The drive shaft is the core transmission component between the gear motor output and the pump rotor. Its plug-in engagement locks precisely to the reducer output, carrying the full torque, axial and radial load of the pump while damping vibration to prevent wear, noise and flow fluctuation. Available in cast steel (general service), hardened alloy steel (high-pressure / abrasive media) and stainless steel (chemical / food / pharmaceutical duty).

Torque-transmitting drive shaft — plug-in engagement, three coupling types.
