Pressure Calibration Equipment
Hydraulic High Pressure Calibration Pump
Additel 946A
OVERVIEW
The new Additel 946A Hydraulic Pressure Test Pump is a benchtop pressure pump designed to generate pressure to
15,000 psi (1,000 bar). This pump incorporates a dual-piston system which is ideal for lling large volume workload
with the hand pump and providing smooth increase and decrease of pressure with the high pressure, fine adjust
screw press. The 946A test pump incorporates an isolation valve which isolates the calibration volume from the check
valve associated with the hand pump. Because the check valve can often be a source of leaks and maintenance, the
isolation valve provides more stable measurements and reduces potential maintenance of the pump. Three hand-tight
quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need
for PTFE tape or wrenches. The Additel 946A is an ideal comparison test pump for calibrating pressure measuring
instruments such as test gauges, indicators or transducers.
Hand pump to fill large volume systems
Durable and Minimal Maintenance
Isolation valve provides stable pressures while
reducing maintenance on the hand pump check valve.
Easy-to-use
15,000 psi (1,000 bar) can be generated easily with
the dual-piston system.
Three hand-tight quick connectors
Allows easy connection and disconnection to the test
pump without the need for PTFE tape or wrenches.
Media: Mineral oil or deionized water. (Oil is default
media liquid. Pump with water as media to be
ordered as ADT946W. Pump stability is best when
used with oil. Performance may decrease when
used with water as the media.)
