Radial Shaft Seal Testing

The Engineering group at ESP International specializes in sealing applications with a focus on radial shaft seal technology and testing. We pride ourselves on our ability to innovate and think outside of the box, developing solutions for difficult problems.

ESP Engineering is dedicated to providing the necessary attention to detail to accurately administer industry-recognized testing services. We are proud of the innovation we bring to developing unique test protocols in situations where no established procedures exist.

Leading our shaft seal test facility are a group of highly qualified degreed professionals. They are supported by innovative and talented mechanical and electrical technicians who execute tests and collect the necessary data. Collectively, our team has many years of experience in the design and execution of sophisticated shaft seal tests.

With our radial shaft seal development effort, we combine both product design and lab testing in order to bring a new product to market. Utilizing finite element and 3D cad at the beginning of a product development stage and then verifying the result through lab testing.

We offer both services together or separately as well, it all depends on your specific need.

Testing Capabilities

ESP Engineering’s advanced shaft seal test facility utilizes state-of-the-art shaft seal test machines allowing you to evaluate various seal designs for your specific application.

  • Hot Oil Testing

Our test lab can simulate a shaft seal application by running a duty cycle similar to the actual application. Modification of the sealing parameters is possible during the running of test. It’s common to run varying shaft speeds over a set period of time.

Application parameters that can be changed:

  • Shaft Speed (0-10,000 RPM)
  • Fluid Temp (Ambient – 200°C)
  • Fluid Type - Shaft Runout (0-0.5mm)
  • Shaft to Bore Misalignment (0-5mm)
  • Oil Fill Level
  • Oil Pressure (0-200 bar)
  • Dust & Slurry

This is a bolt-on option to our hot oil seal test machines. It allows you to introduce media to the excluding features of the seal. Mixtures of ISO 12103-1 test dust with bentonite clay and water are standard but it is possible to run any media such as belt dust, volcanic ash or water.The sump and dust chamber are monitored daily for ingress of debris or failure of the seal. Comparison testing of seal designs is common with this type of test.

  • Seal Power Consumption

All shaft seals create some friction on the rotating shaft. That friction results in some power loss to the vehicle and in situations where maintaining vehicle power is important the selection of shaft seal becomes important as well. Our seal power consumption test equipment can determine the amount of power drawn from various seal designs. Giving you the proper information you need when selecting a shaft seal design.
