Applications Fields The self-priming peripheral pump is suitable for transferring water without abrasive particles or other liquid whose properties are similar to water. It’s widely used in household water supply, well water pumping, tap water pressure, water tower's supply, solar or hot water systems pressure, etc. Operating co
ndition Suction lift up to 8m Liquid temperature ≤+90℃ Enviro
nment temperature ≤ +40℃ Max. working pressure: 5bar Features and advantagesA self-priming peripheral pump for both hot and cold water. Advanced structure with lower noise. Intelligent co
ntrol by both flow sensor and pressure sensor, which is convenient.Materials Pump body: Cast iron with stainless steel insert Motor casing: Aluminum Impeller: Brass Shaft: Welded by SUS304 and Cs45# Mechanical seal: Ceramic/Graphite/NBR Copper winding Section and sizes
