Franklin Electric E-Tech EHsp Horizontal Self-Priming Multistage pump is WRAS approved and 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.
