Description
NEPTUN 50/60 - submersible pump with float switch
NEPTUN is a series of multistage submersible pumps with a float switch from IBO, designed for dug wells. The motor's cooling jacket allows the pump to operate without being fully submerged or using a casing pipe, while the built-in float switch protects it from dry running. The pump is suitable for supplying buildings with water, as well as for watering and household tasks.
Who it's for
- Owners of dug wells – the pump's cooling jacket allows it to operate without being fully submerged or using a casing pipe.
- Homeowners and allotment gardeners – water for the home, garden watering and household tasks.
- Installers – the pump is ready to install straight out of the box, with a float switch and built-in capacitor.
- Owners of installations with a pressure tank – compatible with pressure tanks in domestic water pressure systems.
Applications
NEPTUN pumps are used primarily in ring wells to supply buildings with water, for irrigation and for household tasks. Thanks to the motor cooling jacket, the pump does not need to be fully submerged and does not require the casing pipe needed by conventional multistage pumps. The built-in float switch shuts off the pump when the water level is low, protecting it from dry running.
The pump works with a pressure tank to create a domestic pressurized water system. It pumps clean or slightly sandy water, with a sand content of up to 0.25 kg/m³. The NEPTUN 230 V submersible pump with float switch is ideal for everyday water supply at allotments and in households.
Features of the NEPTUN submersible pump
NEPTUN pumps are multistage submersible pumps with a float switch, designed for ring wells. A key feature of their design is the motor cooling jacket, which allows the pump to operate without being fully submerged and without a casing pipe. The float switch automatically shuts off the pump when the water level is too low, protecting the motor from dry running.
The motor has built-in thermal protection and a capacitor, so the pump does not require an external starter box and is ready to install straight out of the box. The housing, shaft and rotor are made of AISI 304 stainless steel, while the impeller and diffuser are made of PPO polymer. The mechanical seal uses a SiC/SiC/NBR configuration.
The series includes two models: NEPTUN 50/60 (head up to 50 m, flow rate up to 60 l/min) and NEPTUN 40/110 (up to 40 m and up to 110 l/min). Both models have a power rating of 0.5 kW, run on 230 V and operate continuously.

Frequently asked questions (FAQ) - IBO NEPTUN submersible pump with float switch
What is the NEPTUN pump used for?
The NEPTUN pump is a multistage submersible pump with a float switch, designed for ring wells. It is used to supply buildings with water, for watering, and for household tasks. It can operate in a system with a pressure tank.
How does NEPTUN differ from a conventional multistage pump?
The NEPTUN has a motor cooling jacket, so it does not need to be fully submerged and does not require a protective pipe. Conventional multistage pumps usually require this type of protection and must operate fully submerged. This makes installation in a ring well easier.
Which NEPTUN model should I choose - 50/60 or 40/110?
The NEPTUN 50/60 can pump water to a greater height - up to 50 m, at a flow rate of up to 60 l/min. The NEPTUN 40/110 delivers a higher flow rate - up to 110 l/min, with a pumping height of up to 40 m. Choose the higher-head model for deeper water sources, and the higher-flow model when water volume is a priority.
Is the pump protected against running dry?
Yes. The built-in float switch turns off the pump if the water level drops too low, protecting the motor from running dry. The motor also has thermal protection built into the winding.
Does NEPTUN work with a pressure tank?
Yes. NEPTUN pumps can be installed with a pressure tank to create a domestic pressure-boosting system. The tank reduces how often the pump switches on and stabilizes the pressure in the system.
Where can I buy the IBO NEPTUN pump?
As a manufacturer, we do not sell directly. The IBO NEPTUN submersible pump with float switch is available from our business partners, plumbing wholesalers, and authorized online distributors. The model is selected based on the well depth and water demand.
What is the warranty on the IBO NEPTUN pump?
IBO - 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat. For help choosing a model, contact an authorized distributor.
