Description
CVI INOX 1-8 T – vertical multistage centrifugal pump made of stainless steel, in-line design
The IPRO CVI 1-8 T INOX is a vertical, multistage centrifugal pump with an in-line port arrangement, 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 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 installation.
For whom
- Industrial and manufacturing plants – the CVI 1-8 T INOX pump ensures stable pressure in high-pressure circulation systems, cleaning systems, and boiler-room supply installations.
- Single-family homes and small commercial buildings – the multistage design provides high head at a low but stable flow rate, sufficient for a single building or small installation.
- Maintenance departments – the in-line design makes it easier to replace the pump without dismantling the entire section of the installation, reducing downtime.
- Installers of fire-protection and air-conditioning systems – the pump is used in fire-protection and refrigeration systems, as well as in air-conditioning systems requiring continuous, reliable operation.
Applications
The IPRO CVI 1-8 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems, including waterworks, pressure-boosting stations, and pressure-boosting sets. In industrial environments, it is suitable for high-pressure circulation systems, air-conditioning and refrigeration systems, fire-protection systems, and the transfer of oil, glycol, and coolant. It is also used for boiler-room supply and in machine lubrication systems.
In agriculture, the pump serves irrigation systems, sprinkler systems, and irrigation installations, while in the services sector it is used in laundries and car washes. Selecting the right variant requires consideration of the NPSH characteristics of the suction system to avoid the risk of cavitation when operating near the maximum capacity point. The CVI 1-8 T INOX industrial pump operates in a three-phase system powered by 3~230 V or 3~400 V.
CVI 1-8 T INOX features – design and technical data
The CVI 1-8 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 not in 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 connection, 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 for operation in the range of 10–90°C.
The motors driving the CVI 1-8 T INOX belong to the IE3 efficiency class, 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 the cross-sections of power supply cables.

Frequently Asked Questions (FAQ)—CVI 1-8 T INOX vertical pump
What industrial applications is the CVI 1-8 T INOX pump suitable for?
The IPRO CVI 1-8 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 1-8 T INOX pump made of cast iron if it is an “INOX” pump?
The INOX designation applies to 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 of electric motors in accordance with the European Union’s 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 1-8 T INOX pump handle?
The pump is designed for chemically non-aggressive clean liquids with temperatures from -20°C to 90°C (up to 104°C by special order) and a pH range of 3–9.
What capacity does the CVI 1-8 T pump offer?
At the beginning of the designation of each model in the series is a number corresponding to the pump’s nominal capacity class—in the case of the CVI 1-8 T, this is 1 m³/h, or approximately 17 l/min. This relatively low flow rate makes the pump suitable for smaller installations: small service facilities, small cooling circuits, or dosing systems, rather than supplying entire multi-family buildings or large production lines with water.
Where can I buy the CVI 1-8 T INOX vertical pump?
