Flojet Duplex II Demand Pump - 12V D3134B5011AR

Demand Operation is considered an “intermittent duty” application. The maximum intermittent duty cycle is that which will cause the motor to reach its maximum thermal limits. Once the maximum thermal limit is reached, the motor must be allowed to settle to a lower temperature ideally being ambient before resuming operation. Running the pump at or near the maximum thermal limit for extended period of time will shorten the life of the pump and may result in immediate pump failure.

The Flojet Duplex II Series diaphragm pumps incorporate the best technology and features developed by Flojet. Everything from the back-flow preventer, check valves, bearings and diaphragm assembly to the motor, has been designed to make this the most reliable diaphragm pump available.
Highly efficient, this pump boasts a long life thanks to the motor pump unit, and the diaphragm design combined with the check valves makes the pump capable of pulling higher dry vacuum.
The Duplex II Series is available in various performance ranges and voltages, and with a choice of elastomers, making it easily adaptable to a diverse range of applications, including automotive use, chemical transfer, road compaction, agricultural spraying, construction, floorcare, and other general purpose applications.
