The CRE-DP is a vertical multistage HVAC pump with its drive, controls and a differential pressure sensor mounted and configured at the factory. Proportional differential pressure control lowers the setpoint at low flow and raises it at high flow, which simulates a remote sensor without running wire to the far end of the system; constant differential pressure, external setpoint and constant curve modes are also built in.
Pump curve data is loaded into the MLE motor, so the pump arrives ready to run. A Grundfos GO app or R100 remote sets it up; CIM and CIU modules connect it to the building management system.
Included: CRE pump with MLE motor and factory-mounted differential pressure sensor (NPT builds include a hollow-stem drain plug; flanged builds include a sensor extension kit).
Ships: by LTL freight.
Needed to run: the supply shown on the build, isolation valves, and the system piping (2 in NPT or ANSI flanges per the Connection option).

From the Grundfos 2026 Industrial price book. The performance range chart is in the images; send us the flow and head and we will confirm the model on its curve.
| Duty point | Pick the model whose curve covers the design flow and head; DP sensor range rises with pump head. |
| Service | Closed HVAC loops: chilled water, hot water, district systems, cooling towers. |
Chilled water and hot water distribution, district heating and cooling, and cooling tower loops.
