The Bucher PM-3530 4-Way Hydraulic Power Unit is a 12V HPU with two double-acting circuits in a single pump — built for wrecker bodies and other multi-cylinder jobs. The 6-quart polyethylene reservoir feeds two power-up / power-down sections, so one HPU runs both the boom and the wheel-lift cylinders independently.

Why use a 4-way HPU instead of two separate 2-way pumps?

One reservoir, one motor, one set of wiring — half the install footprint and half the failure points. The 4-way's two circuits run from the same fluid supply, so you don't have to maintain two separate reservoirs or worry about one circuit running dry while the other still has oil.

  • 12V DC, 4-Way (Power All) — two double-acting circuits
  • 6-quart high-density polyethylene reservoir
  • 2,500 PSI operational pressure
  • 1.5 GPM max oil flow
  • #6 SAE hose connections, 9/16 in SAE o-ring valve ports
  • Operating temp: -20°F to 130°F
  • Recommended fluid: ATF (Automatic Transmission Fluid)
  • Adjustable relief valve set at 2,500 PSI
  • Bucher PM-3530 — made in USA, 100% tested

For 6-circuit wrecker jobs that add open/close to up/down/in/out, see the Bucher 6-Way HPU (PM-3530-3ST). For single-circuit applications, see the Bucher 2-Way HPU (PM-3551).

    We use another pump on our truck that is twice as expensive and this pump outperforms it

  2. Ethan Hardinger

    I can't say enough about how reliable these pumps are

  3. Jason

    It works great
