6" ISP 46-2 – submersible pump
The 6" ISP submersible pump is a multistage IBO design made entirely of stainless steel, intended for drawing and pumping raw water in single- 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 operating point. Thermal protection built into the winding protects the motor against overload.
Who is it for?
-
Owners of single- and multi-family homes – the wide power range in the series makes it possible to select a model according to the well depth and household water demand.
-
Farmers and fruit growers – the higher-output models in the series power extensive irrigation systems, sprinkler systems, and frost-protection installations across large areas.
-
Industrial plants and drainage installations – the fully 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 the specific model and installation conditions.
Application
The 6" ISP series is intended for drawing and pumping clean, technically raw water from drilled deep-water intakes for single- and multi-family homes, farms, irrigation systems, and industrial and drainage installations. The pump is not a water-treatment device – 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 equipment 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. Individual variants differ in their operating point on the shared 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 a more durable 6" motor is used from 7.5 kW upward. 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 intended for wells with a minimum internal diameter of 160 mm. Before purchasing, 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 operating?
The pump must not run “dry” – a lack of water may cause overheating and motor damage, and such a fault is not covered by the warranty. To prevent this, it is advisable to install 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 intended for similar wells, but they differ in the body material – the 6" ISP is made entirely of stainless steel, while the 6" SD has a suction and discharge body made of gray cast iron. The choice depends on whether maximum corrosion resistance (ISP) or a proven cast-iron construction (SD) is the priority.
How do I select a 6" ISP pump for my needs?
The model selection depends on the well depth and the amount of water needed at the same time – the series includes variants with different heads and capacities, from modest domestic needs to large agricultural and industrial installations. If you have any doubts, 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 trade partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 6" ISP pump?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
