The B Series is eBORA's high-volume range, built for sites where the priority is moving large quantities of dirty water quickly and continuing to do so with solids in suspension. Six models span 245 to 3,350 m³/hr, and every one self-primes to 8.5 m, so the pump can sit above the water it is clearing rather than in it.
Maximum Flow Rate
| Model | Capacity | Total Head | Solids Handling | Self-Priming Lift | Impeller Diameter | Pump Speed | Inlet | Outlet |
|---|---|---|---|---|---|---|---|---|
| B100 | 245 m³/hr | 45 m | 44 mm | 8.5 m | 254 mm | 2200 rpm | 100 mm | 100 mm |
| B150 | 520 m³/hr | 60 m | 74 mm | 8.5 m | 300 mm | 2200 rpm | 150 mm | 150 mm |
| B200 | 845 m³/hr | 52 m | 74 mm | 8.5 m | 320 mm | 2200 rpm | 200 mm | 200 mm |
| B300 | 1,360 m³/hr | 57 m | 94 mm | 8.5 m | 362 mm | 1800 rpm | 300 mm | 300 mm |
| B400 | 2,218 m³/hr | 42 m | 124 mm | 8.5 m | 500 mm | 1200 rpm | 450 mm | 400 mm |
| B500 | 3,350 m³/hr | 49 m | 79 mm | 8.5 m | 610 mm | 1100 rpm | 500 mm | 450 mm |
Excavations, foundations and basement works accumulate groundwater and rainfall carrying sand, gravel and site debris. The B Series handles solids from 44 mm on the B100 up to 124 mm on the B400 without a separate strainer stage, which keeps a pump running through the conditions that block clean-water units. Self-priming to 8.5 m means the unit can be positioned at the excavation edge rather than lowered into it.
Pit dewatering demands sustained flow against modest head, and the water is rarely clean. The B300 at 1,360 m³/hr and B400 at 2,218 m³/hr sit in the range most pit and haul-road applications call for, while the B500 reaches 3,350 m³/hr for main sump duty. Abrasive slurry accelerates wear on any centrifugal pump, so impeller access and replaceable wear parts matter more than peak efficiency.
Storm drainage, sewer bypass and treatment-works overflow all involve intermittent, unpredictable loading. Automatic self-priming allows unattended restart after the suction line drains, which is the usual failure point in bypass installations. Sewage-impeller options are available for stringy sewage, fibrous material and organics where a standard solids impeller will rag up.
Emergency work is defined by deployment speed and tolerance for whatever the water is carrying. Diesel-driven B Series units on wheeled or skid chassis can be positioned and primed without external vacuum equipment, and the larger models clear standing water at rates that make a difference within a shift rather than a week.
Select on flow first, then confirm the head. The B Series operates across a relatively narrow head band — 42 to 60 m — so if your duty point needs more than about 60 m of total head, the K or L Series is the correct range regardless of the flow you need.
Note that the highest-flow model is not the highest solids-handling model. The B500 delivers the most water at 3,350 m³/hr but passes 79 mm solids, while the B400 moves 2,218 m³/hr and passes 124 mm. If your water carries coarse material, the B400 is the more capable pump despite the lower rating.
Every model self-primes to 8.5 m, so suction lift is not a differentiator within the range. What changes with model size is port diameter — 100 mm on the B100 through 500 mm inlet on the B500 — which must be matched to your pipework to avoid throttling the pump at the connection.
Across all three series eBORA covers flows to 3,350 m³/hr and total heads to 295 m. The B Series spans 6 models, reaching 3,350 m³/hr and 60 m of total head, handling solids up to 124 mm. Every model self-primes to 8.5 m.
Tell us the duty — flow, total head and site conditions — and our team will size it and come back with a quotation. If you are not sure which model fits, describe the application and we will work it out.
The B500 is the highest-flow model at 3,350 m³/hr against 49 m of total head, with a 500 mm inlet and 450 mm outlet. It handles solids up to 79 mm.
Yes. Standard solids handling ranges from 44 mm on the B100 to 124 mm on the B400. Sewage-impeller options are available for stringy sewage, fibrous material, organics and contaminated site water where a standard solids impeller is insufficient.
All six models self-prime to 8.5 m. Priming is automatic, so the pump does not need an external vacuum pump or a foot valve to restart after the suction line drains.
Diesel engines from CAT, Perkins, Deutz, Cummins or Yanmar, or electric motors from WEG, ABB or Siemens. Chassis options include skid-mounted, sound-attenuated enclosure, wheeled site chassis and static installation.
Applications this range is recommended for, and the reason on the published numbers.
The default range for construction. Six models from 245 to 3,350 m³/hr with solids handling to 124 mm. The B400 is worth noting specifically: it passes larger solids (124 mm) than the higher-flow B500 (79 mm), so it is often the better choice in coarse ground.
Construction pumpingOpen-pit dewatering, sump duty and haul-road water control, where volume and solids tolerance decide the selection. Flows to 3,350 m³/hr, solids to 124 mm.
Mining pumpingThe high-volume duties that dominate marine work — cofferdam and dock dewatering, reclamation, shoreline water control — where solids tolerance and flow rate matter more than pressure.
Marine pumpingAbstraction directly from rivers, lakes and reservoirs, where the water carries silt and vegetation. Flows to 3,350 m³/hr with solids handling to 124 mm.
Irrigation pumpingTrench, pad and site dewatering where the water carries solids. Flows to 3,350 m³/hr, solids handling to 124 mm, self-priming to 8.5 m.
Oil & Gas pumpingThe core municipal range: stormwater, sewer bypass, flood response and works overflow. Flows to 3,350 m³/hr with solids handling to 124 mm, plus sewage-impeller options for fibrous material.
