What is a Multi-Stage Cleaning System?

A Multi-Stage Cleaning System is a series of motor-pump packages connected to the same set of controls and responds to the demand for  high pressure water by automatically "staging in" or starting only the number of pumps needed to meet this demand.  Conversely, as the demand for water falls, the pumps "stage out" or turn off.

By locating the unit in a convenient location and plumbing it to the cleaning areas, the operator need only connect the high pressure hose / gun assembly at a cleaning station and squeeze the  trigger to operate the machine, thus protecting the equipment from potential misuse.

How does it Work?

The high pressure water (usually between 1000 and 3000 PSI) leaves the pumping unit and travels through a network of high pressure piping to the area where cleaning is required.  the termination points of the pipe are vertical drops approximately five feet from the ground and usually consist of a PSC CS-1 Cleaning Station with a quick disconnect.  The CS-1 allows for the introduction of cleaning chemicals into the high pressure water stream where it is then discharged through a high pressure hose assembly with a trigger gun / wand, without effecting the overall system pressure.  The system is controlled by an automatic stop/start circuit (trigger gun activated) consisting of a flow switch wired to the pump motor control.  Once the trigger gun is activated, the flow switch senses a demand for water and signals the control to start the pump motor; with hot water systems the heater is now automatically engaged.  Depending on how much piping is use in the distribution system the entire process, whether one or more trigger guns are activated, usually takes place in less than a second.  A timer automatically shuts off the centralized pressure washer after 10 to 15 seconds if no high pressure water is called for preventing excessive stops/starts with multiple gun systems.
