Compare pressure labels and water flow together with the pump, engine, frame and supplied hose/nozzles. Retain catalogue pressure and flow pairs as pairs until their working/peak definitions for the quoted version are established.

Use the frame comparison for a real handling question

Ask the sample reviewer about transport, storage, hose management and service access for the buyer’s stated job. A hose reel or a different frame can matter to the range even where two pressure entries are similar. Show those structural differences without assigning an untested cleaning-rate benefit.

The IEC 60335-2-79: 2021 scope page includes high-pressure cleaners with several drive systems, including internal-combustion engines. That scope information is background for a technical requirements review, not evidence that a DUPOW model has passed the standard. Use the inspection file and parts schedule to carry the selected version through shipment and later service.

Describe the cleaning jobs first

Separate vehicle, property-maintenance, agricultural and heavier outdoor-cleaning needs. Record the expected mobility, water source, working time, storage conditions and operator profile. This creates a practical basis for comparing models instead of selecting the largest pressure number.

Compare working pressure and water flow together

Working pressure and maximum pressure are not interchangeable. The RFQ should state which figure is being compared and pair it with water flow. Buyers should also confirm how the figures are measured, the pump configuration and the exact engine version. Marketing language should follow the approved written specification.

Buyer checkpointAsk every quotation to separate working pressure, maximum pressure, water flow, engine reference and included hose or nozzle configuration.

Choose a frame around transport and storage

A-frame, X-frame and cart formats create different handling, hose-storage and carton implications. Review wheel size, handle layout, hose reel where offered, stability, service access and the dimensions that matter for retail, warehouse and container planning. The best format depends on the channel rather than appearance alone.

Confirm pump, hose and accessory scope

Record pump type, inlet arrangement, high-pressure hose length, spray-gun and lance configuration, nozzle set, detergent provision and any quick-connect requirements. Confirm whether accessories are standard, optional or market-specific. Replacement seals, hoses, nozzles and other service parts should be identified before the first order.

Representative DUPOW families

These real product families show three frame and handling positions. The listed figures come from the current reviewed family pages; final order specifications and market requirements remain subject to confirmation.

Plan inspection around the approved sample

Inspection checkpoints should connect the approved sample, written specification, labels, accessories and packaging. Typical order-specific checks may cover recorded engine and pump references, basic function, visible leakage, controls, hose and nozzle contents, fasteners, labels, carton condition and agreed packing quantities. The final inspection plan must match the exact product and order.

Buyer FAQs

Is the highest catalogue pressure the continuous working pressure?

Do not assume that it is. Keep the original label and request the working/peak definition and rating conditions for the quoted version.

Are the PW-008 flow entries an 8–9 L/min range?

The current catalogue lists the pair 7.5/9 L/min. Retain those entries and their configuration definitions rather than substituting a different range.

What makes two frame styles commercially different?

Review transport, storage, hose handling, service access and packing for the actual sample. The difference should be explained in the buyer’s application brief.
