Additel ADT 960 is a powerful hydraulic ultra-high pressure test pump designed for professional pressure calibration from 0 to 60,000 psi / 4,200 bar. This benchtop comparison pump combines exceptional pressure generation with a dual-piston system, a large 420 ml reservoir, precise fine adjustment and dedicated ultra-high pressure connections. It is designed for demanding calibration applications involving pressure gauges, indicators, transducers and other pressure measuring instruments.
The Additel ADT 960 is particularly suitable for applications where extremely high pressures and larger hydraulic workloads must be handled efficiently. Its integrated hand pump is used to fill the hydraulic system, while the high-pressure fine adjustment screw press provides smooth and controlled pressure generation. This combination enables pressures up to 4,200 bar to be generated manually without an external electrical power supply.
An integrated isolation valve separates the calibration volume from the check valve associated with the hand pump. Because check valves can become a potential source of leakage and maintenance, this design helps provide more stable measurements and reduces the influence of the hand pump mechanism during precision calibration.
The Additel ADT 960 uses Diethylhexyl Sebacate as its hydraulic pressure medium. Its 420 ml reservoir provides substantial capacity for demanding high-pressure calibration setups.

The Additel ADT 960 generates hydraulic gauge pressure from:
0 psi / 0 bar
to:
60,000 psi / 4,200 bar.
This exceptional pressure range makes the ADT 960 suitable for specialized industrial and laboratory calibration applications where conventional hydraulic pressure pumps can no longer provide the required pressure.
Typical devices under test include:
- Ultra-high pressure gauges
- Mechanical pressure gauges
- Digital pressure gauges
- Hydraulic pressure gauges
- High-pressure test gauges
- Precision pressure indicators
- Pressure transducers
- High-pressure sensors
- Industrial pressure measuring instruments
With a maximum pressure of 4,200 bar, the ADT 960 provides a manual pressure source for some of the most demanding pressure calibration applications.
Designed for Large-Volume Workloads
The Additel ADT 960 is designed to efficiently pressurize large-volume hydraulic workloads.
A high-pressure calibration system may contain significant internal volume due to:
- Large devices under test
- Long high-pressure tubing
- Reference pressure instruments
- Multiple adapters
- Calibration manifolds
- Complex hydraulic connections
The integrated hand pump efficiently fills the connected system before the fine adjustment screw press is used for final high-pressure generation.
This design significantly simplifies the preparation of larger hydraulic calibration systems.
Dual-Piston System
A key feature of the Additel ADT 960 is its dual-piston pressure generation system.
The hand pump provides approximately:
3.72 ml per stroke.
This allows the hydraulic circuit to be filled efficiently.
The fine adjustment piston provides approximately:
2.5 ml piston volume.
Once the system has been filled and initially pressurized, the high-pressure fine adjustment screw press is used to approach the required calibration point.
The combination provides efficient filling together with controlled ultra-high pressure generation.
Smooth Pressure Adjustment
Precise adjustment is especially important when working at pressures of several thousand bar.
The Additel ADT 960 incorporates a high-pressure fine adjustment screw press that allows pressure to be increased and decreased smoothly.
This helps the operator approach individual calibration points in a controlled manner.
Smooth adjustment is particularly useful when calibrating:
- High-resolution pressure gauges
- Precision pressure indicators
- Ultra-high pressure transducers
- Reference pressure instruments
- High-pressure sensors
Once the target pressure has been reached, the system should be allowed to stabilize before measurement values are recorded.
Isolation Valve for Stable Measurements
The Additel ADT 960 incorporates an isolation valve that separates the calibration volume from the check valve associated with the hand pump.
This is particularly important during precision comparison calibration.
Check valves can represent a potential source of leakage and maintenance in hydraulic hand pumps.
Once the hydraulic system has been filled and pressurized, the isolation valve separates the calibration volume from this section of the pump.
This helps provide:
- More stable pressure measurements
- Reduced influence of check valve leakage
- Improved conditions for comparison calibration
- Reduced potential maintenance
- Better isolation of the calibration volume
The concept is particularly valuable when high-resolution reference pressure instruments are used at ultra-high pressures.
Diethylhexyl Sebacate Pressure Medium
The Additel ADT 960 uses:
Diethylhexyl Sebacate
as its hydraulic pressure medium.
A 250 ml bottle is included with the pump.
The specified hydraulic medium is an important part of the ultra-high pressure system and should be used according to the manufacturer’s instructions.
Before connecting a device under test, compatibility between the instrument and pressure medium should always be verified.
Additional Diethylhexyl Sebacate is available from Additel as model 9201.
Large 420 ml Reservoir
The Additel ADT 960 incorporates a large hydraulic reservoir with a capacity of:
420 ml.
This substantial reservoir capacity supports the pump’s intended use with larger hydraulic workloads.
A large reservoir is particularly useful when the calibration setup includes:
- Large pressure instruments
- Long pressure lines
- Multiple pressure components
- High-pressure manifolds
- Additional adapters and fittings
The reservoir capacity, combined with the integrated hand pump, makes the ADT 960 suitable for demanding stationary calibration applications.
Ultra-High Pressure Connections
At pressures up to 4,200 bar, suitable high-pressure connections are essential.
The Additel ADT 960 therefore uses dedicated ultra-high pressure connections.
The standard ADT 960-AF configuration provides:
Autoclave F-250-C, 9/16″-18 UNF female
connections for the test gauge and reference gauge.
The pump provides two pressure ports.
These connections are specifically intended for the demanding pressure range of the ADT 960.
Additel also specifies 1/2 BSP female and M20 × 1.5 female connections as available upon request.
Professional Comparison Calibration
The Additel ADT 960 is designed as a professional comparison pressure test pump.
A typical calibration setup consists of:
Additel ADT 960 + Reference Pressure Instrument + Device Under Test
The reference instrument and device under test are connected to the pump.
The integrated hand pump is initially used to fill the hydraulic system.
The high-pressure fine adjustment screw press is then used to increase the pressure toward the required calibration point.
The isolation valve separates the calibration volume from the hand pump check valve.
After sufficient pressure stabilization, the indication of the device under test can be compared with the traceable reference pressure.
The procedure can be repeated at several increasing and decreasing pressure points according to the applicable calibration method.
Ultra-High Pressure Gauge Calibration
The Additel ADT 960 is particularly suitable for calibrating pressure gauges with exceptionally high measuring ranges.
Typical applications include:
- Mechanical high-pressure gauges
- Digital high-pressure gauges
- Hydraulic pressure gauges
- Ultra-high pressure test gauges
- Precision pressure indicators
- Specialized industrial pressure instruments
The ADT 960 generates the required hydraulic pressure but does not itself provide the traceable reference pressure value.
For professional calibration, it must therefore be combined with a suitable reference pressure instrument covering the required pressure range.
The achievable measurement uncertainty depends on the complete calibration system, including the reference standard, pressure stability, environmental conditions, pressure medium, calibration procedure and all other relevant contributions to the measurement uncertainty budget.
Pressure Transducer Calibration
The Additel ADT 960 can also provide the pressure source for ultra-high pressure transducer calibration.
A suitable reference pressure instrument measures the applied hydraulic pressure.
The output signal of the pressure transducer can simultaneously be measured using appropriate electrical measurement equipment.
Increasing and decreasing pressure sequences can be used to evaluate characteristics such as:
- Measurement deviation
- Repeatability
- Hysteresis
- Zero behavior
- Span behavior
The fine adjustment screw press supports controlled positioning of individual pressure points throughout the calibration range.
Robust Benchtop Construction
The Additel ADT 960 is designed for professional laboratory use.
The ram and adapters are manufactured from:
stainless steel.
The body combines:
stainless steel, aluminum and copper.
Seal materials include:
Buna-N, PTFE, copper alloy and aluminum alloy.
The pump dimensions are approximately:
455 × 380 mm base
with a height of approximately:
175 mm.
The weight is approximately:
15 kg / 33.1 lb.
This robust construction makes the ADT 960 suitable for permanent installation in professional ultra-high pressure calibration environments.

Additel ADT 960 vs. Additel ADT 959A
The Additel ADT 960 and Additel ADT 959A are both hydraulic ultra-high pressure benchtop pumps designed for professional comparison calibration.
The most important difference is the maximum generated pressure.
The Additel ADT 959A generates pressure up to:
40,000 psi / 2,800 bar.
The Additel ADT 960 extends the pressure capability to:
60,000 psi / 4,200 bar.
This represents an additional 1,400 bar of maximum pressure capability.
Both pumps are designed around a dual-piston concept that combines efficient filling of larger hydraulic volumes with controlled fine pressure adjustment.
Both use Diethylhexyl Sebacate as the hydraulic pressure medium and incorporate large 420 ml reservoirs.
For applications with a maximum pressure requirement of 2,800 bar, the ADT 959A provides an ultra-high pressure solution.
For specialized applications extending beyond this range and requiring pressures up to 4,200 bar, the Additel ADT 960 provides the additional pressure capability.
Additel ADT 960 vs. Additel ADT 946A
The difference between the Additel ADT 960 and ADT 946A is even greater.

15,000 psi / 1,000 bar.
The Additel ADT 960 reaches:
60,000 psi / 4,200 bar.
The ADT 946A is therefore designed for conventional high-pressure hydraulic calibration, while the ADT 960 addresses specialist ultra-high pressure applications.
Another significant difference is the connection technology.
The ADT 946A uses convenient hand-tight connections in common NPT, BSP and M20 configurations.
At up to 4,200 bar, the ADT 960 instead uses dedicated Autoclave F-250-C ultra-high pressure connections.
The appropriate pump should therefore be selected according to the required maximum pressure, workload volume, connection system and calibration application.
