Section 43 23 13 — Centrifugal Pumps for Slurry / Mining Duty
MasterFormat classifies this as Overhung Horizontal Centrifugal Pumps — there is no dedicated "slurry pump" section. Real Schurco Slurry USA S/L/H/V/U series data for the mining-duty spec written under this general category.

Section 43 23 13 (Overhung Horizontal Centrifugal Pumps) sits under Division 43 20 00 (Liquid Handling Equipment). MasterFormat does not have a distinct section number for "slurry pumps" or "mining pumps" — a heavy-duty abrasive-slurry centrifugal pump is specified within this same general category, with the abrasive/corrosive/high-solids duty driven by material selection (liner, impeller, seal architecture) rather than a different CSI code. Verify any spec that cites a different number for slurry-specific pumps before treating it as a real MasterFormat classification.
Provide This to Get a Real Match Against the Section
| What to Provide | Why It Matters |
|---|---|
| Solids content (% by weight) and particle size | Determines liner material (metallic vs. elastomeric), impeller design, and whether a slurry-rated pump family is required at all versus a standard centrifugal. |
| Specific gravity of the slurry | Directly changes head/flow performance and driver sizing — Schurco's own spec tables are published against clear water, and SG must be applied as a correction factor. |
| Required flow (gpm) and head (ft) | Schurco's 7-series lineup spans a wide range — S Series (max 22,000 gpm) to L Series (max 30,000 gpm, the highest-volume pump in the catalog) to H Series (max 750 psig at only 3,000 gpm) — the duty point picks the series, not the other way around. |
| Abrasiveness / chemical corrosivity of the process fluid | Determines metallic-liner vs. elastomeric-liner vs. unlined high-chrome-alloy (U Series) construction, and whether a combined corrosion+abrasion material (e.g. glass-ceramic matrix composite) is needed elsewhere in the circuit. |
| Duty cycle — continuous vs. intermittent, sump/pit application | Governs seal architecture selection — Schurco's V Series is fully cantilevered with no submerged bearings, seals, or packing, purpose-built for sump/pit/tank service where a submerged shaft seal is a liability. |
Schurco Slurry USA — 5 of 7 Series
| Series | Material | Size / Capacity | Notes |
|---|---|---|---|
| S Series | Metallic or elastomeric liners | Discharge 1"-18", head max 240ft, flow max 22,000 gpm, working pressure max 300 psig | General-duty heavy slurry pump. |
| L Series | Alloy or thick elastomer liners | Discharge 4"-22", head max 180ft, flow max 30,000 gpm, working pressure max 250 psig | Highest-volume pump in the catalog; 90+% efficiency. |
| H Series | High-chrome liners | Discharge 1"-6", head max 325ft, flow max 3,000 gpm, working pressure max 750 psig | The clear high-pressure outlier — low flow, high head/pressure tradeoff. |
| V Series | 27% chrome alloy casing (metal) or molded rubber casing | Discharge 1.5"-10", head max 160ft, flow max 4,500 gpm | Fully cantilevered — no submerged bearings, seals, or packing; double-suction impeller eliminates shaft seals for sump/pit service. |
| U Series | Unlined, high-chrome alloy hardened >650 Brinell | Discharge 2"-10", head max 240ft, flow max 6,000 gpm, working pressure max 150 psig | Unlined construction — the alloy itself is the wear surface. |

Section 43 23 13 FAQ
Is there a dedicated CSI MasterFormat section number for "slurry pumps"?
No — MasterFormat does not carve out a distinct number for slurry pumps. The applicable general category is Section 43 23 13 (Overhung Horizontal Centrifugal Pumps) under Division 43 20 00 (Liquid Handling Equipment). Slurry/abrasive-solids duty is a specification detail — liner material, wear-part hardness, impeller design — applied within this general section, not a separate CSI number. Any specification claiming a distinct "slurry pump" MasterFormat code should be verified, not assumed.
What determines which Schurco Slurry series to specify?
The duty point — flow, head, and working pressure — determines the series first, then solids content and abrasiveness determine liner material within that series. The S Series covers the broadest general-duty range; L Series is the highest-volume option at up to 30,000 gpm; H Series trades flow for pressure (up to 750 psig at only 3,000 gpm max); V Series is purpose-built for sump/pit service via its cantilevered, sealless design.
When is an unlined high-chrome-alloy pump (U Series) the right call instead of a lined pump?
When the wear surface itself needs to be the hardened material rather than a replaceable liner — U Series uses unlined, high-chrome alloy hardened above 650 Brinell, where the alloy body is the wear surface. Lined pumps (S/L Series) let the liner absorb wear and be replaced without the pump casing itself wearing out, which is the more common choice for continuous heavy-solids duty.
What seal options are available across the Schurco slurry pump line?
Three shared options across the line: Stuffing Box (packing rings, requires seal water), Expeller (waterless centrifugal seal for moderate suction conditions), and cartridge-style Mechanical Seal for high-pressure, high-temperature, or corrosive/abrasive slurries. The V Series avoids this decision entirely via its sealless cantilevered design.
