How a double-suction pump works
Release date:
2025-02-10
It primarily relies on the pressure difference and centrifugal force. When a double-suction pump starts operating, negative-pressure zones are created at both of its inlets, causing liquid to be drawn from the supply system toward the pump's suction ports due to the pressure differential.
It primarily relies on the pressure difference and centrifugal force. When a double-suction pump starts operating, both of its inlets create negative-pressure zones, causing liquid to flow from the supply system toward the pump’s suction inlet due to this pressure differential. Once the liquid enters the pump cavity through the suction inlet, the pump’s rotor begins to rotate. The rotor typically consists of an impeller and a shaft, with the impeller playing a key role in transferring the liquid. As the rotor spins, it propels the liquid toward the pump’s discharge outlet. Simultaneously, the rotation of the rotor generates centrifugal force, which pushes the liquid outward and significantly increases its pressure. Finally, as the pressurized liquid reaches the discharge outlet, the pump efficiently delivers it into the connected pipeline or storage container.

The pump transfers mechanical energy from the prime mover or other external sources to the liquid, increasing its energy. It is primarily used to transport liquids such as water, oil, acidic and alkaline solutions, emulsions, suspensions, and even molten metals. Additionally, it can handle liquid-gas mixtures as well as fluids containing suspended solid particles.
Keep the equipment clean, dry, free of oil stains, and leak-proof. Regularly inspect the pump for operating sounds, vibrations, and any signs of leakage.
When selecting a water pump, consider the following key points.
Determine flow rate: Calculate the flow rate based on the specific requirements for water usage or liquid transport. Determine head: Compute the vertical height from the water source to the destination, accounting for friction losses in the pipeline.
Pumps are widely used in various fields.
Agricultural irrigation: Drawing groundwater or river water for irrigation purposes. Construction projects: Used for concrete delivery, building drainage, fire protection systems, and more. Industrial production: Transporting various liquids, such as oil, chemical raw materials, liquid ammonia, and more.
