Dark Green Polyurethane B7 Hydraulic Pump Oil Seal

B7 type dark green polyurethane PU piston seal for pump truck or heavy mobile machinery hydraulic oil seal

1.  The profile B7 Ultrathanpiston seal is a lipseal which fits tightly in the groove. This seal may be used for all applications where the physical properties of normal or fabric reinforced elastomers are insufficient.

2.  Range of application
Mainly for the sealing of pistons in heavy duty applications in mobile and stationary hydraulics.

Operating pressure ≤400 bar
Operating temperature -35°℃ to +110℃
Sliding speed ≤0.5m/s
Media Hydraulic oils based on mineral oil

3. Compounds
The Ultrathan P5008 compound is a Parker material based on polyurethane with a hardness of approx. 93 Shore A. Its main advantages in comparison with other poly urethane materials currently available on the market are the increased heat resistance and the lower compression set.
For media containing water, we recommend our hydrolysis-resistant polyurethane compound P5001.

7. Factory and packaging

in case of specal operating conditions (specific pressure loads, temperature, speed, use in water. HFA HFB fluids etc.), please contact our consultancy service for a selection of the material and design best suiting your particular application requirements.

8. Installation

The seals should have an axial clearance (see columns H and 1). To avoid damage at the sealing lips, the seals should not be pulled over sharp edges during installation. Normally these seals may be snapped into closed grooves. Where access is restricted special assembly tools may be required. Proposals for the design of such tools wil be provided on request.

in case of special operating conditions (speafic pressure loads. temperature, speed, use in water, HFA. HFB fuids etc.).please contact our consutancy service for a selection of the material and design best suiting your particular application requirements.
