The Flojet D21X007B Duplex II diaphragm pump is a 12V DC unit with a 50 PSI pressure bypass and an external bypass system that internally bypasses flow when pressure exceeds 50 PSI. It features a polypropylene body, Viton diaphragm, and Santoprene check valve, with 3/8 inch NPT female inlet and 3/8 inch NPT female discharge ports. The pump is self-priming up to 8 ft (2.4 m), can run dry without damage, has a maximum temperature of 140°F, and weighs 5 lbs; it is intended for intermittent duty cycles rather than continuous duty service.

Duplex II 12V DC Diaphragm Pump With 50 PSI Bypass
The Flojet D21X007B is a Duplex II series diaphragm pump designed for a wide range of liquid handling tasks such as transfer, spraying, cooling, circulation, filtration, and dispensing. It uses an external bypass system to bypass flow internally when system pressure exceeds its bypass setting, and it is built with materials selected for handling a broad range of chemicals.

Features
- Self-priming design capable of pulling higher dry vacuum
- Can run dry without damage
- External bypass system bypasses flow internally when pressure is over 50 PSI
- Pump head can be rotated in 90 degree increments to simplify plumbing
Product Details
- Designed to run until power is manually turned off
- Not recommended for continuous duty service due to limited motor brush life; intended for intermittent duty cycles (can be run continuously for short periods)
- Typical uses include liquid transfer, spraying, cooling, circulation, filtration, and dispensing; generally used for agricultural applications
- Do not use to pump flammable fluids (including gasoline, kerosene, fuel oil) and do not use in an explosive environment
- If a check valve is installed in the plumbing, cracking pressure must be no more than 2 PSI (0.14 bar)
- Use of a minimum 40 mesh strainer or filter in the inlet line is recommended to help prevent debris from entering the pump
- Mount in a dry, adequately ventilated area; for outdoor mounting, shield from water, dust, sunlight, and wash down spray
- On 12V DC wiring: red lead is positive and black lead is ground; use T6 AWG wire minimum and use a fuse to protect system wiring and components
