Top 20 Slurry Pump Manufacturers in the World

Note: Except for BBP, which is listed first as requested, the remaining companies are presented in no particular order.
Slurry pump manufacturers are companies that design and supply pumps for liquids carrying abrasive, dense or settleable solids. Choosing among them is rarely a simple brand comparison. A pump that performs well in a dewatering sump may be unsuitable for a mill circuit, while a heavy-duty horizontal unit may be unnecessary for a mobile dredging job. The real selection problem combines hydraulic duty, solids behavior, wear materials, installation geometry, power, maintenance access, spare parts and local service.
This 2026 guide identifies 20 companies or brands with current official websites and published slurry-related ranges. “Top” means a researched shortlist for buyer investigation; it does not mean that one supplier is objectively superior in every application. BBP appears first because that placement was requested. Companies 2–20 are unranked. Before issuing a request for quotation, buyers can also review BBP’s slurry pump range and its practical guide to mining slurry pump selection.
How We Selected These Slurry Pump Manufacturers

Every listed entry passed four basic checks: it has an identifiable company or brand relationship, an official website that was accessible during research, a published slurry-related product range, and enough first-party information to describe that range without relying on marketplace listings. Firecrawl search and page extraction were used for live discovery and verification, supplemented by current Google result data and official company, product and history pages. Search-result listicles helped discover candidates but did not establish company facts.
Founding dates need careful reading. A parent group, current legal company and legacy product brand may have different dates. We therefore label entries such as Weir/Warman, Xylem’s submersible brand and KSB/GIW explicitly. Official pages support identity, public history and declared products, but they do not independently prove current factory control, regional service capacity, delivery time or local parts inventory. Those points belong in the written quotation and supplier audit.
Selection boundary: this is a manufacturer-comparison article for abrasive and solids-bearing slurry applications. It is not a generic pump-sizing guide, and it does not replace the separate wastewater-focused review of sludge pump manufacturers.
Evidence boundary: advantages below reflect verified product scope and publicly described capabilities. “Purchasing considerations” are neutral questions to resolve before award, not allegations of product defects.

Website — official: https://www.gouldspumps.com/
How to Verify a Slurry Pump Bid: The Post-Quote Evidence Check

The buyer’s initial request for quotation should already define the duty and commercial scope; BBP’s industrial pump RFQ specification guide covers that earlier step. The Post-Quote Evidence Check begins after bids arrive. A catalog shows what a supplier offers, but it does not prove that the quoted configuration will work in your system. Request the same six returned files from every shortlisted supplier so the bid comparison is based on evidence rather than different sales formats.
Illustrative duty-sheet format—not recommended operating values: a completed project sheet might show minimum/normal/maximum flow of 120 m³/h, 150 m³/h and 180 m³/h (approximately 528 gpm, 660 gpm and 793 gpm); head of 28 m, 32 m and 36 m (about 92 ft, 105 ft and 118 ft); solids of 25 wt%, 30 wt% and 35 wt%; mixture density of 1,250 kg/m³, 1,350 kg/m³ and 1,450 kg/m³; particle values of 0.2 mm, 0.8 mm and 6 mm; temperature of 15 °C, 25 °C and 40 °C (59 °F, 77 °F and 104 °F); speed of 900 rpm, 1,050 rpm and 1,200 rpm; power of 55 kW, 75 kW and 90 kW (approximately 74 hp, 101 hp and 121 hp); suction pressure of 0.8 bar, 1.0 bar and 1.2 bar (about 11.6 psi, 14.5 psi and 17.4 psi); supply frequency of 50 Hz or 60 Hz; and motor voltage of 400 V or 460 V. These figures are fictitious placeholders that demonstrate the required units and three-point structure. They must not be used to select a pump.
- Begin with the duty and slurry data sheet. Record minimum, normal and maximum flow (m³/h); static and friction head (m); suction pressure (bar); altitude (m); temperature (°C); liquid chemistry; solids concentration (wt% and vol%); mixture density (kg/m³); specific gravity; particle-size distribution and maximum particle size (mm); hardness; particle shape; corrosiveness; entrained air and the expected wear mechanism. Include the system curve and operating scenarios.
- Next, obtain a hydraulic selection file. Require the selected model, speed (rpm), impeller diameter (mm), absorbed power (kW), efficiency (%), net positive suction head (m) and operating point. Distinguish a family selection chart, a published performance curve and a certified curve for the purchased pump and impeller trim.
- The third file covers materials and traceability. List casing, impeller, liner, shaft, sleeves, elastomers and fasteners with material standards or supplier grades. Define certificates, heat or batch traceability, hardness checks and any inspection hold points.
- Before production, agree on the acceptance-test plan and report. State the governing standard, acceptance grade, test medium, instrumentation, tolerances, witness points and report format. A clean-water test can validate hydraulic manufacture under its stated basis, but it does not alone prove abrasive slurry performance.
- For maintenance planning, collect spares and interchange evidence. Request a two-year recommended spares list, drawings, part numbers, shelf-life notes, local stock statement and dimensional or drawing evidence for any claimed interchangeability. Review BBP’s slurry pump spare-parts guide when building this list.
- Close the package with a service and logistics plan. Identify manufacturing location, inspection responsibility, packaging, export documents, shipping terms, installation supervision, commissioning, warranty process, repair location and response path. Ask for current lead times in the quotation rather than copying them from an old project.
| Evidence checkpoint | Comparison question | Clarify before award |
|---|---|---|
| Duty sheet | Is the same operating envelope used by every bidder? | Missing minimum, normal or maximum case |
| Slurry characterization | Are concentration, density and particle data quantified? | Generic “abrasive slurry” description |
| Hydraulic selection | Is the quoted operating point shown on the curve? | Family chart without purchased configuration |
| Materials schedule | Are all wetted parts and grades identified? | Unqualified “wear-resistant” wording |
| Traceability plan | Which records follow the supplied components? | Certificate scope not tied to parts |
| Acceptance-test plan | Are test basis, medium and acceptance criteria stated? | Catalog curve offered as test evidence |
| Spares schedule | Are current part numbers and stocking responsibilities clear? | Interchange claim without drawings |
| Service plan | Who owns commissioning, warranty and repair response? | Regional responsibility left undefined |
| Commercial schedule | Do price, exclusions and lead-time basis align? | Low bid with unresolved technical exclusions |
Important test caveat: ISO 9906 hydraulic acceptance testing applies to liquids that behave like clean, cold water. If a supplier presents an ISO 9906 certificate, ask what it proves about the manufactured pump and what separate correction or application basis is used for slurry density, viscosity, solids and wear.
The actual operating point comes from the intersection of the pump and system curves. It can move when solids concentration, pipe condition, valve position, speed or impeller diameter changes.
The Four-Handoff Risk Chain

Many failures begin between departments rather than inside one component. Use this four-handoff chain to decide where the quotation needs an owner and a written acceptance point.
A U.S. Mine Safety and Health Administration investigation illustrates why pump-maintenance procedures and responsibilities must be explicit before work begins.
- Process data → hydraulic selection: incomplete solids or system data can put the selected centrifugal pump away from its intended operating region, increasing recirculation, vibration, power demand or unstable flow.
- Hydraulic selection → materials: correct head and flow do not prevent excessive wear when the impeller, casing or liner does not match abrasion, impact and corrosion.
- Materials → manufacturing and testing: the specified alloy or elastomer must survive casting, machining, balancing, assembly and inspection with traceable records.
- Shipment → site support: a technically correct pump can still lose availability when cables, starters, seals, tools, replacement parts or trained service are missing.
This chain also explains why the lowest purchase price may not produce the lowest total cost of ownership. Compare expected maintenance intervals, energy at the actual operating point, shutdown consequences, spares and service—not an unsupported promise of wear life.
Which Type of Manufacturer Fits Your Application?

Use the Hydraulic Institute slurry-pump terminology and application framework as a common technical vocabulary before comparing the supplier categories below. It separates pump-architecture fit from later curve, materials, acceptance-test, spares and service comparisons for the stated duty in each project.
For mill circuits and mineral processing: prioritize manufacturers with documented mill-discharge, froth, high-head and vertical sump experience. Review how the supplier handles changing density, abrasive solids, operating region and wet-end material selection. This narrows the pump architecture before commercial comparison begins.
For dredging and excavation: compare dredge pumps, hydraulic or electric drive, agitators, cutters, pontoons and excavator interfaces as one system. A high-solids pump without the correct feed mechanism may not deliver the expected production.
For submerged sumps and mobile dewatering: submersible slurry pumps from Xylem, Tsurumi, Dragflow, Hevvy/Toyo, Goodwin and other specialists may reduce priming and installation complexity. Motor cooling, cable protection and lifting remain part of the duty.
For corrosive or mixed abrasion-corrosion service: ask for the material-selection reasoning, not merely a “wear-resistant” label. Metal hardness, rubber compound, particle impact and chemical attack can pull selection in different directions.
For replacements: verify shaft centerline, flange drilling, base dimensions, rotation, curve, materials, power and part drawings. The phrase “replacement pump” does not automatically mean every part is interchangeable.
Frequently Asked Questions
Which company makes the best slurry pump?
No single slurry pump manufacturer is best for every duty. Mill-circuit, submersible agitator, filter-press feed and dredge pumps solve different problems. Separate dry-installed, cantilever, submersible and dredging architectures first. Then compare the operating point, allowable region, wet-end materials, seal arrangement, power, test basis, spares and site support. The best shortlist is the one whose documented evidence matches the complete duty sheet and the consequences of downtime. Require written confirmation of the purchased configuration and support available near the plant.
What is the difference between a slurry pump and a dredge pump?
A slurry pump is a broad category for mixtures containing solids. A dredge pump is configured for excavation or transport of sediment, often with large passages, high solids handling, an agitator or cutter, and a floating or excavator-mounted system. Some dredge pumps are slurry pumps, but many plant slurry pumps are not dredging packages. Confirm the feed method, mounting interface, discharge route, driver, controls and lifting plan together, because pump capacity alone does not define a complete working dredging system.
What information should I send to a pump supplier?
Send flow and head ranges, a system curve, suction conditions, pipe data, solids concentration, specific gravity, particle distribution and maximum size, hardness and shape, liquid chemistry, temperature, installation layout, motor supply, operating schedule, maintenance constraints and required standards. Photos and samples help but do not replace quantified duty data.
Do slurry pump manufacturers supply replacement parts and service?
Many do, but coverage varies by model and region. Ask for current part numbers, drawings, recommended stock, manufacturing location, local inventory, repair capability, warranty route and response responsibility. Obtain those commitments in writing for the destination site, and identify who owns each after-sales obligation.
How do I get a certified pump curve?
Define the purchased model, impeller trim, speed, test standard, acceptance grade, test medium and witness requirement in the request for quotation. A catalog or published family curve is useful for selection, but it is not the same as a certified result tied to the supplied configuration.
Final Shortlisting Advice

Start with application fit, not company size. Select three to five manufacturers whose pump architecture matches the installation, then apply the same Post-Quote Evidence Check to each bid. Compare exclusions as carefully as inclusions. If one quotation omits the system curve, solids data, material traceability, test basis or spare-parts route, its lower price is not yet comparable.
At an operating mine, a missing wear part or undocumented factory acceptance test (FAT) can turn routine maintenance into prolonged downtime. Treat a quotation with no current stock plan or test basis as incomplete. Search pages may describe candidates as industrial slurry pump manufacturers, the best slurry pump manufacturers, the largest slurry pump manufacturers or small slurry pump manufacturers. Those labels are not technical selection evidence.
Search interest for “slurry pump manufacturers” has risen in recent data, but that is an information-demand signal—not proof of higher tender volume, mine throughput, capital expenditure or pump orders. The useful response is better sourcing discipline. To discuss a documented duty with BBP, contact the engineering team and send the operating data before requesting a final selection.

BBP engineers will recommend a pump series, material option, duty curve basis, lead time and spare-parts plan for your RFQ.
