Grundfos Compact-E

Grundfos Compact-E System is designed with two to four numbers of Grundfos Horizontal centrifugal multi-stage CM pumps operating in parallel via Grundfos R-series variable speed drive installed at the panel. The constant pressure boosting is able to supply water to household, dwellings, office buildings, hotels, hospitals, departmental stores and manufacturing plants.

Features and Benefits

• Constant pressure for optimum comfort and energy savings
• Simple and user friendly operation
• Lead lag and timer change over feature to ensure equal operation of pumps
• Automatuc changeover in the event of failure of one pump to prevent interruption of water supply
• High quality components for longer lasting operation
• Motor protection to minimize failure of the motor and pumps from external fault

Standard protections

• Earth leakage protection from mains
• Protection via Groundfos R-series VSD for motor and pump protection such as over-current, over-voltage, motor overload, under voltage during operation, ground fault, high pressure limit, low pressure limit, sensor fault and dry run protection.
