Tormac Vertical Turbine Pumps can be single-stage or multistage in design with submerged impellers enabling the pump to be started without the requirement for priming. The operation of Vertical Turbine pumps is intended to be unaffected by significant variations in the level of the water. For increased flow requirements, these pumps come with the mixed flow or axial flow impellers. The line shaft bearing with either internal or external cooling supports the transmission shaft in the column pipes. These pumps can be used in applications with wet or dry pits. To prevent reverse rotation, a ratchet system is installed on the coupler.
