  • Outlet: 1"
  • Performance: 5500lit/h
  • Power: 1200W

  • 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

    54

    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.

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"

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.

Maximum Output
5 m³/h

Maximum Output

The maximum output or flow of a submersible water pump, as defined by the manufacturers, is the maximum amount of water the pump can move under ideal conditions, usually with zero head (i.e., no lift resistance).
Pump Submersion Depth
10 m
Maximum Particle Size
1.5 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.

    This review is about the power: 1012.5 W

    I bought it 2-3 years ago, I don't remember. I installed it yesterday. Pressure that kills, amazing. It has a slight delay in response, about 1 second. The previous one I had didn't even have half the pressure and even though it claimed to be stainless steel, it rusted in 1 year. I won't mention the brand for obvious reasons. I highly recommend Nakayama.

    It works excellently in the water tank and supplies taps in various points of the estate. I haven't measured the consumption on standby, I will measure it and get back to you.
