The 30200105 Pioneer Pump is the factory OEM flywheel drive coupling for Pioneer diesel-driven pump packages. Bolted directly to the engine flywheel, the coupling transmits torque to the pump shaft through a highly flexible rubber element that absorbs the torsional vibration and firing-pulse shock loads a diesel engine produces. This protects the pump bearings, mechanical seal, and engine crankshaft while compensating for the axial, radial, and angular misalignment that develops in skid-mounted and trailer-mounted units working in the field. The plug-in design allows blind assembly between the engine and pump end and simplifies element replacement during service.
A worn coupling announces itself: rattle at idle, rubber dust inside the flywheel housing, or visible cracking in the element. Replace it at the first sign of wear and keep your dewatering, bypass, or wellpoint job on schedule.
