Balancing your pump to the size and quantity of your nozzles is crucial to the performance and life of your system.  When balanced properly with the right size pump and nozzles, not only will your pump last longer,  but it will operate quieter and cooler.  For this reason, we offer 5 pump sizes to get the proper balance.  No matter who you purchase from, be sure the pump's capacity matches the nozzle size/quantity.  

Unlike low and mid pressure systems which use a diaphragm pump, high pressure pumps usually use 3 pistons to pump the water up to 1000 psi or greater. Whereas varying the nozzle size and quantity on a diaphragm pump has little negative effect on the pump itself, this is not true of high pressure piston pumps. High pressure piston pumps are designed to pump a certain volume of water at a certain pressure.  For a given pump and nozzle size, using too few nozzles will overwork the pump causing it to run hot, operate louder than normal, and cause pre-mature wear and tear. Using too many nozzles will exceed the pump's capacity and result in lower nozzle pressure and reduced performance.

When you purchase a system from us, we supply a pump which is made for your nozzle size and quantity chosen.  For example: lets say you chose a 30 nozzle kit with ,006" nozzles. Referring to the nozzle chart, this would mean that a SM-150 pump would be the best choice. Many customers will want to add, subtract, or change their nozzle size not understanding the principles outlined in the last paragraph. When considering modifying your system, follow these guidelines:

1. Consult the nozzle chart first. Note the minimum and maximum nozzle size and quantity for your pump.

2. Stay at the mid to upper range of the nozzle size and quantity whenever possible to lower pump noise and prolong pump life

3. If you need to add more nozzles or increase the nozzle size which takes you beyond the capacity of your existing pump, contact us about upgrading your pump.

Keep your pump happy and it will keep you happy for years to come.
