6" ISP 30-7 – submersible pump
The 6" ISP submersible pump is a multistage IBO construction made entirely of stainless steel, designed for drawing and pumping raw water in single-family and multi-family homes, farms, and industrial installations. Lower-power motors have a diameter of 4", while 6" motors are used from 7.5 kW upward, making it possible to select a drive suitable for the specific duty point. Thermal protection built into the winding protects the motor against overload.
Who it is for
-
Owners of single-family and multi-family homes – the wide power range in the series makes it possible to select a model according to well depth and household water demand.
-
Farmers and fruit growers – the higher models in the series supply extensive irrigation systems, sprinkler systems, and frost-protection installations over large areas.
-
Industrial plants and dewatering installations – the all-stainless-steel construction is suitable for continuous operation and high capacities.
-
Installers and well-drilling companies – the clear division into 4" and 6" motors makes it easier to select the drive for a specific model and installation conditions.
Applications
The 6" ISP series is designed for drawing and pumping technically clean raw water from drilled deep-water wells for single-family and multi-family homes, farms, irrigation systems, and industrial and dewatering installations. The pump does not treat water – when using it for other purposes, we recommend ensuring appropriate water preparation.
The pumps operate in a vertical position, 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 works with standard hydrophore tanks and pressure-control systems selected according to 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 body to the impeller and diffuser – providing corrosion resistance under typical operating conditions. The individual variants differ in their duty point on the common performance curve and in the diameter of the motor used.
Models with power up to 7.5 kW are equipped with a 4" motor, while from 7.5 kW upward a more durable 6" motor is used. Thermal protection built into the winding protects the motor against overload, while oil cooling ensures stable operation in continuous-duty mode.

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, it is worth checking the actual diameter of the borehole to avoid installation problems or motor overheating.
What happens if the well runs out of water while the pump is operating?
The pump must not run “dry” – lack of water may cause overheating and motor damage, and such a fault 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 body material – the 6" ISP is made entirely of stainless steel, while the 6" SD has a gray cast-iron suction-and-discharge body. The choice depends on whether maximum corrosion resistance (ISP) or a proven cast-iron construction (SD) is the priority.
How do I choose a 6" ISP pump for my needs?
The model choice depends on the well depth and the amount of water needed simultaneously – the series includes variants with different heads and capacities, from modest household needs to large agricultural and industrial installations. If in doubt, we encourage you to contact the technical department.
Where can I buy a 6" ISP submersible pump?
Dambat does not sell directly. Pumps from the 6" ISP series are available from commercial partners, plumbing wholesalers, and authorized online distributors.
What warranty conditions apply to the 6" ISP pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
