What maximum delivery flow does this bore pump generate across its discharge outlet?
Water volume delivery from subterranean aquifers reaches a maximum flow rate of approximately 250 L/Min with the 12GS11-3.
Does this borehole pump feature specialized metallurgy and floating impellers for sand defense?
Constructed from premium AISI 304 stainless steel casing, floating Lexan impellers, and Noryl diffusers, the 12GS-11-3 resists mineral corrosion and particulate erosion while managing suspended sand up to 150 g/m³ in its 7 stages.
What power supply voltage and motor current are needed for this deep well pump?
Driving the submersible wet end of the 12GS 11 3 necessitates a 1.1 kW connection on 380–415 V, 50 Hz, three-phase, driven by a 4OS motor submerged up to 150 meters.
Does this borehole pump include an integrated check valve to prevent reverse flow backflow?
Deep well deployment of the 12GS_11_3 necessitates a 4-inch borehole installations, operating submerged up to 150 meters with a built-in integrated non-return check valve to eliminate backflow.
