Surface Shaping

Revolutionize Your Hydraulic Sealing Surfaces with SHS

Surface shaping in hydraulic systems has taken a giant leap forward with meso structures. These surface structures, with depths measured in micrometers and lengths in millimeters, offer an ingenious solution. They enable hydrodynamic pressure build-up while preserving the integrity of hydrostatic seals.

Through rigorous investigations with Caspar FSTI, we've uncovered the transformative potential of meso structures across all three sealing interfaces: cylinder block/valve plate, piston/bushing, and slipper/swash plate.

Published test rig results are nothing short of remarkable:

  • A waved valve plate can slash power losses by over 10% /5-6/.

  • A stepped slipper can reduce startup torque by a staggering 80% while simultaneously boosting efficiency at low-power conditions by more than 20% /1-3/

  • A uniquely shaped piston, tested in our prototype, cut piston losses by an impressive 20% /4/.

SHS offers you the opportunity to evaluate if your pump is a candidate for these game-changing surface shapes and, crucially, to design the perfect shape for your specific application. This is especially advantageous in the realm of electrification, where frequent startups and low-speed operations are the norm and can greatly benefit from these innovative surface configurations.

And here's the kicker: With the right implementation, the cost of production can be comparable to regular parts, as it eliminates the time-consuming lapping process.

At SHS, we're not just shaping surfaces; we're reshaping the future of hydraulic systems. Join us in revolutionizing efficiency, performance, and cost-effectiveness in your hydraulic applications.
