Ubique Systems designs oil pump and water pump test rigs that reproduce application-specific speed, back pressure, temperature and suction conditions. The system measures pump flow and pressure response at defined operating points, helping manufacturers verify fluid-delivery performance before the pump assembly reaches the vehicle.
What is the purpose of this machine?
A pump test machine validates whether an oil pump or water pump delivers the required fluid flow under the conditions expected in the application. The machine drives the pump at controlled speeds and circulates oil, coolant or another specified test fluid through a controlled circuit. It can generate defined back pressure, condition the fluid temperature, simulate negative suction head and measure the pump’s response.
The oil pump version is suited to engine lubrication, transmission lubrication, hydraulic and other fluid-delivery applications. The water pump version is suited to engine cooling, thermal management and coolant circulation. The test rig can be designed for multiple pump variants with limited fixture changeover.
Why is pump EOL testing important?
A pump may rotate correctly and still fail to deliver sufficient flow at operating pressure or temperature. Low flow, excessive flow, pressure instability, internal slip, inlet restriction, cavitation risk or wrong rotation can lead to lubrication failure, overheating or insufficient cooling. EOL pump testing measures the actual performance curve of the finished assembly and provides an objective release decision.
Typical working sequence
The pump is located in a dedicated fixture and identified by barcode. The correct recipe sets speed, temperature, pressure, suction and test duration. The drive motor rotates the pump while the circuit controls back pressure and fluid condition. Flow, pressure, temperature and input conditions are continuously measured. The software compares the values with the programmed acceptance window, stores the result and can transfer data to MES.
Typical machine features
Ubique’s first-party oil-pump and water-pump pages describe customer-specific fixtures, variable speed through an AC variable drive controlled motor, variable back pressure through a manual or servo-controlled valve, high-back-pressure flow measurement, multiple circuit lines, controlled fluid temperature, suction-head simulation, PC plus PLC software, MES transfer, barcode, variant programs and closed-loop filtration.[4][5]

Product Overview
The UBIQUE Oil Seal Lip Radial Load Tester (Model OSRL) is designed to measure the force exerted by oil seal lip/s on the mating shaft in static condition. The machine is based on the test procedure laid down in SAE J1901 Split Shaft Method.
Test Method
The tester is based on the SAE J1901 Split Shaft Method for measuring the force exerted by oil seal lip/s on the mating shaft while the seal is in a static condition.
Dedicated Mandrels and Shaft Simulation
The machine is designed to simulate shaft diameters from 15 mm to 200 mm by using suitable size-specific dedicated mandrels. Dedicated tooling can therefore be selected according to the oil seal application and shaft diameter being evaluated.
Force Measurement and Digital Display
The tester incorporates a dedicated microcontroller and digital display. The force measuring unit can be selected in Newton (N), Kilogram-force (kgf) or Newton-Pi (NΠ), as specified for the machine.
Test Data Acquisition
The machine is supplied with dedicated Windows-based PC software for online uploading of test results. Test data can be uploaded as an .xls file with a date-time stamp using Microsoft Excel.
Typical Applications
• Oil seal manufacturing and quality control
• Automotive component manufacturing
• Oil seal inspection and testing
• Testing and quality-control laboratories
• Product development and evaluation of oil seal applications
