Flojet Duplex II Demand-Duty Diaphragm Pump Assembly
The Flojet D3935H5011 is a Duplex II diaphragm pump built for intermittent demand operation in industrial-style applications such as liquid transfer, spraying, cooling, circulation, filtration, and dispensing. It uses an integrated pressure switch to automatically stop flow when discharge pressure rises and restart when pressure drops, and it is designed to self-prime and tolerate short dry-running conditions.
