rubber, including radial and shaft seal rings and O-rings. Not suitable for fire-resistant hydraulic fluids from the HFD group. Permissible temperature range -30°C to 100°C. Elastomers

circuits or in the control oil supply of pilot stages. Protective filters do not clean the pressure fluid and therefore their filter unit (β-value) should be more coarse than cleaning filters.

motor in series connection, power-controlled pump, compressed air cylinder (connection behaviour of fluid drives). Opposite: position dependent locking , where it is possible to have an output variable which

The gear pump is a machine for conveying fluids in accordance with the Positive displacement principle . In principle it consists of three components: a housing with inlet and outlet and two gear wheels

reciprocal of the Kompressionsmodul K. The value of K can be assumed to be 1400 MPa for a hydraulic fluid. Calculate the volume reduction on pressure increase directly and easily in our hydraulic calculator

point . The pour point cannot be used to assess the characteristics at low temperatures of pressure fluids based on vegetable oil. This is because time is a factor here, as well as temperature.

Overload protection helps secure the system against excessive operating pressures. In fluid technology, the overload protection is provided by the working method of the pressure-limiting valve, which starts

(depending on the shape of the cross section), a laminar flow will apply. The individual elements of the fluid only move in the direction of the flow. As a result of viscosity, the local velocity across the cross

Characterises the Viscosity/temperature characteristic of a fluid. The smaller the change in viscosity with respect to temperature, the higher the VI (CETOP RP 100). The VI is mathematically calculated

Reflects the ability of a hydraulic fluid to reduce mechanical wear on moving parts of a hydraulic system which it comes into contact with. To improve the wear protection capacity, wear protection agents
