PDYY / PDYC / PDYS pumps

For lubrication of high-speed cylinders of two-stroke engines

Designed to lubricate high-speed two-stroke engine cylinders, PDY pumps utilize the existing oil supply system or the drive pump unit. The engine's electronics activate the pre-filled pumps by activating a solenoid valve. The precise delivery volume can be synchronized with the engine's piston movement. Ignition can be adjusted to deliver oil to different piston loading zones.

The PDYY and PDYC pump support panels have 6 or 8 outlet ports. PDYS pumps feature a dual-stroke function for use in engines with small-bore cylinders that have only 4 outlets per cylinder.

Features and Benefits

  • Precise oil dosing within milliseconds
  • Load-dependent lubrication
  • Modular design for easy installation and maintenance
  • Prevents over-lubrication, deposits, excessive smoke and CO emissions2
  • Oil savings up to 40 %
  • Possibility of modernization

Application areas

  • Shipbuilding
