Description
CVI INOX 15-5 T – vertical industrial stainless-steel centrifugal pump
The IPRO CVI 15-5 T INOX is a vertical, multistage centrifugal pump with in-line connections, designed for precise operating-point selection in systems requiring consistent performance and low noise levels. The impeller, diffuser, and all hydraulic components that come into contact with the medium are made of AISI 304 stainless steel, while the IE3 efficiency-class three-phase motor complies with current energy-efficiency requirements for industrial drives. The in-line design allows installation directly along the pipeline axis without the need to redesign the system.
Who is it for
- Large commercial buildings, hotels, and hospitals – a flow rate of approximately 250 l/min makes it possible to supply large public facilities with water.
- Installers of large pressure-boosting systems – the pump works as a primary or auxiliary unit in larger pressure-boosting stations.
- Medium-sized and large industrial plants – cooling circuits and boiler room supply in facilities with increased process water requirements.
- Fire protection systems for medium-sized facilities – high head and stable flow support sprinkler systems and indoor hydrants.
Applications
The IPRO CVI 15-5 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems for large facilities such as hotels, hospitals, and office buildings. In industrial environments, it performs well in high-pressure circulation systems, air-conditioning and refrigeration systems, and fire protection systems.
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 variant requires considering the NPSH characteristics of the suction system to avoid the risk of cavitation. The CVI 15-5 T INOX industrial pump operates in a three-phase system.
Features of the CVI 15-5 T INOX – design and technical specifications
The CVI 15-5 T INOX pump is constructed with materials precisely selected according to the function of each component. The pump head and base, as load-bearing components without 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 in contact with the medium—the inlet, outlet, impeller, diffuser, pump casing, discharge port, and cover—are made of AISI 304 stainless steel. The neck ring is made of PTFE, while the O-ring seals are made of EPDM/FKM. The mechanical cartridge seal (silicon carbide / tungsten carbide / EPDM) is designed to operate within a range of 10–90°C.
The motors driving the CVI 15-5 T INOX cover a power range from 3 to 11 kW, depending on the selected head variant, and belong to the IE3 efficiency class, in accordance with the EU ecodesign regulation. The flanged connection is DN50.

Frequently asked questions (FAQ) – CVI 15-5 T INOX vertical pump
What industrial applications is the CVI 15-5 T INOX pump suitable for?
The IPRO CVI 15-5 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 15-5 T INOX pump made of cast iron if it is an "INOX" pump?
The INOX designation applies to the components that come into 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, ensuring adequate structural rigidity.
What is the IE3 efficiency class, and why does it matter when selecting a pump?
IE3 is the energy efficiency class for electric motors established by the EU Ecodesign Regulation. Higher efficiency translates into lower operating costs during continuous operation, which is particularly important in industrial installations operating in S1 mode.
What liquid can the CVI 15-5 T INOX pump handle?
The pump is designed for chemically non-aggressive clean liquids with temperatures ranging from -20°C to 90°C (up to 104°C on special order) and a pH range of 3–9.
What capacity does the CVI 15-5 T pump offer?
At the beginning of the designation of each model in the series, there is a number corresponding to the pump's nominal capacity class—in the case of the CVI 15-5 T, this is 15 m³/h, or approximately 250 l/min. This flow rate is sufficient for large commercial buildings, hotels, and hospitals, as well as medium-sized industrial plants, although it still does not match the scale of large manufacturing facilities or main water supply networks.
