Product details
The technical sheet lists 1,485 r/min input-shaft speed while the pump-speed columns cover several reductions. For this selection, 133 r/min is the pump speed; the input speed must not be substituted into that field. The required drive and reduction arrangement should be confirmed as one assembly.
Changing plunger diameter or pump speed changes the available pressure, delivery and required power. The 31 kW figure is the power stated in the performance table, not a verified motor nameplate rating. The selected pressure and flow must be reviewed with liquid properties, continuous-duty requirements and the pressure-control package.
The official HS3Z80 product listing illustrates an assembled pump and motor package for a process application. That image establishes the series arrangement, not the exact plunger diameter or gear ratio pictured. Confirm inlet supply, wetted components, pressure-rated pipework, relief provisions and the complete assembly drawing for the specified duty.
