Suction Filter Elements: These are installed in the suction lines of hydraulic pumps to protect the pump from contamination. They filter out large particles that can cause damage to the pump.
Spin-On Filter Elements: These are easy-to-replace filter elements that are used in low pressure or return line applications. They come in a self-contained housing which makes them easy to install and replace.
Stainless Steel Filter Elements: These are made from stainless steel mesh and are used in applications where high resistance to chemicals or high temperatures is required.
Eco Filter Elements: These are environmentally friendly filter elements that are designed for easy disposal. They have a metal-free construction which makes them fully incinerable.
Each type of STAUFF filter element is designed with a specific application in mind and offers unique advantages. They all share the common goal of providing high-quality filtration to protect hydraulic systems and extend their service life.
The working principle of STAUFF filter elements is based on the process of filtration, which is a mechanical or physical operation used to separate particles and contaminants from fluids. Here is a detailed explanation of how they work:
Fluid Entry: The hydraulic fluid containing contaminants enters the filter housing. This is usually directed through an inlet port.
Filtration Process: As the fluid passes through the filter element, the contaminants are captured and retained. The filtration process can be done through different mechanisms - direct interception, inertial impact, or diffusion.
Direct Interception: When the contaminant particle is larger than the gap between the filter fibers, it is directly intercepted and retained by the filter.
Inertial Impact: When the fluid changes direction abruptly, the inertia causes the larger particles to continue in a straight path and collide with the filter fibers, leading to their capture.
Diffusion: This mechanism applies to very small particles. They are bombarded by molecules in the fluid, causing them to deviate from their path and collide with the filter fibers.
Fluid Exit: The clean fluid then exits the filter through the outlet port and returns to the hydraulic system. The filter element has successfully removed the contaminants, providing clean, filtered fluid to the system.
Contaminant Retention: The contaminants captured by the filter element remain trapped until the filter is cleaned or replaced. Over time, as more and more contaminants are trapped, the filter element will become clogged and less efficient, indicating that it needs to be replaced.
Filter Replacement: Once the filter element is clogged, it can be easily replaced with a new one. In the case of spin-on filter elements, the entire filter (including the housing) is replaced, whereas for other types, only the element inside the housing is replaced.
By using this filtration process, STAUFF filter elements effectively remove contaminants from the hydraulic fluid, protecting the system components and extending their service life.
The STAUFF filter elements are designed to capture and retain particles and contaminants through a process called filtration. Here's a more detailed explanation:
Direct Interception: The filter element is composed of a dense network of fibrous materials. As the hydraulic fluid passes through this network, particles that are larger than the gaps between the fibers are directly intercepted and captured.
Inertial Impaction: As the fluid flows through the filter, it undergoes abrupt changes in direction. This causes the particles in the fluid to continue moving in their original direction due to their inertia. As a result, these particles impact the filter fibers and are captured.
Diffusion: This process is particularly effective for very small particles. These particles move randomly due to constant collisions with fluid molecules, causing them to deviate from their path and come into contact with the filter fibers. This random motion increases the chances of these particles colliding with the filter fibers and being captured.
Sieving: This is the most common mechanism for particle capture. Larger particles are unable to pass through the small openings in the filter material and are thus retained.
Adsorption: Some filter elements, especially those made from activated carbon or other adsorptive materials, can capture particles through adsorption. The particles adhere to the surface of the filter material and are thus removed from the fluid.
The particles and contaminants captured by the STAUFF filter elements remain trapped within the filter material until the filter is cleaned or replaced. Over time, as the filter captures more and more contaminants, it may become clogged and less effective at filtering the fluid. This is an indication that the filter element needs to be replaced. By capturing and retaining particles and contaminants, STAUFF filter elements help to protect the components of the hydraulic system and extend their service life.
The STAUFF filter element is a key component in maintaining the cleanliness of hydraulic systems. It is designed to remove contaminants from the hydraulic fluid, thereby protecting the system's components and ensuring its efficient operation. Here's a detailed breakdown of its composition and function:
Filter Media: This is the heart of the filter element. It is typically made from a fibrous material such as glass fiber, cellulose, or synthetic materials. The filter media is responsible for capturing and retaining contaminants as the hydraulic fluid passes through it. The choice of filter media depends on the type of contaminants expected and the desired level of filtration.
End Caps: These are located at both ends of the filter element. They provide structural support and ensure that the fluid passes through the filter media. The end caps are typically made from metal or plastic.
Support Core and Outer Wrap: The support core provides structural integrity to the filter element, preventing it from collapsing under the pressure of the fluid flow. The outer wrap protects the filter media from damage and helps to evenly distribute the fluid flow across the filter media.
Seals: These ensure a leak-free fit within the filter housing. They are usually made from materials resistant to hydraulic fluids, such as nitrile or Viton.
The primary function of the STAUFF filter element is to filter out contaminants from the hydraulic fluid. These contaminants, if left unchecked, can cause wear and tear on the hydraulic system's components, leading to system failure. By removing these contaminants, the filter element helps to extend the lifespan of the system and maintain its efficiency.
The filter element also helps to maintain the viscosity of the hydraulic fluid by keeping it clean. This ensures that the fluid can efficiently transmit power throughout the hydraulic system.
In summary, the STAUFF filter element plays a crucial role in hydraulic systems. It ensures the cleanliness and efficiency of the system, thereby contributing to its overall performance and longevity.
