Description
NEPTUN 40/110 - submersible pump with a float switch
NEPTUN is a series of IBO multistage submersible pumps with a float switch, designed for ring wells. The motor cooling jacket allows the pump to operate without being fully submerged and without a riser pipe, while the built-in float switch protects it from running dry. The pump is suitable for supplying buildings with water, irrigation and household tasks.
Who is it for?
- Owners of ring wells – the pump with a cooling jacket operates without being fully submerged and without a riser pipe.
- Homeowners and allotment gardeners – water for the home, garden irrigation and household tasks.
- Installers – ready to install straight out of the box, with a float switch and built-in capacitor.
- Owners of systems with a pressure tank – works with a pressure tank in a domestic pressurized water system.
Applications
NEPTUN pumps are used primarily in ring wells to supply buildings with water, water gardens and carry out household tasks. Thanks to the motor cooling jacket, the pump does not need to be fully submerged and does not require a riser pipe, which conventional multistage pumps need. The built-in float switch turns off the pump when the water level is low, protecting it from running dry.
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 a float switch is ideal for everyday water supply at allotments and in homes.
NEPTUN submersible pump features
NEPTUN pumps are multistage submersible pumps with a float switch, designed for ring wells. A key design feature is the motor cooling jacket, which allows the pump to operate without being fully submerged and without a riser pipe. The float switch automatically turns off the pump when the water level is too low, protecting the motor from running dry.
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 (lifting height 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 are designed for continuous operation.

Frequently asked questions (FAQ) – NEPTUN IBO submersible pump with float
What is the NEPTUN pump used for?
The NEPTUN pump is a multistage submersible pump with a float, designed for ring wells. It supplies buildings with water and is used for watering and household tasks. It can operate as part of a system with a pressure tank.
How is NEPTUN different from a conventional multistage pump?
NEPTUN has a motor cooling jacket, so it does not need to be fully submerged or require a protective pipe. Conventional multistage pumps usually need this kind 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 pumps water to a greater height – up to 50 m, at a flow rate of up to 60 l/min. The NEPTUN 40/110 provides a higher flow rate – up to 110 l/min, with a head of up to 40 m. Choose the higher-head model for deeper wells, and the higher-flow model where water volume is the priority.
Is the pump protected against dry running?
Yes. The built-in float switch turns the pump off when the water level drops too low, protecting the motor from dry running. The motor also has thermal protection built into the winding.
Is NEPTUN compatible with a pressure tank?
Yes. NEPTUN pumps can be installed with a pressure tank to create a domestic water pressure boosting system. The tank reduces how often the pump switches on and stabilizes the pressure in the system.
Where can I buy the NEPTUN IBO pump?
As the 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. Choose a model based on the well depth and water demand.
What is the warranty on the NEPTUN IBO 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.
