Customized sealing solutions as standard - Dosing pistons

Simple retrofit solution, quick problem solver

D1P seal
D1P seals

SKF D1P seals for dozing pistons are highly cleanable and offer precision sealing performance, stable fit in the piston housing. Featuring an elastomer sealing lip and a geometric design, that provides:

  • Good sealing ability, reliable performance in contact with different processed foods and beverages
  • Straightforward retrofit, can be adapted to any kind of housing

Frequent downtimes necessitating costly replacement

D2P seal
D2P seal

SKF D2P seals for dozing pistons are a reliable solution when seals are exposed to highly abrasive products, cleaning chemicals, high pressures and speed. This meander spring-energized thermoplastic lip seal is filled with silicone to keep contaminants out of the spring cavity. The seals are very easy to clean. When PTFE materials are used, D2P seals will resist high temperatures.

  • Increased performance given technology upgrade*
  • High chemical and thermal resistance
  • Reduced wear despite abrasive food products
  • Less costly replacement  due to reduced friction on the cylinder counter face

This seal used in existing arrangements requires mechanical modifications. Please contact your SKF sales partner or distributor.

Increased performance with simple maintenance

D3P seal
The D3P sealing system design enables simple screwing instead of snap-into for simplified maintenance

SKF D3P sealing system for dozing pistons is a complete thermoplastic piston for filling cylinders, installed directly on the driving rod. Made of SKF Ecowear and a variety of SKF Ecoflon compounds, the sealing system simultaneously provides a sealing and guiding effect for reduced maintenance. O-rings act as elastic energizing elements to keep contaminants from getting trapped, and can be manufactured in different elastomeric materials according to the application requirements

Benefits are:

  • Increased performance given technology upgrade
  • Significantly simplified maintenance
  • Improved clean ability
