Fluid Power
Fluid power is the utilization of fluid or gas under pressure to generate, control, and transmit power. It can be divided into two major categories: Hydraulics uses liquid, such as oil or water, whereas Pneumatics uses air or other gases. Hydraulic or Pneumatic cylinders and motors are commonly utilized in industrial applications and our daily lives.
In industrial applications, companies like Caterpillar, Komatsu, and Bobcat utilize hydraulic systems in their loaders and excavators to perform tasks on construction sites. In our everyday lives, we can easily encounter hydraulic systems in office chairs and barber chairs. WinTek offers hydraulic pumps and cylinders. Please feel free to contact us for further information.
Hydraulic Cylinder
Hydraulic cylinder, also known as hydraulic motor, is an actuation device that makes use of a pressurized hydraulic fluid to produce forces to move cylinder in a linear direction. Hydraulic cylinder is consisted of cylindrical barrel, piston, and piston rod. Within the cylinder, there are multiple seals that are installed and each of them serve its’ function whether it is to prevent leakage of the hydraulic fluids, exclude outside contaminants, or provide protection to the piston and rod.
At WINTEK, our hydraulic sealing product is the best sealing solution for your application ranging from rod seals, piston seals, wiper seal series, and pin dust seal. For notice, our WP3, WP6-DKB, WH series- DKBI, DKI, DWI) are widely used in construction machinery like Caterpillar, Komatsu and in other brands.

Hydraulic Pump
A hydraulic pump is one of the hydraulic drive systems, which can be either dynamic or static. It converts mechanical power into hydraulic energy. The flow is generated from the power overcoming the pressure induced by the load at the pump outlet. When the hydraulic pump operates, a vacuum is created at the pump inlet, forcing liquid to move from the reservoir into the inlet line and to the pump outlet. This liquid is then delivered to the pump outlet by mechanical action, where it is forced into the hydraulic system. Pumps offer a wide range of options and features, including high pressure, long life, and quiet operation, and are utilized in various applications.
A hydraulic pump oil seal is a crucial component that prevents hydraulic fluid from leaking. It acts as a barrier between the rotary and the stationary part. At WinTek, we design hydraulic pump oil seals with the ability to withstand high pressure, resist high temperature, and chemical substances, providing effective sealing performance in pump applications.

BONDED SEAL
The bonded seal is a metal washer with vulcanized elastomeric rubber inserted for the usage in high pressure applications where other means of sealing are inappropriate. It consists of a metallic ring to prevent over-compression and limits deformation of the inserted elastomeric rubber pad. The bolt torque is reduced with no loss of tightening load. Material: NBR, FKM, EPDM

ANTI-PRESSURE SEALS
Anti-Pressure seals are specifically designed for the use in pressurized operating conditions, which pressure is in the range of 3~10 Bar.
Type N Series:
Anti-pressure design is used for high pressure application. The anti-pressure range (3 bars ~ 10 bars) depends on the shaft speed, length and thickness of flex section. Application typically for hydraulic pumps, oil pumps, and hydraulic motors.
PTFE ASSEMBLY SEAL
PTFE assembly seal design features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. The PTFE sealing lip provides temperature capability and excellent chemical resistance and can function at much higher surface speed with low friction. The seals are used in demanding applications where the operating conditions exceed the capabilities of elastomeric seals. This design’s versatility makes it suitable for hydraulic pump and motor. It also has a wide range of applications including: Motors, Gear Boxes, compressor and vales.
