Over Speed Protection Device (Requied by NFPA)
Due to the engine overspeed can caused huge damages to engine itself, sometimes the parts inside of engine can be damaged and break out from engine block, can caused people injured. So NFPA20 standard have clearly requirement for the overspeed device, and this device should NOT be able to reset itself, have to be manually reset to avoid the difficulty of stopping engine. So we need additional A6: Air Intake Shut-Off Valve (Manual Reset): The design is shut off intake air, to make sure engine stop very fast at any working environment (Some enviroment can have combustible gas in the air which can make it difficult to shut down the engine by cut-off fuel supply). And need to have overspeed testing function in the fire pump control panel, NFPA20 required to run overspeed testing monthly.
As part of SinoMac, PumpMac provides abundant premium pump-driven power pack options, WPT PTO, Advance gearbox and pump head, as well as customized water pump set. We also have a set of NFPA20 standard engine power pack accessories including air intake shut-off valve, DC contactor, engine control panel, jacket water heater etc. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
If you are in need of pump model that not available on our website for the moment, please contact SinoMac sales team for technical details and related documents, our well trained sales and engineering team will help you with all products and techical documents available here at UL-listed.com.
The diesel engine overspeed cut-off valve must be installed on the engine’s intake pipe and can accommodate three installation methods.
