Customizable Submersible Axial Flow Pump with High Cavitation Performance

For a project that needs 3 cubic meters per second or so moving against maybe 6-7 meters head, most buyers just go with the standard configuration because the lead time is shorter, but you can actually customize the impeller diameter and motor power within reason — we've done this for flood control ops where cavitation was killing smaller pumps.

At 495 rpm with a 1000mm outlet, capacity runs 2.5 to 3.1 m³/s, and that's at 84.9% peak efficiency if your medium stays under 43°C, the double cartridge seal and IP68 rating mean it's pretty much fine submerged for years, but the 3400 kg beast definetly takes planning for insallation, especially in wellbores down to 1350mm where clearance gets tight.

Works best for large-scale drainage or irrigation, not for anything with solids over 50 ppm (the submersible motor doesn't like debris), and while the HT250 casting holds up, the stainless option (ZG07Cr19Ni10) is better for aggressive water — both ship with COA but confirm lead time, usually 20 days or so depending on motor votage (380V or 6KV we stock, 10KV takes roughly 4 weeks).

So impeller's 850mm diameter and thrust bearings handle high axial loads you'd see in deep sumps, but don't expect this to handle variable speed well at very low flows — a concrete detail is the motor cable entry has a secondary seal that needs checking after the first year, and we've had buyers for fish farm recirculation too, though they often need a modified inlet screen.

Just order per unit with at least 2 weeks notice, 132 to 260 kW motor range depending on your actual duty point.
