What is the ATF Fuel Pump Test Rig DTSN-82?

The ATF Fuel Pump Test Rig DTSN-82 is a precision test system for running-in and performance testing of the centrifugal fuel booster pump DTSN-82, which is part of the fuel injection system of aircraft. It tests the pump at different input absolute pressures and corresponding delivered flows at varied RPM.

The rig uses Aviation Turbine Fuel (ATF) as the working fluid, maintained at NAS 1638 Class-4 cleanliness. Fluid density at 20°C is 0.78 gm/cm². Permissible fluid temperature range is 20 to 120°C.

What is the flow range of the DTSN-82 test rig?

The rig supports flow through the UUT (unit under test) from 500 to 150,000 LPH. Absolute pressure at the inlet of the UUT ranges from 0.2 to 3.2 kg/cm².

What are the key safety features of the DTSN-82 test rig?

The rig includes emergency shutdown, interlocking of drives, leak-tested components and final assembly, and heat/moisture-resistant wiring routed per IS norms through cable trays.

What power supply does the DTSN-82 test rig require?

The rig requires 415V ±10%, 3-phase, 50 ±2 Hz power supply.

The ATF Fuel Pump Test Rig DTSN-82 is purpose-built for running-in and functional testing of the centrifugal fuel booster pump DTSN-82, which is a critical component of the fuel injection system in military and civil aircraft.

The rig creates controlled test conditions by pressurising the ATF tank using shop air and a vacuum pump, achieving inlet absolute pressures from 0.2 to 3.2 kg/cm² at the unit under test (UUT). Delivered flow is measured over the full operating range of 500 to 150,000 LPH at varied drive shaft RPM up to 1000.

ATF fluid cleanliness held to NAS 1638 Class-4 throughout the test cycle.

A circulating water cooling system maintains the working fluid within the permissible temperature envelope of 20 to 120°C. All wiring is heat- and moisture-resistant, coded, and routed through cable trays per IS norms. Emergency shutdown and drive interlocks are standard.

Key Features

Built for ATF environments.

Four core engineering disciplines that define the DTSN-82 test rig.

Feature · 01

ATF-Grade Wiring & Routing

All interconnect wiring is heat-resistant and moisture-resistant by specification. Wires are properly coded, bunched, and routed through dedicated cable trays in compliance with IS norms — critical in an ATF vapour environment.

Heat-Resistant · IS Norms · Cable Tray Routing

Feature · 02

Leak-Proof Assembly

All individual components are leak-tested before assembly. The complete final assembly undergoes a further leak test under operating pressure — essential when working with aviation turbine fuel at pressures up to 3.2 kg/cm².

Component Leak Test · System Leak Test · ATF Tight

Feature · 03

Safety Interlocks & Emergency Shutdown

Emergency shutdown is hard-wired and independent of the control system. Drive interlocks prevent the pump from being started unless all pre-conditions (fluid level, temperature, cleanliness monitoring) are met — protecting both the UUT and the operator.

E-Stop · Drive Interlock · Independent Safety Circuit

Feature · 04

Industrial Finish & Aesthetic

Panels are painted in a suitable colour with a mat finish. All structural elements and fluid components are painted in a coordinated colour scheme — presenting a professional, inspection-ready appearance for defence and aerospace customer environments.

In Depth

The complete technical read.

Engineering narrative for test and MRO engineers specifying a centrifugal fuel pump test rig.

01 — The UUT

The DTSN-82 centrifugal fuel booster pump

The DTSN-82 is a centrifugal fuel booster pump forming a critical part of the fuel injection system on certain military aircraft. Its role is to maintain positive fuel pressure at the inlet of downstream fuel injection components across the flight envelope — from sea-level ground operation to altitude conditions where fuel tank pressure may drop below ambient.

02 — ATF Circuit

ATF pressure and temperature control

Shop air and a vacuum pump pressurise or depressurise the ATF tank to set the absolute inlet pressure at the UUT — from as low as 0.2 kg/cm² (simulating altitude cavitation margin) to 3.2 kg/cm² (boosted ground conditions). A circulating water heat exchanger controls the ATF temperature throughout the test window of 20 to 120°C.

03 — Cleanliness

NAS 1638 Class-4 fluid cleanliness

Aviation fuel system components are sensitive to particulate contamination. The rig maintains ATF cleanliness better than NAS 1638 Class-4 throughout the test cycle using appropriate filtration in the recirculation circuit. This protects the precision clearances inside the UUT and ensures test results are not corrupted by contamination-induced wear during the running-in phase.

04 — Safety

ATF safety — shutdown and interlocks

Aviation turbine fuel is flammable. The rig's safety architecture includes a hard-wired emergency shutdown independent of the control PLC, interlock chains on all drives that prevent start unless fluid conditions are confirmed, and heat- and moisture-resistant IS-compliant wiring throughout. Component-level and final assembly leak tests are conducted under ATF before commissioning.
