​In the world of industrial machinery, selecting the right pump is critical for optimizing performance and efficiency. Two common types—double-suction pumps and single-suction pumps—are widely used across industries such as water treatment, HVAC, and chemical processing. While they share similarities, their designs, functionalities, and applications differ significantly. Let’s explore these distinctions to guide your decision-making.

​In fluid and piping systems, pumps serve as vital conveyance devices across multiple industries, including oil and gas, chemicals, water treatment, and aerospace. This article compares single-suction and double-suction pumps from perspectives such as flow capacity, structure, working principle, efficiency, and application scenarios.
