الوصف

Design Electronically controlled glanded single pump in close-coupled design with flange connection and automatic power adjustment. Application The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems. Equipment/function Operating modes - Δp-c for constant differential pressure - Δp-v for variable differential pressure - PID-Control - Constant speed (n=constant) Manual operation level - Green button and display Manual functions - Differential pressure setpoint setting - Setting the speed (manual control mode) - Setting the operating mode - Setting the pump ON/OFF - Configuration of all operating parameters - Fault acknowledgement External control functions - 1x “Overriding Off” control input - 1x “External pump alternation” control input (effective only in twin-head pump operation) - 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) and remote setpoint adjustment - 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal from pressure sensor Signal and display functions - Collective fault signal SSM - Collective run signal SBM Data exchange - Infrared interface for wireless data exchange with IR-Stick - Plug-in position for Wilo IF-Modules (Modbus, BACnet, CAN, PLR, LON) for connection to building automation - Interface to dual-pump communication Safety functions - Full motor protection with integrated trip electronics - Access disable Dual-pump management (2 x single pump; Y-piece application only) - Main/standby operation (automatic fault-actuated switchover) - Pump alternation main/standby operation after 24 hours - Parallel operation - Parallel operation (efficiency-optimised peak load activation and deactivation) Technical data - Permissible temperature range of -20 °C to +140 °C - Minimum efficiency index (MEI) ≥ 0.4 - Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended. - Mains connection - 3~440 V -5% +10%, 50/60 Hz - 3~400 V ±10%, 50/60 Hz - 3~380 V -5% +10%, 50/60 Hz - Compliance with electromagnetic compatibility without additional measures: - Interference emission for residential environment according to EN 61800-3:2018 - Interference immunity for industrial environments according to EN 61800-3:2018 - IP55 rating - Nominal diameter DN 32 to DN 150 - Max. operating pressure 16 bar up to +120 °C, 13 bar up to +140 °C Materials - Pump housing and lantern: EN-GJL-250 - Impeller - Standard version: EN-GJL-200 - Special version: Bronze CuSn 10 - Special version: Stainless steel 1.4408 - Shaft: 1.4122 - Mechanical seal: AQEGG; other mechanical seals on request Scope of delivery - Pump - Installation and operating instructions
