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 condition Suction lift up to 8m Liquid temperature ≤+90℃ Environment 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 control 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 Model DN1DN2 A B C D E F G L H1 H2 H3 PW125 3/4" 3/4" 110 136 204 46 39 49.5 165 259 72 150 245.5 PW250 1" 1" 110 136 204 40 39 49.5 165 259 72 150 245.5 PW370 1" 1" 110 136 204 40 39 49.5 165 259 72 150 245.5 PW550 1" 1" 132 160 212 50 39 41.5 190 268 84 170 285 PW750 1" 1" 132 160 212 50 39 41.5 190 268 84 170 285 Model DN1DN2 A B C D E F G L H1 H2 H3 PW125Z 3/4" 3/4" 110 136 204 46 39 49.5 165 259 72 150 261 PW250Z 1" 1" 110 136 204 40 39 49.5 165 259 72 150 261 PW370Z 1" 1" 110 136 204 40 39 49.5 165 259 72 150 261 PW550Z 1" 1" 132 160 212 50 39 41.5 190 268 84 170 293 PW750Z 1" 1" 132 160 212 50 39 41.5 190 268 84 170 293 Performance Curve Performance parameters Model Power Max.
