S4 8/21 T 4OL submersible 4" borehole and well pump - 3,0kW - x230V
Submersible centrifugal pumps for studne and vrty, with priemerom larger as 4". Pumps are used for pumping-out water, for tlakovanie and supply water, to rozvodov small i large objektov, residential i industrial, further for irrigation, washing and fire-fighting systems. Technopolymer impellers, with suction rings, from stainless steel. Casing pump, shaft, spojka with motorom, integrated suction filter and cover cable from stainless steel. Sacie teleso, discharge teleso and hanging eyes are from stainless ocele AISI 304 from mikroliatiny. Removable integrated return valve from technopolymer or from stainless steel (in dependence from modelu). Technopolymer impellers designed to zaisteniu vysokej level efficiency in accordance witho smernicou 2009/125/ES (Eco design - ErP) with indexom MEI ≥ 0,4 for whole range. Have certificate ACS, certificate WRAS.
Motor 4OL is two-pole asynchronous motor, whose parts, which are in styku with water, are made of stainless steel AISI 304L. Cooling and mazanie ball bearings, ensures special food-grade liquid. Rewindable stator is mounted in puzdre from stainless steel AISI 304L, pripevnenom steel pins to hornej podpere motor.

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 can size the pump precisely for you.
- Must installation be carried out by a professional? Fitting the pump into a prepared pipe run can be handled by a handy homeowner; 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.
