Description
CVI INOX 3-19 T – vertical multistage stainless steel centrifugal pump, in-line design
The IPRO CVI 3-19 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 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 in line with the pipeline, without the need to redesign the system.
Who it's for
- Industrial and manufacturing plants – the CVI 3-19 T INOX pump provides stable pressure in high-pressure circulation systems, cleaning systems, and boiler room supply systems.
- Small and medium-sized multifamily buildings – the multistage design provides high head at a flow rate sufficient for several to a dozen or so apartments or a small commercial building.
- Maintenance departments – the in-line design makes it easier to replace the pump without dismantling the entire section of the system, reducing downtime.
- Fire protection and air conditioning system installers – the pump is used in fire protection and refrigeration systems, as well as in air conditioning systems requiring continuous, reliable operation.
Applications
The IPRO CVI 3-19 T INOX pump is designed for pumping clean, chemically non-aggressive liquids in domestic water supply systems, including water supply networks, pressure booster systems, and pressure booster sets. W industrial environments, it is suitable for high-pressure circulation systems, air conditioning and refrigeration systems, fire protection systems, and for transferring oil, glycol, and coolant. It is also used to supply boiler rooms and in machine 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 near maximum capacity. The CVI 3-19 T INOX industrial pump operates on a three-phase system, powered at 3~230 V or 3~400 V.
CVI 3-19 T INOX features – design and technical data
The design of the CVI 3-19 T INOX pump 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 – 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 3-19 T INOX belong to efficiency class IE3, in accordance with the EU ecodesign regulation for electric motors. Efficiency and the power factor cos φ increase with motor power, affecting the selection of electrical protection and power supply cable cross-sections.

Frequently Asked Questions (FAQ) – CVI 3-19 T INOX vertical pump
What industrial applications is the CVI 3-19 T INOX pump suitable for?
The IPRO CVI 3-19 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 3-19 T INOX pump made of cast iron if it is an “INOX” pump?
The INOX designation refers 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 are structural components that do not come into contact with the liquid, so they are made of ASTM25B cast iron to provide adequate 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 defined by the EU Ecodesign Regulation. Higher efficiency means lower operating costs during continuous operation, which is particularly important in industrial installations operating in S1 mode.
What liquids can the CVI 3-19 T INOX pump?
The pump is designed for chemically non-aggressive clean 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 3-19 T pump?
The number at the beginning of each series model designation corresponds to the pump’s nominal capacity class. For the CVI 3-19 T, this is 3 m³/h, or approximately 50 l/min. This flow rate is suitable for small and medium-sized multi-family buildings, smaller commercial premises, and moderate industrial circulation systems, though it is not sufficient for large manufacturing plants or tall multi-occupant buildings.
