NB Sand sludge pump

Robust centrifugal sand/slurry pump engineered for high-wear, high-concentration dredging and slurry-handling applications. Built for continuous operation in demanding environments, this NB series pump handles sand, gravel, tailings and abrasive slurries with high efficiency and long service life.

Key features

• Heavy-duty construction: pump body, impeller and wear plate available in high-manganese ductile iron, high-chromium alloy or non-metallic wear-resistant materials — selectable at order to match media abrasiveness.
• High solids handling: designed for mixed-phase concentrations up to 60% and typical operating concentrations greater than 40%.
• High capacity and depth: maximum mixed flow rates typically in the 2,000–5,000 m3/h range and pumping depths up to 30 m.
• Flexible drive options: compatible with electric motor or diesel engine drives to suit site power availability.
• Reliable shaft sealing: packing seal with a high-pressure flushing water system to protect the packing chamber and extend service intervals.
• Adjustable outlet orientation: default outlet is to the right (when viewed from the inlet); outlet can be rotated to any position within a full 360° on site.
• Modular design: assembled from pump body, impeller, protective/wear plate, pump cover, bracket and bearing assembly for easier maintenance and parts replacement.
• Designed for ease of installation and customization — supports bespoke material selection and configuration to match specific jobsite requirements.

Performance & typical applications

• High head, large flow and energy-efficient operation suitable for continuous pumping of abrasive slurries.
• Suited to river, lake and sea sand extraction; dredging and embankment consolidation; sand loading/unloading; tailings and mine slurry transfer; coal mine and power-plant slurry handling; hydraulic filling and land reclamation projects.

Ordering & selection guidance

• Specify required impeller and wear-plate material based on slurry abrasiveness and particle size distribution (high-manganese or high-chrome alloys for heavy abrasion; non-metallic wear parts where appropriate).
• Indicate preferred drive type (electric or diesel), required flow/head, suction depth and outlet orientation to receive a recommended model and drive package.

This NB series sand/sludge pump is engineered for operators who require a durable, serviceable pump that performs reliably in abrasive and heavy-solid slurry applications.
