Description
CVI INOX 3-15 T – vertical multistage stainless steel centrifugal pump, in-line design
The IPRO CVI 3-15 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed for precise selection of the operating point in installations requiring consistent performance and low noise levels. The impeller, diffuser, and all hydraulic components in contact with the fluid are made of AISI 304 stainless steel, while the IE3 efficiency class three-phase motor meets current energy efficiency requirements for industrial drives. The in-line design allows installation directly in the pipeline axis, without the need to redesign the installation.
Who it’s for
- Industrial and manufacturing plants – the CVI 3-15 T INOX pump provides stable pressure in high-pressure circulation systems, cleaning systems, and boiler room supply installations.
- Small and medium-sized apartment buildings – the multistage design provides high head at a flow rate sufficient for several to a dozen or so apartments or a small commercial building.
- Maintenance departments – the in-line design makes it easier to replace the pump without dismantling an entire section of the installation, reducing downtime.
- Fire protection and air conditioning system installers – the pump is suitable for fire protection, refrigeration, and air conditioning systems that require continuous, reliable operation.
Applications
The IPRO CVI 3-15 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems, including water supply networks, pressure boosting stations, and pressure boosting sets. W industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, and transferring oil, glycol, and coolant. It is also used to supply boiler rooms and in machine lubrication systems.
W agriculture, the pump serves irrigation systems and sprinkler installations, while in the services sector it is used in laundries and car washes. Selecting the right variant requires taking into account the NPSH characteristics of the suction system to avoid the risk of cavitation when operating near the maximum capacity point. The CVI 3-15 T INOX industrial pump operates in a three-phase system, powered by 3~230 V or 3~400 V.
CVI 3-15 T INOX features – design and technical data
The CVI 3-15 T INOX pump design is based on the precise allocation of materials according to the function of each component. The pump head and base, as load-bearing components that do not come into direct contact with the pumped medium, are made of ASTM25B cast iron, ensuring structural rigidity. The pump shaft is made of AISI 431 stainless steel, selected for its high mechanical strength. All hydraulic components that come into contact with the medium - inlet, outlet, impeller, diffuser, pump casing, discharge port, and cover - are made of AISI 304 stainless steel. The neck ring is made of PTFE, and the O-ring seals are made of EPDM/FKM. The cartridge mechanical seal (silicon carbide / tungsten carbide / EPDM) is designed for operation in the 10–90°C range.
The motors driving the CVI 3-15 T INOX belong to efficiency class IE3, in accordance with the EU ecodesign regulation for electric motors. Efficiency and the cos φ power factor increase with motor power, affecting the selection of electrical protection devices and power supply cable cross-sections.

Frequently asked questions (FAQ) – CVI 3-15 T INOX vertical pump
What industrial applications is the CVI 3-15 T INOX pump suitable for?
The IPRO CVI 3-15 T INOX pump is used in high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, boiler room supply, and domestic water supply systems.
Why are the head and base of the CVI 3-15 T INOX pump made of cast iron if it is an "INOX" pump?
The INOX designation applies to parts that come into direct contact with the pumped medium – the impeller, diffuser, housing, inlet, and outlet – which are made of AISI 304 stainless steel. The pump head and base provide structural support and do not come into contact with the liquid, so they are made of ASTM25B cast iron to ensure the structure is sufficiently rigid.
What is the IE3 efficiency class, and why does it matter when selecting a pump?
IE3 is an energy efficiency class for electric motors, as defined by the EU Ecodesign Regulation. Higher efficiency means lower operating costs during continuous operation, which is especially important in industrial installations operating in S1 mode.
What liquids can the CVI 3-15 T INOX pump?
The pump is designed for clean, chemically non-aggressive liquids with a temperature ranging from -20°C to 90°C (up to 104°C by special order) and a pH between 3 and 9.
What is the capacity of the CVI 3-15 T pump?
The number at the beginning of each model in the series indicates the pump's nominal capacity class – for the CVI 3-15 T, this is 3 m³/h, or approximately 50 l/min. This flow rate is suitable for small and medium-sized multi-unit residential buildings, smaller commercial properties, and moderate industrial systems, though it is still not sufficient for large manufacturing plants or tall multi-unit buildings.
