Danfoss Gear Pumps, Cast Iron, D and XD Series

Features and benefits

The D Series pump blends the traditional Group 2 (SAE-A) and Group 3 (SAE-B) frame sizes in a single package with displacements from 7 to 45 cm3 (0.43 to 2.75 in3).

High strength cast iron construction allows consistently efficient performance and long life in continuous operation at 276 bar [4000 psi] and peak conditions of 303 bar [4400 psi].

Custom engineered bearings, pressure-balanced load plates, and viton seals optimize internal lubircation allowing for long life with intermittent fluid temperatures up to 115 °C [239 °F] and fluid viscosities as low as 8 mm2/sec (cSt) [36 SUS].

Compact three-piece design maximizes power density and creates one of the shortest multisection pumps (with up to four pumping sections) in the global marketplace.

Bearings located in the front flange increase radial/axial load carrying capability and eliminate the need for most bolt-on outrigger bearings.

D Series pumps can be coupled together to produce tandem, triple and even quadruple section units.

The interconnecting chambers accommodate fluid flow between sections and allow the number of inlet connections to be minimized. Systems that require operation with different fluids and/or reservoirs can be accommodated with sealed auxiliary covers between sections.
