Motor
This pump has a hollow shaft. It fits straight onto the shaft of a hollow-shaft motor or engine, so there is no flange or coupling between them. You need a hollow-shaft motor of at least 0.16 kW.
Flange
None needed: the pump fits straight onto a hollow-shaft motor.
Coupling
None needed: the pump fits straight onto a hollow-shaft motor.
