Can this deep well pump deliver substantial vertical lift from deep water reservoirs?
Lifting water from deep subterranean sources, the 4GS15-1 develops a peak dynamic head of approximately 114 m.
What water delivery volume does this deep well bore unit produce through its outlet pipe?
Clean water volume transfer is sustained by the 4GS-15-1, achieving a maximum flow rate of approximately 90 L/Min through its outlet.
How is this submersible bore pump protected against abrasive subterranean sand particulates?
Hydraulic stack longevity in abrasive well water relies on AISI 304 stainless steel casing, floating Lexan impellers, and Noryl diffusers in the 4GS 15 1, which withstands suspended sand up to 150 g/m³.
What electrical power and voltage supply must be connected to this submersible motor?
Operating the deep well assembly of the 4GS_15_1 mandates a 1.5 kW motor feed matching 220–240 V, 50 Hz, single-phase, paired with a 4OS motor with dedicated control box submerged up to 150 meters.
Does this deep well pump incorporate an integrated check valve to prevent water backflow?
Subterranean positioning for the 4GS15-1 demands a 4-inch borehole installations and vertical discharge piping of Rp 1-1/4" (32 mm), with an integrated non-return check valve stopping backflow.
