Image source & limitations
SC-300-series reference image from supplied materials, originally named with an L suffix. It does not verify the exact SC-300 configuration. Confirm the nameplate, drawing and duty requirements before ordering. Dongli watermark added for presentation. This series image is shared with related catalogue entries; original manufacturer markings are retained.
What the source says
The SC-300-specific engineering page in the supplied Pentair / MYERS APLEX manual records a 4.25 in stroke, pressure lubrication and a nitrided forged-steel crankshaft. Its power-end ratings are explicitly described as intermittent in that page.

About this reference
SC-300 pump reference — reference SC-300. This entry is organized under APLEX / SC-300 using the supplied documentation. The source reference identifies a catalog entry; it does not establish interchangeability or current availability. This pump entry supports equipment identification and configuration enquiries. Selection requires a documented operating point and a confirmed supply scope, including whether the drive and accessories are included. The SC-300 page describes a one-piece cast-iron power frame and field-removable stuffing boxes in aluminum bronze B148-C955 or 1020 carbon steel. It lists chromium-oxide-coated 416 or 316 stainless plungers and several packing options; these descriptions do not confirm the materials of a quoted pump. Keep the base SC-300 configuration separate from SC-300L and SC-300H. The engineering page and the separate sizing catalogue do not agree on the plunger-size range, so this entry does not publish that range or combine pressure and flow limits. Confirm the full nameplate, document revision, installed fluid-end components and intended duty before selecting a replacement or pump package.
Selection & verification
Provide the nameplate, required flow and pressure, fluid, drive speed and installation envelope for selection.
