Hydrostatic Drive

Hydrostatic drives are common in a variety of off-road equipment including large industrial lawn care equipment. Each drive consists of a hydraulic pump that provides a flow to an integral hydraulic motor used to propel the equipment. Output speed/power of the drive is controlled by a swash plate.

Our system is fully capable of simulating all real-world conditions the part will encounter, including full load pressure, torque and speed. It also controls the swash plate angle to allow testing at different pump displacements.

Specifications include a 25 Hp 3600 RPM input drive (electric motor) and an output dynamometer (hydraulic motor) capable of generating up to 4,500 ft-lbs a 0.5 in-lbs accuracy. The versatility of the system allows it to be configured both as a hydraulic pump and a motor test stand.

"I originally sourced another company for our equipment and yet another NI alliance member for an upgrade, dissatisfied with the performance and in an emergency need, I contacted WTI on a Friday afternoon. The next day, a Saturday, an engineer was on-site."
