Pumps are links used to lift water to higher elevations. A pump curve describes the relation between a pump's flow rate and conditions at its inlet and outlet nodes. Five different types of pumps are supported:
The input parameters for a Pump are listed in the table below:
| Field | Description |
| Name | User-assigned pump name. |
| Start Node | Name of node on the inlet side of the pump. |
| End Node | Name of node on the outlet side of the pump. |
| Pump Curve | Name of the Pump Curve which contains the pump's operating data (to make changes to the curve, click 'Edit Curve'). Select 'Ideal pump' (or '*') for a transfer pump whose flow rate equals the inflow rate at its upstream node. |
| Initial Status | Status of the pump (ON or OFF) at the start of the simulation. |
| Startup Depth | Depth at inlet node when pump turns on (ft or m). Enter 0 if not applicable. |
| Shutoff Depth | Depth at inlet node when pump shuts off (ft or m). Enter 0 if not applicable. |
