High Torque = High Flow

A fuel injected internal combustion engine is a dynamic system. Fuel flow requirements vary greatly by rpm and load. However, one law remains universal: forced induction applications require more flow at higher pressures. Knowing this fact, DW has engineered their fuel pumps to maximize flow at higher pressures. By designing the armature for torque bias, delaying pressure relief activation, and maximizing impeller efficiency, DW has created a line of pumps with an extremely flat flow curve. Higher flow at higher pressure delivers the fuel your engine demands.

Ethanol Compatibility

Today's ethanol-enriched fuels are more corrosive than the fuels of the past. High-octane premium grade pump gas can contain up to 15% ethanol and e85 is becoming increasingly popular as an inexpensive readily available race fuel. Regardless of what fuel you prefer, DW has specifically engineered their pumps with ethanol in mind…

  • Composite Impeller – DW turbine impellers are made of a lightweight composite that is both efficient and impervious to the corrosive nature of ethanol.

  • Encapsulated Armature – DW motor armatures are fully encapsulated to protect the copper windings from ethanol deterioration

  • Carbon Commutators and Brushes – The utilization of carbon in the wear components of the pump leads to a much longer life especially in high-heat and high-pressure conditions.

  • Endurance Testing – DW performs in-house HALT (highly accelerated life testing) on all pump designs and in various fuels to find and eliminate common modes of failure.

Even if you don’t use ethanol-enriched fuels, the extra work is not wasted. All of the above-mentioned design attributes translate to a more dependable longer life fuel pump regardless of the fuel used.

3 Year Comprehensive Warranty

DW is committed to high-quality products and excellent customer service. All products are backed up with a 3-year comprehensive warranty.  This warranty could not be offered without supreme confidence in product quality. As part of QA procedures, all pumps and all injectors are bench tested in-house before packaging and shipment to the customer.  Below is a brief over of the fuel pump testing process…
