MOTORS PUMPS GEARBOXES VALVES CONTROLS NAHI, LLC - MAIN OFFICE : PROVIDING CUSTOMER DRIVEN SOLUTIONS - Features of the pump –Hard on Hard Running Surfaces. –Hydrodynamic Bearing Design. –Cylinder Bearing Design This design uses a cylinder bearing to directly absorb the load created by the rotating group. This allows for a smaller shaft and smaller shaft bearings

MOTORS PUMPS GEARBOXES VALVES CONTROLS NAHI, LLC - MAIN OFFICE : PROVIDING CUSTOMER DRIVEN SOLUTIONS - What is Hard on Hard? Two equally hardened surfaces running opposed to each other or valve plate to cylinder barrel. Is this unique? Yes. As most competitors choose to run soft surfaces against hard surface, i.e. bronze and hardened steel. Why does the competition do it that way? Ease of machining and cost.
