Hydraulic Pumps<br />

<strong>Caterpillar</strong> offers a variety of hydraulic pump types and sizes that<br />

are matched to the pump drives available on <strong>Caterpillar</strong> engines.<br />

Fixed displacement gear pumps are available in three sizes for basic<br />

requirements. Variable displacement piston pumps with load sensing<br />

controls are available in two sizes for use in circuits with closed<br />

center valves where energy conservation is a priority. Hydrostatic<br />

pumps, typically used for propel applications, are available in two<br />

displacements.<br />
