NL Series Vertical Sand Pump for Sand and Gravel Handling

I. Product Overview

The NL series vertical sand pump is an industrial pump designed for transporting liquids containing sand. It is primarily used to extract and convey a mixture of water and solid particles—such as sand or gravel—to a designated location.

Featuring a vertical pump body design with a side discharge outlet, the series includes three models: NL80, NL100, and NL150, with a flow rate range of 50–250 m³/h. Each model offers specific flow rates, head capacities, and power ratings, allowing purchasers to select the equipment best suited to their operational requirements.

II. Applications

• The NL series sand pump is suitable for industrial operations that involve the transport of mixtures containing sand, water, and solid particles. Key applications include:
• Sand and Gravel Transport: Used during the extraction and transfer of sand and gravel, moving sand-laden liquids from one operational area to another.
• Sand and Gravel Processing: Employed in processing facilities to transport sand-containing liquids between various stages of the production process.
• Mining Operations: Utilized in mining to transport slurries containing sand, in accordance with the equipment’s handling specifications and broader material-processing workflows.
• Sediment Removal: Used in scenarios requiring the extraction of water and sand mixtures, facilitating the removal of accumulated sandy deposits.
• When selecting a model, purchasers should consider factors such as the composition of the medium, particle size, required flow rate, head, and on-site installation conditions to ensure the equipment is appropriate for the intended use.

III. Core Features

• Transport of Sand-Laden Media: Designed for the extraction and conveyance of liquid media containing solid particles, such as sand.
• Multiple Flow Rate Options: Available in three distinct models to accommodate various industrial flow rate requirements.
• Vertical Design: Features a vertical pump body configuration with a side discharge outlet.
• Variable Power Configurations: Offers different power ratings across the models, enabling purchasers to choose the unit that aligns with their specific transport needs.
• Standardized Rotational Speed: All three models operate at a rated speed of 1450 r/min. IV. Procurement Motivations
• For industrial equipment distributors, sand and gravel processing enterprises, and bulk purchasers, the NL series of vertical sand pumps offers a variety of models designed to meet diverse flow rate requirements.
• Expanding Private-Label Offerings: This series can be integrated into an existing industrial pump product line, adding sand pumps to a company’s own brand portfolio.
• Bulk Retail and Supply: With three models featuring different flow rates and power configurations, distributors can easily curate product combinations tailored to the specific needs of their downstream clients.
• Procurement Cost Planning: Purchasers can compare various models based on required flow rate, head, and power to select equipment that aligns precisely with project specifications.
• For overseas buyers, it is crucial to identify the specific challenges clients face during sand and gravel transport—such as insufficient flow rates, varying vertical transport height requirements, or a mismatch between equipment specifications and on-site operating conditions. Clarifying these needs ensures the selection of the most appropriate model.

V. OEM/ODM Information

The current product documentation does not contain information regarding OEM/ODM customization. Consequently, details concerning brand customization, aesthetic modifications, structural adjustments, and the scope of available manufacturing services should be verified directly with the manufacturer.

VI. Addressing Customer Pain Points

Industrial sand and gravel transport projects typically require the selection of a pump model based on actual operational volume. A mismatch between equipment flow capacity and on-site requirements can disrupt material transport schedules.

The NL series offers three flow rate specifications—50 m³/h, 150 m³/h, and 250 m³/h. By evaluating these alongside parameters such as head, power, and suction lift, purchasers can minimize procurement issues stemming from the selection of an unsuitable model.

All three models feature a rated suction lift of 7–9 meters, which serves as a reference for assessing on-site installation conditions. Suitability should always be confirmed against specific operating conditions prior to actual use.

VII. Industrial Procurement and Product Selection

The NL series of vertical sand pumps is primarily targeted at industrial equipment purchasers, sand and gravel processing enterprises, suppliers of mining-related equipment, and distributors of pump products.

• Before proceeding with procurement, it is recommended to verify the following:
• Required transport flow rate.
• Required operating head (vertical lift).
• Composition and particle size of the material being transported.
• Power requirements for the equipment.

Installation location and suction conditions. This information helps buyers determine which model—NL80, NL100, or NL150—best aligns with the requirements of their specific projects.
