Compactor Hydraulic Pumps

Replacement hydraulic pumps for industrial trash compactors — gear, vane, and piston pumps in OEM-equivalent specs. Replacements for Marathon, PTR, Wastequip, Harmony, and SP Industries hydraulic systems. Standard pumps ship same business day.

What this page covers

The pump is the heart of the compactor's hydraulic system — driven by the motor, it converts rotational motion into hydraulic pressure that drives the ram cylinder. Pump types fall into three families: gear pumps (most common, simplest, lowest cost), vane pumps (mid-range, quieter), and piston pumps (highest pressure, used in heavy-duty applications).

Most compactor pumps fail by gradual wear — internal clearances widen, efficiency drops, and the ram cycles slower. The warning sign is usually a longer cycle time before complete failure. PRT stocks OEM-equivalent replacement pumps for all common compactor brands; rebuild kits are also available for some pump models.

How to choose

Identify the pump by displacement (gallons per minute or cubic inches per revolution), pressure rating (PSI), drive style (close-coupled to motor, foot-mount with belt drive, or through-shaft), and OEM part number. PRT customer service can confirm a direct replacement.

If your existing pump is discontinued, PRT can recommend a current-production equivalent that fits into the same mounting location with the same displacement and pressure rating.

Hydraulic pump types

  • Gear pumpsMost common — simple, reliable, fixed displacement.
  • Vane pumpsQuieter than gear pumps, mid-range pressure capability.
  • Close-coupled pumpsDirect motor-flange mount for compact power units.
  • Foot-mount pumpsBelt-drive installations with separate motor and pump.

Frequently asked questions

How do I know if my compactor's hydraulic pump is failing?

Gradual symptoms: ram cycle time gets longer, ram doesn't reach full compaction pressure, hydraulic system runs hotter than normal. Test by measuring pump output flow at operating pressure; if flow is 75% or less of spec, the pump is worn out.

Are PRT hydraulic pumps interchangeable with original Marathon or PTR pumps?

Yes for most models. Pump dimensions, displacement, and mounting are standardized across brands at the same size class. PRT can confirm a direct equivalent or recommend a current-production replacement.

How long does a compactor hydraulic pump last?

10,000-25,000 hours depending on operating conditions. Clean hydraulic oil extends pump life dramatically; contaminated oil destroys pumps in 3,000-5,000 hours. Oil cleanliness is the single biggest factor in pump life.
