Slurry Pumps
Heavy-duty horizontal centrifugal slurry pumps for mill discharge, hydrocyclone feed, flotation circuits, and tailings disposal.
Slurry Pump Configuration
Engineered for high-density slurries with abrasive or corrosive solids. Each pump integrates a split outer casing, interchangeable wet-end wear parts (impeller, throatbush, volute liner, and frame plate liner insert), centrifugal expeller and stuffing box sealing (no mechanical seal), and a complete Bearing Assembly / Housing unit.
Technical Specifications
| Available Sizes | 1.5x1", 2x1.5", 3x2", 4x3", 6x4", 8x6", 10x8", 12x10", 14x12" |
|---|---|
| Wet-End Materials | 27% High Chrome (A05 ≥650 HB), Natural Rubber (R55), Polyurethane (U01), and Sintered Silicon Carbide (SiC ≥2200 HV) |
| Bearing Unit | Complete Bearing Assembly / Housing with external axial adjustment (L₁₀ₘₕ = 1.25× L₁₀h with labyrinth seal vs 0.22× contaminated) |
| Shaft Sealing | Dry centrifugal expeller and stuffing box (no mechanical seals) |
| Drive Arrangement | V-belt and pulley drive or direct coupling |
Plant Applications
- Mill Discharge & Cyclone Feed: High Chrome impeller and liners for coarse rock impact.
- Flotation & Regrind: Rubber or Polyurethane liners for fine particles and corrosive reagents.
- Tailings & Thickener Underflow: Continuous single-stage or series pumping.
Metallurgical Rule: Specify drive train with minimum 1.35 service factor. High Chrome A05 for coarse angular slurries; vulcanized rubber for fine solids under 5 mm with flotation reagents.
Critical Variables: Design flow rate (m3/h), total dynamic head TDH (m), slurry specific gravity (SG 1.1 to 1.7), d80 particle sizing (microns), and mine elevation above sea level.
Avoided Risk: Prevents skid torsional vibration, shaft deflection, and premature bearing overheating under slurry surge startup conditions.
Skid Drive & Mounting Arrangements (CV / ZVZ / CRZ / DC)
Select the drive arrangement matched to your plant floor footprint and target ISO 281 L₁₀h Bearing Assembly life:
CV Arrangement (Overhead Motor Mounted Above Bearing Assembly)
Compact overhead motor cradle mounted above the Bearing Assembly. Saves 45% floor space and protects the electric motor from sump slurry spills and flooding.
Footprint: 0.55× • Sump Flood: Elevated Motor (Splash Immune) Quote CV Arrangement Skid →ZVZ Arrangement (Elevated Rear Motor on Shared Base Frame)
Motor mounted on an elevated rear pedestal behind the Bearing Assembly with V-belt drive. Ideal for medium-to-high horsepower while keeping the motor above sump flood level.
Footprint: 0.85× • Sump Flood: Elevated Motor (Splash Immune) Quote ZVZ Arrangement Skid →CRZ / CR Arrangement (Side-by-Side Belt Drive on Shared Skid)
Motor mounted side-by-side next to the pump on a heavy structural skid with slide rails. Enables rapid sheave ratio changes (H ∝ N²) to compensate for impeller wear.
Footprint: 1.00× • Sump Flood: Baseplate level / Sump drainage Quote CRZ Arrangement Skid →DC Arrangement (In-Line Direct Flexible Coupling)
Collinear direct coupling between motor (with VFD speed control) and Bearing Assembly shaft. Zero V-belt radial overhung load on bearings (Fr = 0).
Footprint: 1.15× • Sump Flood: Baseplate level / Sump drainage Quote DC Arrangement Skid →
