Duplex II Demand Diaphragm Pump With Pressure Switch
The Flojet D3722V5011ARL is a Duplex II series diaphragm pump built for general industrial fluid handling. It uses a demand-style pressure switch to automatically stop flow when the discharge valve is closed and restart when pressure drops, and it is designed to be self-priming and tolerant of dry running for intermittent duty applications.

Product Details
- Typical uses mentioned include liquid transfer, spraying, cooling, circulation, filtration, and dispensing.
- For best protection against debris, the inlet line should use a minimum 40 mesh strainer or filter.
- If a check valve is installed in the plumbing, it should have a cracking pressure of no more than 2 PSI (0.14 bar) to avoid affecting priming performance.
- Not intended for pumping flammable fluids (gasoline, kerosene, fuel oil) and not for use in explosive environments.
- The motor is described as a permanent magnet type with a solid state rectifier and full RFI suppression.
