Axial/Mixed Flow Pumps PP 4600 Series Pumps: The Flygt PP-4600 pump series was developed for pumping of large volumes of water in municipal and industrial applications, amusement park rides, storm water, and any application for low to medium head pumping of partially screened clean or contaminated water. The PP-4600 propeller pump series compliments Flygt's PL-7000 series of electric submersible propeller pumps by providing a range of horizontally mounted, axial discharge pumps, with lower discharge head capabilities than that of the PL-propeller type pumps. Description The fundamental design of the PP-4600 series pump, combines Flygt's heavy duty, electric, submersible motor unit, with a solids handling propeller and bell shaped inlet. The PP-4600 series propeller pump is installed by simply lowering the integral motor/pump unit, down into the pump basin along a guide rail system, and onto its discharge connection.
The pump seals itself against the discharge connection by virtue of its own weight. Since no bolts or other fastening devices are required for installation of the PP-4600 series pumps, removal for inspection and service is easy. All that is necessary, is to lift the pump/motor unit up out of the pump basin along the guide rails.

The advantage to this is that there is no need for personnel to enter the pump basin. PL 7000 Series Pumps: The Flygt PL-7000 pump series was developed for the pumping of large volumes of clean and raw water for use in marine applications, secondary and final effluent, amusement park rides, stormwater, and any application for low to medium head pumping of screened, and lightly contaminated water.The PL-7000 propeller pump series compliments Flygt's LL-3000 series of electric submersible mixed flow pumps by providing a range of tube-mounted, axial discharge pumps, with a greater pump volume capacity than that of the mixed flow type pumps. Description The basic design of the PL-7000 series pump is a combination of the standard line of Flygt heavy duty electric submersible motor units directly coupled witha three or four bladed propeller which utilize a diffuser having three or more guide vanes to stabilize the discharge flow. The PL-7000 series propeller pump is installed by simply lowering the one piece motor/pump unit into its discharge column pipe and onto the pump mounting plate. The weight of the motor/pump unit firmly seats the pump to its mounting plate. Removal for inspection is extremely simple - just lift the pump/motor unit up/out from within the pump discharge column pipe. There is no need for pump forebay or wetwell entry to conduct a pump inspection.
LL/NL 3000 Series Pumps: The Flygt LL/NL-3000 pump series was developed forthe pumping of large volumes of raw water for use in marine applications, secondary and final effluent, amusement park rides, stormwater, and any application for low to medium head pumping of partially screened, contaminated water. The LL/NL3000 mixed-flow pump series compliments Flygt's PL-7000 series of electric submersible propeller pumps by providing a range of tube-mounted, axial discharge pumps, with a greater discharge head capability than that of the propeller type pumps. Description The basic design of the LL/NL3000 series pump is a combination of the standard line of Flygt heavy duty electric submersible motor units directly coupled with solids handling, mixed-flow impellers which utilize a diffuser having three or more guide vanes to stabilize the discharge flow. This diffuser is used in lieu of a centrifugal pump volute. This series of pumps includes an 'N' impeller feature that allows the pumps to reliably excel when handing large quantities of fibrous and stringy materials. The LL/NL3000 series mixed-flow pump is installed by simply lowering the one piece motor/pump unit into its discharge column pipe and onto the pump mounting plate.
Submersible Wet Well Pumps
The weight of the motor/pump unit firmly seats the pump to its mounting plate. Removal for inspection is just as easy, as you need only lift the pump/motor unit up/out from within the pump discharge column pipe.
