Description
CVI INOX 1-4 T – vertical multistage centrifugal pump made of stainless steel, in-line configuration
The IPRO CVI 1-4 T INOX is a vertical multistage centrifugal pump with an in-line port configuration, designed for precise selection of the operating point in installations requiring repeatable 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 ensures compliance 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.
Who it is for
- Industrial and manufacturing plants – the CVI 1-4 T INOX pump provides stable pressure in high-pressure circulation systems, cleaning systems, and boiler-room supply installations.
- Single-family homes and small service facilities – the multistage design provides high head at a low but stable flow rate, sufficient for a single building or a small installation.
- Maintenance departments – the in-line configuration makes it easier to replace the pump without dismantling the entire section of the installation, reducing downtime.
- Fire protection and air-conditioning system installers – the pump is used in fire protection, refrigeration, and air-conditioning systems requiring continuous, reliable operation.
Applications
The IPRO CVI 1-4 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. 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 supplying boiler rooms and in machine lubrication systems.
In agriculture, the pump serves irrigation systems, sprinkler systems, and irrigation installations, while in the service sector it is used in laundries and car washes. Selecting the right variant requires considering the NPSH characteristics of the suction installation to avoid the risk of cavitation when operating at a point close to maximum capacity. The CVI 1-4 T INOX industrial pump operates in a three-phase system powered by 3~230 V or 3~400 V.
CVI 1-4 T INOX features – design and technical data
The CVI 1-4 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 in contact with the medium – inlet, outlet, impeller, diffuser, pump casing, discharge nozzle, and cover – are made of AISI 304 stainless steel. The neck ring is made of PTFE, while the O-rings are made of EPDM/FKM. The mechanical cartridge seal (silicon carbide / tungsten carbide / EPDM) is designed for operation in the 10–90°C range.
The motors driving the CVI 1-4 T INOX belong to efficiency class IE3, compliant with the EU regulation on ecodesign requirements 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 1-4 T INOX vertical pump
What industrial applications is the CVI 1-4 T INOX pump suitable for?
The IPRO CVI 1-4 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 1-4 T INOX pump made of cast iron if it is an "INOX" pump?
The INOX designation applies to the components 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, 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 under 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 1-4 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 on special order) and a pH range of 3–9.
What flow rate does the CVI 1-4 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 1-4 T, this is 1 m³/h, or approximately 17 l/min. This low flow rate makes the pump suitable for smaller installations: small service facilities, small cooling circuits, or dosing systems, rather than supplying entire multifamily buildings or large production lines with water.
Where can I buy the CVI 1-4 T INOX vertical pump?
