6" ISP 46-10 - submersible pump
The 6" ISP submersible pump is a multistage IBO model made entirely of stainless steel, designed for drawing and pumping untreated water in single-family and multifamily homes, farms, and industrial installations. Lower-powered motors have a 4" diameter, while models rated at 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 from overload.
Who it’s for
-
Owners of single-family and multifamily homes – the series’ wide power range makes it possible to select a model suited to the well depth and household water demand.
-
Farmers and orchardists – higher-powered models in the series supply extensive irrigation systems, sprinklers, and frost-protection systems 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 easier to select a drive for a specific model and installation conditions.
Applications
The 6" ISP series is designed for drawing and pumping clean, untreated water from deep drilled wells for use in single-family and multifamily 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 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 size of the installation.
Features of the 6" ISP series
6" ISP series pumps are made entirely of AISI 304 stainless steel – from the suction-discharge body to the impeller and diffuser, ensuring corrosion resistance under typical operating conditions. Individual variants differ in their operating point on the shared performance curve and in the diameter of the motor used.
Models with a power rating of up to 7.5 kW are equipped with a 4" motor, while models rated at 7.5 kW and above use a more robust 6" motor. Thermal protection built into the winding protects the motor from 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" – lack of water can cause the motor to overheat and become damaged, 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.
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 casing material – the 6" ISP is made entirely of stainless steel, while the 6" SD has a suction and discharge casing made of gray cast iron. 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 a time – the series includes options with different head heights and flow rates, from modest household needs to large agricultural and industrial installations. We encourage you to contact our technical department if you have any questions.
Where can I buy a 6" ISP submersible pump?
Dambat does not sell directly. 6" ISP series pumps are available from our sales partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 6" ISP pump?
IBO – 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
