Page 8: Product Description
Product Description Figure 2 and Figure 3 show a typical single-pump and multi-pump system using the unit. When the system is connected directly to the water supply use a low-pressure switch on the suction side. Figure 2: Single-pump system Figure 3: Multi-pump system Pump with e-SM Motor Drive Diaphragm pressure tank Distribution panel... - Page 9 Pressure tank A diaphragm pressure tank is used on the discharge side of the pump to maintain pressure in the pipes when there is no water demand. The unit stops the pump from continuing to run at zero demand and reduce the size of the tank that is required for supply purposes.
