CVI INOX 5-18 T – vertical stainless steel industrial centrifugal pump
The IPRO CVI 5-18 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed for precise operating point selection in systems 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 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.

-
Small and medium-sized multi-family buildings and office buildings – the CVI 5-18 T INOX pump provides stable pressure boosting at a flow rate sufficient for a dozen to several dozen apartments or a medium-sized office building.
-
Booster station installers – the compact in-line design makes it easy to install medium-capacity booster sets without modifying the pipeline.
-
Small and medium-sized industrial facilities – the pump is suitable for cooling circuits, industrial car washes, and supplying medium-sized boiler rooms.
-
Agriculture – suitable for irrigating larger crops and for greenhouses that require stable pressure.
Applications
The IPRO CVI 5-18 T INOX pump is designed to pump clean, chemically non-aggressive liquids in medium-scale domestic water supply systems, including residential booster stations and booster sets for office buildings and multi-family buildings. W industrial settings, it is suitable for cooling circuits, air conditioning systems, and supplying medium-capacity boiler rooms.
In agriculture, the pump handles irrigation for larger crops and greenhouse systems, while in the service sector, it serves industrial laundries and car washes with higher water demand. Selecting the right variant requires taking into account the NPSH characteristics of the suction system to avoid the risk of cavitation. The CVI 5-18 T INOX industrial pump operates on a three-phase system.
CVI 5-18 T INOX features – design and technical data
The CVI 5-18 T INOX pump is designed with materials precisely selected 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 to ensure 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-ring seals 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 5-18 T INOX cover a power range from 1.1 to 4 kW, depending on the selected head variant, and belong to efficiency class IE3, in accordance with the EU ecodesign regulation. The flanged connection is size DN25.

Frequently asked questions (FAQ) - CVI 5-18 T INOX vertical pump
What industrial applications is the CVI 5-18 T INOX pump suitable for?
The IPRO CVI 5-18 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 5-18 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 support the structure and do not come into contact with the liquid, so they are made of ASTM25B cast iron, which provides the required 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, 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 liquids can the CVI 5-18 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 on special order) and with a pH range of 3–9.
What is the capacity of the CVI 5-18 T pump?
The number at the beginning of each series model designation corresponds to the pump's nominal capacity class - for the CVI 5-18 T, this is 5 m³/h, or approximately 83 l/min. This flow rate is suitable for medium-sized apartment buildings, office buildings, and small to medium-sized industrial facilities, though it is still not suitable for large commercial buildings or heavy industry.
Where can I buy the vertical CVI 5-18 T INOX pump?
Dambat does not sell directly. The CVI 5-18 T INOX pump is available from our trade partners, plumbing wholesalers, and authorized online distributors.
Is the IPRO CVI 5-18 T INOX pump covered by a manufacturer's warranty?
