AEM Water/Methanol Injection 200psi Recirculation Pump

AEM 200 PSI Water/Methanol Injection Recirculation Pump | High Performance

Upgrade or replace your water/meth system with the AEM 200 PSI Recirculation Pump. Features internal bypass technology, Santoprene diaphragm, and whisper-quiet operation.

The AEM Water/Methanol Injection 200 PSI Recirculation Pump is designed for forced-induction, high-compression, and turbocharged performance applications. Engineered with an innovative internal bypass mechanism, this pump bypasses pressure internally to eliminate the rapid, erratic cycling and pulsing associated with traditional pressure-switch-driven pumps.

Constructed with high-grade chemical resistance in mind, it utilizes a durable Santoprene diaphragm and EPDM seals, allowing it to safely withstand water and alcohol mixtures up to 50% concentration. By outputting up to 200 PSI, it ensures ultra-fine fluid atomization through injection nozzles, delivering maximum cooling to intake air temperatures and boosting effective octane ratings.

Best Uses

1. Direct Replacement / Upgrade: Ideal replacement pump for AEM Water/Methanol Injection Kits (PN 30-3015 / 30-3018) or custom DIY water/methanol setups.
2. Knock & Detonation Suppression: Excellent for high-boost, high-heat applications where suppressing knock and lowering charge-air temperatures are critical.
3. Octane Enhancement: Allows aggressive ignition timing and higher boost levels on standard pump gas without engine knock.
4. Carbon Build-up Reduction: Helps clean and suppress carbon deposits on intake valves and pistons in direct-injection engines.

Features

1. Internal Bypass Recirculation Design: Eliminates harsh pulsing and erratic pressure switching, ensuring smooth, linear, and consistent fluid pressure delivery across all duty cycles.
2. 200 PSI High-Pressure Output: Delivers high operating pressure to atomize fluid mixtures into a fine mist for optimal thermal absorption and injection efficiency.
3. Alcohol-Resistant Construction: Built using a heavy-duty Santoprene diaphragm and EPDM seals designed for long-lasting chemical compatibility with water and methanol mixtures.
4. Quiet & Smooth Operation: Advanced dampening and internal bypass technology significantly reduce vibration and operating noise compared to standard diaphragm pumps.
5. Integrated Mounting Flange: Features an integrated bracket/flange design for secure, straightforward mounting in any horizontal or vertical orientation.

Benefits

1. Prevents Engine Detonation: Drops intake air temperatures substantially, allowing aggressive spark timing and higher boost levels without knock.
2. Ultra-Consistent Injection Flow: Prevents fuel mixture spikes and pressure dips caused by traditional pressure switch cycling.
3. Quiet & Smooth Operation: Advanced bypass design eliminates loud pulsing, offering quieter performance inside the cabin.
4. Long-Lasting Reliability: Methanol-compatible seals prevent degradation, leaks, and premature pump failure.
5. Universal Compatibility: Integrates easily into custom plumbing or existing water/meth injection systems via standard push-lock or NPT fittings.
