FGD, Ash Handling, Coal Prep, Slag Granulation & Heavy Media Slurry Pumps
Four real, distinct sectors — power generation (FGD, ash handling), coal processing (coal prep, heavy media), steel/metals (slag granulation), and food/chemical (salt production, sugar beet) — each named individually across Schurco Slurry's seven pump series, not one generic "Mining" application.
Heavy-duty slurry pumping spans four distinct sectors: power generation (FGD and ash handling), coal processing (coal prep and heavy media), steel (slag granulation) and food or chemical (salt production, sugar beet). Match the Schurco Slurry series to its named application. The P Series is built for light slurry near specific gravity 1.05 and is not a heavy-slurry pump.
Match the Series to the Named Application, Not a Generic Slurry Bucket
Schurco Slurry publishes named application lists per series — not a single generic "slurry" or "mining" market. The application named on the series' own catalog page is the strongest available evidence for which series fits which duty.
FGD & Ash Handling (Power Generation)
Flue-gas desulfurization absorber recirculation and ash sluice duty — high-volume, moderate-pressure slurry transfer inside a coal- or gas-fired power plant, not a mining application.
Coal Preparation & Heavy Media (Coal Processing)
Coal washing circuits plus dense-medium (magnetite/ferrosilicon) separation loops, where the medium itself is abrasive and continuously recirculated — a distinct selection problem from raw coal transport.
Slag Granulation & Salt Production (Steel/Metals & Food/Chemical)
Molten-slag quenching and granulation at a steel mill, and salt production — two applications with nothing in common with mining except abrasive-solids handling.
Coal Prep Floor & Sump Duty
Effluent handling and floor/sump pumping inside a coal prep or FGD plant, where a conventional vertical pump's submerged seal is the recurring failure point.
All Seven Schurco Slurry Series — Real Catalog Spec Data
| Series | Discharge | Head (max) | Flow (max) | Working Pressure (max) | Liner / Construction | Named Applications |
|---|---|---|---|---|---|---|
| L Series | 4"–22" | 180 ft | 30,000 gpm | 250 psig | Alloy or thick elastomer liners | Aggregate Production, Ash Handling, Chemical Process, Coal Preparation, Cyclone Feed, FGD applications, Mine Dewatering, Mineral Processing |
| S Series | 1"–18" | 240 ft | 22,000 gpm | 300 psig | Interchangeable metallic or elastomeric liners | Aggregate Production, Coal Preparation, Cyclone Feed, Heavy Media, Mill Discharge, Ore Transport, Plant Process, Tailings |
| Z Series | 4"–14" | 225 ft | 12,000 gpm | 200 psig | Rotatable segmented/solid clamp-ring casing (3-piece) | Dredging, Hydraulic Mining, Large Particle Applications, Low NPSHa, Salt Production, Slag Granulation, Sugar Beet Processing |
| V Series | 1-1/2"–10" | 160 ft | 4,500 gpm | not published | Fully cantilevered — no submerged bearings, seals or packing; metal (27% chrome alloy casing) or rubber (molded on metal structure) | Coal Prep, Effluent Handling, Floor Pumps, Sump Pumps |
| H Series | 1"–6" | 325 ft | 3,000 gpm | 750 psig | High-chrome liners | High-pressure outlier of the seven series — precision-vs-throughput tradeoff, not a bulk-transfer pump |
| U Series | 2"–10" | 240 ft | 6,000 gpm | 150 psig | Unlined, high-chrome alloy hardened >650 Brinell | Unlined severe-abrasion duty where liner replacement cost outweighs liner benefit |
| P Series | 4"–6" | 420 ft | 2,250 gpm | 240 psig | Wear-resistant alloy wet end | CAUTION: for light slurries at specific gravity ~1.05 only — explicitly not a heavy-slurry pump |

The P Series Is Not a Heavy-Slurry Pump
Schurco's P Series (4"–6" discharge, 420 ft head, 2,250 gpm, 240 psig) shares the same catalog family as the six series above, but its wear-resistant alloy wet end is built for light slurries at specific gravity around 1.05 — closer to water than to FGD absorber slurry, coal-wash medium, or granulated slag. Specifying P Series onto a heavy-media or slag-granulation duty is a real vendor-flagged mismatch, not a substitution.
Pairing: AVCO 6100 Series Knife Gate Valve
AVCO does not name FGD, ash handling, or coal prep directly, but the 6100 Series (2"–24", ANSI Class 150, 304SS/316SS/Hastelloy body and shim) is the real solids-isolation pairing for the Schurco series above: gates are polished and lapped on both sides with a machined bevel on the bottom edge specifically designed to cut through solids and seal tighter closed — the same solids-laden isolation problem these pumps are sized for.
Frequently Asked Questions
Why does FGD/ash-handling equipment need its own sector page instead of "Mining"?
Flue-gas desulfurization and ash handling are power-generation applications, not mining — the absorber recirculation and ash sluice duty happen inside a coal- or gas-fired power plant. Schurco Slurry names FGD applications and Ash Handling directly on its L Series product page, alongside Coal Preparation, but a "Mining" bucket erases that distinction and can misroute a power-plant buyer searching for FGD-specific equipment.
What is the difference between Coal Preparation and Heavy Media duty?
Coal Preparation is raw coal washing and transport. Heavy Media is dense-medium separation — magnetite or ferrosilicon medium that is itself abrasive and continuously recirculated through the circuit, not just transported once. Schurco's S Series names both directly and offers interchangeable metallic or elastomeric liners specifically because the medium recirculation changes the wear profile.
Is slag granulation a mining application?
No — slag granulation is a steel and metals application: quenching and granulating molten slag byproduct at a steel mill. Schurco's Z Series names Slag Granulation directly alongside Salt Production and Sugar Beet Processing, none of which are mining. The Z Series' rotatable clamp-ring casing is a real install advantage in a granulation pit where discharge orientation is fixed by existing structure.
Which Schurco series should never be specified for heavy slurry?
The P Series. It carries a real vendor caution: it is built for light slurries at specific gravity around 1.05 and is explicitly not a heavy-slurry pump, despite sharing the same general product family as the six heavy-duty series covered on this page.
