Wiper WS-D31
Description
The WS-D31 is a double-acting, o-ring energized, rod wiper/excluder designed to include two different unique wiping lip geometries. The two lips combine to scrape debris from the rod and contain residual oil on rod extension, as well as allowing oil to pump back into the cylinder. Due to the good sliding properties of PTFE, this wiper is suitable for short stroke cylinders with high running speed and high stroke frequency. The o-ring energizer provides the force necessary to maintain the engagement of the wiping lips against the sliding surface and allow the wiper to adjust for deflection. The WS-D31 works well paired with rod seals that support the requisite dynamic pressure pump-back, like the RS-11 rod seal. When paired, they produce a sealing system capable of handling higher speeds, large range of fluid compatibilities, and temperature range of service. For other rod seal arrangements with this wiper, it is necessary to make sure the rod seal will provide proper pressure pump-back, or alternatively vent the system.

Installation instruction
WS-D31 wipers can be installed in closed and split grooves. Installation in closed grooves is dependent on the rod diameter, the cross-section of the wiper and on the cord cross-section of the O-Ring.
Installation in closed groove:
| Rod diameter: | O-ring cross section: |
| > 30 mm. | 1,78 mm |
| > 30 mm. | 2,62 mm. |
| > 40 mm. | 3,53 mm. |
| > 50 mm. | 5,33 mm. |
| > 110 mm. | 6,99 mm. |
| > 140 mm. | 8,4 mm. |
