Circulation pump LPA 40-16-750 for water heating systems

Flanged circulation pump EuroAqua LPA 40-16-750. Designed for hot water circulation in domestic and industrial heating systems. Used in systems with expansion tanks, providing the required water pressure in heating and communication pipes. Reliable flange connection has high strength and is widely used in small boiler houses or thermal power plants. The pump body is made of cast iron, this material can withstand heavy loads and is resistant to mechanical damage. The electric motor has two types of cooling: pumped liquid and passive air through the outer casing. Simple and reliable design of the pump will ensure uninterrupted operation for a long time. Technical specifications: maximum flow rate: 15 m3/hour (250 l/min.) maximum head: 16 m Power consumption: 750 W connection type: flange DN40 temperature of pumped liquid: up to +110 °C maximum ambient temperature: up to +40 °C maximum pressure in the hydraulic system - 10 bar weight: 15 kg Limitation working fluid: clean, non-viscous, non-aggressive liquids, free of solid particles or fibres, similar to water in density and chemical activity total liquid hardness, no more than 700 µg-eq/kg iron compound content, no more than 500 mcg/kg dissolved oxygen content, no more than 50 μg/kg petroleum product content, no more than 1 mg/kg pH value 7.0 - 9.5 to avoid cavitation noise, the suction pressure should be at least 1.5 m of water column at a temperature of +90 °C Design characteristics monoblock horizontal with one impeller cast iron pump chamber body working wheel - centrifugal, closed type, made of composite materials radial plain bearings: ceramics/graphite Engine asynchronous two-pole with squirrel-cage "wet" rotor engine cooling by pumped liquid IP44 protection rating insulation class F supply voltage: 220 V, 50 Hz operating mode: long-term
