Even in the recent past, in the heating system for the circulation of the coolant in residential buildings or small production facilities with an area of 100 — 200 m2, industrial pumps of the brand or km with a capacity of 1.1 or 1.5 kW. Today, instead of these pumps, energy-efficient pumps Wilo-Star, Wilo-Top, etc. were replaced., power, like an ordinary electric incandescent lamp from 70 to 150 watts. What minimal knowledge and information must be owned in order to choose the right pumping equipment or control his choice. The main indicators for choosing pumping equipment are performance and maximum pressure. If the pitch pump is designed for a heating system or hydraulic pump (hot water supply), then it is necessary to take into account the temperature of the water. The performance of pumping equipment is the volume of water that it pumps over a certain time. In the passport, this characteristic is Q, M3/h. If the pump is circulating, for the heating or water supply system, then it is necessary to take into account the volume of water that is in the system. In the event that the pump is selected for an artesian well (submersible pump), then its performance must correspond to the debit of the well and your need for water.
