Flojet Pumps Agricultural Demand Pumps

Flojet Pumps are commonly used on a variety of spot sprayers and small estate sprayers with a single fixed or adjustable tip wand. Frequently a spot sprayer and a small boom sprayer are combined on the same rig.

Suitability for the application should be determined by actual use and is the full responsibility of the customer. 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. Data shown is based on the results at ambient temperatures, unless otherwise noted. Agricultural Products Chemical Resistance Test Data

  • The polypropylene pump housing material is resistant to a wide range of chemicals and is generally suitable for most applications. Five elastomer materials are available (all suitable for pumping water):
  • EPDM: Resistance to a wide range of chemicals for general purpose use.
  • Santoprene: EPDM and Santoprene have similar chemical characteristics. Where data is not shown for Santoprene, the data for EPDM may be used as a guide.
  • Buna N: Generally suitable for oils, oil based liquids and oil emulsions.
  • Geolast: suitable for light fraction hydrocarbons and solvents. Buna and Geolast have similar chemical characteristics. Where data is not shown for Geolast, the data for Buna may be used as a guide.
  • Viton: Generally resistant to many acids and some solvents, has good high temperature properties up to 180 F but poor low temperatures performance below 50 F.

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

Frequently a spot sprayer and a small boom sprayer are combined on the same rig. Also one of the more popular agriculture uses for FLOJET pumps is for small boom sprayers. A spot spray wand attachments is often combined on the same rig

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.
