Description
CVI INOX 1-8 T – vertical multistage stainless steel centrifugal pump, in-line design
The IPRO CVI 1-8 T INOX is a vertical, multistage centrifugal pump with in-line ports, designed for precise operating point selection in installations requiring repeatable 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 installation.
Who it's for
- Industrial and manufacturing plants – the CVI 1-8 T INOX pump provides stable pressure in high-pressure circulation systems, cleaning systems, and boiler room supply installations.
- Single-family homes and small commercial premises – the multistage design provides high head at a low but stable flow rate, sufficient for a single building or a small installation.
- Maintenance departments – the in-line design makes it easier to replace the pump without dismantling the entire section of the installation, reducing downtime.
- Fire protection and air conditioning system installers – the pump is used in fire protection, refrigeration, and air conditioning systems requiring continuous, reliable operation.
Applications
The IPRO CVI 1-8 T INOX pump is designed for pumping clean liquids that are chemically non-aggressive in domestic water supply systems, including water mains, pressure boosting stations, and pressure boosting sets. W industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, and transferring oil, glycol, and coolant. It is also used for boiler room supply and machinery lubrication systems.
W agriculture, the pump serves irrigation systems, sprinkler systems, and irrigation installations, while in the services sector it is used in laundries and car washes. Selecting the right variant requires taking the NPSH characteristics of the suction system into account to avoid the risk of cavitation when operating close to maximum capacity. The CVI 1-8 T INOX industrial pump operates in a three-phase system powered by 3~230 V or 3~400 V.
CVI 1-8 T INOX features – design and technical data
The CVI 1-8 T INOX pump design is based on 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, 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 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 to operate within the 10–90°C range.
The motors driving the CVI 1-8 T INOX belong to efficiency class IE3, in compliance with the EU Ecodesign Regulation for electric motors. Efficiency and the cos φ power factor increase with motor power, which affects the selection of electrical protection devices and power supply cable cross-sections.

Frequently asked questions (FAQ) – CVI 1-8 T INOX vertical pump
What industrial applications is the CVI 1-8 T INOX pump suitable for?
The IPRO CVI 1-8 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 1-8 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 provide structural support and do not come into contact with the liquid, so they are made of ASTM25B cast iron to ensure adequate structural rigidity.
What is the 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 translates into lower operating costs during continuous operation, which is particularly important in industrial installations operating in S1 mode.
What liquids can the CVI 1-8 T INOX pump?
The pump is designed for chemically non-aggressive clean liquids with a temperature ranging from -20°C to 90°C (up to 104°C by special order) and a pH range of 3–9.
What capacity does the CVI 1-8 T pump offer?
The number at the beginning of each model designation in the series corresponds to the pump’s nominal capacity class – for the CVI 1-8 T, this is 1 m³/h, or approx. 17 l/min. Yes, this low flow rate makes the pump suitable for smaller installations: small commercial premises, small cooling circuits, or dosing systems, rather than supplying water to entire apartment buildings or large production lines.
