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.
