The Sauer Danfoss 45 series ERR ERL hydraulic pump family is engineered for reliable high-pressure performance in mobile and industrial hydraulics. Models ERR100, ERR130, ERR147, ERL100, ERL130, ERL147 piston pump deliver robust displacement control, low internal leakage and proven volumetric efficiency. Built with reinforced casings, heavy-duty swashplate assemblies and advanced sealing, these pumps resist pressure spikes, support explosion-protected installations and keep operating in extreme temperatures and contaminated environments. All units are supplied with a one-year warranty.
In practical systems the 45-series proves ideal where continuous duty and transient load resilience matter. Typical applications include primary drive pumps on mid-sized excavators, hydrostatic traction drives on large tractors, and high-flow systems on mining loaders. Example integrations: John Deere tractors and harvesters (www.deere.com), Caterpillar excavators (www.cat.com), Komatsu wheel loaders (www.komatsu.com), Liebherr mining shovels (www.liebherr.com), Volvo construction machines (www.volvoce.com) and Sandvik surface miners (www.rocktechnology.sandvik). For installation, match pump displacement to system flow requirements, fit correctly sized filtration and cooling, and specify explosion-proof options when operating in hazardous zones.
Technical operators benefit from the ERR/ERL design’s ability to reduce heat generation under high duty cycles and to tolerate pressure transients when paired with accumulators or dampers.

FAQ
Q1 — What is the primary difference between ERR and ERL?
A1 — ERR and ERL variants differ in shaft/mounting and internal porting options to suit system layouts while sharing similar hydraulic performance.
Q2 — Can these pumps handle pressure spikes common in mining?
A2 — Yes — reinforced housings and correct system dampening allow safe operation under transient spikes.
Q3 — How to maximize service life?
A3 — Maintain ISO cleanliness, correct fluid viscosity, timely filter changes and adequate cooling.
