Waterstar spare parts: which part fits which pump, filter and valve
Every component of every product Waterstar makes is available as a spare part — from the same factory in Badr City, on the same fourteen-day lead time as the product itself. This page tells you which part fits which product, taken directly from the production bills of material rather than from a catalogue.
One rule before the tables: **no Waterstar part fits another manufacturer's product, and no other manufacturer's part fits ours.** Spider gaskets, impellers and seals look alike between brands; they are not interchangeable, and a wrong guess on a pressurised vessel floods a plant room.
## Pumps — SuperStar and HyperFlow, 1 to 3 HP
| Part | Code | Fits |
|---|---|---|
| Mechanical seal | SP-SEA-001 | **All eight pumps** — SuperStar and HyperFlow, 1–3 HP |
| Motor 1 HP / 1.5 HP / 2 HP / 3 HP | SP-MOT-002 / 003 / 004 / 005 | Both ranges at the same rating |
| Strainer basket — SuperStar | one part | All four SuperStars |
| Strainer basket — HyperFlow | one part | All four HyperFlows |
| Impeller, shroud, impeller housing | rating-specific | One per horsepower and per range |
| Diffuser — SuperStar | 3 sizes | 1 HP · 1.5 & 2 HP · 3 HP |
| Diffuser — HyperFlow | 2 sizes | 1 & 1.5 HP · 2 & 3 HP |
What that means in a service van: one seal part number and four motors cover every Waterstar pump in the field. The seal is the part that fails first on any pool pump.
## Sand filters — top-mount T500 to T1005 and commercial WS-1200 to WS-2000
| Part group | Fits |
|---|---|
| Drain valve (body, plug, nut, strainer, gasket), drain nozzle (body, cap, insert), clamp track and clamp gasket, sight-glass cover, tank neck collar — **16 part numbers** | **All ten filters**, 20" residential to Ø2000 commercial |
| Lateral hub, upper and lower — 50 mm | T500-20, T600-24 |
| Lateral hub, upper and lower — 63 mm | T750-30a up to WS-2000 (eight filters) |
| Lateral finger — small / medium / large | T500 · T600 & T750 · T900 and every commercial size |
| Tank halves and base | Size-specific, one set per diameter |
A broken lateral is the most common cause of sand in the pool. Stocking the large lateral finger alone covers seven of the ten filters.
Filters ship **without** media. Sand (0.4–0.8 mm) and, on commercial sizes, the 1–2 mm support gravel are ordered alongside the filter; the charge for each size is on its product page.
## Multiport valves — six-position, top-mount and side-mount, 1.5" and 2"
| Part | Fits |
|---|---|
| Rotor gasket, sight glass and gasket, pressure gauge, stainless spring, pin, plug, bolt set, washer set — **9 part numbers** | **All four valves** |
| Spider gasket 1.5" (SP-GAS-205) / 2" (SP-GAS-206) | Both 1.5" valves / both 2" valves — mounting does not matter |
| Rotor, lid, lid gasket, handle, strainer | By port size (1.5" or 2"), same for top and side mount |
| Valve body | One per valve — the only valve-specific part |
| Complete gasket kit | SP-GAS-292/293 (1.5" side/top), SP-GAS-294/295 (2" side/top) |
The spider gasket is the wear part: it is the star-shaped seal under the rotor that keeps the six positions apart. When it wears, water bypasses to waste and the gauge never settles.
## How to order
Send us the product code from the label (for example SS-150M, T750-30a, MPV-T-2) and the part you need, or a photo of the part. We confirm the part number and price by return and ship within fourteen days of confirmation — usually much sooner for wear items held in stock.
Full fitment charts for pumps, filters and valves, listing every part number, are available from our sales team on request.
