Description
CVI INOX 20-4 T – vertical industrial centrifugal pump made of stainless steel
CVI 20-4 T INOX brand IPRO is a vertical, multi-stage centrifugal pump in an in-line system, designed for precise selection of the operating point in installations requiring repeatable performance and low noise level. The impeller, diffuser and all hydraulic elements in contact with the medium are made of AISI 304 stainless steel, and the three-phase motor of the IE3 efficiency class ensures compliance with the current energy efficiency requirements for industrial drives. The in-line design allows for installation directly in the pipeline axis, without the need to redesign the installation.
For whom
- Large commercial and public facilities – hotels, hospitals and shopping centers benefit from stable water supply with a flow of 333 l/min.
- Industrial installers – the pump works well in extensive hydrophore sets serving large buildings.
- Production plants – cooling and process circuits in plants with increased water demand benefit from stable pump operation.
- Fire protection systems – high efficiency and lifting support sprinkler installations of large facilities.
Application
CVI 20-4 T INOX pump IPRO is intended for pumping clean, chemically non-aggressive liquids in utility water supply systems of large commercial and public facilities. In an industrial environment, it is used in high-pressure circulation systems, air conditioning and refrigeration systems, and fire protection systems.
In industry, the pump is used to power boiler rooms and in machine cooling systems, and in agriculture - to irrigate large areas. Selecting the appropriate variant requires taking into account the NPSH characteristics of the suction installation to avoid the risk of cavitation. The CVI 20-4 T INOX industrial pump operates in a three-phase system.
Features of CVI 20-4 T INOX – design and technical data
The design of the CVI 20-4 T INOX pump is based on the precise separation of materials according to the functions of individual elements. The pump head and base, as load-bearing elements that do not have 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 elements in contact with the medium - inlet, outlet, impeller, diffuser, pump body, 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 package mechanical stuffing box (silicon carbide / tungsten carbide / EPDM) is designed to operate in the range of 10–90°C.
The motors driving the CVI 20-4 T INOX cover a power range from 4 to 7.5 kW, depending on the selected lifting variant, and belong to the IE3 efficiency class, in accordance with the EU Ecodesign Regulation. Connection flanged ones are made in size DN50.

Frequently asked questions (FAQ) – CVI 20-4 T INOX vertical pump
What industrial applications is the CVI 20-4 T INOX pump suitable for?
CVI 20-4 T INOX pump IPRO is used in high-pressure circulation systems, air-conditioning and refrigeration systems, fire protection systems, boiler room power supply and in utility water supply systems.
Why are the head and base of the CVI 20-4 T INOX pump made of cast iron if it is an "INOX" pump?
The INOX marking applies to elements in direct contact with the pumped medium - impeller, diffuser, body, inlet and outlet - made of AISI 304 stainless steel. The pump head and base have a load-bearing function, they do not come into contact with the liquid, therefore they are made of ASTM25B cast iron, ensuring adequate structural stiffness.
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 in continuous operation, which is particularly important in industrial installations operating in S1 mode.
What liquid can CVI 20-4 T 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 pH in the range of 3–9.
What performance does the CVI 20-4 T pump offer?
At the beginning of the designation of each series model there is a number corresponding to the nominal efficiency class of the pump - in the case of CVI 20-4 T it is 20 m³/h, i.e. approx. 333 l/min. This flow allows it to service large commercial and public facilities and production plants, although it still does not match the scale of the largest industrial plants or main water supply networks.
