Radiant heat circulating pumps are completely underground, and usually do not have the above ground part (the superstructure). They are small and management of automated. Underground, for example, can be designed station groundwater abstraction. The shape of the underground part of a plan circulating pumps are: rectangular, circular, elliptical and irregular shape.
The rectangular shape provides better conditions for the construction of both underground and above ground part of standardized parts. Round and elliptical shapes make it easier to perceive the hydrostatic pressure and the pressure of the soil with concrete and reinforced concrete structures of the underground part, and also to build an down-comer means.
In their management circulating pumps can be:
with manual control – all or part of the operations management unit is made attendants;
automatic – all operations to enable and shut down units are made automatically depending on water levels in reservoirs, pressure or water flow in plumbing pipe;
semiautomatic – pump unit is switched on or off from a single command given operational personnel, and all further work is done automatically;
Remote control – control of the pumping station is made from the control tower, far from the station.
Getting the design, you must select the appropriate type of Taco 007 pump.
This solution can be adjusted in the design process. In practice, one or another type of Taco 007 pump is usually chosen by the techno-economic comparison of several options.
