  • R8M / R8D — fixed displacement, equivalent to Staffa HMB — 80–13,000cc/rev across frame sizes H1–H9, up to 270 bar continuous, speeds from around 130rpm continuous on the largest frames up to 950rpm on the smallest — high torque, low-speed motors for heavy-duty winches, cranes, and mining equipment.
  • R8C — dual displacement, equivalent to Staffa HMC — 69–5,326cc/rev across frame sizes H1–H7, up to 270 bar continuous (310 bar intermittent, 350 bar peak), torque up to 22,200Nm at the largest frame, speeds down to 1–5rpm minimum and up to 1,500rpm on the smallest sizes — selectable high/low-speed operation for applications that need both torque and travel speed from the same motor.
  • HC / HCD — single displacement, high power density, equivalent to SAI GM series — 40–1,625cc/rev across frame sizes HCD05–HCD5, up to 300 bar continuous (420–450 bar peak/hydrostatic), speeds up to 1,500rpm continuous (2,200rpm peak on the smallest sizes) — compact swivelling-block design for high-pressure, space-constrained installations.
