Differential Pressure / Oil filter test stand (ISO 4548-1)

The test stand is mainly used for testing the performance of hydraulic filters and filter elements according to the ISO 4548-1. The scope of the testing is to measure the differential pressure across the filter housing or filter element as a function of the volumetric flow rate and the viscosity.

The test stand is automatically controlled by a computer which saves the measured data in chronological order; the flow chart and all the test parameters can be displayed on the screen. Data handling and generation of reports according to the standard ISO 4548-1 are included.

Applicable tests

The test stand is designed as an Oil Filter Test Stand acc. to ISO 4548-1 as a part of the filter manufacturing and quality monitoring cente

Following tests can be performed with this test stand:

  • Differential pressure characteristics acc. to ISO 4548-1
  • Flow rate ramp
  • Differential pressure characteristics of bypass valve
  • Opening pressure of bypass valve
  • Leakage volume of bypass valve

This test stand can be also configured and quoted according to your individual specifications.
