PNL Series Vertical Mud Pumps

PNL Series Vertical Mud Pumps
The PNL Series Vertical Mud Pumps are engineered for demanding applications across industries such as mining, infrastructure, environmental protection, metallurgy, and marine construction. These single-stage, single-suction cantilever pumps excel in transporting abrasive slurries, sewage, and high-density mixtures (up to 50–60% concentration by weight). Ideal for drilling, dredging, and slurry handling, models like the 3PNL and 4PNL are particularly suited for construction and mining operations.

Key Features

• Adjustable Efficiency: The impeller, pump body, and guard plate clearance can be adjusted in real time, ensuring sustained high efficiency and extended service life.

• Wear-Resistant Construction: Overflow components feature high-chrome alloy or wear-resistant cast iron options, combating abrasion in harsh environments.

• Simplified Maintenance: Split-pump casing and horizontal split bracket design enable quick disassembly, inspection, and part replacement.

• Advanced Cooling System: Water-cooled serpentine tubes in the oil pool optimize bearing performance, even under heavy loads.

• Versatile Drive Options: Compatible with electric motors or diesel engines, offering flexibility in remote or industrial settings.

• Vertical Design: Space-saving vertical shaft configuration with a closed impeller ensures steady operation and reduced vibration.

Technical Specifications

• Flow Rate: 7.2–320 m³/h (30–150 m³/h standard range; higher capacities available in specific models).

• Head: 14–50 m (15–26 m typical for drilling applications).

• Power: 11–22 kW (customizable for varying operational demands).

• Max Particle Handling: Designed for slurries with sand, gravel, and sludge up to 60% concentration.

• Materials: High-chrome alloy, wear-resistant cast iron, and rubber seals for enhanced durability.
