Our widely successful “Dorch Stage 2” (DS2) has been replaced with our latest and greatest creation; the DS25. This new pump is our “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the pump packaging to provide improved hose routing for even easier installations. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.\u003c\/p\u003e\n\u003cp\u003eWhat does this mean? It means the most reliable and highest flowing N55 pump on the market just got even MORE reliable and even MORE flow!
