Blackmer ProVane Hydrodynamic Journal Bearing Improves Terminal Efficiency
Blackmer’s ProVane Motor Speed Vane Pumps are ideal for various applications in the liquid terminals industry. The ProVane pump’s innovative Hydrodynamic Journal Bearing design reduces shaft/bearing contact, minimizing friction and resulting in higher mechanical efficiency and smart energy cost savings for Liquid Terminal operators.

The Hydrodynamic Journal Bearing — a unique fluid boundary forming principal — eliminates shaft-to-bearing contact within the ProVane pump by hydroplaning above the bearing surface on a cushion of liquid. In this hydrodynamic condition there is no metal-to-metal contact or wear and bearing life can be indefinite. ProVane pumps are engineered to achieve hydrodynamic mode (full film operation — the point offering the lowest bearing friction and least wear) faster than any other pump in their class to preserve bearing life. It also maintains optimum bearing characteristics even under the wide range of operating conditions of terminal production, process and blending applications.
The Blackmer ProVane pump does not require a gear reducer, so it offers a compact profile, upfront equipment, installation and energy cost savings, as well as the smaller footprint of a complete pumping unit. The vane technology principles of the ProVane pump ensure superior performance even after significant in-service time, eliminating efficiency-robbing “slip” that may occur with other pump technologies. The ProVane pump delivers performance reliability, reduced preventative maintenance and operating speeds up to 3600 rpm with capacities from 6 to 100 U.S. gallons (379 liters) per minute, in sizes ranging from ¾" to 2". Designed for continuous duty process operations transferring low and medium viscosity liquids, it features self-priming, low shear and superior line stripping results through exceptional suction and lifting capabilities.
