2-piston hydraulic pump ADT 928A

manualhandaluminum

Presentation The ADDITEL ADT 928A hydraulic pump is a manual pump designed to generate and control pressure up to 1000 bar (15,000 psi). It features a double-piston system to pressurize large-volume systems while providing fine pressure adjustment both during increase and decrease.

Main features

• Double-piston system: rapid filling of large volumes and fine pressure adjustment.
• Isolating valve system for the calibration volume: reduces leakage and improves generated pressure stability.
• Two manual-clamp connectors: quick connection of gauges and instruments without tools or PTFE tape.
• Fluid compatibility by model: mineral oils, distilled water (option ADT 928A-W) and Skydrol (option ADT928A-AC).
• Intended for calibration of transmitters and pressure gauges, suitable for field or laboratory use.

Models

• ADT928A — Hydraulic pump (oil), range -0.95 to 1000 bar.
• ADT928A-W — Hydraulic pump (distilled water), range -0.95 to 1000 bar.
• ADT928A-AC — Hydraulic pump (Skydrol), range -0.95 to 1000 bar.
