The crankshaft for the Bean Pump W11 is a high-strength, precision-machined rotating component that translates rotary drive motion into the reciprocating movement required to operate the pump’s plungers. Built specifically for the W11 model of Bean reciprocating pumps, this crankshaft is engineered to meet the rigorous demands of continuous-duty applications such as oilfield chemical injection, fluid transfer, pressure washing, and industrial pumping systems.

Manufactured from forged alloy steel and heat-treated for added strength and fatigue resistance, the W11 crankshaft ensures smooth operation, reduced vibration, and long service life. It is a direct-fit replacement for OEM or compatible aftermarket W11 pump assemblies.
