Why is the climate system at the trade center in Paraguay equipped with a in-line pump series L by Saer Elettropompe? The reason is its continuous and reliable operation, which the model provides in HVAC applications. “The linear, also known as in-line pumps, of the L series are a safe, highly efficient and flexible solution for various domestic and industrial installations, and are primarily preferred in heating, cooling and domestic hot water systems,” Eng. Alexander Georgiev, Saer’s regional sales representative for Bulgaria, North Macedonia, Albania, Kosovo, Greece and Cyprus, told BalkanEngineer.com.

For installation and maintenance teams, the right choice of pump means reduced risk, better operational stability and satisfied users. For this reason, the Paraguay center relies on the L 20 HP series for HVAC systems, but the model is suitable for other applications, "The L series works with fluids with temperatures up to 140 °C, and is made of cast iron, ductile iron or stainless steel. The monoblock version is for sizes up to DN 65, and larger sizes are available with a rigid connection and standardized motors. A total of 170 models are available," explained Eng. Georgiev.
“Saer L in-line pumps are available in different configurations based on fluid characteristics and conditions of use, with a vertical installation version also available,” Besides that, their foundation allows for its height to be regulated, to reduce the amount of pressure on the pipes. Additionally, it is possible to undergo processes with special paints and surfaces, as well as a PAT version.
Pumps can be delivered with the following optional accessories:
- Fittings;
- Basic kit;
- Special coatings;
- Motor-mounted Saer IVM-IVT speed inverter – up to 18.5 kW;
- Electrical distribution board – according to site needs.
"In fact, the L range is also integrated in Bulgaria, where a total of 34 different models ensure the operation of the heating system in a vegetable greenhouse," added Eng. Georgiev.
