GRUNDFOS Grundfos Compact Lifting Station Multilift – 97901037

MSS.11.1.2 Floodable sewage lifting unit with two adjustable inlet heights of 180 and 250 mm, and 5 further inlets on the tank sides in DN 50 and DN 100, ready for installation with a submersible motor pump. Collection tank with and optionally without compact non-return valve, microprocessor control with LED display including mains cable and plug, free-flow impeller. Collection tank: Impact and break-resistant, made of polyethylene, rot-proof, gas and odor tight. Special tank base with gradient to minimize residual water volume and deposits, total volume 44 l. Pressure outlet: Composite flange transition piece consisting of flange 80 with pipe stub DN 100 and elastic connector DN 100, as well as 2 pipe clamps including all screws and seals for buoyancy protection, connection of inlet and pressure pipes in DN 100. Pump: Vertical, single-stage and floodable, protection class IP68. Compact design with maintenance-free mechanical seal and oil barrier chamber with oil bath of physiologically harmless special oil. Motor with built-in winding protection contacts. Control: Non-contact, piezoresistive pressure sensor as plug-in module in the control system, electronically monitored, millimeter-accurate level display, blockage and jam-proof, as there are no moving parts in the wastewater, moisture separator in the surge pipe head, and maintenance-friendly large-dimensioned tank screw connection. Fully electronic, pre-configured control unit for controlling and monitoring a submersible motor pump, operation via push buttons with motor protection relay, control board with LED for status indication. Additional connection terminal for an external float switch. Real-time level measurement, individual operation and individual fault messages, high water fault message, as well as additional inputs for external level switches, additional inputs for alternative level sensors such as float switches, ultrasonic sensors and hydrostatic pressure sensors, 0-5 V and 4-20 mA, wall mounting of the control without opening the control unit. Wall-mounted unit with ISO housing IP56. - Optical indication of operation and fault, high water, overtemperature, mains fault and sensor fault, phase sequence fault (3~400 V only) - Setting of switch-on height via selector switch - Operating switch H-0-A - Acoustic signal (buzzer) for fault - Fault acknowledgment button - Alarm acknowledgment (manual/automatic) - Error message - Anti-blockage function through automatic test run after 24h downtime - Pump switch-on via pressure sensor - Temperature monitoring for pumps with winding temperature sensors - Battery buffer for mains-independent alarming (see accessories) - Interface for software update - Start delay in case of surging water - Run time monitoring and dry running protection - Interface for PC tool for service and extended parametrization function Technical data: Pump speed on which pump data are based: 2760 1/min Nominal flow rate: 5.5 l/s Maximum flow rate: 8.61 l/s Nominal head: 4.1 m Impeller type: VORTEX Maximum particle size: 40 mm Approvals: CE,EAC,CN ROHS,MORO,UKCA,SEPRO Approved according to CE (Yes/No): yes EN number for LGA approval: yes Non-return valve type: Flap valve Materials: Pump housing: Composite Tank: PLASTIC Tank: LDPE Seal: NBR Installation: Ambient temperature: 0 .. 40 Celsius Outlet connection type: DIN Size of pressure connection: DN 80 Nominal pressure stage: PN 6 Pumped liquid: Medium temperature range: 0 .. 40 Celsius Medium temp. at data acquisition: 20 Celsius Density: 998.2 kg/m3 Electrical data: Power consumption P1: 1.7 kW Motor rated power P2: 1.1 kW Mains frequency: 50 Hz Rated voltage: 1 x 230 V Voltage tolerance: +10/-6 % Max starts per hour: 60 Rated current: 8 A Cos phi - Power factor: 0.95 Operating capacitor size: 20 µF Motor poles: 2 Start-up method: Direct Protection class (according to IEC 34-5): IP68 Insulation class (IEC 85): F Ex-protection standard: KLIXON Cable length: 1.5 m Power plug: SCHUKO Control type: Control cabinet type: LC220 Tank: Total volume of tank(s): 44 l Actual total volume of collection tank with 180 mm inlet: 20 l Actual total volume of collection tank with 250 mm inlet: 28 l Other: Net weight: 27.4 kg Gross weight: 38.1 kg Danish VVS No.: 154030011 Norwegian NRF No.: 9045302 Country of origin: DE Customs tariff No.: 84137021 Approvals: WEEE
