Danfoss piston pumps are designed for high pressure applications in industries such as agriculture, construction and material handling. The seals in Danfoss piston pumps play a vital role in maintaining the integrity of hydraulic systems and preventing leaks.

The seals in Danfoss piston pumps usually consist of a combination of O-rings and high-pressure seals. O-rings are usually made of rubber or elastomeric materials and are used to seal static parts such as pump casings and valve bodies. High pressure seals are usually made of materials such as polyurethane or PTFE and are used to seal dynamic parts such as plungers and pistons.

Features of the seals in Danfoss piston pumps include:

High Pressure Capability: The seal is designed to withstand the high pressures generated by the pump, typically up to 400bar.

Chemical Resistance: Seals are designed to resist the effects of hydraulic fluids and other chemicals commonly used in industrial applications.

Abrasion Resistance: High pressure seals in seals are designed to withstand wear from repeated cycles of the pump.

Temperature Resistance: Seals are designed to withstand high temperatures from hydraulic fluid and other environmental factors.

Low Friction: Seals are designed to minimize friction between moving parts, reducing wear and increasing pump efficiency.

Overall, the seals in Danfoss piston pumps are key components to ensure reliable and efficient pump operation in demanding industrial applications.

Additionally, the seals in Danfoss piston pumps are designed to provide a high level of sealing performance against leakage, which can lead to loss of hydraulic oil and reduced system performance. O-rings and high-pressure seals work together to maintain a tight seal around dynamic components, preventing hydraulic fluid leaks and contaminants from entering the system.

Seals in Danfoss piston pumps may also include backup rings or wipers to provide additional sealing protection and prevent damage to dynamic parts. Back-up rings are typically used to support high-pressure seals, while wipers are used to remove contamination from the plunger or piston surface.

In summary, the seals in Danfoss piston pumps are key components that provide high pressure capability, chemical resistance, wear resistance, temperature resistance, low friction and a high level of sealing performance. O-rings, high pressure seals, backup rings and wipers work together to ensure reliable and efficient hydraulic system operation in demanding industrial applications.

Danfoss piston pumps are available in a variety of sizes and configurations to suit a variety of application requirements. Depending on the model, the seals may be located in various places within the pump, such as the plunger, piston or valve body.

A common type of seal used in Danfoss piston pumps is the axial piston seal, which consists of a series of high pressure seals arranged in a circle around a plunger or piston. This type of seal provides a tight seal against the cylinder block, preventing hydraulic oil leakage and ensuring efficient pump operation.

Another type of seal used in Danfoss piston pumps is the radial seal, which consists of a high pressure seal located on the plunger or piston and seals against the cylinder in the radial direction. This type of seal is typically used in small piston pumps where space is limited.

To ensure proper functioning and long service life of the seals in Danfoss piston pumps, it is important to follow the manufacturer's recommended maintenance procedures. This may include periodic inspection and replacement of O-rings, high-pressure seals, backup rings and wipers, as well as monitoring hydraulic fluid levels and system pressure. With proper maintenance of the seals, this pump will provide years of reliable, efficient operation.
