Flojet 4300 series pumps are suitable for a wide range of agricultural and industrial applications. With flow rates to 4.8 GPM and pressure to 45 PSI the 4300 series pump range is suitable for many applications and transfer of chemicals. The Flojet 4300-143 has an open flow rate of 4.8 GPM and is fitted with EPDM check valves and santoprene diaphragms.

The Flojet 4300 series is a self-priming pump. It is fitted with a 45 PSI pressure switch to provide “on demand” use and cut out. The build-in pressure switch also makes this a great pump for cottage potable water use.

It may be located several feet from the tank, above or below the liquid level (it is not a submersible pump). For vertical pump mounting be sure that the motor is located on top. This will prevent water from entering the motor chamber in event of a leak.
