Description
CVI INOX 1-4 T – vertical multistage centrifugal pump made of stainless steel, in-line design
The IPRO CVI 1-4 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 system.
Who it's 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 commercial premises – 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 easy to replace the pump without dismantling an entire section of the system, reducing downtime.
- Fire protection and air conditioning system installers – the pump is used in fire protection and refrigeration systems, as well as air conditioning systems that require continuous, reliable operation.
Applications
The IPRO CVI 1-4 T INOX pump is designed for pumping clean liquids that are chemically non-aggressive in domestic water supply systems, including water supply networks, pressure boosting stations, and pressure boosting units. W industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, and for transferring oil, glycol, and coolant. It is also used for supplying boiler rooms and in machine lubrication systems.
W 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 system to avoid the risk of cavitation when operating near maximum capacity. The CVI 1-4 T INOX industrial pump operates in a three-phase system powered at 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 precise material selection according to the function of each component. The pump head and base, which are 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—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, and the O-rings 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 1-4 T INOX are in efficiency class IE3, compliant with the EU Ecodesign Regulation for electric motors. Efficiency and the power factor cos φ increase with motor power, affecting the selection of electrical protection devices and power supply cable cross-sections.

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, and domestic water supply systems.
Why are the pump head and base of the CVI 1-4 T INOX made of cast iron if it is an “INOX” pump?
The INOX designation refers 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 are load-bearing components and do not come into contact with the liquid, so they are made of ASTM25B cast iron, which provides adequate structural rigidity.
What is IE3 efficiency class, and why does it matter when selecting a pump?
IE3 is an energy efficiency class for electric motors, defined 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 liquids can the CVI 1-4 T INOX pump?
The pump is designed for clean, chemically non-aggressive liquids at temperatures from -20°C to 90°C (up to 104°C by special order) and with a pH range of 3–9.
What flow rate does the CVI 1-4 T pump offer?
The number at the beginning of each series model designation corresponds to the pump’s nominal flow class – for the CVI 1-4 T, this is 1 m³/h, or approx. 17 l/min. Yes, this low flow rate makes the pump suitable for smaller installations: small commercial premises, small cooling circuits, or dosing systems, rather than water supply for entire apartment buildings or large production lines.
