4" SPINOX 8-21 (4 kW, 400 V) - multistage stainless steel deep well pump, IPRO water-filled motor
4" SPINOX with an IPRO water-filled motor is a multistage deep well pump with a diameter of 98 mm, made entirely of AISI 304 stainless steel and designed to draw and pump clean, untreated water from drilled deep wells with a minimum internal diameter of 115 mm. The pump is driven by an IPRO WMC water-filled motor. The series includes a range of models with different hydraulic parameters and a wide power range. This variety makes it possible to select the ideal model for unique needs.
Who it's for
-
Farms and businesses supplied by their own sources - field irrigation, drainage work, industrial uses - where any contact between the water and the motor's lubricating oil is immaterial.
-
Installers selecting pumps for various wells - several hydraulic versions and 230 V / 400 V options make it easier to match the model precisely to the well depth and the power supply available on site.
-
Holiday resorts and multi-family buildings - seasonal or year-round supply of utility water in locations without access to the municipal water network
-
Users upgrading their water systems - precise model gradations in terms of hydraulic parameters and dimensions make it possible to match the unit to the required conditions.
Applications
- Drawing and pumping raw water from drilled deep wells before treatment.
- Supplying households and farms with water from their own deep well.
- Industrial applications and drainage work requiring a pump with increased resistance to continuous operation.
Depending on the performance of the selected model, 4" SPINOX pumps with an IPRO water-cooled motor are ideal for both shallower domestic wells supplying a single household and deeper water intakes or installations serving several buildings simultaneously. The 4" SPINOX 8-21 submersible pump (4 kW, 400 V) with an IPRO water-cooled motor is selected individually to suit the parameters of the specific well - its depth, diameter and required output.
The 4" SPINOX pump is not a water treatment device and does not confirm
that the water is suitable for human consumption. If the water is to be used
for drinking, cooking or other domestic 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 water-filled motor is a multistage submersible pump in which all
key structural components – the suction and discharge bodies, housing, 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 contaminants. The mechanical seal is made of ceramic / SiC / NBR. The pump is factory-fitted with a check valve to prevent
water from flowing back through the discharge pipe after the pump stops.
It is driven by an IPRO WMC water-filled motor. The power cable length is selected
for the specific pump variant and well depth.
The operation of the 4" SPINOX pump can be upgraded with dry-run protection
that operates without the need to install additional probes or sensors in the well, and in systems
with two pumps supplying a shared system, they can be controlled alternately.
The pump operates continuously, in a vertical or horizontal position, at a maximum pumped liquid
temperature of 35°C and insulation class F.

Frequently asked questions (FAQ) - 4" SPINOX submersible pump with an IPRO water-filled motor
What is the 4" SPINOX submersible pump with an IPRO water-filled motor used for?
The 4" SPINOX with an IPRO water-filled motor is a multistage submersible pump designed to draw and pump raw / untreated water from drilled deep wells before treatment, including for supplying domestic systems and for agricultural and industrial applications.
How do I choose the right 4" SPINOX model for my well?
Model selection depends on the well’s depth and diameter, as well as the system’s required capacity. The range includes several hydraulic subcategories with different maximum capacities and power ratings.
What motors are available for the 4" SPINOX submersible pump?
The 4" SPINOX hydraulics are available with an IPRO WMC water-filled motor, an IPRO oil-filled motor, or an oil-filled motor from the Italian brand IBO Italy. The motor variant is selected individually, depending on the set ordered.
How can I protect the 4" SPINOX pump from running dry?
The pump can be used with dry-run protection that works without installing additional probes or sensors directly in the well, simplifying installation compared to solutions that require separate sensor wiring.
Where can I buy the 4" SPINOX submersible pump manufactured by Dambat?
Dambat does not sell directly. The 4" SPINOX pump is available from our business partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 4" SPINOX pump with an IPRO water-filled motor?
IPRO - 36 months (3 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
