Description
CVI INOX 32-3-2 – vertical industrial stainless steel centrifugal pump
The IPRO CVI 32-3-2 INOX is a vertical, multistage centrifugal pump with in-line ports, designed for precise duty-point selection in installations 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 complies 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.
Who it is for
- Large manufacturing plants – the food, chemical, and manufacturing industries use the CVI 32-3-2 INOX pump in process installations with a flow rate of approximately 533 l/min.
- Water supply networks and municipal pressure-boosting stations – the pump serves as a base unit in larger booster stations supplying housing estates or districts.
- Large fire protection systems – high capacity and head support sprinkler systems in large industrial facilities.
- Refrigeration and air-conditioning systems in large facilities – the pump ensures stable circulation in extensive cooling systems.
Applications
The IPRO CVI 32-3-2 INOX pump is designed for pumping clean, chemically non-aggressive liquids in large domestic water supply systems and industrial installations with increased flow requirements. It performs well in high-pressure circulation systems, air-conditioning and refrigeration systems, and fire protection systems in large facilities.
In industry, the pump is used to supply boiler rooms and in processes requiring a large, stable water flow. Selecting the right variant requires considering the NPSH characteristics of the suction system to avoid the risk of cavitation when operating at full capacity. The CVI 32-3-2 INOX industrial pump operates in a three-phase system.
CVI 32-3-2 INOX features – design and technical data
The CVI 32-3-2 INOX pump is constructed with materials precisely selected according to the function of each component. The pump head and base, as load-bearing components not in 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, while the O-rings are made of EPDM/FKM. The mechanical cartridge seal (silicon carbide / tungsten carbide / EPDM) is designed for operation in the 10–90°C range.
The motors driving the CVI 32-3-2 INOX cover a power range from 3 to 15 kW, depending on the selected head variant, and belong to the IE3 efficiency class, compliant with the EU ecodesign regulation. The flanged connection is DN65.

Frequently asked questions (FAQ) – CVI 32-3-2 INOX vertical pump
What industrial applications is the CVI 32-3-2 INOX pump suitable for?
The IPRO CVI 32-3-2 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 32-3-2 INOX pump made of cast iron if it is an “INOX” pump?
The INOX designation applies to components 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, ensuring adequate structural rigidity.
What is the IE3 efficiency class, and why is it important when selecting a pump?
IE3 is the energy-efficiency class of 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 liquid can the CVI 32-3-2 INOX pump?
The pump is designed for clean, chemically non-aggressive liquids with temperatures from -20°C to 90°C (up to 104°C on special order) and a pH range of 3–9.
What capacity does the CVI 32-3-2 pump offer?
At the beginning of the designation of each model in the series is a number corresponding to the pump’s nominal capacity class—in the case of the CVI 32-3-2, this is 32 m³/h, or approximately 533 l/min. This flow rate corresponds to the scale of large manufacturing plants and municipal pressure-boosting stations, exceeding the capabilities of pumps intended for individual buildings.
