What Is a Floating Pump?

The floating pump is a specific multistage centrifugal pump working underwater. It uses the motor to rotate, and the resulting centrifugal force lifts the water or oil to the ground. This type of pump is widely used in farmland irrigation and oil exploitation. Due to the unique working environment, ESP has high requirements on its structure and performance, and many scholars have devoted themselves to the improvement of ESP performance [1,2].

The most important factor affecting the pump’s output is the available head. The higher the available head, the more the pump can deliver. Several factors influence the available head, including the NPSHa (available net positive suction head) and NPSHr (required net positive suction head). Ideally, you want NPSHa > NPSHr. Without enough net positive suction head, the pump will cavitate. Cavitation decreases the pump’s efficiency and shortens the pump’s life.

Floating fire pumps meet the rugged demands of forestry services and are also used for marine service, dewatering, pool maintenance, environmental clean-up and irrigation. They are particularly useful in environments where access to a pump is limited by the size of the water opening.

Modular pontoons with heavy pumping equipment can be easily assembled and disassembled. This allows easy onsite modifications for the operation of various water transfer applications. This also makes them ideal for sludge pumping in mining operations where the ability to easily move the pumps between ponds is critical. The modular design also allows for easier inspection, servicing, and monitoring.
