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.
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.
