Franklin Electric Centrifugal Self Priming Gas Engine Units FNSGF
Franklin Electric Centrifugal Self Priming Gas Engine Units FNSGF for High-Pressure Irrigation and Industrial Water Transfer
Franklin Electric Centrifugal Self Priming Gas Engine Units FNSGF are high-pressure self-priming centrifugal pump units built for demanding agricultural, construction, municipal, and industrial water transfer applications. Available through Ken’s Distributing Company at Kendisco, the FNSGF series handles flow rates up to 165 GPM and heads up to 185 feet, with a maximum working pressure of 120 PSI, making it the higher-pressure alternative to the FBSGF within the Franklin Electric gas engine self-priming pump lineup.
Where the FBSGF uses a semi-open impeller for handling dirty water and light solids, the FNSGF uses an enclosed cast iron impeller specifically designed for higher-pressure clean water applications. This enclosed impeller design, combined with a built-in check valve and diffuser, allows the FNSGF to achieve heads up to 185 feet, which is significantly higher than the 112-foot head capability of the FBSGF series.
The rugged cast iron volute features tapped openings for priming, venting, and draining. All units are equipped with industry-recognized engines from Kohler, Briggs and Stratton, and Honda with adjustable throttle controls and recoil starting. Diesel-powered variants are available through the FNSDF model designation for applications where gasoline fuel is not preferred. Ken’s Distributing Company at Kendisco stocks the full FNSGF lineup along with genuine Franklin Electric repair parts for all models.

Frequently Asked Questions
What is the Franklin Electric Centrifugal Self Priming Gas Engine Units FNSGF used for?
The Franklin Electric Centrifugal Self Priming Gas Engine Units FNSGF are designed for high-pressure water transfer in agricultural irrigation, construction dewatering, mining, municipal water supply, and commercial applications. The enclosed impeller design allows the FNSGF to achieve heads up to 185 feet, making it the right choice when a higher operating pressure is needed compared to the semi-open impeller FBSGF series. Ken’s Distributing Company at Kendisco stocks the full FNSGF lineup for fast order fulfillment.
What is the difference between the FNSGF and the FBSGF?
The most important difference between the FNSGF and the FBSGF is the impeller design. The FBSGF uses a semi-open impeller that handles dirty water, mud, sand, and silt up to 10 percent by volume. The FNSGF uses an enclosed cast iron impeller designed for higher-pressure clean water applications, allowing it to reach heads up to 185 feet compared to 112 feet for the FBSGF. If your application requires higher discharge pressure and the water source is relatively clean, the FNSGF is the better choice. If the water contains sediment or light solids, the FBSGF is more appropriate.
What engine options are available for the FNSGF?
The FNSGF is available with Briggs and Stratton INTEK, Honda OHV, and Kohler diesel engines. The Honda-equipped FNSGF-5H and FNSGF-8H models include low oil shut-off as standard. Diesel variants are available through the FNSDF model designation, including the FNSDF-5 with a Kohler KD350 6.7 HP engine and the FNSDF-8 with a Kohler KD420 9.8 HP engine. Consult the factory regarding parts support on diesel optioned units.
What connection sizes are available on the FNSGF?
The FNSGF-5 series models use 2 inch discharge and 2 inch suction NPT connections. The FNSGF-8 series models use 2 inch discharge and 2.5 inch suction NPT connections. The larger suction connection on the 8 HP class models reduces suction losses and supports the higher flow rates those engine sizes produce. Select the connection size based on your piping system, flow requirements, and the HP class you need.
What is the maximum head and flow rate for the FNSGF series?
At 5 feet of suction lift, the FNSGF-5 delivers up to 132 GPM at 10 PSI discharge pressure, with flow continuing at 52 GPM at 60 PSI. The FNSGF-8 delivers up to 165 GPM at 10 PSI discharge pressure, with flow continuing at 30 GPM at 80 PSI. The maximum head for the series is 185 feet, which is achieved by the enclosed impeller and diffuser design that sets the FNSGF apart from other gas engine self-priming pumps in the Franklin Electric lineup.
Are diesel engine options available for the FNSGF?
Yes. The FNSDF model variants are powered by Kohler diesel engines and are available in two configurations: the FNSDF-5 with a 6.7 HP Kohler KD350 engine (order 90274005) and the FNSDF-8 with a 9.8 HP Kohler KD420 engine available in two variants (order 90274008 without electric start and 90274108 with electric start and low oil shut-off). Diesel models are heavier than gasoline counterparts and consult the factory for parts support on diesel units.
