6" ISP 46-2 - submersible pump
The 6" ISP submersible pump is a multistage design by IBO, made entirely of stainless steel and intended for drawing and pumping untreated water in single- and multi-family homes, farms, and industrial installations. Lower-powered models have a 4" diameter, while models rated 7.5 kW and above use 6" motors, making it possible to select a drive suited to the specific operating point. Thermal protection built into the winding protects the motor against overload.
Who it's for
-
Owners of single- and multi-family homes – The series’ wide power range makes it possible to choose a model suited to the well depth and household water demand.
-
Farmers and fruit growers – Higher-rated models in the series supply extensive irrigation systems, sprinkler systems, and frost-protection installations over large areas.
-
Industrial plants and drainage installations – The all-stainless-steel construction is suitable for continuous operation and high flow rates.
-
Installers and well-drilling companies – The clear distinction between 4" and 6" motors makes it easier to select a drive for a specific model and installation conditions.
Applications
The 6" ISP series is designed to draw and pump clean, untreated water from deep drilled wells for single- and multi-family homes, farms, irrigation systems, and industrial and drainage installations. The pump does not treat water. If using it for other purposes, we recommend ensuring that the water is properly treated.
The pumps operate vertically in wells with a minimum internal diameter of 160 mm and a maximum pumped water temperature of 35°C. The 6" ISP 400 V submersible pump is compatible with standard pressure tanks and pressure control systems selected to suit the scale of the installation.
6" ISP Series Features
The 6" ISP series pumps are made entirely of AISI 304 stainless steel, from the suction and discharge body to the impeller and diffuser, providing corrosion resistance under typical operating conditions. The individual models differ in their operating points on the shared performance curve and in the diameter of the motor used.
Models rated up to 7.5 kW are equipped with a 4" motor, while models rated 7.5 kW and above use a more durable 6" motor. Thermal protection built into the winding protects the motor against overload, while oil cooling ensures stable continuous operation.

Frequently asked questions (FAQ) – 6" ISP submersible pump
What type of well is the 6" ISP submersible pump suitable for?
The pump is designed for wells with a minimum internal diameter of 160 mm. Before purchasing, check the actual borehole diameter to avoid installation problems or motor overheating.
What happens if the well runs out of water while the pump is running?
The pump must not run "dry" – a lack of water can cause overheating and damage to the motor, and such damage is not covered by the warranty. To prevent this, we recommend installing a dry-run protection device that monitors the water level in the well.
How does the 6" ISP pump differ from the 6" SD pump?
Both series have the same diameter and are designed for similar wells, but they differ in housing material – the 6" ISP is made entirely of stainless steel, while the 6" SD has a gray cast iron suction and discharge housing. The choice depends on whether maximum corrosion resistance (ISP) or a proven cast iron design (SD) is your priority.
How do I choose a 6" ISP pump to suit my needs?
Choosing a model depends on the well depth and the amount of water needed at one time – the series includes options with different head heights and flow rates, from modest household needs to large agricultural and industrial installations. W If you have any questions, please contact our technical department.
Where can you buy a 6" ISP submersible pump?
Dambat does not sell directly. 6" ISP series pumps are available from sales partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 6" ISP pump?
IBO – 24 months (2 years) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
