Vertical turbine (VT) pumps are a type of centrifugal pump used in wastewater to pull water vertically from a source underneath the ground. Whether the source of water sits tens, hundreds, or thousands of feet deep underground, vertical pumps offer versatile applications for wastewater treatment. Being that they are extremely space-efficient due to their design, it allows them to be inserted into pre-existing structures, and they simply don’t take up as much space on the surface as other pumps.
VT pumps are meticulously designed to efficiently lift and transfer water from submerged sources such as wells or reservoirs. Their vertical orientation allows for submerged operation, eliminating the need for priming. The central component of these pumps is the impeller, which rotates to create a low-pressure zone, drawing water into the pump and imparting kinetic energy to lift it upwards. Intake structures at the bottom of the pump prevent debris from entering while facilitating the flow of water.

Most VT pumps have more than one impeller to increase the amount of head the pump can produce without changing the flow rate. Because the water is flowing upwards, increasing the head of the pump, which is the maximum height at which water can be pumped against gravity, will therefore lengthen how deep underground the pump can extend. The more impellers the pump; the more head the pump can produce.
These pumps are essential for discharging treated wastewater (effluent) from the treatment plant. Whether the effluent is discharged into receiving water bodies or reused for irrigation or industrial purposes, these pumps play a crucial role in ensuring the safe and efficient transfer of treated water to its intended destination. Their reliability and robust design make them well-suited for continuous operation in demanding wastewater treatment environments.
