Additel 946A Hydraulic High Pressure Calibration Pump
Generates pressure to 15,000 psi (1,000 bar)
Dual-piston system: hand pump fills large volumes, fine-adjust screw press sets pressure smoothly
Isolation valve separates the calibration volume from the hand pump check valve for stable readings and less maintenance
Three hand-tight quick connectors, no PTFE tape or wrenches needed
Overview
The Additel 946A is a benchtop comparison test pump for calibrating gauges, indicators, and transducers to 15,000 psi. The dual-piston design pairs a hand pump for filling large-volume workloads with a fine-adjust screw press for smooth pressure changes, and the isolation valve keeps the check valve, a common source of leaks, out of the measurement path. Three quick connectors make hooking up the reference and units under test fast. A water-service version (946AW) is available.
Available configurations. Process Connection: 1/4 BSP, 1/2 BSP, M20x1.5, 1/4 NPT, 1/2 NPT. Configuration: Pump only, Set (with accessories).
Base model ADT946AW. Each configuration has its own Additel part number, shown as the SKU on your order.
