QDX 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 enter the ratating blade channel via the suction strainer,which forms the support base for the pump.Here the fluid moves radially from the centre outwards.Acquiring energy both in the form of pressure and increased speed.When it leaves the impeller the fluid is conveyed towards to 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 body: Cast-iron
Motor housing: Aluminum
Motor wire: Copper
Shaft: 45# steel
PUMP INSTALLATION AND APPLICATIONS
As portable electric drainage &irrigation devices.QDX series single-phase vertical submersible pumps with lover water input are widely suitable for water cluster boxes.Farmland.industrial&mining enterprises.construction sites.ship and family,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 3-phase asynchronous motor is equipped in this pump and installed with a built-in thermal protector,and can be automatically cut-off in the case of overheat or over-current.Thus assuring safe and reliable running under worse circumstances.
