E-pumps - CRE, CRE Plus, SPKE, CHKE

The Grundfos E-pump delivers tremendous pumping flexibility and energy savings. Each pump automatically adjusts its speed to meet a wide range of operating conditions. The E-pump provides constant or variable flow, pressure and temperature for such applications as heating, cooling and water supply. They are also great for process operations where a 0/4 - 20 MA, 0/2 -10 V, or 1-2 Khz signal is provided by a sensor. A "PI" system controller and 5 V and 24 V sensor power are also integrated to provide a "Total Pumping System." The perfect water treatment system pump!

Integrated VFD Motors with PI Control

• The unique Grundfos micro-frequency converter adjusts motor speed to meet application-specific demand
• Flexible "performance area" (rather than fixed curve) simplifies pump selection & minimizes inventory
• Consistent performance at optimal duty points
• Energy savings resulting from automatically adjusted motor speeds
• Easy installation & operation -- pump, motor, VFD and PI are all integrated into one compact unit
• Lower RF and EMI emissions than conventional variable-frequency drive motors
• Whisper-quiet operation
• A payback and IRR (internal rate of return) PC program is available from Grundfos E-pump distributors.
