CIRCULATING PUMP WATER PUMPS

WATER PUMPS PUMPING TECHNOLOGY Until recently, central heating installations in private house building used mainly gravity water circulation. In such a cycle, the water circulates in the installation thanks to the density difference caused by temperature difference between the supply (the outlet of heated water from the boiler) and the return (the inlet of cool water from the radiators back into the boiler). The faults of such a system include significant inertia, non-uniform distribution of heat and big diameter pipelines. Presence of a pump in a central heating installation allows to...

PUMPING TECHNOLOGY WATER PUMPS Selection of electronically controlled pumps Functioning of electronically controlled pumps has been adjusted to annual heating energy consumption standards. The average annual consumption is showed in figure 2, illustrating seasonal overload. The proper selection of regulated pumps is shown in figures 3, 4 and 5. (Comparison of pump's characteristics determined by the design with actual technical characteristics of a particular pump). Regulation 'of eortslant pressure P Regulation fw proportional pressure p The pump is over motored While using regulated pumps...

WATER PUMPS PUMPING TECHNOLOGY Practical advice Electrical connection Connect the electric cables and earthing with a slight sag to the terminal strip, and plug in according to the marking. External electric protection is not required. The pump motor can be placed freely at 90° to the pump body, nevertheless it is important that the cable lead is not turned upwards and the terminal box is not located below the motor (see figures 2, A1, A2, A3, A4). The terminal box connection and the contacts between the box and the motor winding must be protected against humidity. It is forbidden to mount...

WATER PUMPS CIRCULATING FOR HEATING AND CONDITIONING ELECTRONIC Energy-saving Speroni SCRE 40 - SCRE 60 electronic circulation pumps for central heating Along with the series Delta plus we have achieved a circulation pump which is classified in energy efficiency class "A". Using a Speroni pump instead of a conventional circulation pump helps to reduce energy consumption up to80%, while keeping the hydraulic power at a comparable level. The "One touch" option allows you to choose from six different performance curves.

SCRE PLUS- The display is lit when pump is plugged in. The LED display shows the current power Faults are shown on the display as "E1", "E2" or "E3" errors. When the night setback function is activated and the pump is switching to this mode, then the "-C" symbol appears Curve selection button By pressing the button pump settings change. Pressing the button seven times causes to select one by one all the options and then return to the first one.

WATER PUMPS ELECTRONIC CIRCULATING PUMPS FOR CENTRAL HEATING SCRE PLUS Pump settings Regulation of proportional pressure When operating the pump adjusts to the settings of proportional pressure. Whereas differential pressure is controlled by the pump, depending on the current of the flow. Lines (characteristics) of proportional pressure are denoted with PD1 to PD4 symbols on corresponding Constant rotation speed control Lines (characteristics) of constant speed rotation are denoted with I to III symbols on the Q/H graph. This type of control allows the pump to maintain constant rotation...
