Use published BQR cell ranges and project models to check drawings, materials and supply for rotors, stators, tank liners, launders, level valves, shafts and drives.
DELKOR BQR cells serve rougher, scavenger, cleaner and recleaner stages. Current manufacturer information describes MAXGen™ rotor/stator combinations, customized launders and froth crowders, internal/external dart-valve level control, and segmented stators and crowders for large cells. Enquiries must confirm full BQR model, volume, project or serial number, internal position, rotor/stator design, launders, valves, liners, shafts, drive and drawing revision.
Only cell ranges, models and project combinations traceable to current DELKOR product and project pages are listed. Equal BQR model names, similar volumes or the same ore type do not establish direct interchangeability of rotors, stators, shafts, liners, launders, valves or drives.

| BQR 700 / BQR 500 | 5 × BQR 700; 9 × BQR 500 | South African PGM project with larger mechanisms; confirm specific spares against project drawings | Project published in 2025 |
| BQR 300 / BQR 200 / BQR 100 | 4 × BQR 300; 10 × BQR 200; 9 × BQR 100 | Lead-zinc polymetallic project in Bosnia and Herzegovina; models, cell counts and ore type are installation identifiers only | Project published in 2024 |

| Froth launder |
Current manufacturer information describes MAXGen™ rotor/stator combinations, segmented stators and crowders, and peripheral, radial or combined launders. Confirm wear parts by cell model, flotation stage, slurry, size, concentration, chemical medium, speed, structure and drawings. One project's rubber lining or construction is not a fixed solution for all BQR cells.
MAXGen™ Rotor & Stator Assembly
The current page describes an improved rotor/stator combination and segmented stators for large cells. Check rotor diameter, blade/hub design, stator sections, holes, shaft ends, rotation, speed, installation height and old-part wear.
Open the shared component catalogue →Tank Liners, Feed-Zone & Bottom Protection
Identify tank liners, feed-box protection, lower manhole surrounds and high-wear areas. Manufacturer project records mention rubber lining, but actual construction, thickness, material and drawing require the specific tank and service conditions.
View the common part page →Launders, Froth Lips & Segmented Crowders
Published launders may be peripheral, radial or combined, with customized crowders; large cells may use segmented crowders. Check launder type, froth lip, sections, supports, connections, cleaning and froth-flow direction.
View the common part page →Preserve the complete BQR designation as marked. The OEM page documents BQR 400 as a 40 m³ reference. Identify the installed MAXGen mechanism independently of tank size. source
Fields to request: manufacturer as marked; full type/model; serial number; build year if shown; plant tag; a sharp full-plate photograph. Collect the extra technical fields below from equipment records when they are not printed on the plate.
full_BQR_type; volume_as_marked; MAXGen_revision; stator_segments; dart_valve_supplier; internal_external_valve; launder_layout
BQR transmission, level-control and structural parts require specific cell, project and drawing checks. Current information describes internal/external dart valves, bottom manholes for internal-part removal, modular walkways, individual-cell bypass and optional bolted tanks, but no complete OEM spare-number table.
Rotor Shaft, Bushings, Bearings & Drive Interface
Confirm BQR model, cell volume, shaft ends, rotor design, bushings, bearings, seals, gearbox, motor, coupling, mounting base and rotation. Shafts are commonly matched with the rotor/stator set.

Internal / External Dart Valves & Level-Control Parts
The current page lists internal and external dart valves; the Wiluna project describes dart plugs and dual-outlet froth-discharge boxes. Check valve body, plug, actuator, seals, piping, interfaces, control logic and cell-stage position.
View the common spare-parts catalogue →Tank Sections, Manholes & Structural Connections
The current page offers optional bolted tanks and bottom manholes for removing internal parts. Provide general arrangement, sections, flanges, bolts, access doors, manholes, sealing faces, welding and acceptance requirements.
View the common spare-parts catalogue →Modular Walkways, Cell Bypass & Maintenance Interfaces
Modular walkways support flexible maintenance layouts, and individual-cell bypass enables faster servicing. Check platforms, handrails, bypass piping, flanges, valves, access positions and safety standards against the project.
View the common spare-parts catalogue →Provide full BQR model, project or serial number, cell volume, flotation stage, rotor/stator, launders/crowders, valves, liners, shafts, drive, drawing, used-part photos, key interfaces, material and slurry conditions.
Not without checking. Flotation stage, mechanism revision, tank, launders, liners, shafts, drives, modifications and drawing revisions may differ. Confirm installation records and actual interfaces.
Provide full model, project number, serial number, cell volume, flotation stage, rotor/stator, launders, valves, liners, shafts, drawings, used-part photos, material and slurry conditions for consulting, sourcing, quality control and finished-part delivery.
