Accessories for This Pump
Commonly specified alongside fixed-speed Grundfos pumps. Send us your pump nameplate and we will confirm the correct part for your exact build and voltage before you order.
LiqTec Dry-Run Protection Sensor
Shuts the pump down before a dry run destroys the shaft seal — the single most common CR failure mode.
CUE Variable Frequency Drive
External VFD that converts this fixed-speed pump to constant-pressure or variable-flow control.- RPS Pressure Sensor
Discharge pressure feedback for constant-pressure booster control.
