Gardner Denver launches hydraulic trunk accessory
Gardner Denver recently introduced a new hydraulic trunk accessory for its widely adopted GD70 oil-lubricated piston compressor. The new offering allows customers to purchase the GD70 preassembled with a hydraulic trunk, enabling hydraulic drive capability for liquid bulk off-loading applications.
The one-piece, cast-iron trunk is engineered for durability and ease of use, featuring a removable guard with air ventilation openings, an SAE “A” two-bolt flange, and optional coupler configurations, Gardner Denver reported. Developed in close collaboration with Gardner Denver’s distributor partners, the hydraulic trunk is designed to simplify installation, improve maintenance access, and support more efficient operations.
“The GD70 Hydraulic Trunk is a gamechanger for operators in the liquid bulk transport industry,” Carl Kruthoff, Gardner Denver transport product manager, said in a news release. “It combines rugged construction with thoughtful design to simplify maintenance and improve operational efficiency.”
- Removable guard with air ventilation for:
- Easy access to shaft coupling and seal
- Quick coupler and set screw adjustments
- Shaft speed verification using a laser tachometer
- One-piece cast iron construction for long-term durability
- SAE “A” two-bolt motor flange (supports hydraulic motors up to 35 lbs.)
- Available with or without coupler:
- ⅞” or 1” round with ¼” key motor shaft coupler
- KTR Rotex 28 and spider coupler options
- Compact 5¾” trunk length for space-constrained installations
The GD70 compressor, originally launched in 2021, is a two-cylinder, single-stage, oil-lubricated piston compressor designed for pressure offloading of bulk liquids such as solvents and resins. Its in-line design offers a compact footprint, allowing room for additional equipment on mobile units. The GD70 continues to be available as a standalone unit or with the new hydraulic trunk preassembled.
