Recently, as a component of heating systems, Wilo products are increasingly appearing. The circulating pump of this company is capable of increasing the efficiency of heating, increasing the coolant capacity in a closed cycle. Due to the fact that such devices must be located in the mode of permanent operation, strict requirements are imposed on the choice of this or that model. They can be met by choosing a Wilo pump, its technical characteristics are successfully supplemented with operational advantages.

This equipment originates in the company, founded in 1872. It was then that the founder of the company opened the manufactory. She produced consumer goods made of steel and copper. The first circulation pump was released in 1929. Then he worked on the development of the son of the founder, he also engaged in the re-profiling of production for the manufacture of household mechanisms. Today the company's products have an impeccable reputation. It was achieved by many years of work and the desire to create innovative novelties.

Wilo (circulation pump): specifications and applications

Wilo is a circulation pump, which is popular due to the ability to use this equipment in many areas. Devices can become part of:

  • industrial circulation plants;
  • systems of water heating;
  • air-conditioning systems;
  • cold water supply systems.

The described units have a successful operating experience, they have been checked by time, therefore they found their wide distribution in the conditions of modern thermal points. The most popular of the range of nomenclature can be considered pumps WILO Star and WILO TOP.

Areas of use and main features of "Vailo Star"

Wilo is a circulation pump that is supplied for sale in a variety of WILO Star. This equipment has a wet rotor and a threaded connection, which is used in systems of water heating and warm floors. This equipment is also used in industrial circulation systems, in air conditioning systems, as well as cold water supply systems.

Technical characteristics of "Vailo Star"

Wilo is a circulation pump, which you can find on sale under the Star RS marking. In this case we are talking about equipment with protection class IP.44. The maximum working pressure is 10 bar. Before purchasing the equipment it is important to take into account that the suction head in the suction pipe must be kept to a minimum.

Areas of use and features of the WILO TOP pump

The Wilo Top circulation pump is used for pumping water in domestic hot water and heating systems, as well as in closed industrial systems and systems that are designed for pumping drinking water. In the latter case, we are talking about the TOP-Z model. When choosing a feature of the pumped medium, it is necessary to take into account that, in particular, the case when the pump, or more precisely, its internal parts should be in contact with drinking water.

Depending on the diameter, the equipment has a flanged or threaded connection. The devices can be used for pumping:

  • water for food production;
  • ordinary drinking water;
  • technical water for the heating system;
  • water-glycol mixture and water, in which case a one-to-one ratio is used.

This Wilo circulation pump features a built-in motor protection and a resistance to blocking currents. All this prolongs the period of operation. There is also a heat-insulating casing in the device. The unit has three speeds and does not require maintenance.

Technical specifications WILO Star RS

Use the above equipment can be at ambient temperature in the range from 0 to +40 ° C. The pump surface temperature during operation should not be above +160 ° C. The device corresponds to the degree of protection IP 44. To determine the maximum operating pressure, it is necessary to familiarize yourself with the table that is attached with the structure.

Wilo-Star-RS 25/4 pump specifications

Circulation pump Wilo 25 has a motor located horizontally. The terminal box can have a position for 3, 6, 9 and 12 hours. At purchase the terminal box is in a factory position. The advantage of the equipment is an engine that is resistant to blocking currents.

The unit operates due to a two-pole single-phase motor with an integrated capacitor. A pump is designed for industrial circulation systems, heating, air conditioning and cold water supply systems. The Wilo Star circulation pump can be used for installation with a horizontal shaft arrangement. The wiring is simplified, this is guaranteed by the removable cable entry of the terminal box. The control is carried out manually, the speed of the stages can correspond to one of three positions.

At the heart of the pump housing is gray cast iron, the shaft is made of stainless steel, while the impeller is made of synthetic material. Bearings are made of metallografite. The circulating pump Wilo Star RS is supplied with operating and installation instructions, seals and pump equipment.

Technical features

Circulating pumps for heating Wilo can significantly increase the heat transfer of water and the efficiency of the heating system. The connection allows the use of trunks with a smaller cross-section. The results are:

  • reduction of fuel consumption;
  • savings without loss of quality of work;
  • reduction of harmful gas emissions.

The design of the equipment was created for continuous operation. This indicates that each element is highly reliable. Manufacturers have taken care of saving electricity consumption. The unit will consume 250 watts per day. When working, the devices do not produce noise, because there is no fan inside.

Circulating pumps for heating Wilo are available for sale in two versions - with a dry and wet rotor. The latter are used for the arrangement of heating systems inside premises with a small area. The motors in them during operation are cooled by water, which is pumped by the equipment. This allows you to get an additional plus, expressed in the absence of noise.

The models differ not only in power, but also in the volume of pumped water. The weakest are able to increase the efficiency of the system by 200 m 2. If we are talking about powerful devices, they are designed to heat areas of 1000 m 2. Both have compact dimensions and a simplified design. However, the height of the head is the main technical characteristic. The manufacturer claims that only such circulating pumps are capable of creating the 8th height, while the maximum possible flow rate is 5 m / h.

Mounting Features

Before installing the unit, remove the thermal insulation. Installation is carried out after the completion of the work on flushing the system, soldering it and welding the pipelines, this is because the dirt can disrupt the operation of the equipment. The pump should be located in an accessible location, which will facilitate subsequent monitoring and replacement. It is important to install a shut-off valve in front of the equipment or behind it. This will prevent water from draining from the system and refilling when replacing equipment.


Circulation pumps Wilo RS have working mechanisms made of materials resistant to corrosion. Automation can control the operation of the system. The equipment has a built-in thermostat, whereas all functions can be seen on the LCD. But the user has the possibility of manual switching, which allows you to monitor the rotation of the working shaft.
