Self-priming pump EHsp Series

waterwith asynchronous motorimpeller

Evolving from the technology of the horizontal multistage pump EH, EHsp features a design innovation of a special elastic valve system allowing air, present in the system, to escape - suction height up to 7 meters in less than 5 minutes. During start, this elastic valve, which is located at the first stage, opens to allow air to escape out of the system and water to enter the pump. As soon as the pressure arrives at a certain point, the valve closes, and the pump reaches the required performance. This makes the EHsp the only stainless steel AISI304 self-priming horizontal multistage pump in the market. ■ Compact close coupled design, robust and corrosion resistant ■ WRAS and ACS approved ■ Max suction lift capacity up to 7 m in less than 5 min ■ Superior efficiency and performances ■ Flexible application base plate ■ Floating neck ring in PPS ■ Heavy duty oversize motor shaft ■ Impellers and diffusers are made of stainless steel in order to achieve durability ■ Easy maintenance ■ Mechanical seal Type E0 = carbon/ceramic/EPDM ■ Connections: Rp threaded for inlet and outlet ■ Maximum ambient temperature: 40 °C ■ The hydraulic characteristics are guaranteed, according to ISO standard 9906:2012, grade 3B ■ Single-phase ■ Three-phase motor efficiency class IE3 ■ Asynchronous, TEFC (totally enclosed, fan-cooled) ■ 2 pole ■ IP55 protection motor, insulation class F
