Pneumatic calibration pump Additel ADT992

high-pressurefor pressure and vacuum

Overview
Portable pneumatic pressure pump available in 50 and 70 bar versions. Designed to generate and stabilize pressure quickly on-site as a modern alternative to traditional portable pumps.

Main features

• Pressure range: up to 70 bar
• Two models available: ADT992 (50 bar) and ADT993 (70 bar)
• Dual-stage piston for high pressure with low operator effort
• Multi-position (tiltable head) for flexible field use
• Lever actuation for rapid pressure stabilization
• Portable: weight 1.6 kg
• Low maintenance

Detailed description
The portable pneumatic pumps ADT992 and ADT993 cover a very wide pressure range (from 95% vacuum to 50 bar for the ADT992 and up to 70 bar for the ADT993), suitable for numerous calibration and test applications. The dual-stage pre‑pressure piston provides an extended pressure range and low-effort performance. The lever pressurization system stabilizes pressure rapidly, and the fine-adjustment screw enables precise setpoints. The longitudinal layout and four operating positions improve on-site control and ergonomics.
