Product Details

The Fluid Separator provides the flexibility to calibrate hydraulic instruments using either a pneumatic (gas) input pressure source or a hydraulic input pressure source.

The Fluid Separator transmits input test pressure to the output end across an elastomeric membrane. The input end of the fluid separator can be connected to a pneumatic pressure source, or it can be filled with fluid and connected to hydraulic pressure source. The output end of the fluid separator is filled with hydraulic fluid compatible with the device under test.

Available Configurations:
  • 3734-401-001 Stand-Alone Fluid Separator Assembly in Aluminum (shown on left)
  • 3734-402-001 Stand-Alone Fluid Separator Assembly in Stainless Steel
  • 534-2 Fluid Separator Assembly for Installation in Aluminum
  • 534-2SS Fluid Separator Assembly for Installation in Stainless Steel (shown on right)

The fluid separator operation can be configured for Pneumatic Input to Liquid Output or Liquid Input to Liquid Output.
