It provides the primary mounting surface for the motor and pump assembly on tank-mounted reciprocating compressor configurations, sitting above the tank saddle and below the compressor pump and motor.\u003c\/p\u003e\n\u003ch2\u003eWhat a Base Mount Top Plate Does\u003c\/h2\u003e\n\u003cp\u003eIn a tank-mounted reciprocating compressor, the motor and pump do not bolt directly to the tank. They mount to a base plate assembly that spans the top of the tank saddle. The top plate is the flat structural member that accepts the motor mounting feet and pump mounting bolts. It carries the dynamic loads from the running compressor — the vibration, torque reactions, and weight — and distributes them into the tank structure.\u003c\/p\u003e\n\u003cp\u003eWhen this plate fails — through corrosion, cracking, or physical damage — you need an exact-size replacement to restore the mounting geometry. The BM13X40 is the correct replacement for Castair units built on the 13\" x 40\" base mount specification.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e BM13X40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 13\" x 40\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Base Mount Top Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Major Components — Tanks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e13\" x 40\" Dimensions:\u003c\/strong\u003e Correct fit for Castair compressors built on the 13x40 base mount platform — larger than BM12.5x32, smaller than BM17x44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Integrity:\u003c\/strong\u003e Built to carry the mounting loads of motor and pump assemblies through continuous-duty compressor operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Replacement:\u003c\/strong\u003e Correct Castair part number for this base mount size — matches original mounting hole patterns and material specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReplacement base mount top plate for Castair compressors built on 13\" x 40\" base mounts\u003c\/li\u003e\n\u003cli\u003eCompressor rebuilds and refurbishments where the base mount has corroded or been damaged\u003c\/li\u003e\n\u003cli\u003eIndustrial compressor repair where maintaining OEM mounting geometry is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBase Mount Size Reference\u003c\/h2\u003e\n\u003cp\u003eCastair makes base mount top plates in multiple sizes to match different compressor configurations: BM9.5x25 (9.5\" x 25\"), BM12.5x32 (12.5\" x 32\"), BM13X40 (13\" x 40\"), BM17x44 (17\" x 44\").
