Product detailed description
S4 12/18 T 4GG 4" submersible pump for boreholes and wells - 3.0kW - 3x400V
Submersible centrifugal pumps for wells and boreholes with a diameter greater than 4“. The pumps are used for pumping out water, for pressurising and supplying water to the distribution systems of small and large buildings, both residential and industrial, as well as for irrigation, washing and fire-fighting systems. Technopolymer impellers with suction rings made of stainless steel. Pump casing, shaft, motor coupling, integrated suction filter and cable guard made of stainless steel. Suction body, delivery body and lifting eyes are made of stainless steel AISI 304. Removable integrated check valve made of technopolymer or with a stainless steel plate (depending on the model). Technopolymer impellers designed to ensure a high level of efficiency in compliance with directive 2009/125/EC (Eco design - ErP) with an MEI index ≥ 0.4 over the whole range. Certified by ACS, WRAS certificate. The 4GG motor is a two-pole asynchronous motor; the parts in contact with water are made of stainless steel AISI 304. The pressure block and bushings are cooled and lubricated by a mixture of water and glycol. The rotor runs in sliding radial bearings, axial load is taken up by a robust sliding thrust bearing.

Frequently Asked Questions
- How do I choose the right pump output/head? It must cover the pressure losses of your specific circuit (pipe length, number of fittings) - if in doubt, consult a heating engineer, who will size the pump precisely for you.
- Must installation be carried out by a professional? Fitting the pump into prepared pipework can be handled by a DIYer; we recommend having the electrical connection and system balancing checked by a professional.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
