I now have enough context to write accurate, well-grounded copy. Here is the HTML:<\/p>\n
This page covers the complete exploded-view diagram and bill of materials for the Davey ProMaster VSD200 and VSD400 variable-speed pool pumps with Bluetooth, sold under factory references SP200BT<\/strong>, SP400BT<\/strong>, SP200SV<\/strong> y SP400PV<\/strong>. The diagram illustrates every serviceable component across both pump sizes \u2014 from the inlet barrel unions right through to the rear endshield and motor internals. Because the VSD200 and VSD400 share the same fundamental architecture, the two models largely share a common diagram; where a part differs between sizes, separate line entries make the distinction clear. Use the numbered call-outs and the parts list below to identify exactly what you need in minutes, without having to request a paper parts manual.<\/p>\n Every circled number on the diagram corresponds directly to a numbered row in the parts table below it \u2014 locate the area of the pump that concerns you (wet end, motor housing, drive electronics, or rear cover), then trace the call-out number to its matching row to find the part description and SKU. Once you have the SKU, simply enter it into the search bar or add it straight to your basket. Bear in mind that some position numbers appear more than once in the table: this is intentional and reflects genuine differences between the two pump sizes rather than a printing error. For example, position 1 lists two separate barrel union assemblies \u2014 a 50 mm version for SP200 models (SKU 33204SP<\/strong>) and a 63 mm version for SP400 models (SKU 48722B-1SP<\/strong>) \u2014 so always confirm your pump’s factory reference before ordering. Similarly, position 11 carries two impeller assemblies and position 25 carries two stator-and-shell assemblies, each matched to either the SP200 or SP400 platform. Position 16 likewise lists two distinct top-casing assemblies, one for SP200BT and one for SP400BT. When a position number does not appear in this BOM (position 12 is absent, for instance), that item is either a sub-component already included within an assembly or is not offered as a standalone spare. If you are uncertain, the part description column will tell you whether an assembly already includes sub-components, saving you from ordering duplicates.<\/p>\n The wet end begins at the inlet connections: position 1 is the barrel union assembly, which comprises the union nut, tail piece and o-ring as a single unit, and is the first seal between your pipework and the pump body. The strainer pot is formed by the casing front (position 7) sealed against the pump body via the casing o-ring (position 8); the transparent lid and its x-ring (position 3) and the x-ring alone as a service item (position 4) allow the pot to be opened for routine basket clearing, while the strainer basket itself is position 5. The priming plug and o-ring (position 6) provide a convenient priming point on the casing front. Water then passes through the diffuser (position 9) and over the floating neckring (position 10) before reaching the impeller assembly at position 11 \u2014 a threaded impeller unit that differs between the SP200 and SP400 platforms. The all-important mechanical seal at position 13 (a 5\/8" shaft seal, SKU 49771SP<\/strong>) sits immediately behind the impeller and is one of the most commonly replaced wear items on any centrifugal pump; the o-ring at position 14 works in conjunction with it. The motor section begins with the motor jacket and water shell (position 15), which forms the water-cooled shroud that gives this pump its notably quiet operation. The variable-speed drive electronics are housed within the top casing assembly at position 16 \u2014 a model-specific sub-assembly that includes the VSD board and must be matched precisely to either the SP200BT or SP400BT. The motor internals comprise the stator and shell assembly (position 25), the rotor assembly (position 27), the bearing kit (position 26), and the endshield (position 28), with the rear of the motor closed by the bottom casing (position 19) and its gasket (position 18).<\/p>\n Several positions in this BOM carry model-specific variants, and selecting the wrong one will result in a part that does not fit. For positions 1, 11, 25, and 27 the determining factor is your pump size: check whether your unit carries the SP200 or SP400 factory reference (found on the data plate, usually on the motor housing) and select accordingly. Position 16, the top casing assembly including the VSD, is differentiated even further \u2014 SKU 32983SP<\/strong> is for the SP200BT and SKU 32978SP<\/strong> is for the SP400BT \u2014 making an exact factory reference match essential before ordering this higher-value assembly. Position 19, the bottom casing, also splits by model family: SKU 15071<\/strong> fits the SP200SV and SP400PV, while SKU 15071-2<\/strong> is correct for the Bluetooth variants SP200BT and SP400BT. Where hardware items such as the heatsink screws (position 17), bottom casing screws (position 20), and the rear cover screw kit (position 30) are listed, note that these are supplied as sets; ordering a single screw kit covers the full fastener count for that assembly, so there is no need to count individual fixings before placing your order.<\/p>","protected":false},"excerpt":{"rendered":"C\u00f3mo utilizar el esquema numerado para localizar tu pieza<\/h3>\n
