CVI INOX 5-7 T – vertical industrial stainless steel centrifugal pump
The IPRO CVI 5-7 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed to precisely match the operating point in installations requiring consistent flow 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-class three-phase motor ensures compliance with 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
-
Small and medium-sized apartment buildings and office buildings – the CVI 5-7 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.
-
Pressure-boosting station installers – the compact in-line design makes it easy to install medium-capacity pressure-boosting units 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 5-7 T INOX pump is designed for pumping clean liquids that are not chemically aggressive in medium-scale domestic water supply systems, such as residential pressure-boosting stations and pressure-boosting units for office buildings and apartment blocks. W In industrial settings, it is suitable for cooling circuits, air conditioning systems, and supplying medium-capacity boiler rooms.
W In agriculture, the pump handles irrigation for larger crops and greenhouse systems, while in service businesses, 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 5-7 T INOX industrial pump runs on a three-phase power supply.
CVI 5-7 T INOX features - construction and technical data
The CVI 5-7 T INOX pump is designed with materials precisely selected according to the function of each component. The pump head and base, as load-bearing components with no 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 housing, 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 at 10–90°C.
The motors driving the CVI 5-7 T INOX cover a power range of 1.1 to 4 kW, depending on the selected lift variant, and belong to efficiency class IE3, in accordance with the EU Ecodesign Regulation. The flanged connection is DN25.

Frequently asked questions (FAQ) - CVI 5-7 T INOX vertical pump
What industrial applications is the CVI 5-7 T INOX pump suitable for?
The IPRO CVI 5-7 T INOX pump is used in high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, boiler room supply systems, and domestic water supply systems.
Why are the head and base of the CVI 5-7 T INOX pump made of cast iron if it's an "INOX" pump?
The INOX designation applies to parts 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, which provides adequate structural rigidity.
What is the IE3 efficiency class, and why is it important when choosing a pump?
IE3 is an energy efficiency class for electric motors, as defined by the EU Ecodesign Regulation. Higher efficiency means lower operating costs during continuous operation, which is especially important in industrial installations operating in S1 mode.
What liquids can the CVI 5-7 T INOX pump?
The pump is designed for clean, chemically non-aggressive liquids with a temperature range of -20°C to 90°C (up to 104°C on special order) and a pH range of 3–9.
What capacity does the CVI 5-7 T pump offer?
The first number in each model designation in the series corresponds to the pump's nominal capacity class - for the CVI 5-7 T, this is 5 m³/h, or approximately 83 l/min. This flow rate can serve medium-sized apartment buildings, office buildings, and small to medium-sized industrial plants, although it is still not suitable for large commercial facilities or heavy industry.
Where can I buy the vertical CVI 5-7 T INOX pump?
Dambat does not sell directly to customers. The CVI 5-7 T INOX pump is available from our sales partners, plumbing wholesalers, and authorized online distributors.
Is the IPRO CVI 5-7 T INOX pump covered by a manufacturer's warranty?
