Liquid / Liquid and Liquid / Gas media separators

P5521 Liquid to Liquid separator. 10000 psi / 700 bar.
P5522 Liquid to Liquid separator. 8000 psi / 500 bar.
P5523 Liquid to Gas separator. 3500 psi / 220 bar.

The Separator is an efficient means of transmitting pressure from one liquid to another via a flexible baffle
suitable for use with oxygen clean applications. Connected directly to the test station of an oil operated
deadweight or comparison pump the Separator provides a barrier between the oil and the instrument being
calibrated.

Model  Description 
P5521  Liquid to Liquid separator. 10000 psi / 700 bar.
P5522  Liquid to Liquid separator. 8000 psi / 500 bar.
P5523  Liquid to Gas separator. 3500 psi / 220 bar.

Liquid to Liquid Separators

Model 5521 Pressure range 0 to 10,000 psi (700 bar)

Model 5522 Pressure range 0 to 7,000 psi (480 bar) for Skydrol and other aggresive fluids

These liquid-to-liquid separators connect directly to the test port of a hydraulic deadweight tester or
comparison test pump. A flexible diaphragm separates the fluids, protecting the calibrator from
contamination and allows calibration of the device in its specific working fluid.

Liquid to Gas Separator.

Model 5523 Pressure range 0 to 3,000 psi (210 bar)
For high pressure pneumatic calibrations this unit interfaces with hydraulic deadweight testers
providing a rateless liquid-to gas separation.
Driven by a pneumatic pressure source (nitrogen bottle) and controlled by needle valves, high
pressure gas is balanced against the liquid in a hydraulic deadweight tester through a series of
fluid traps.
* Note---since fluid mist may be transferred during operation we do not recommend this device for
oxygensafe instruments using an oil operated deadweight tester.
