DTW rod wipers are a D-style single lip, snap-in design with a radial static sealing lip on the outside surface that maintains a positive sealing contact. An axial static seal lip on the external top side of the heel keeps the wiper tight in the groove and also serves as an additional static seal to prevent the ingress dust and contaminates around the outside of the seal. DTW wipers feature a slotted heel; vents on the inside edge to prevent the wiper trapping pressure or being pushed out by pressure in the event the rod seal has become damaged or has exceeded its service life. DTW wipers are currently available in metric sizes. For imperial, please see DSW rod wipers. For sizes not found in the DTW range, please check our SQW range

DX are a snap-in rod wiper that fit D-style rod wiper grooves. DX wipers have a patented profile with a single lip design and are vented on the inside edge. These profiles incorporate a rubber o’ring that maintains a robust static sealing contact in the groove. The o’ring also serves as an energiser and provides robust and long term preload on the dynamic wiper lip. In case of radial misalignment, the entire TPU wiper ring follows the eccentric movement as the relatively soft and flexible rubber o’ring energiser deforms to compensate.
DKB rod wipers are a medium to heavy duty double lip press-fit design with a rubber lip. The internal-facing wiper lip wipes excess fluid film from the rod on the extending stroke and allows this excess fluid to return under the rod seal on the retracting stroke. Double acting wipers therefore extend the service life of rod sealing systems. DKB wipers are available in metric sizes.

Wiper seals maintain sealing contact to the piston rod when the equipment is stationary and in use. Without a wiper seal, the retracting piston rod could transport contaminates into the cylinder which can adversely affect performance and service life of hydraulic systems.
GA and GC rod wipers are medium to heavy duty single lip press-fit design with a rubber wiping lip that protrudes from the shoulder. This design allows small radial cross sections and reduces the risk of contaminants adhering to the wiper lip. GC wipers have a design where mating surfaces are completely covered in rubber and are ideal in situations where electrolysis between two mating metal parts can cause corrosion.

DSW are a D-style snap-in rod wiper and have a single lip design and radial double bump static sealing lips on the outside surface that maintains a positive sealing contact with the rod. DSW wipers feature a slotted heel; vents on the inside edge that prevent the wiper trapping pressure or being pushed out of the groove by pressure in the event the rod seal has become damaged or has exceeded its service life.
Hydraulic cylinders operate in a variety of applications and environmental conditions, including exposure to dust, debris and outside weather conditions. To prevent these contaminates from entering the cylinder assembly and hydraulic system, wiper seals (also known as scrapers, excluders or dust seals) are fitted on the external side of the cylinder head.
Dr. Hans Bünting, CEO of RWE Innogy: “Construction of Thornton Bank wind farm is on schedule and is matching up to our expectations. This project shows that – when the conditions are right and long-term planning is possible – offshore wind energy can work on an industrial scale.” Owning a 26.7 percent interest, RWE Innogy is the largest private shareholder in Thornton Bank wind farm.
PA rod wipers are a heavy duty single lip press-fit design with a wiping lip that protrudes from the shoulder. This design allows for small radial cross sections and reduces the risk of contaminants adhering to the wiper lip. PA profiles are suitable for heavy duty off-highway applications and are available in metric sizes.
The turbines are set to generate approximately 500,000 megawatt hours (MWh) of electricity a year. This output meets the average annual energy needs of around 140,000 households in Belgium. RWE’s Dutch subsidiary Essent is responsible for the distribution of Thornton Bank 2 electricity.

When the wiper lip encounters resistance from stout contaminants adhered to the rod such as tree sap, dried mud or frozen rain, the profile twists as the rod retracts and increases the preload on the dynamic wiper lip. Therefore, DX profiles include the functionality of press-fit wipers as with the convenience of snap-in wipers. DX wipers are available in imperial sizes for D-style grooves.

Thornton Bank wind farm is situated some 30 kilometres off the coast of Belgium in waters up to 30 metres deep. The first phase of the wind farm went into operation in 2009. The six 5 megawatt plants of Thornton Bank 1 produced more than 450,000 MWh up to present. The third and final phase is to feature 24 wind turbines. Six of these were erected in 2012. They are also connected to the grid and are already producing electricity.
STW rod wipers are a light-duty single lip snap-in design with a double-stepped shoulder to firmly secure the wiper within the groove. STW wipers feature pressure relief ridges on the inside of the heel that prevent the wiper trapping pressure or being pushed out of the groove by pressure in the event the rod seal has become damaged or has exceeded its service life. STW wipers are available in metric sizes.
Thornton Bank wind farm is one of the largest project-financed offshore wind farms in Europe. In all, eight commercial European banks, the European Investment Bank and the German and Danish export credit agencies have provided approximately 900 million euros in financing and venture capital.
