Frequently asked questions
Common questions about DEWAY from 3G Electric.
What battery types do DEWAY cordless fuel transfer pumps use?
DEWAY cordless fuel transfer pumps are available in two battery configurations. Models such as SKU 879DM1 and 879DM0 operate on D-size batteries at 1.5 V. Other models, including SKU 879DL8 and 879DL9, use AA-size batteries at 3 V. The battery type affects the pump's power source but not the maximum viscosity rating, which is 10 cps for all listed models. The pumps are designed for dry-cell batteries and do not include rechargeable battery packs or chargers. When selecting a model, consider battery availability and the desired flow rate, as AA and D configurations may have slightly different performance characteristics.
What is the maximum flow rate of DEWAY battery-operated pumps?
The maximum flow rate for DEWAY battery-operated pumps varies by model. SKU 879DM1, 879DM0, and 879DL8 are rated at 2.4 gallons per minute (gpm). SKU 879DL9 has a maximum flow rate of 2.2 gpm. These flow rates are measured under typical conditions with low-viscosity fluids and may vary with battery condition, fluid viscosity, and suction lift. The pumps are intended for intermittent transfer, not continuous duty, so actual delivered volume over time will depend on duty cycle and operating conditions. For precise sizing, refer to the individual product datasheet or contact 3G Electric for assistance.
What fluids can DEWAY cordless fuel transfer pumps handle?
DEWAY cordless fuel transfer pumps are designed for fluids with a maximum viscosity of 10 centipoise (cps). This includes gasoline, diesel, kerosene, light oils, and water-like liquids. The plastic suction tube and pump materials are compatible with these fluids, but users should verify chemical compatibility for any specific fluid, especially those containing additives or solvents. The pumps are not suitable for high-viscosity fluids, corrosive chemicals, or fluids that may degrade the plastic components. Always follow safety precautions when transferring flammable liquids, and ensure proper grounding and ventilation. For fluids outside the 10 cps limit, consider alternative pump technologies.
Are DEWAY fuel transfer pumps self-priming?
Yes, DEWAY cordless fuel transfer pumps are self-priming, meaning they can draw fluid from a container without manual priming. The included plastic suction tube is placed into the fluid, and the pump creates suction when activated. This design simplifies operation and reduces spillage compared to manual siphoning. However, priming time may vary with suction lift and fluid viscosity. The pumps are intended for transferring from open containers or drums, not from pressurized systems. Ensure the suction tube is fully submerged and free of debris to maintain priming performance. For best results, keep the pump and tubing clean and inspect regularly.
What is the maximum viscosity for DEWAY battery-operated pumps?
The maximum viscosity for DEWAY battery-operated pumps is 10 centipoise (cps). This rating applies to all listed SKUs, including 879DM1, 879DM0, 879DL8, and 879DL9. Fluids with viscosity above 10 cps may not pump efficiently or could cause damage to the pump mechanism. Viscosity is temperature-dependent, so a fluid that is within the limit at one temperature may exceed it at another. For example, some oils thicken as they cool. Always check the fluid's viscosity at the intended operating temperature. If you need to transfer higher-viscosity fluids, consider a positive displacement pump or a model rated for higher cps.
Can DEWAY cordless fuel transfer pumps be used with diesel and gasoline?
DEWAY cordless fuel transfer pumps are suitable for transferring diesel, gasoline, and kerosene, provided the fluid viscosity is at or below 10 cps. The plastic suction tube and pump materials are compatible with these fuels under normal conditions. However, gasoline and other flammable liquids require careful handling: use the pump in a well-ventilated area, avoid sources of ignition, and follow all local safety regulations. The pumps are not explosion-proof and should not be used in hazardous locations. For continuous or high-volume transfer, a stationary pump may be more appropriate. Always inspect the pump and tubing for signs of wear or chemical attack before use.
