Request a QuoteSix Waterjettingsale configurations present flow, working pressure, power source, mounting, indicative price and included hardware for shortlisting the right machine for each duty cycle. Complete-system sizing connects verified PSI and GPM with supply flow, nozzle capacity, hose loss, surface-cleaner width and runtime. Site safety and soil type determine gas, electric, hot-water or fixed-format selection.

Whole-System Sizing Around The Rated Point
Product ListFlow reference
4 GPM is approximately 15.1 L/min. A 15 L/min listing is a nominal class reference rather than proof that every selected model is exactly 4.0 GPM.
Rated working point
PSI and GPM belong at one operating point; separate maximum values may not be continuously available at the same time.
Water supply
Sustainable inlet flow, pressure, temperature, filtration and hose diameter are measured under load. A static-pressure reading alone does not establish supply capacity.
Nozzle and accessory capacity
Total nozzle capacity corresponds to pump flow and target pressure. Multi-nozzle surface cleaners divide that capacity across their installed nozzles and remain subject to the cleaner rating.
Pressure-side hardware
The hose, gun, fittings, unloader and accessories require ratings above the selected working point; the lowest-rated component limits the system.
Runtime and bypass
Continuous trigger-on time, pauses, route length and maintenance access determine duty needs. Pump duty cycle and permitted bypass time affect the choice of direct, belt or coupled drive.
Site-Driven Power, Temperature And Mounting Choices
Product ListGasoline Or Diesel
Mobile outdoor routes without grid power favor engine-driven equipment. Safe deployment remains outdoors away from doors, windows and air intakes, with fuel, oil, noise and engine maintenance in the operating plan.
Eléctrico
Fixed stations and sites that avoid local exhaust can favor electric power. Voltage, phase, full-load current, frequency, grounding, protective devices and cable limits remain site-specific order inputs.
Cold Or Hot Water
Cold water covers general soil removal when chemistry and dwell time are adequate. Greasy or oily contamination can justify hot water together with its burner, fuel and temperature-control complexity.
Portable, Wall Or Skid Mount
Portable frames support route work, while wall and skid systems improve controlled hose routing and repeatability. Drainage, ventilation, service clearance, vibration isolation and inlet plumbing shape the installation.

Price, Quantity And Delivery In One Package
These planning ranges are configuration-dependent; the signed quotation controls price, stock, production and shipping terms.
MOQ 1 configured unit. Indicative price is quoted per configuration; machine samples are charged at 100%, freight is separate, and a standard trial unit typically needs 7–10 working days.
For 2–5 units, tiered unit pricing follows the recorded voltage, engine, pump, hose and accessory package. Typical production is 15–25 working days with pre-shipment functional inspection and export packing.
For 6 or more units, request project pricing and reserve capacity against an approved specification. Typical replenishment is 30–45 working days after deposit and drawing or configuration approval.
Standard configurations are made to order; the signed quotation controls stock status and lead time. Custom electrical, engine, pump or frame work can extend the schedule.
Supply is available to major markets in the Americas, Europe, the Middle East, Africa and Asia under EXW, FOB or CIF quotation. Carrier, duties, destination compliance and installation are defined per order.
The shipment can include commercial invoice, packing list, operation manual and pre-shipment inspection record. Model-specific certificates are supplied only when listed for the ordered configuration.
Send The Configuration Inputs Engineering Needs.
Upload a site layout, hydraulic or electrical requirement, reference drawing, or accessory list so engineering can verify flow, pressure, power, mounting and interfaces before quotation.
4 GPM Pressure Washer Ordering Questions
These answers resolve the rated point, site supply and quotation scope before purchase.
Why can a 4 GPM pressure washer be listed as 15 L/min?
Four US gallons per minute converts to about 15.1 L/min, so a published 15 L/min rating is commonly treated as the nominal 4 GPM class. The ordered model’s quotation records its tolerance and rated working point.
Can I assume 4000 PSI and 4 GPM are available at the same time?
No. Pressure and flow must be stated at the same operating point. The pump curve or tested rated point and the quotation identify the nozzle, engine or motor, unloader and every high-pressure component for that combination.
How much water supply does a 4 GPM machine need?
The source must sustain at least the equipment manual’s inlet-flow requirement under load, not only show adequate static pressure. A correctly sized buffer tank or booster is appropriate only when the selected pump and installation instructions allow it.
What information is required for a firm quotation?
A firm quotation requires the selected model, target pressure and flow, surface and soil, daily runtime, voltage and phase or fuel choice, inlet-water conditions, hose and accessory requirements, quantity, destination and requested Incoterm.
Can Waterjettingsale review a custom pressure washer configuration?
Yes. The configuration form accepts a PDF, DWG, DXF, STEP, STP, JPG, JPEG or PNG reference up to 10 MB with quantity and work email. Engineering feasibility, interfaces, materials, price and production timing are defined before order acceptance.
