WORKING PRINCIPLE

SPA pumps are half open impeller centrifugal submersible pumps, designed for automatic and non-automatic use, the impeller mounted on the end of the drive shaft, consists of a rear disk and blades, which are enclosed by the pump body cover. Fluid enters the rotating blade channel via the suction strainer, which forms the support base for he pump. Here the fluid moves radially from the centre outwards, acquiring energy in the form of pressure and increased speed. When it leaves the impeller, the fluid is conveyed towards the volute, here part of the kinetic energy is transformed into pressure energy and the fluid leaves the pump via the side opening machined in the pump body.
