DEWAY
Frequently asked questions
Common questions about DEWAY from 3G Electric.
What battery types do DEWAY fuel transfer pumps use?
DEWAY pumps are available in two battery configurations: AA size (3 V total, using two AA cells) and D size (1.5 V, using a single D cell). The AA models (WAYPUMP11, WAYPUMP12) provide 2.2–2.4 gpm flow, while D-cell models (WAYPUMP14, WAYPUMP15) deliver 2.4 gpm. Battery type affects runtime and availability; D cells typically offer longer continuous operation due to higher capacity, but AA cells are more universally stocked. Neither configuration uses rechargeable batteries, so replacement is straightforward.
What is the maximum viscosity DEWAY pumps can handle?
DEWAY battery-operated pumps are rated for fluids with a maximum viscosity of 10 centipoise (cps). This covers light fuels such as diesel, kerosene, gasoline, and thin hydraulic oils. Fluids with higher viscosity, such as heavy gear oils or grease, will not flow reliably through the pump and may cause motor stall or damage. For thicker fluids, a different pump class (e.g., air-operated or AC-powered diaphragm pumps) would be required.
Are DEWAY pumps suitable for continuous-duty transfer operations?
No. DEWAY pumps are designed for intermittent, low-volume transfer tasks. Their duty cycle is limited by battery life and the thermal capacity of the DC motor. Continuous operation beyond a few minutes may cause overheating or premature battery drain. Typical use cases include refueling small engines, transferring fuel from drums to portable tanks, or emergency siphoning. For high-volume or continuous pumping, consider AC-powered or 12 V DC pumps with higher flow ratings.
What is the maximum flow rate of DEWAY cordless pumps?
DEWAY pumps offer maximum flow rates of 2.2 gpm (AA models WAYPUMP11 and WAYPUMP12) and 2.4 gpm (D-cell models WAYPUMP14 and WAYPUMP15). Actual flow rate depends on fluid viscosity, suction lift height, and discharge head. These rates are measured under low-head conditions with light fuels. Higher discharge heads or thicker fluids will reduce flow proportionally.
Can DEWAY pumps be used with gasoline or other flammable liquids?
Yes. DEWAY pumps are battery-operated and do not produce sparks from brushes or AC motors, making them suitable for transferring flammable liquids such as gasoline, diesel, and kerosene. However, the pump body and suction tube are plastic, so static grounding precautions should still be observed. Always follow local safety codes and use bonding wires when transferring fuel into metal containers. The pump is not rated for use in explosive atmospheres.
What is the suction tube material on DEWAY pumps?
DEWAY pumps are equipped with plastic suction tubes. The plastic construction provides chemical resistance to common fuels and reduces weight for portability. The tube is rigid enough to maintain shape during insertion into drums or tanks but should not be used with fluids above 60°C or with aggressive solvents that may attack the plastic. The tube length is fixed and not user-replaceable on standard models.
