The Maren ProPak 2R350 Two-Ram Baler is built with performance, longevity, and operator safety in mind. Here’s a deeper look at the engineering features that set it apart.
1. High-Efficiency Hydraulic System
The ProPak 2R350 uses double or triple 100 gpm pressure-compensated piston pumps, rated for 6,100 psi but operated at 4,500 psi to extend pump life and reduce stress on components. Its flooded suction pump design prevents dry start-ups and makes maintenance easier.
This hydraulic architecture ensures:
- Faster baling cycles
- Greater energy efficiency
- Longer system life
- Reduced heat buildup
2. Superior Shearing & Material Processing
The baler features:
- Hardened and ground tool-steel shear blades (reversible for double life)
- Extended cutting profiles to reduce jams
- Automatic shear-jam prevention with multiple clearing attempts before alerting the operator
- Features & Benefits Sheet - Pro…
This results in smooth operation across challenging materials like plastics, aluminum, magazines, and metals.
3. Precision Bale Size Control
Bale size is adjustable from 38”–51” in width, allowing operators to maximize trailer and container loading efficiency. Combined with:
- Wire placement automation
- Material-specific dwell time adjustments
- Load-above-platen mode (to reduce spring-back)
4. Serviceability & Safety Built In
Maren designed the baler with multiple access points:
- Hinged sidewall service doors
- Interlocked maintenance doors
- External grease points
- Sensors for low oil, clogged filters, and over-temperature conditions
These features reduce downtime and ensure operators can service the machine safely and efficiently.
5. Structurally Superior Frame
With a shipping weight approaching 93,750 lbs, the ProPak 2R350 is built to withstand decades of industrial abuse. Its reinforced chassis and deep ram penetration (to within 8" of the end wall) increase bale density and durability under heavy loads.
