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.
