Pump-and-mixing unit Taco RMB-1 Radiant Mixing Block intended for installation on a comb floor heating, stainless steel, it regulates the temperature of the filing in the circuit radiator heating. Pump-and-mixing unit supports temperature coolant supply constant by mixing return water with the help of a three-way valve and a thermostat with overhead sensor.

* Setting range: 20 … 50 P
* Max. Working temperature: 90C (in the primary and secondary circuit)
* Max. pressure: 6 bar
* Max. differential pressure: 0,75 bar
* Kvs: 4,0
* Construction length: 315 mm

The circulation of coolant is carried out using a pump with electronic regulation. To protect the surface heating from the high temperature, oil-mixing unit is also equipped with an electric controller with overhead sensor.

The advantage of oil-mixing unit Taco RMB-1 Radiant Mixing Block is the ability to regulate the temperature of the filing of combined systems with radiators and panel heating.

Mounted and pressure-tested unit includes: Grundfos Alpha Pump with electronically controlled, three-way distribution valve, overhead valve with a sensor. Electric bill regulator is used to limit max. temperature source.

Use a circulating pump

What is the circulation pump

Circulator – a specially mounted pump, which instantly produces an internal air in difficult circumstances.

Use a circulating pump

Circulating pump – an important element of modern heating systems. Its application allows you to make better use of energy expended on heating the building. This is because, firstly, there is no need for a strong heating of the coolant required for circuits with natural circulation. Today, for example, are widely used system, where the temperature in the supply pipeline is maintained at 55oS. Secondly, there is an additional opportunity to adjust the flow of heat, depending on the need for it. In addition, the pump reduces the cost of the scheme as a whole, since it provides an opportunity to use pipe smaller than with the natural circulation diameter.

These circulators appeared some time ago, in the early 1950′s. In countries with decentralized heat they were very popular.

How does the circulator

The rotor of the circulating pump with the impeller immersed in the pumped medium. The fluid lubricates the bearings of the shaft and simultaneously cools the engine. Tightness of the engine parts, which is under stress, provides a dividing glass, made of stainless steel. The rotor shaft is often made of ceramics bearings – ceramic or graphite. The body pumps for heating systems in most cases, cast iron. For hot water, as a rule, apply the model with bronze or brass case.

Pumps of this type is practically noiseless and can operate for years without maintenance. Their installation, repair and replacement do not require labor-intensive operations, such as centering.

Technology development circulators

One of the ways to improve pumps like Taco Pump or Grundfos Pump was the union of its parts in blocks to facilitate their replacement. Such a unit can be easily disassembled into five modules: a pump casing, impeller, shaft bearings and the rotor, forming a single block in the cartouche, the motor housing with the stator, the terminal box.
