4" SPINOX 14-28 (7.5 kW, 400 V) - multistage stainless steel submersible pump, IPRO oil-filled motor
The 4" SPINOX with an IPRO oil-filled motor is a multistage submersible pump with a diameter of 98 mm,
made entirely of AISI 304 stainless steel and designed to pump
clean raw water from drilled deep wells
with a minimum internal diameter of 115 mm. The pump is driven by an IPRO
oil-filled motor. The series includes a range of models with different hydraulic parameters
and a wide range of power ratings. This variety makes it possible to choose the ideal model for
unique needs.
Who it's for
-
Farms and businesses supplying systems from their own sources – field irrigation, drainage work, industrial purposes — where possible contact between the water and the motor’s lubricating oil is not a concern.
-
Installers selecting pumps for different types of wells – several hydraulic versions and 230 V / 400 V options make it easy to match the model precisely to the well depth and power supply available on the property.
-
Holiday resorts and multi-family properties – seasonal or year-round supply of utility water in locations without access to the municipal water network
-
Users modernizing their water systems – precise gradations between models in terms of hydraulic parameters and dimensions make it possible to match the device to the required conditions.
Applications
- Intake and pumping of raw water from drilled deep wells before treatment.
- Water supply for households and farms from their own deep well.
- Industrial applications and drainage work where a pump with increased resistance to continuous operation is required.
WDepending on the capacity of the selected model, 4" SPINOX pumps with an IPRO oil-filled motor
are ideal for shallower domestic wells supplying a single household, as well as deeper
wells or installations serving several buildings at once. The 4" SPINOX 14-28 submersible pump (7.5 kW, 400 V) with an IPRO oil-filled motor
is selected individually to suit the specifications of each well – its depth, diameter
and required capacity.
The 4" SPINOX pump is not a water treatment device and does not certify that the water is fit for human consumption – if the water is to be used for drinking, cooking, or other household purposes, an appropriate water treatment system and water quality monitoring at the point of use must be provided.
Features, description, and technical data
The 4" SPINOX with an IPRO oil-filled motor is a multistage deep-well pump in which all key structural components – the suction and discharge bodies, casing, shaft, impeller, and diffuser – are made of AISI 304 stainless steel. This design provides increased wear resistance and a long service life when operating in contact with raw water, which may contain fine mineral impurities. The mechanical seal is made of ceramic / SiC / NBR. The pump is factory-equipped with a check valve to prevent water from flowing back through the discharge pipe after the pump stops.
Powered by an IPRO oil-filled motor, cooled and lubricated by oil in a sealed motor chamber. The power cable length is selected for the specific device variant and well depth.

Frequently Asked Questions (FAQ) - 4" SPINOX deep-well pump with an IPRO oil-filled motor
What is the 4" SPINOX deep-well pump with an IPRO oil-filled motor used for?
The 4" SPINOX with an IPRO oil-filled motor is a multistage deep-well pump designed to
draw and pump raw / untreated water from drilled deep wells before
treatment - for example, to supply residential systems and for
agricultural and industrial applications.
How do I choose the right 4" SPINOX model for my well?
The model selection depends on the well's depth and diameter and the required system flow rate -
the series includes several hydraulic subcategories with different maximum flow rates and power ratings.
What motors are available for the 4" SPINOX deep-well pump?
The 4" SPINOX hydraulics are available with an IPRO oil-filled motor, an IPRO WMC
water-filled motor, or an Italian IPRO oil-filled motor - the motor type is selected
individually depending on the set being ordered.
How can I protect the 4" SPINOX pump from running dry?
The pump can be used with dry-run protection that works without
the need to install additional probes or sensors directly in the well, simplifying
installation compared to solutions that require separate sensor wiring.
Where can I buy a 4" SPINOX deep-well pump manufactured by Dambat?
Dambat does not sell directly. The 4" SPINOX pump is available from our
sales partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 4" SPINOX pump with an IPRO oil-filled motor?
IPRO - 36 months (3 years) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
