PN Mud Pumps

The PN mud pump is a single-stage, single-suction centrifugal pump, available in both horizontal and vertical configurations. It is specifically engineered for handling abrasive slurries containing solid particles such as sand, mud, and small debris, with maximum concentrations reaching 50–60% by weight.

Key Features of PN Mud Pumps

Durable Construction: Critical wear-resistant components are made from High-chromium Alloy or Wear-resistant cast iron, ensuring extended service life.
Efficiency Maintenance: The open-type impeller, secured via a threaded shaft, allows adjustable clearance between the impeller and the front liner, maintaining high operational efficiency.
Advanced Bearing System: Models above 4 inches feature horizontally split bearing brackets with water-cooling pipes in the oil chamber, improving heat dissipation and reliability.
Ease of Maintenance: Pumps above 8 inches incorporate a split-case design, facilitating easy inspection, part replacement, and servicing.

Applications of PN Mud Pumps

This pump is widely utilized across various industries for transporting solid-liquid mixtures, including:

Mining & Metallurgy: Ore slurry transport.
Power Plants: Hydraulic ash handling.
Municipal & Construction: Slurry transfer with suspended solids.
Other Sectors: Chemical, dyeing, papermaking, textile, food, and feed processing.

Important Note

The impeller is threaded onto the shaft. Incorrect reverse rotation may cause the impeller to loosen and detach, leading to potential failure. Ensure correct motor rotation direction during installation.

This robust and versatile pump series combines reliable performance in demanding slurry applications with practical maintenance features for long-term operational efficiency.
