Sta-Rite Pool Pump Supermax S5P1R exploded view & spare parts

Sta-Rite Pool Pump Supermax S5P1R exploded view & spare parts

This page covers the full exploded-view diagram and bill of materials for the Sta-Rite Supermax S5P1R pool pump — a self-priming, single- and three-phase pump available in output ratings from 0.37 kW through to 2.20 kW, identified by the factory model codes 5P1RC through 5P1RH. The S5P1R is a well-established pump in the European market, built around a heavy-duty TEFC (Totally Enclosed Fan Cooled) ATB motor paired with thick-walled hydraulic body parts and a tool-free Cam & Ramp locking lid. The diagram shows every serviceable component across all power variants in a single drawing, with lettered and numbered suffixes used to distinguish parts that differ between pump sizes. Whether you are chasing a water leak, replacing a worn impeller, or renewing a strainer basket, you should be able to identify your exact part number and SKU within a few minutes using the guide below.

Com utilitzar el diagrama numerat per trobar la teva peça

Every numbered call-out on the diagram corresponds directly to a row in the parts list beneath it — locate the area of the pump where your fault lies, find the nearest call-out number, then match that number to the parts list to obtain the correct SKU. Read the full description in the parts list carefully before ordering, because several position numbers carry lettered suffixes (for example, positions 1a through 1k for motors, 13a/13b for diffusers, and 15a through 15f for impellers) that denote variants for different power ratings — selecting the wrong letter will result in an incompatible part. Some positions represent a set quantity rather than a single item: position 9 (Bolt & Washer) is supplied as a set of four, position 12 (Screw) as a set of three, and position 14 (Bolt) as a set of four, so check whether you need to replace the entire set or just one piece. For positions where a sub-component has its own call-out (for example, position 1a1 is the capacitor belonging to motor 1a), trace the indented numbering carefully — ordering the sub-part alone is often sufficient without replacing the entire parent assembly. If a position shows no SKU in our parts list, please contact us directly, as that item may be supplied as part of a larger assembly or available on request.

Main replaceable assemblies on the Sta-Rite Supermax S5P1R

The motor assembly at position 1 (variants 1a–1k) is the heart of the pump, covering single-phase models from 0.37 kW (5P1RC-1) up to 2.20 kW (5P1RH-1) and three-phase equivalents (5P1RD-3, 5P1RE-3E2, 5P1RF-3E2, 5P1RG-3E2, 5P1RH-3E2); each single-phase motor variant has a matched capacitor listed as a sub-position (1a1, 1b1, 1d1, 1f1, 1h1, 1j1) which can be replaced independently without disturbing the motor itself. The seal plate including mechanical seal sits at position 2, and the standalone mechanical seal is also available separately at position 17 (SKU 7010700), giving you the option to reseal the pump without removing the entire plate. The pre-filter pot consists of the housing at position 7 (BSP black, SKU 7012215), the transparent lid at position 5 (SKU 7010689), and the locking ring at position 4 (SKU 7010693) — together these form the Cam & Ramp strainer chamber that gives the S5P1R its tool-free access. Sealing integrity in this area depends on the lid O-ring at position 6 (SKU 7010710), which should be inspected every season and is one of the most common sources of air ingress on this pump. The strainer basket at position 18 (SKU 7010650) sits inside the housing and is subject to UV and chemical degradation over time, making it a routine service item. The diffuser at position 13 is split into two variants: 13a covers motors from 0.37 kW to 1.10 kW (5P1RC–5P1RF), while 13b is specific to the higher-output 1.50 kW–2.20 kW models (5P1RG–5P1RH). Similarly, the impeller at position 15 has six variants (15a–15f), each matched to a specific motor power rating, secured by the impeller lock screw at position 16. The drain plug and O-ring assembly at position 8 (SKU 7010658) provides a serviceable winterisation point at the base of the volute.

Choosing between variants and pack sizes

The most critical variant selection on this pump is matching the power rating of your motor to the correct impeller (positions 15a–15f) and diffuser (13a or 13b), as each pairing is hydraulically engineered for a specific flow curve — fitting an impeller from a lower or higher power variant will reduce performance and can place undue load on the motor. For single-phase motor owners, the capacitor sub-positions (1a1 through 1j1) must equally be matched to the correct motor code; for example, position 1a1 is a 12.5 μF capacitor for the 5P1RC-1 motor, whereas position 1f1 is a 31.5 μF unit for the 5P1RF-1 — these are not interchangeable. The union kit at position 19 comes in two pipe sizes: 19a is a 50 mm metric union kit (SKU 7010714) and 19b is a 1‑1/2″ BSP imperial kit — measure your existing pipework before ordering to confirm which standard your installation uses. For fastener sets (positions 9, 12, and 14), the BOM quantity shown reflects the number of fixings required for a complete assembly; always replace the full set when reassembling to ensure even clamping and a reliable seal across the volute face.
