6" ISP 17-11 - submersible pump
The 6" ISP submersible pump is a multistage IBO pump made entirely of stainless steel, designed to draw and pump untreated water for single-family and multi-family homes, farms, and industrial installations. Lower-power models have a 4" diameter, while models rated 7.5 kW and above use 6" motors, allowing you 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-family and multi-family homes – the series' wide power range makes it possible to choose a model to suit the well depth and household water demand.
-
Farmers and orchard growers – higher-powered models in the series supply extensive irrigation systems, sprinkler systems, and frost protection installations across large areas.
-
Industrial plants and drainage installations – the all-stainless-steel construction is well suited to continuous operation and high flow rates.
-
Installers and well-drilling companies – the clear distinction between 4" and 6" motors makes it easy to choose the right drive for a specific model and installation conditions.
Applications
The 6" ISP series is designed to draw and pump clean, untreated water from drilled deep wells for single-family 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 appropriate water treatment.
The pumps operate vertically in wells with a minimum internal diameter of 160 mm, at a maximum pumped water temperature of 35°C. The 6" ISP 400 V submersible pump is compatible with standard pressure tanks and pressure controls selected to suit the scale of the installation.
Features of the 6" ISP Series
The 6" ISP series pumps are made entirely of AISI 304 stainless steel – from the suction and discharge casing to the impeller and diffuser – providing corrosion resistance under typical operating conditions. The individual variants differ in their operating point on the shared performance curve and in the diameter of the motor used.
Models with power ratings up to 7.5 kW are equipped with a 4" motor, while models rated 7.5 kW and above use a more robust 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 buying, it is worth checking 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, it is worth installing dry-run protection that monitors the water level in the well.
What is the difference between the 6" ISP pump and the 6" SD pump?
Both series have the same diameter and are designed for similar wells, but they differ in the material of the pump body – the 6" ISP is made entirely of stainless steel, while the 6" SD has a gray cast iron suction-discharge body. 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?
The model you choose depends on the well depth and the amount of water needed at any one time – the series includes versions with different delivery heads 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 I 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?
