Description
CVI INOX 20-10 T – vertical industrial stainless-steel centrifugal pump
The IPRO CVI 20-10 T INOX is a vertical multistage centrifugal pump with in-line connections, designed for precise duty-point selection in systems 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 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 system.
Who is it for?
- Large commercial and public buildings – hotels, hospitals, and shopping centers benefit from a stable water supply at a flow rate of approximately 333 l/min.
- Industrial installers – the pump is suitable for extensive booster sets serving large buildings.
- Manufacturing plants – cooling and process circuits in plants with increased 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 20-10 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems for large commercial and public buildings. In industrial environments, it is suitable for 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 cooling systems, while in agriculture it is used to irrigate large areas. Selecting the right variant requires taking into account the NPSH characteristics of the suction system to avoid the risk of cavitation. The CVI 20-10 T INOX industrial pump operates in a three-phase system.
CVI 20-10 T INOX Features – Design and Technical Data
The design of the CVI 20-10 T INOX pump is based on the precise allocation of materials 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 to operate within a temperature range of 10–90°C.
The motors driving the CVI 20-10 T INOX cover a power range from 4 to 7.5 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 20-10 T INOX vertical pump
What industrial applications is the CVI 20-10 T INOX pump suitable for?
The IPRO CVI 20-10 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 20-10 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 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 20-10 T INOX pump handle?
The pump is designed for clean, chemically non-aggressive 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 20-10 T pump offer?
At the beginning of the designation of each series model is a number corresponding to the pump's nominal capacity class—in the case of the CVI 20-10 T, this is 20 m³/h, or approximately 333 l/min. This flow rate is sufficient to serve large commercial and public utility facilities as well as manufacturing plants, although it still does not match the scale of the largest industrial plants or main water supply networks.
