Think System. Think Optimisation
Grundfos is able to equip any application with a complete SP system to optimise performance and energy efficiency. An SP system combines:
A high-grade stainless steel SP pump
A dedicated MS/MMS motor
An electronic motor protection (MP204) or a frequency drive (CUE)
Monitoring (GRM)
Features & Benefits
A complete SP system offers the following features and benefits:
High energy efficiency
Reliable performance over its entire life time
Time-saving installation
Easy installation
Easy operate
Pump & motor protection
The components
All components in an SP system have been designed by Grundfos to work perfectly together. In addition to the 100% high-grade stainless steel SP pump a complete system consists of the following components below:
The motor
The corrosion resistant MS and MMS submersible motors have been specially developed for the SP range to match the best efficiency point of the pumps:
• Canned type MS motors – for 4″ and 6″ pumps from 0,37 kW to 30 kW - Hermetically sealed - Available in high-grade stainless steel in two variants: EN 1.4301/AISI 304 for drinking water and EN 1.4539/AISI 904L for aggressive water, e.g. seawater • Rewindable type MMS motors – for 6″, 8″ and 10″ pumps from 5,5 kW to 250 kW - Available in high-grade stainless steel in three variants: EN 1.4301/AISI 304 for drinking water, EN 1.4401/AISI 316 for brackish water and EN 1.4539/AISI 904L for aggressive water, e.g. seawater • NEMA standard drive end on 4″, 6″ and 8″
Frequency drive (CUE)
Grundfos’ frequency drive (CUE) is designed for intelligent speed control of pumps:
• Adapts automatically to changes in the system • Ensures constant pressure, constant flow, constant water level or constant temperature • Efficient control protects pump, motor and electronics against stress and overload • Reduces life cycle cost and CO2 emission through energy-efficient operation • Soft start ensures long life and no water hammering • Easy setting via intuitive start-up guide • Easy connection to Grundfos Remote Management (GRM) and communication to SCADA systems • Radio Frequency Interference filter ensures clear signal in domestic areas
Motor protection (MP204)
The electronic motor protection MP204 is ideal where a frequency drive is not installed:
• Protects pump motors against variations in power supply • Stops the pump before dry-running to prevent damage • Performs insolation resistance test before start of the motor • Monitors parameters like temperature, overvoltage/undervoltage and power consumption • Easy to install, easy to set up and easy to operate • Easy to connect to Grundfos Remote Management (GRM) • Compatible with any SCADA system via CIU
Monitoring (GRM)
Grundfos Remote Management (GRM) offers 24 hour remote monitoring of the system:
• Cost-effective monitoring and management of pump installations • Full overview of operation, performance and trends • Live monitoring, analysis and adjustments • Monitoring of energy consumption • Reduced need for onsite inspection • Alarms and warnings as SMS/email • Notification when service is due
