ISQ 40-750 – submersible pump with float switch
The IBO ISQ submersible pump is a stainless steel device with a float switch, designed for pumping technically clean and slightly contaminated water without abrasive particles such as sand. Its slim steel housing allows installation in small sumps.
Who it is for
-
Homeowners and landowners – the built-in float switch automates pump operation without additional control equipment.
-
Installation and service companies – the slim steel housing allows installation in small sumps.
-
Rainwater harvesting system users – the pump works well for supplying systems with rainwater.
-
Fish farms and livestock farms – the pump is suitable for use in fish farms and for pumping water from ponds and tanks.
Applications
The ISQ submersible pump with float switch is designed for pumping technically clean and slightly contaminated water without abrasive particles such as sand. It is suitable for pumping rainwater and surface water from ponds, lakes, and rivers, supplying garden ponds, and draining flooded rooms, houses, garages, and commercial premises. The pump is not a water treatment device – when using it for other purposes, we recommend ensuring appropriate water treatment.
The device operates in a vertical position and tolerates water with a pH range of 6.5–8.5, with a maximum pumped liquid temperature of 50°C. The minimum immersion depth of the pump with the float switch is 25 cm, allowing the float to move freely.
Features of the ISQ pump with float switch
The pump is made of AISI 304 stainless steel – motor housing, shaft, rotor, and impeller – making it resistant to corrosion during continuous contact with water. The cooling jacket allows the pump to operate without being fully submerged in water.
The built-in float switch automatically controls pump operation according to the water level and provides basic protection against dry running. Thermal protection built into the motor winding protects the pump from overheating.

Frequently asked questions (FAQ) – ISQ submersible pump with float switch
What type of water is the ISQ pump designed for?
The pump is designed for technically clean and slightly contaminated water without abrasive particles such as sand. The permissible solid particle size is 10 mm in series 32 and 40 mm in series 40.
What is the narrowest sump suitable for the ISQ pump?
The slim stainless steel housing allows installation in narrower sumps than pumps with a more bulky design, while the minimum immersion depth of 25 cm ensures free movement of the float.
How does the pump protect against dry running?
Protection is provided by the built-in float switch, which cuts off power to the motor when the water level drops below the safe minimum. In addition, thermal protection in the winding protects the motor from overheating.
How do I choose the right ISQ pump model for my needs?
The choice of model depends on the required head and flow rate – the series includes variants from 250 W (ISQ 32-330) to 1.1 kW (ISQ 50-1500), with three connection diameter classes: 32, 40, and 50. If in doubt, we encourage you to contact the technical department.
Where can I buy an ISQ submersible pump?
Dambat does not sell directly to consumers. ISQ pumps are available from trading partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the ISQ pump?
IBO – 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
