Description

The High-pressure simmering 40x80x7.5 BAHD FPM is a specialist shaft seal used in hydraulic engines. These engines are a key component of hydrokinetic drives, which are widely used in various industries. The simmering is characterized by an open metal insert on the front side. This design creates a stable contact surface that protects the seal from deformation under pressure. As a result, the simmering is resistant to high pressure and can operate under challenging conditions. The product is made of NBR, or nitrile rubber. This material is known for its durability and resistance to various external factors. The 40x80x7.5 BAHD FPM simmering can operate at a maximum working pressure of 150 bars. The average working pressure is 100 bars, and the maximum linear speed is 2 m/s. It's worth noting that simmerings marked with the symbols BAHD, BAHDSN, and BAKHDSN are interchangeable. This means they can be used interchangeably in the same applications. In conclusion, the high-pressure simmering 40x80x7.5 BAHD FPM is a specialist shaft seal that is essential in hydraulic engines. Its robust construction and high resistance to pressure make it a product that will perform well under the most demanding conditions.

Material

FPM / FKM (fluoroelastomer, Viton®)

  • Operating temperature-20 °C to +200 °C

Good for high temperature, all fuels and oils, ozone and sunlight. Not for brake fluid, acetone-type solvents, ammonia, hot steam or severe cold.

Chemical resistance
Can be usedDo not use
High temperatures, continuously up to +200 °CAcetone, MEK, dioxane, ethyl acetate and similar solvents
Mineral and synthetic oils, incl. engine oil and oils with aggressive additivesBrake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells
Benzene, toluene, xylene, trichloroethylene (aromatic and chlorinated solvents)Ammonia, amines and alkaline liquids: the rubber breaks down
All fuels: petrol also with bioethanol (E10, E85), diesel, biodiesel, aviation petrolSteam and hot water above +120 to +130 °C
Fire-resistant hydraulic fluid HFD-R (phosphate esters)Formic acid and strong acetic acid (low-molecular organic acids)
Ozone, UV and sunlight (hardly any ageing)Severe cold below -20 °C with standard FPM: it hardens and leaks
Deep vacuum (very little outgassing)Hot fluorine gas and hydrofluoric acid (HF)

Safety: if the seal is heated above +300 °C (fire, gas torch), FPM releases toxic hydrogen fluoride. Do not touch the burnt residue with bare hands: it forms hydrofluoric acid and causes chemical burns.
