  • Horsepower

    Horsepower indicates the kinetic power of the pump. Higher horsepower means more efficiency in water pumping, affecting the flow (l/h) and the head (m).

  • Voltage

    Single-Phase

    Single-phase power supply refers to the provision of electrical energy from single-phase current (e.g., 230V AC), which is the most common type of supply for residential and small commercial applications. 

  • Power

    It is the energy consumed by the motor to pump water. The greater the power, the more effectively it can lift and move water, especially over long distances or heights.

  • Manometric Height

    45

    The Maximum Head Height refers to the maximum height at which the pump can lift water against resistance (such as pipes or filters). As the head height increases, the pump's flow rate decreases.

    • The maximum head height is considered by manufacturers to be the point where the water will just barely reach.
    • The maximum performance is considered by manufacturers to be the water flow at 0-1 meter head height.

Cable Length
20 m

Features

Electronic Level Sensor
No

Electronic Level Sensor

It automatically activates the pump without the classic hanging float switch. It is ideal for narrow spaces and pits, as there is no risk of it getting stuck anywhere and flooding the area.
with Cutter Impeller
No

with Cutter Impeller

Components that chop, "cut" solid materials, such as organic waste or other particles, before they pass into the pump. They are mainly used in sewage or dirty water pumps, preventing clogging or damage to the system.
Float switch
No

Float switch

It is a mechanism that automatically controls the operation of the pump. When the water level reaches a predetermined height, the float activates the pump.
Vortex
No

Vortex

The vortex system in submersible water pumps uses vortex technology to create a rotating water current, which helps in the efficient transfer of water, even when it contains particles or solids.

Maximum Head Height: 45


The Maximum Head Height refers to the maximum height at which the pump can lift water against resistance (such as pipes or filters). As the head height increases, the pump's flow rate decreases.

  • The maximum head height is considered by manufacturers to be the point where the water will just barely reach.
  • The maximum performance is considered by manufacturers to be the water flow at 0-1 meter head height.
Maximum Particle Size
5 mm

Maximum Particle Size

Specifies the largest size of solid particles (such as sand, stones, or other impurities) that the device can pump without clogging or being damaged.
Shallow Suction
No

Shallow Suction

This function allows the pump to suck water from an extremely low level (up to 1-3 mm), ideal for flooded floors and basements.
