209-5921 2095921 CA2095921 Hydraulic Pump Seal Kit For E E330 E330C
Seal ring
◎Main seal, used in multi-stage cylinders, strong tear resistance,
high tensile strength, special impact resistance, not easy to tear
and damage; ◎ Good elasticity and good sealing effect, more
suitable for coal and mining industry; ◎Opening the secondary lip
of the ring to support the function. At the same time, a small
amount of oil film extends from the annular lip of the opening to
improve the lubriEion condition of the subsequent order; ◎With the
drum ring, it is safer.
Advantages:
1, Focus on the development and manufacture of hydraulic seals for
20 years.
2, A great number standard parts in stock .
3, Customized seasl service .
4, CNC Machining Seals without mould cost ,fast dispatch.

1. Product introduction
The availability of highly developed nitriles resistant sa to oil
water and many other fluids has widened the field of unit seal
appliEion to a great extent , and provided precise contions of
machining accuracy finish and lubiEion are maintained in the
mechaisms to which these seals are applied they are capable of
giving excellent service within a wide range of temperatures and
speed conditions.
It is hoped the information given here will help the designer and
user to choose the correct type of sealing unit for his appliEion
,A publiEion of this kind cannot cover every aspect of fluid
sealing ,nor can it answer every puery which is likely to arirsre
,When enpuiring please state
- The nature of appliEion
- Fluid to be sealed
Minimum , maximum and working fluid pressures
Minimum , maximum and working teperatures
Shaft speed and lubricant used

3.The Role of Each Part
A. Lip end (sliding surface): The lip end is in the shape of a wedge and presses the shaft
surface at the end to seal the fluid.
B. Sealing lip: It is a flexible elastomer, designed to ensure that it can
maintain a stable sealing effect under the influence of mechanical
vibration and pressure fluctuations of the sealing fluid, and
maintain a stable contact state with the shaft surface at the end
of the lip effect. In addition, the spring can increase the
pressing force of the sealing lip on the shaft, which prevents the
intrusion of dust.
C. Dust-proof lip: The dust-proof lip is an auxiliary lip that is not connected to
the spring, and plays the role of preventing dust intrusion.
D. Fitting part: While fixing the oil seal to the cavity hole, the fitting part
plays the role of preventing fluid leakage and intrusion from the
contact surface between the outer peripheral surface of the oil
seal and the inner surface of the cavity. In addition, the metal
skeleton plays the role of fixing the oil seal on the cavity and
maintaining the matching force.
