The Taco 0013 circulating pump is selected based on the need to move some heat from the boiler to heat appliances. This calculation takes the designers on the basis of the heat loss of external enclosures, thermal regime, supported the building, the number of consumers of thermal energy (floor space), etc. In the general case [...]

Why is the pump with the “wet” rotor in the drawings represent the dotted lines?
Typically, circulating pump should be chosen so that a given design point on the curve of maximum engine speed coincides with the point of highest efficiency or lay as close as possible to it. If a given operation is located between two characteristics of the pump, it is always necessary to choose the lower power [...]
How much energy is consumed by the pump for heating?
Developers pumping equipment pay much attention to reducing energy consumption. Therefore, modern circulation pumps energy efficiency class “A” uses less energy than conventional incandescent bulbs. Thus, the circulating pump Grundfos 15-42 F requires 9 to 35 watts depending on the mode of operation. In the year (for the home area of 200 m2), this would [...]
Electronic control units and protection Taco pumps
Electronic control units and protection of Taco have improved reliability, since they can be used in hydraulic systems, using water containing a small amount of sand. Besides the main purpose of electronic components – maintain a stable pressure in the system, Taco pump serves to protect the pump from working at the closed valve, “dry [...]
Pump characteristics and pump performance
Effect of motor speed As the frequency of rotation of the pump and the remaining constant terms of power consumption P varies in proportion to the value of the frequency n in the cube. P1/P2 = (n1/n2) 3 Based on these considerations, changing the frequency of rotation of the pump can be adapted to pump [...]
Histry of circulating pump
It was not until Swabian engineer Gottlob Baukneht not invented indoor or encapsulated pump, after which it became possible to use it in an accelerator circulation. His friend, Westphalian Wilhelm Oplender engineer, developed the design of such accelerators, and received her patent in 1929, pump impeller in the form of a propeller was installed in [...]
Types of Grundfos pumps
Grundfos pumps come with built-in ejector and without. The pumps have built-in ejector ensure the rise of water due to dilution. The disadvantage of such pumps may include high noise levels and therefore they must be installed outside a residential building in a special room. More appropriate to use such pumps to irrigate the garden. [...]
Pumps with wet rotor
Install the pump with gland-less directly or return line provides fast and intense movement of water. As a result, it is possible to use a plumbing pipeline with a smaller section. This leads to cost savings for the heating system. It also means that the lines of the system will now be significantly less water. [...]
