Pump duty point
Impact needs pressure and flow together. A high pressure, low flow pump cleans a spot; a lower pressure, high flow manifold floods a whole load. Ask the pump model and its rated pressure at rated flow.
No DramaBuyer guide · Industrial cleaning
A spray cleaning machine cleans by impact, impact falls quickly with distance from the nozzle, and the figure that decides your result is the pressure and flow arriving at the part, which no listing states and every quote should.

01
Impact needs pressure and flow together. A high pressure, low flow pump cleans a spot; a lower pressure, high flow manifold floods a whole load. Ask the pump model and its rated pressure at rated flow.
Flat fan, full cone or rotating nozzles, how many, and the distance from nozzle to the nearest and farthest face of your part. A quote without a nozzle layout cannot be compared.
Faces hidden behind other faces stay dirty. Fixtures that present each face, a rotating basket or an oscillating manifold reduce shadowing; a loose heap does not.
Spray whips detergent into foam, and foam overflow starves the pump. Spray machines need low-foam chemistry and a vapour exhaust duct.
Cabinet for batches, conveyor for flow, drum for small loose parts. The same name covers produce washers and trolley washers too, so name your product first.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

| Require this | A pass looks like |
|---|---|
| Load a dummy part marked with removable paint or water-sensitive paper in the worst position of a full load. | Every face that must be clean shows spray impact; any shadowed face was agreed in writing before the run. |
| Fit a gauge at the manifold, not at the pump, and run at full flow with all nozzles fitted. | Manifold pressure sits inside the band stated in the contract. |
| Run your chemistry at working temperature for a full cycle. | No foam overflow, no pump cavitation noise, and mist stays inside with the door closed. |

An industrial ultrasonic cleaner. Spray reaches faces in its line of sight only.
A high pressure industrial washer with a lance, or dry ice blasting for moulds cleaned in place.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
07
Every machine we source in this area is on the Industrial cleaning page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
Put the same part in both, compare pump duty point, nozzle layout and manifold pressure, and look at the shadowed faces.
Manifold gauge reading at full flow, marked dummy part, foam check with your detergent, door interlock and vapour exhaust.
A Declaration of Conformity with serial number, the machinery and low voltage rules named, CE marking on the unit and a manual in your language.
Checking the Declaration and technical documentation exist, putting your name and address on the machine or papers, and keeping the documents available.
