VX 20/50-ST - 2 HP three-phase VORTEX electric pump for waste water
Flow rate up to 700 l/min (42 m³/h). Head up to 15 m. 1.5 Kw (2 HP) motor.
The Pedrollo VX 20/50-ST submersible electric pump is designed to create a powerful, robust, high-efficiency pump made entirely of stainless steel.
This electric pump is designed to be used in the domestic, civil and industrial sectors.
The use of the VX 20/50-ST is recommended for draining flooded areas such as cellars, underground car parks, car wash areas, for emptying cesspits and for disposing of sewage.
The hydraulic geometry of the volute and the VORTEX impeller allow for maintaining high efficiency in terms of performance and consequently significant energy savings.
The VORTEX impeller of the VX 20/50-ST allows the pumping of solids with a diameter of up to 50 millimetres and, thanks to its special geometry, guarantees safe operation against clogging.
It can be used up to 5 meters below water level.
The pump comes with a 10 meter power cable.
The flow rate ranges from 50 to 700 liters per minute. The head ranges from 3 to 15 meters.
The VX 20/50-ST must be powered by a three-phase voltage, has a horsepower of 2 HP and the temperature of the liquid to be pumped ranges from -10 degrees centigrade up to +40.
