D、DG Horizontal Multistage Centrifugal Pump

I. Product Overview

The D and DG series pumps are horizontal, single-suction, multistage, sectional centrifugal pumps. They feature high operating efficiency, a wide performance range, safe and stable operation, low noise, long service life, and ease of installation and maintenance. They are designed to transport clean water or other liquids with physical and chemical properties similar to water. By modifying the materials of flow-passage components and the sealing method, or by adding a cooling system, they can also be used to transport hot water, oils, corrosive media, or media containing abrasive particles. These products comply with the JB/T1051-93 standard ("Types and Basic Parameters of Multistage Clean Water Centrifugal Pumps").

Our products are designed and optimized using computer-aided technology. Backed by strong technical expertise, extensive manufacturing experience, and comprehensive testing capabilities, we ensure consistent and reliable product quality.

II. Applications

Suitable for industrial and municipal water supply and drainage, high-rise building water supply boosting, landscape sprinkler irrigation, fire-fighting pressure boosting, long-distance water transport, heating systems, hot and cold water circulation boosting (e.g., for bathrooms), and as auxiliary equipment for other systems; particularly suitable for small boiler feed water applications.

III. Product Features

1. Advanced hydraulic model, high operating efficiency, and wide performance range.

2. Stable pump operation and low noise levels.

3. Shaft sealing utilizes either soft packing or mechanical seals; the sealing is safe and reliable, with a simple structure that allows for quick and easy maintenance.

4. The shaft features a fully sealed design, ensuring no contact with the pumped medium; this prevents corrosion and extends service life.
