Description
CVI INOX 15-4 T – vertical industrial stainless steel centrifugal pump
The IPRO CVI 15-4 T INOX is a vertical, multistage centrifugal pump with an in-line port configuration, designed for precise operating-point selection in systems requiring consistent performance and low noise levels. The impeller, diffuser, and all hydraulic components in contact with the medium 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 system.
Who it’s for
- Large commercial buildings, hotels, and hospitals – a flow rate of around 250 l/min can supply large public buildings with water.
- Installers of large pressure booster sets – the pump is suitable as a base or booster unit in larger pressure boosting stations.
- Medium and large industrial plants – cooling circuits and boiler room supply in plants with higher process water demand.
- Fire protection systems in medium-sized facilities – high head and stable flow support sprinkler systems and indoor fire hydrants.
Applications
The IPRO CVI 15-4 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems in large facilities such as hotels, hospitals, and office buildings. W In industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, and fire protection systems.
W In industry, the pump is used to supply boiler rooms and in machine lubrication and cooling systems, while in agriculture it is used to irrigate large areas. Selecting the right model requires taking the NPSH characteristics of the suction system into account to avoid the risk of cavitation. The CVI 15-4 T INOX industrial pump operates on a three-phase power supply.
CVI 15-4 T INOX features – design and technical specifications
The CVI 15-4 T INOX pump is designed with materials precisely selected 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 at 10–90°C.
The motors powering the CVI 15-4 T INOX cover a power range of 3 to 11 kW, depending on the selected head variant, and belong to efficiency class IE3, in accordance with the EU ecodesign regulation. The flanged connection is DN50.

Frequently asked questions (FAQ) - CVI 15-4 T INOX vertical pump
What industrial applications is the CVI 15-4 T INOX pump suitable for?
The IPRO CVI 15-4 T INOX pump is used in high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, boiler room supply systems and domestic water supply systems.
Why are the head and base of the CVI 15-4 T INOX pump made of cast iron if it is an "INOX" pump?
The INOX designation applies to the parts in direct contact with the pumped medium - the impeller, diffuser, casing, 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, which provides the required structural rigidity.
What is the IE3 efficiency class, and why does it matter when choosing 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 15-4 T INOX pump?
The pump is designed for clean, chemically non-aggressive liquids with a temperature of -20°C to 90°C (up to 104°C on special order) and a pH range of 3–9.
What capacity does the CVI 15-4 T pump offer?
The number at the beginning of each model designation in the series indicates the pump's nominal capacity class - for the CVI 15-4 T, this is 15 m³/h, or about 250 l/min. This flow rate is suitable for large commercial buildings, hotels and hospitals, as well as medium-sized industrial plants, although it still falls short of the scale required by large production facilities or main water supply networks.
