Don’t be confused! Spot the difference
Helpful hint: think function, not form Head, flow, speed, logic
Reality vs. Model

Pump Choices:1. Pump Location: submerged or dry2. Displacement type: positive or centrifugal (or axial)3. Motor speed: variable or fixed4. Orientation: horizontal or vertical5. Appurtenances: grinders, screens

Pump Choices:1. Head Type: Dynamic or Static2. Rating Type: Node depth or wet well volume3. Motor Type: Variable or fixed speed4. Logic: Simple or remote/complex flow control
Pumps: Model
4 Basic Types
Examples: Model
Type Based On CurveTypically
Location Speed
1 Wet Well Volume Incremental Off-Line Fixed
2 Inlet Node Depth Incremental In-Line Fixed
3 Outlet - Inlet Head Continuous In-Line Fixed
4 Inlet Node Depth Continuous In-Line Variable
Logic, per time step
Notes No start/stop levels A value of 0 can be used in the curve Least popular pump option

Volume Curve Pump Flow
Logic, per time step
Notes No start/stop levels A value of 0 can be used in the curve During low flow the pump will automatically reduce flow
