Description
CVI INOX 20-4 T – vertical stainless steel industrial centrifugal pump
The IPRO CVI 20-4 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed to precisely match the operating point in installations that require 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 along the pipeline, without the need to redesign the system.
Who it’s for
- Large commercial and public buildings – hotels, hospitals, and shopping centers benefit from a stable water supply at a flow rate of around 333 l/min.
- Industrial installers – the pump is suitable for complex pressure boosting systems serving large buildings.
- Manufacturing plants – cooling and process circuits in plants with high water demand benefit from the pump’s stable operation.
- Fire protection systems – high capacity and head support sprinkler systems in large buildings.
Applications
The IPRO CVI 20-4 T INOX pump is designed to pump clean liquids that are chemically non-aggressive in domestic water supply systems for large commercial and public buildings. W industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, and fire protection systems.
W industry, the pump is used to supply boiler rooms and in machine 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 20-4 T INOX industrial pump operates on a three-phase system.
CVI 20-4 T INOX features – design and technical specifications
The CVI 20-4 T INOX pump is designed with a precise allocation of materials 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, providing 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 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 20-4 T INOX cover a power range of 4 to 7.5 kW, depending on the selected head variant, and belong to efficiency class IE3, in accordance with the EU ecodesign regulation. The flange connection is DN50.

Frequently asked questions (FAQ) – CVI 20-4 T INOX vertical pump
What industrial applications is the CVI 20-4 T INOX pump suitable for?
The IPRO CVI 20-4 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 head and base of the CVI 20-4 T INOX pump made of cast iron if it is an “INOX” pump?
The INOX designation applies to 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 to provide adequate structural rigidity.
What is IE3 efficiency class, and why does it matter when choosing a pump?
IE3 is an energy efficiency class for electric motors defined by the EU Ecodesign Regulation. Higher efficiency means lower operating costs during continuous operation, which is particularly important in industrial installations running in S1 mode.
What liquids can the CVI 20-4 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 flow rate does the CVI 20-4 T offer?
At the beginning of each model designation in the series is a number corresponding to the pump’s nominal flow class. For the CVI 20-4 T, this is 20 m³/h, or approximately 333 l/min. This flow rate is suitable for large commercial and public facilities as well as manufacturing plants, although it is still below the scale required by the largest industrial plants and main water supply networks.
