This is a pump-only unit — no motor, no tank, no base. You supply the motor and mount the pump into your compressor package. At 7.5-10HP with two-stage compression and a V4 cylinder layout, this pump is built for sustained high-demand applications: multi-bay auto shops, fleet maintenance facilities, body shops with continuous spray gun demand, and light manufacturing with multi-tool pneumatic circuits.\u003c\/p\u003e\n\n\u003cp\u003eThe V4 cylinder arrangement — four cylinders in a V configuration — provides more displacement per revolution than a 2-cylinder design, which is how Cast Air can cover the 7.5-10HP motor range with good volumetric efficiency. Two-stage compression means the air is compressed in two steps with intercooling between stages, which reduces discharge temperature and moisture carryover compared to single-stage designs at equivalent pressures.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7.5-10HP Motor Compatibility:\u003c\/strong\u003e Wide HP range gives flexibility in motor selection for rebuilds and new builds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Stage Compression:\u003c\/strong\u003e Two-step compression with intercooling — lower discharge temps, reduced moisture in compressed air, better efficiency at higher pressures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eV4 Cylinder Configuration:\u003c\/strong\u003e Four cylinders in a V arrangement for high displacement in a compact package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCast Iron Construction:\u003c\/strong\u003e Cast iron cylinders and valve seats for long service life under commercial duty cycles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlywheel Included:\u003c\/strong\u003e Flywheel for V-belt drive connection — verify groove and diameter specifications for your motor pulley match\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBare Pump:\u003c\/strong\u003e Motor, tank, and base not included — you configure the complete compressor package\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump Type:\u003c\/strong\u003e Two-stage reciprocating, V4 cylinder arrangement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Compatibility:\u003c\/strong\u003e 7.5 to 10HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Material:\u003c\/strong\u003e Cast iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e V-belt via flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003eCFM output, max working pressure, flywheel OD, belt groove specifications, RPM range, oil capacity — contact us for complete specifications.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhen the C2 Is the Right Pump\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump Replacement:\u003c\/strong\u003e Original pump is worn or failed; the motor, tank, and frame are serviceable — replace just the pump head with the C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew Build, 7.5-10HP Range:\u003c\/strong\u003e Spec'ing a custom compressor for a specific application — the C2 is the pump for this HP range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Bay Auto Shop:\u003c\/strong\u003e 7.5-10HP two-stage output handles simultaneous impact wrenches, air ratchets, and tire equipment across multiple bays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shop with Continuous Spray Demand:\u003c\/strong\u003e Two-stage efficiency and adequate CFM for sustained spray gun use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFleet Maintenance:\u003c\/strong\u003e High-duty-cycle environment where continuous-run performance and pump longevity matter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eC1 vs. C2 vs. C3 — Choosing the Right Pump\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eC1 (4-7.5HP, inline 2-cyl):\u003c\/strong\u003e Single-bay shops, light commercial, moderate duty cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC2 (7.5-10HP, V4):\u003c\/strong\u003e Multi-bay shops, body shops, fleet maintenance, higher duty cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC3 (15HP, W3):\u003c\/strong\u003e Large multi-bay facilities, production shops, continuous heavy demand\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From OEM Diagnostic Tools?\u003c\/h3\u003e\n\u003cp\u003eWe stock Cast Air bare pumps and compressor components for commercial shops and industrial applications.
