This type of scanner is used for very large objects, as well as for entire environments—such as a room, a section of a factory, an outdoor courtyard, etc.
