Hydraulic Pump Seal Kits

The main function of hydraulic pump seal kits is to prevent the leakage of hydraulic oil and the intrusion of external pollutants to ensure the stable operation of the hydraulic system and the normal operation of the machinery. Usually, it contains multiple types of seals, such as dynamic seals, static seals rotary seals, etc. They can provide customized solutions for different hydraulic pump and hydraulic cylinder models.

Hydraulic Pump Seal Kits-Ideal Mechanical Seal Solution

1. Application Advantages

Prevent leakage: The sealing kit can prevent hydraulic oil from leaking from the pump, protect the environment, and reduce resource waste.

Pollution protection: Prevent dust, moisture, and other impurities from the hydraulic system to prevent system performance degradation or damage.

Improve efficiency: Improve the working efficiency of the hydraulic pump by reducing internal leakage and maintaining system pressure.

Extend life: Reduce the wear of pumps or system components caused by contamination or leakage, and extend the service life of the equipment.

Easy maintenance: The standardized kit design simplifies the replacement process, making maintenance more convenient and quick.

2. Material Properties

Common sealing materials in hydraulic pump seal kits mainly include the following:

Nitrile Rubber (NBR)

This is one of the most commonly used materials with good oil and wear resistance. Suitable for most common hydraulic systems.

Fluorocarbon Rubber (FKM/Viton®)

It has high heat resistance and chemical resistance and can be used in high-temperature and high-pressure hydraulic systems.

Polytetrafluoroethylene (PTFE)

It has strong chemical resistance and is suitable for harsh working conditions. However, it has poor wear resistance and needs to be used in conjunction with other materials.

Polyurethane (PU)

It has excellent wear resistance and pressure resistance and is suitable for high-load occasions.

Polyether Ether Ketone (PEEK)

It has splendid heat resistance and can withstand higher temperatures and pressures.

3. Types

V-Ring Seals: A common hydraulic seal made of rubber or polyurethane, used for piston and rod sealing.

U-Cups: Used for guiding and sealing pistons or rods, with good wear resistance and self-lubricating properties.

Y-Seals: Used for bidirectional sealing, commonly used in hydraulic cylinders.

Wiper Seals: Remove the oil film on the sealing surface to maintain the sealing effect.

O-rings: A universal static seal suitable for a variety of hydraulic systems.

Rotary Shaft Seals: Used for sealing rotating shafts to prevent oil leakage along the shaft.

Composite Seals: Combine different materials and designs to meet specific application requirements.
