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.

PUMP INSTALLATION AND APPLICATIONS

As portable electric drainage & irrigation devices, SPA series single phase vertical submersible pumps with lower water input are widely suitable for water cluster boxes, farmland, industrial & mining enterprises, construction sites, ship and farmily, and characterized by less volume, light weight and convenient operation etc. (The pump is fitted with a floating switch, so it is possible to achieve the automatic control of start-stop action under no one?s care.) single phase capacitor running asynchronous or three phase asynchronous motor is equipped in this pump and installed with a built in heat protector, and can be automatically cut-off in the case of overheat or overcurrent, thus assuring safe and reliable running under worse circumstances.
