NEMO - submersible diaphragm pump
The NEMO submersible diaphragm pump from IBO is a compact device using electromagnetic drive, designed for pumping technically clean water in locations requiring high discharge pressure with low power consumption. Its small diameter allows installation in narrow drilled wells, while its impeller-free design is suitable where lifting height is the primary consideration rather than capacity.
Who it is for
-
Installation and service companies – a mobile, compact device for emergency emptying of tanks, swimming pools, and flooded rooms.
-
Farms and horticultural facilities – high discharge pressure with low power consumption is suitable for watering from narrow boreholes.
-
Homeowners and allotment holders – the compact diameter allows installation in drilled wells with a minimum diameter of 120 mm.
-
Wholesalers and technical stores – the model expands the range with a compact high-pressure pump for applications where traditional deep-well pumps do not fit.
Application
The NEMO submersible diaphragm pump is designed exclusively for pumping technically clean water free of solid contaminants and abrasive particles such as sand or silt. The pump is intended for draining flooded rooms, emptying swimming pools and tanks, and supplying small irrigation systems from narrow-diameter drilled wells. The pump is not a water-treatment device – when using it for other purposes, we recommend ensuring appropriate water preparation.
The device operates in a vertical or horizontal position, at a maximum pumped-liquid temperature of 35°C, in wells with a minimum internal diameter of 120 mm. The NEMO 230 V submersible diaphragm pump generates high discharge pressure, making it suitable for systems requiring a high lifting height with low capacity.
NEMO pump features
The NEMO pump uses electromagnetic drive based on a diaphragm, enabling it to generate high discharge pressure with relatively low power consumption of 250 W. The aluminum housing protects the drive system and supports heat dissipation.
The pump is not designed for continuous operation – the maximum uninterrupted operating time is 60 minutes, after which a break is required to allow the device to cool down. The device does not have a built-in float switch or level sensor, so pump operation at low submersion must be monitored directly to prevent dry running.

Frequently asked questions (FAQ) – NEMO submersible diaphragm pump
What type of water can the NEMO pump handle?
The NEMO pump is designed exclusively for technically clean water free of solid contaminants and abrasive particles such as sand, gravel, or silt. Pumping sandy water will damage the diaphragm.
How long can the NEMO pump operate continuously?
The maximum uninterrupted operating time is 60 minutes, after which the device requires an approximately 20-minute break to cool down. The pump is not designed for continuous operation.
Does the NEMO pump have dry-running protection?
No – the NEMO pump does not have a built-in float switch or level sensor. Pump operation at low submersion must be monitored directly, and if the suction outlet emerges from the water, the power supply must be disconnected immediately.
How does the NEMO pump differ from the VM 60, and how should you choose the right model?
The NEMO pump achieves a greater lifting height (Hmax 80 m) with slightly lower current consumption, while the VM 60 has a lower lifting height (Hmax 60 m) with slightly higher capacity and current consumption. The choice depends on the depth to which the water needs to be lifted. If in doubt, we encourage you to contact the technical department.
Where can the NEMO submersible diaphragm pump be purchased?
Dambat does not sell directly. The NEMO pump is available from commercial partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the NEMO pump?
IBO – 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
