DESCRIPTION_LONG
Tender text
Highly efficient, non-self-priming high-pressure multistage centrifugal pump in horizontal design, equipped with electronically controlled EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2. The pump is suitable for water supply, water distribution and pressure boosting, industrial recirculation systems, process water, closed cooling circuits and heating. It can also be used in washing systems as well as for irrigation. Control modes: *Constant speed n-c: manually with green button or via external signals *Constant pressure p-c, constant differential pressure ∆p-c, variable pressure p-v, variable differential pressure ∆p-v: pressure control with sensor, setpoint adjustment with green button or by means of external signals *PID control: other constant control variables (temperature, volume flow, pressure....) with sensor, setpoint adjustment with green button, by means of external signals The electronic module provides various functions: *Max. pressure limit detection *Min. pressure limit detection *Lack of water detection by suction sensor *Zero-flow test (open loop) *No-Flow Stop (closed loop) *Dry-running detection *Volume flow calculation by using differential pressure sensor *Pump kick *Error and warning codes *Overload protection *Plug-in position for Wilo CIF modules PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to the building automation *Green LED indicates the pump status *Blue LED indicates that the pump is influenced externally via an interface Analogue input: *IN (AI 1): Input sensor signal 4-20 mA, 0-10 V, 0-20 mA or 2-10 V *IN (AI 2): Input setpoint 0-20 mA, 0-10 V, 4-20 mA or 2-10 V Digital input IN (DI 1): *Extern OFF *Lack of water detection by binary input Dual pump management (2 x single pumps) *Main/standby operation *Pump cycling main/standby operation after 24 hours or automatic fault-actuated switchover *Wired connection via Wilo Net Special features/product advantages *IE5 EC motor and integrated frequency converter in combination with Medana CH high efficiency hydraulics *2” coloured LCD display, Wilo Green Button Technology and soft button with return function. The pump menu is clearly structured and enables a comfortable setting of the pump. *Analogue and digital interface as well as CIF module *Intelligent with various control modes, integrated dual pump management *Efficiency-optimised, laser-welded 2D/3D high-efficiency hydraulics (flow and degassing optimised) *Corrosion-resistant impellers, guide vanes and stage housings *Flow and degassing-optimised hydraulics *Flow and NPSH-optimised pump housing *Easy-maintenance design *Drinking water approval for pumps with parts that come in contact with the fluid made of stainless steel (EPDM version) Scope of delivery *Medana CH3-LE multistage centrifugal pump *Installation and operating instructions Design notes *Optional plug-in CIF-Modules PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to the building automation *Optional connection M12 RJ45 CIF Ethernet *Sensors are available as accessories: differential pressure kit 4 – 20mA and relative pressure kit 4 – 20mA
