Domestic and foreign experience in pump engineering shows that the double-seat pumps are less sensitive to changes in the mode of operation and have higher reliability. For example, the pump company Little Giant 6 CIA Sump Pump recommends only double-seat design. In the USA and Canada in recent years working in the field of double-seat [...]

Principles calculation of heating
The circulating pump must compensate for the loss of pressure on all elements of the system. In gravity propulsion system is the potential energy of water stored in the upper distribution tank. Accordingly, the cumulative loss of the pipeline shall not exceed the static pressure of coolant in the system, expressed in meters of static [...]
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 [...]
Classic Pump Station
Classic pump station costly in construction and incapacitated by flooding Station on the submersible pumps Station on the submersible pumps – reducing construction costs and work in the flooded and dry conditions. Thus, also provided savings of 30-60% of investment costs by reducing the volume of construction (the receiver and the engine room combined) and [...]
