Practical guides on water pump categories, specifications and sourcing — from the TOPFENG team.
A portable washdown pump is a compact, battery-powered pump designed for flexible cleaning tasks where a plumbed water supply is not available. Typical specifications in this category include motor power from 50 W to 60 W, flow rates up to 6 L/min, and outlet pressures from 0.28 MPa up to 0.9 MPa depending on the model and configuration.
When comparing products, look at battery capacity (which determines runtime), charging options (Type-C, AC adaptor or car socket), self-priming height, and what accessories are included — hoses, sprayers and filters are often part of the kit. TOPFENG's WashGo series (TOPFENG2606, 2615 and 2616) covers different configurations in this category.
For B2B buyers evaluating cordless pressure washers, four specifications matter most: battery voltage and capacity, rated water pressure, flow rate, and what comes in the kit. In our current range, battery platforms are 21 V with capacities from 3000 mAh to 4.0 Ah, water pressures range from 1.5 MPa up to 30 Bar, and flow rates reach 4.0 L/min.
Tank-based models (like TOPFENG2604 with a 15 L tank) offer independence from a fixed water source, while kit-based models (like TOPFENG2603 and 2624) bundle batteries, chargers and cases. Always confirm which pressure gear or speed settings a model supports — multi-gear models give end users more flexibility.
Camping shower pumps turn any water container into an outdoor shower. The key specifications to compare are flow rate, battery life, charging time and waterproof rating. Flow rates in our CampFlow range span roughly 3.5 L/min to 10 L/min (pumping flow), battery life runs from 20 minutes to 2 hours, and waterproof ratings reach IPX7 on models designed for full immersion.
Adjustable models add flexibility: TOPFENG2619 offers 6-gear water pressure adjustment and 3 shower modes, while TOPFENG2620 provides dual-speed pumping with separate shower flow rates. For weight-sensitive applications, note that main units range from about 280 g to 620 g including accessories.
