From Bombas Hasa to we present the new SIENA INOX Series, a multicellular submersible electric pump with all components in contact with water made of AISI 304 stainless steel, ideal for domestic installations and open wells. In addition to being made of 100% stainless steel, which prevents corrosion, extending the durability of the pump, it has NBR O-rings and a double silicon/silicon + Ceramic/Carbon mechanical seal that guarantees better sealing and greater motor protection. Single-phase models are supplied with level switch and Controlbox with ON/OFF switch, built-in capacitor and circuit breaker. Optionally, it can be supplied with a sacrificial anode to absorb galvanic currents (wear by electrolysis).
