SilentFlo™ Hydraulic Power Units

SilentFlo Hydraulic Power Units

With features that maximize electrical efficiency and minimize water consumption, and options for remote monitoring of pressure, temperature and fluid level, these HPUs will help reduce facility energy costs. For additional energy savings, the larger units can be equipped with a run-on-demand option that reduces electrical power and cooling water consumption when the system is not running at full capacity.

Key Product Features

Energy Efficient

New power modules and cooling circuits make this HPU up to 8% more energy efficient than previous models

Cost Efficient

Easy to install pump/motor modules add capacity at a fraction of the cost

Innovative Technology

Remote monitoring and control options available

Quiet Operation

Up to 30 dB(A) quieter than conventional HPUs
