Diesel Engine Fire Pump Controller
The common controller for fire pump is fabricated from mild steel with red epoxy powder coating and have all the required controls complying with the applicable standards (NFPA). It is used together with diesel engine fire fighting pumps. The product has a variety of protection functions such as overload protection, short circuit protection, lack of phase protection, pump water leakage protection, motor overtemperature and leakage protection. It has both single pump and multi-pump control mode and manual and auto starting mode.
Manual starting: If setting up the black 2# three-way switch to the”Manual”position on the control panel mode, you can use "Manual" start button and "Manual" stop button to control the starting or stopping of the diesel engine pump. When setting the black three-way switch to the "stop" position, the diesel pump can't work.
Automatic starting: If setting up the black three-way switch to the "Auto" position on the control panel mode, it can receive an effective fire alarm signal to control the starting or stopping of the diesel pump. It can recieve the pressure signal of the pressure controller on the outlet pipe to achieve pressure control. First, use two 1" 1.5 square signal lines to connect the pressure controller normally open contacts and the control cabinet's terminal No. 111 and 127. Then, set the maximum value and the minimum value for the pressure controller to achieve low-pressure to start the pump and high-pressure to stop the pump. Finally, if the electric main pump is overloaded, the diesel engine pump will start.
