This Froth Slurry Pump adopts modular double-casing lattice-compatible framework, inheriting mature heavy-duty slurry-pump platform while upgrading inlet flow channel and inducer semi-open wide-vane impeller for three-phase frothy-slurry handling. Wetted components including impeller, volute liner, throat bush and guard plates support high-chromium white iron, abrasion-resistant rubber or cast polyurethane material selections to cope with particle erosion and mild chemical corrosion.We supply mineral-process-oriented hydraulic selection report, factory pre-run inspection document, operation-maintenance manual and complete export technical paperwork. Custom-fit OEM manufacturing and full array of interchangeable wear-resistant spare components are offered for concentrator site retrofits and new-plant construction.

Product Advantages
Three-phase Solid-liquid-froth Adaptability
Upgraded tangential suction chamber and pre-defoaming flow path lower internal gas accumulation risk; semi-open wide-vane inducer impeller mechanically shears froth bubbles to stabilize incoming flow for flotation-circuit concentrates.
Modular Double-casing Robust Layout
Outer pressure-bearing casing stays intact; only inner consumable wetted-parts require periodic replacement. Outlet multi-angle adjustment simplifies on-site pipeline revamping for existing mineral-plant upgrades.
Flexible Multi-material Wetted-part Matching
Alternatives of high-chromium alloy, rubber and polyurethane accommodate variable particle hardness, particle shape and slight corrosive ion content inside frothy mineral slurry.
Shock-resistant Reinforced Bearing Unit
Heavy-duty cartridge-style bearing housing absorbs pulse-type load brought by uneven froth inflow; multiple interchangeable shaft-seal modules adapt variable on-site sealing-water supply conditions.
Good Compatibility With Existing Mine Infrastructure
Main-dimension interfaces keep consistent with conventional heavy-duty slurry-pump series; site-users can finish partial-unit retrofitting without massive foundation or pipeline rework.
Full-set Spare-part Logistics Support
Interchangeable wear-resistant components can be supplied on short lead-time; modular disassembly reduces overhaul man-hours and shortens concentrator unexpected-downtime duration.
Product Customization
· Hydraulic-structure Tuning: Optimize suction-chamber dimension and inducer-impeller profile based on actual froth volume fraction, solid content and fluctuation amplitude of flotation-cell discharge flow.
· Wetted-part Material Selection: Pick high-chromium alloy, rubber or polyurethane according to mineral particle hardness, sharpness and trace corrosive-ion level of on-site frothy slurry.
· Performance-parameter Calibration: Modify impeller outer dimension, rotating-speed and drive solution to satisfy target flow-head working-point of flotation-loop transfer duties.
· Shaft-seal & Auxiliary Configuration: Select expeller seal, packing seal or mechanical seal; configure special overflow bypass assembly for sites with extremely unstable incoming froth feed.
· OEM & Project-oriented Service: Accept customer-branded OEM fabrication; produce strictly against client-submitted CAD drawings; deliver pre-assembly checking service plus export-targeted packaging scheme.
FAQ
Q: What practical risks will occur if applying conventional heavy-duty slurry pump for three-phase frothy-slurry flotation concentrate?
A: Conventional slurry pumps lack specialized froth-decomposing flow-path design; accumulated entrapped gas triggers air-binding, resulting in flow swing, sharp vibration, periodic loss of delivery capacity and accelerated wear of bearing assemblies.
Q: What site-condition data needs submitting for formal quotation of Froth Slurry Pump?
A: Please provide expected flow and head requirement, froth volume percentage, solid-phase weight-concentration, mineral particle feature, feed-flow fluctuation severity, sealing-water availability and destination port information.
Q: Is it feasible to perform partial retrofitting of existing slurry-pump unit into froth-slurry-pump configuration at mineral concentrator?
A: Yes. Under premise of matching bearing-cartridge and mounting dimension, we can supply modified suction-chamber plus special inducer-impeller kits for field conversion without large-scale civil reconstruction work.
