PDYY / PDYC / PDYE / PDYS pumps for high-speed cylinder lubrication on two-stroke engines

Designed for high-speed cylinder lubrication on two-stroke engines, the PDY pumps use an existing oil supply system or drive pump unit. Engine electronics trigger the pre-loaded pumps by activating the solenoid valve. The exact stroke volume can be synchronized with the moving engine piston. Ignition timing can be adjusted to reach various piston stress areas with oil. 

PDYY and PDYC pumps feature a baseplate configuration with 6 or 8 outlets. The PDYE serves engines with 6, 8 or 10 lubrication points per cylinder. PDYS pumps have double-stroke functionality for use on small-bore engines with only 4 outlets per cylinder.
