CVI INOX 5-8 T – vertical industrial stainless steel centrifugal pump
The IPRO CVI 5-8 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed for precise selection of the operating point 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 meets 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 5-8 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 plants – 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 requiring stable pressure.
Applications
The IPRO CVI 5-8 T INOX pump is designed for pumping clean liquids that are chemically non-aggressive in medium-scale domestic water supply systems, such as residential booster stations and booster sets for office buildings and multi-family buildings. W industrial environments, it is suitable for cooling circuits, air-conditioning systems, and supplying medium-capacity boiler rooms.
W In agriculture, the pump serves larger crop irrigation systems and greenhouse installations, while in the service sector it is used in industrial laundries and car washes with increased water demand. Selecting the right variant requires taking the NPSH characteristics of the suction system into account to avoid the risk of cavitation. The CVI 5-8 T INOX industrial pump operates on a three-phase supply.
CVI 5-8 T INOX features – design and technical data
The CVI 5-8 T INOX pump is designed with materials precisely selected for 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 that come into contact with the medium – inlet, outlet, impeller, diffuser, pump casing, discharge port and cover – are made of AISI 304 stainless steel. The throat 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 5-8 T INOX cover a power range from 1.1 to 4 kW, depending on the selected head variant, and are in efficiency class IE3, in accordance with the EU Ecodesign Regulation. The flanged connection is size DN25.

Frequently asked questions (FAQ) – CVI 5-8 T INOX vertical pump
What industrial applications is the CVI 5-8 T INOX pump suitable for?
The IPRO CVI 5-8 T INOX pump is used in high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, boiler room water supplies, and domestic water supply systems.
Why are the head and base of the CVI 5-8 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, which provides adequate structural rigidity.
What is the IE3 efficiency class, and why is it important when selecting a pump?
IE3 is an energy efficiency class for electric motors, as defined by the EU Ecodesign Regulation. Higher efficiency translates into lower operating costs during continuous operation, which is especially important in industrial installations operating in S1 mode.
What liquids can the CVI 5-8 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 5-8 T pump?
The first number in the designation of each model in the series indicates the pump’s nominal capacity class – for the CVI 5-8 T, this is 5 m³/h, or approx. 83 l/min. This flow rate is suitable for medium-sized apartment buildings, office buildings, and small- to medium-sized industrial plants, but is still not sufficient for large commercial facilities or heavy industry.
Where can I buy the CVI 5-8 T INOX vertical pump?
Dambat does not sell directly to customers. The CVI 5-8 T INOX pump is available from our trading partners, plumbing wholesalers, and authorized online distributors.
Is the IPRO CVI 5-8 T INOX pump covered by a manufacturer’s warranty?
IPRO – 36 months (3 years) of manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
