Product Introduction

The gravel pump is designed for efficient transportation of strong abrasive materials that are typically too large for standard slurry pumps. This pump features a single-stage, single-suction, cantilever, horizontal structure, making it versatile across various applications such as coal, electricity, river dredging, and municipal engineering.

Gravel Pump Design and Structure

The gravel pump consists of a pump body, pump cover, and joint plate that are securely connected by a clamp band. This design allows for easy installation and maintenance. The discharge direction of the pump can be adjusted to any position within a 360-degree range, enhancing its usability in different settings. The pump is also equipped with a cylindrical bearing assembly that facilitates gap adjustments between the impeller and the pump body, allowing for straightforward maintenance.

Gravel Pump Performance Features

A gravel pump is a pump specially designed for conveying liquid media containing solid particles. Its product features mainly include:
Grease Lubrication: The lubrication system minimizes the risk of oil leakage and reduces maintenance efforts.
Wide Flow Channel: The design ensures good cavitation performance, high efficiency, and abrasion resistance.1. Strong wear resistance: The flow parts of the gravel pump are usually made of wear-resistant materials, which can effectively resist the wear of solid particles.
Efficient conveying capacity: The design can handle high concentrations of solid particles, ensuring efficient conveying efficiency.
Simple structure and convenient maintenance: The structure design of the gravel pump is simple, which is convenient for daily maintenance and repair.
Strong adaptability: It is suitable for a variety of working conditions, including but not limited to mining, construction, water conservancy and other fields.
Corrosion resistance: The flow parts can select suitable corrosion-resistant materials according to the characteristics of the conveying medium.
Adjustable flow and head: By changing the size or speed of the impeller, the flow and head of the pump can be adjusted to meet different working requirements.
Strong self-priming ability: Some gravel pumps have good self-priming ability and can be started without additional water suction devices.
Low energy consumption: Optimized hydraulic design and efficient drive system make the gravel pump have lower energy consumption during operation.

Gravel Pump Drive Mechanisms

The gravel pump supports multiple drive options to suit various operational needs:

V-shaped V-belt drive
Elastic coupling drive
Gear reducer drive
Hydraulic coupler drive
Variable frequency drive
SCR speed control

These options allow the pump to operate under optimal conditions, enhancing its service life and efficiency.

Gravel Pump Application

The gravel pump is particularly effective in environments requiring the transportation of large particles, making it ideal for:

River sand mining
Mining vessels
Dredging operations

Its ability to adapt to different speeds and configurations ensures it meets the demands of various transportation conditions while maintaining high operational efficiency.

Gravel pump stands out due to its robust design, effective lubrication system, versatile drive options, and suitability for challenging applications. Its innovative features make it an essential tool in industries dealing with abrasive materials.

Sealing mode

The shaft seal of gravel pump has packing seal and vice impeller seal.

1. Packing seal: used for suction or backflow state. Shaft seal water pressure should be higher than the pump outlet pressure 35Kpa, shaft seal water see below.

2. Vice impeller seal: generally used for backward irrigation state. The backward water head does not exceed 10% of the total water head of the pump, and the shaft power will increase by about 5%.
