ProVane's Highly Efficient Hydrodynamic Journal Bearing

Blackmer's Hydrodynamic Journal Bearing is a performance-enhancing
design feature that significantly improves overall pump efficiency, reliability and extends bearing life. With this design, the pump shaft rides on a fluid boundary during load conditions to eliminate shaft-to-bearing contact, friction and wear.

Since there is no metal-to-metal contact or wear in this hydrodynamic condition, bearing life can be indefinite. Motor speed vane pumps are engineered to achieve hydrodynamic mode (full film operation – the point offering the lowest bearing friction and the least wear) faster than any other pump in its class to preserve bearing life. These pumps also maintain optimum bearing characteristics even under a wide range of operating conditions.

Reduced shaft-to-bearing contact minimizes friction, lowers power loss, and improves reliability and bearing life, resulting in higher mechanical efficiency and smart energy cost savings.
