3" IPRO 1-37 – 3" submersible pump with enhanced sand resistance, 400 V
The IPRO 3" IPRO 1-37 is a multistage, three-phase submersible pump with a diameter of 74 mm, designed for wells with a minimum internal diameter of 85 mm. Manufactured using Italian technology and offering enhanced sand resistance, it is intended for drawing and pumping untreated water from deep-water sources.
Who it is for
- Farms and horticultural operations with a three-phase power supply – powering irrigation systems: sprinklers and drip lines.
- Households with a private water source – drawing raw water from a deep well for further treatment and use.
- Installers – 400 V three-phase power supply, ready-to-use unit with a 20 m cable, plug, and built-in thermal protection.
- Well users with sandy water – enhanced sand resistance extends trouble-free operation.
Applications
- Drawing and pumping technically clean untreated water from drilled deep-water sources before treatment.
- Powering installations in households and farms from a private water source, where a three-phase power supply is available.
- Powering irrigation systems and drainage applications.
In narrow drilled wells, the 3" IPRO 1-37 400V submersible pump operates in a vertical or horizontal position; its 74 mm diameter allows installation in wells with an internal diameter of just 85 mm.
The pump is not a water treatment device and does not confirm that the water is suitable for consumption. If the water is to be used for drinking, cooking, or other household purposes, the user must ensure proper treatment and water quality control at the point of use.
Features of the 3" IPRO 1-37 pump – description and technical data
The 3" IPRO 1-37 is a multistage submersible pump with an oil-cooled three-phase motor and built-in thermal protection. Its enhanced sand resistance and Italian manufacturing technology ensure long, trouble-free operation in untreated water.
The water-contacting components are made of corrosion- and abrasion-resistant materials: the suction and discharge connections, housing, shaft, and rotor are made of AISI 304 stainless steel; the impeller is made of PPO; the diffuser is made of reinforced polycarbonate; the mechanical seal is ceramic / SiC / NBR; and the bearings are NSK. This material selection ensures durability in demanding well operating conditions.

Frequently asked questions (FAQ) – what is the 3" IPRO 1-37 submersible pump used for?
What is the 3" IPRO 1-37 submersible pump used for?
Application of the 3" IPRO 1-37 pump
The 3" IPRO 1-37 is used to draw and pump raw water from drilled deep-water intakes, including to supply properties with their own water intake and irrigation systems. Water drawn from the intake is intended for further treatment.
What distinguishes the 3" IPRO series?
Increased sand resistance
The 3" IPRO series features increased sand resistance and premium materials: AISI 304 stainless steel, a PPO impeller, a reinforced polycarbonate diffuser, and NSK bearings. The motor is oil-cooled and has built-in thermal protection.
What type of well is the 3" IPRO 1-37 pump suitable for?
Selecting the pump for the well diameter
The pump has a diameter of 74 mm and is intended for wells with a minimum internal diameter of 85 mm. It can operate vertically or horizontally, at an immersion depth of up to 100 m.
How does the 400 V version differ from the 230 V version?
400 V three-phase version
The 400 V version is three-phase powered (3~400 V) and intended for installations with access to a three-phase power supply. Three-phase power ensures smooth motor operation and lower current consumption per phase than the single-phase 230 V version.
