Pumps & Regulators

Aircraft pumps and regulators in this category are indexed by complete designation, working medium and documented system role. The range includes hydraulic pumps, fuel-pump assemblies, starting pumps and associated regulating equipment. Common function words are not enough for selection because pressure, flow, drive and connection arrangements can differ between executions.

Hydraulic, fuel and starting-pump positions

Catalogue examples include 435F, 465A, 465D, 465K and 623ANM hydraulic pumps, as well as the 463B and 748A fuel-pump positions. The 726V is recorded as a starting pump. These identifiers refer to separate products; letters and suffixes remain significant even where the housing or general operating principle appears related.

Working medium and installation data must correspond

A request may need the system, fluid, drive type, direction of rotation, pressure and flow data, mounting pattern and connection details. Use parameters from the exact product record and applicable aircraft or engine documentation. Do not infer compatibility from a neighbouring designation or visible resemblance.

• record the complete pump or regulator number;
• identify the working medium and system;
• include documented pressure and flow data;
• state drive, mounting and connection details;
• add quantity, photographs and document needs.

Prepare a technically useful pump enquiry

Select the matching card to request verification of identity, condition, completeness, records, price and supply time. Fluid-cleaning components are organised under Aircraft Filters. Shut-off and control devices can be searched in Aircraft Valves.
