Series description: Wilo- H/m,8,6,4 A,2,5,1,15,2,25,3 Q/m³/h Design Glandless circulation pump with threaded connection and blockingcurrent proof synchronous motor Application Potable water circulation systems in industry and building services. Ce circulateur convient seulement pour l'eau potable. Type key Example: Star-Z NOVA A C Wilo- Secondary hot water circulation pump, glandless pump Type designation with ball shut-off valve and non-return valve with ball shut-off valve, non-return valve and plug-in time switch Special features/product advantages Extremely low power consumption: 2 to 4.5 Watt due to new synchronous motor of the highest quality: with stainless steel impeller. This results in a top hygiene standard, durability and reliable protection against corrosion. Extended field of application for calcareous water: up to 2 dh Flexible service motor: Fast replacement of all common pump types Fast electrical connection by the Wilo-Connector Version A with ball shut-off valve and non-return valve Version C with ball shut-off valve, non-return valve and plug-in time switch Equipment/function Quick electrical connection with Wilo-Connector Integrated ball shut-off valve on the suction side ( A, Star-Z-NOVA C only) Integrated non-return valve on the pressure side ( A, Star- Z-NOVA C only) Blocking current-proof motor Plug-in time switch (only ) 1.8 m connecting cable with shock-proof plug (only ) Thermal insulation as standard Pump housing: Brass Impeller: Shaft: Bearing: Carbon, synthetic resin impregnated Scope of delivery Pump Thermal insulation Wilo-Connector Seals Installation and operating instructions Accessories Screwed connections Adapter fittings Technical data Fluid temperature: Potable water up to 2 dh: max. +65 C, in shortterm operation (2 h) up to +7 C Mains connection 1~23 V, 5 Hz Protection class IP 42 Nominal diameter Rp ½ Max. operating pressure 1 bar Subject to change without prior notice. www.wilo.co.uk 5 Hz EU 213-2 1 / 7
