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.

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
Yes

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.
Outlet Nozzle
1 1/4"

Outlet Nozzle

The outlet nozzle refers to the point or the external diameter of the pump from which the pumped water or liquid exits. It is an important feature for determining the connection of the pump with the piping system and affects the flow capacity of the liquid.
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.

Pump Submersion Depth
10 m
Maximum Particle Size
10 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.
