Flotide/MEGA Filtration System FSB450 exploded view & spare parts

Flotide/MEGA Filtration System FSB450 exploded view & spare parts

This page provides the full exploded-view diagram and parts list for the Flotide/MEGA Filtration System FSB450 — a side-mount sand filtration combo marketed under both the Flotide/MEGA and MEGA brands. The FSB450 pairs an 18-inch filter tank with the Flotide/MEGA SS075 centrifugal pump and a 1½-inch multiport valve, forming a complete circulation and filtration unit suited to domestic in-ground and above-ground pools. No factory part numbers separate to those listed in the BOM below have been assigned to this model. Use the diagram and the numbered parts list on this page to identify the exact component you need in a matter of minutes.

Come utilizzare lo schema numerato per individuare il proprio componente

Every numbered call-out in the exploded-view diagram corresponds directly to a numbered row in the parts list table below the image — start by locating the area of the unit where you see the fault or wear, then find the matching number on the diagram. Once you have the position number, cross-reference it in the table to retrieve the item description and SKU, which is the reference you will need when adding the part to your basket. Work methodically from the top of the unit downwards: the head assembly (positions 1–6) sits above the tank body (positions 7–16), with the pump and base hardware at positions 17–18. Bear in mind that a single position number may appear in more than one location on the diagram — position 13, for example, covers the lateral collector arms, of which there are typically several fitted at the same level inside the tank. If a position number appears with a letter suffix on any printed version of the diagram (such as 10a or 10b), treat each lettered variant as a distinct component; selecting the wrong lettered variant is one of the most common ordering errors on multi-part inner assemblies. Finally, note that some positions in this BOM do not yet carry a live SKU — these are shown as unavailable in the table; contact our team if you need guidance on sourcing those items.

Main replaceable assemblies on the Flotide/MEGA FSB450

The FSB450 breaks down into four broad service areas, each visible as a distinct cluster in the exploded diagram. The valve head assembly — positions 1 through 6 — sits at the very top of the unit and contains the components most frequently disturbed during routine maintenance: the air release valve (pos. 1, SKU 7009344) vents trapped air after backwashing, while the oil pressure gauge (pos. 2, SKU 7009342) and its dedicated connector (pos. 3, SKU 7009306) give a continuous read-out of filter pressure so you know when a backwash cycle is due. The cover (pos. 4, SKU 7009314) protects the valve internals, and the band clamp (pos. 5, SKU 7009347) together with the tank O-ring (pos. 6, SKU 7009338) form the pressure-tight seal between the valve head and the filter tank body — the O-ring is a frequent service item and should be inspected whenever the head is removed. The filter tank and inner distribution system occupies positions 7 through 13: the tank body itself (pos. 7) connects to the 1½-inch side-mount multiport valve (pos. 8, SKU 0891915) via the 1.5-inch connector plate (pos. 9), and internally the water is distributed by the top part of the inner tank system (pos. 10), the tank system support (pos. 11), and the bottom collector (pos. 12). The 115 mm laterals at position 13 (SKU 7009308) are the slotted arms that hold and drain the filter media — these are a known wear item and are available individually. The base and drainage group covers positions 14 and 15: the water drain set (pos. 14, SKU 7009343) allows the tank to be fully emptied for winter lay-up, and the combo base (pos. 15) provides a stable platform for the whole assembly. The pump and connecting hardware at positions 16–18 completes the system: the hose with nut (pos. 16, SKU 7010627) links the pump outlet to the valve, the Flotide/MEGA SS075 pump (pos. 17, SKU 0950089) is the centrifugal unit that drives circulation, and the filter base fastener set (pos. 18) secures the pump-filter frame to its mounting surface.

Scelta tra varianti e formati di confezione

Several components in this diagram serve structurally similar but dimensionally distinct roles, so confirming the correct variant before ordering is important. The laterals at position 13 are specified at 115 mm in this BOM; laterals are available in multiple lengths across the Flotide/MEGA filter range, and fitting a lateral of the wrong length can leave gaps in media coverage or prevent the collector from seating properly. The water drain set (pos. 14) and the connector for the pressure gauge (pos. 3) both involve threaded fittings — always check the thread pitch and connection diameter against your existing pipework before ordering, as an incorrect thread form will not seal reliably regardless of how tightly it is tightened. If the diagram on your printed manual carries lettered suffixes for any inner tank parts (for example, distinguishing a short-run support from a full-length version), treat each suffix as a separate SKU requirement and order accordingly. Where a position covers a set of identical small parts — such as fasteners at position 18 — the pack quantity is noted in the description; ordering a single fastener where a set of four is required is easily avoided by reading the description in full before adding to your basket.
