Tender Text Phone: +234835621265 Date: 16/3/217 Product No.: 9913375 HYDRO MULTI-E 3 CRE15-4 Note! Product picture may differ from actual product GRUNDFOS Hydro Multi-E booster sets are designed for the transfer and pressure boosting of clean water in waterworks, blocks of flats, hotels, industry, hospitals, schools, etc. GRUNDFOS Hydro Multi-E booster set consists of 2 to 4 CRE pumps coupled in parallel and mounted on a common base frame provided with all the necessary fittings. Hydro Multi-E is mounted on a common base frame made of stainless steel (DIN W.-Nr. 1.431). On the suction side are fitted a suction manifold (DIN W.-Nr. 1.441 or DIN W.-Nr. 1.4571) an pressure switch mounted in on a drainable valve and an isolating valve. On the discharge side of the pumps are fitted a non-return valve, an isolating valve, a pressure gauge, two pressure transmitters mounted on a drainable valve, a diaphragm tank and a stainless steel discharge manifold (DIN W.-Nr. 1.441 or DIN W.-Nr. 1.4571). The Hydro Multi-E is fitted with an on/off-switch for the supply voltage. The Hydro Multi-E is designed for maintaining a constant pressure regardless of flow changes and fluctuation. The internal PI-controller regulates the number of running pumps and the speed of the pumps according to the required flow. The system can be operated directly on the panel of any of the pumps or via Grundfos GO (available as accessory) Besides the system features: 2 Digital outputs 2 Digital inputs (one used for dry run protection) 2 Analogue inputs (one used for discharge pressure sensor) Multi-Master functionality 2 Limit functions Set-point influence function Pipe filling function High Efficient PM motors Available communication protocols: LON Profibus Modbus SMS/GSM/GPRS GRM BACnet BACnet IP Modbus TCP PROFINET When delivered, the GRUNDFOS Hydro Multi-E booster set is factory tested and ready for operation.
