Over the years, we have had numerous requests from customers looking to pump unusual fluids. Our challenge was to develop a reasonable low-cost method of providing our customers with a viable solution.
By utilizing commercially available components of a hydraulic system, our team has successfully solved for a variety of common pumping challenges. These solutions are most effective and satisfy a majority of unusual applications.
Here is an application where such a system played an essential role in meeting a customer's special requirement.
The challenge was to provide a pumping system that would test brake valves. The requirements include that the system pump's brake fluid temperatures range from -50°F to 250°F. Along with this, the brake fluid viscosity varied dramatically from very high to very low with the temperature variance.
To further complicate the solution, the brake fluid seal compatibility required ammonia-treated seals, which would not work well with conventional commercially available hydraulic components.
This system needs to test the brake valves at 1000 PSI and it was preferred that the system offer pressure compensation at the special condition output.
Using a conventional pressure compensated hydraulic pump to drive the master cylinder allows the slave cylinder/pump to react with pressure compensation.
This type of system can solve directly for your special fluid and/or temperature challenges.
