For direct drive applications, Giant offers a variety of American-made couplers. These devices help transmit the force from an electric motor, gasoline engine, diesel engine, hydraulic motor or air motor directly to the crankshaft of the high pressure pump. Fabricated of steel, aluminum and plastic.

17270
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 28mm shaft of a P400 series or SP series pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17271
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 28mm shaft of a P400 series or SP series pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17272
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 28mm shaft of a P400 series or SP series pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17279
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 28mm shaft of a P400 series or SP series pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17311

17314
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 24mm shaft of a P200 series, P300 Series, P54, P55, P56, P57, P58 & P59 pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17315
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 24mm shaft of a P200 series, P300 Series, P54, P55, P56, P57, P58 & P59 pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17318
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 24mm shaft of a P200 series, P300 Series, P54, P55, P56, P57, P58 & P59 pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17319
This coupler transmits the power from the electric motor, gasoline engine, diesel engine, air motor or hydraulic motor to the 24mm shaft of a P200 series, P300 Series, P54, P55, P56, P57, P58 & P59 pump.  It directly couples the two keyed crankshafts together, so that as the driver crankshaft rotates, the pump crankshaft rotates at the same speed.
17320
