Flojet Diaphragm Demand Pump 2 GPM 115V 100 PSI # D3835B7011A

Obsolete**not orderable** 2 GPM 100 PSI, Flojet 115V Model # D3835B7011A Spec. # MPU 115V B/B 3C SW100 Self Priming Automatic Demand Water Pump. These self priming double diaphragm pumps have a built-in pressure switch that will automatically start and stop the pump instantaneously when a discharge valve is opened and closed.

Suitability for the application should be determined by actual use and is the full responsibility of the buyer. No warranty, expressed or implied, can be extended by the equipment manufacturer where failure is caused by chemical attack on pump materials. Temperature, aeration, concentration, and other factors may change the effect of the specific fluid on the pump materials. Only pumps with Santoprene / EPDM elastomers are recommended for potable water. Units are NOT designed for permanent residential domestic water applications.

Do not assume chemical compatibility.
If the fluid is improperly matched to the pumps Elastomers,
the pump may fail to prime, leak, have low pressures
or the pressure switch may not shut off.

Questions & Answers

What is the Flojet Pumps duty cycle?: The Flojet manual states Intermittent duty. Can be run continuously for short periods of time. The higher the duty cycle the shorter the expected life of the pump.
Can Flojet Pumps run continuously?: Can be run continuously for short periods of time. The higher the duty cycle the shorter the expected life of the pump.
What does short periods of time mean?: Up 60 minutes with discharge pressure of up to 20 PSI. Up to 20 minutes when the discharge pressure is over 20 PSI. The off-time should be the same or more than the run time.
What is meant by demand operation?: Demand Operation is considered an “intermittent duty” application.
What is an intermittent duty cycle?: 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.
What diaphragm and valve materials are recommended by Flojet for potable water?: Only pumps with Santoprene / EPDM elastomers are recommended for potable water.
Are Flojet pumps recommended for permanent residential domestic water applications?: Units are NOT designed for permanent residential domestic water applications.
