The math says 3hp should get you 4.38gpm @ 1000psi or 3.65gpm @ 1200psi. With 5hp its 7.3gpm @ 1000psi or 6.08gpm @ 1200psi. With my 2506 nozzles at 1200psi I should be using ~3.29gpm and ~2.7hp. So mathematically 3hp would work. The 516 pump is rated from 4-5 gpm depending on the pump rpm. My pumps are spinning at 950rpm (4gpm) and with my 5hp I should be able to pump up to ~1825psi with my 2506 nozzles to max out my set up.

Depending on the application 5,3, or 2HP would work.

Will show Model 516 as example;
* produces 3 GPM @ 713 RPM, 2HP when pressure is set to 1000 psi.
* produces 3 GPM @ 713 RPM, 3HP when pressure is set to 1500 psi.
* produces 4 GPM @ 950 RPM, 3HP when pressure is set to 1100 psi.
* produces 4.5GPM @ 1070 RPM, 3HP when pressure is set to 1000 psi.
* produces 5 GPM @ 1200 RPM, 3HP when pressure is set to 900 psi.
* produces 4 GPM @ 950 RPM, 5HP when pressure is set to 1850 psi.
* produces 4.5GPM @ 1070 RPM, 5HP when pressure is set to 1650 psi.
* produces 5 GPM @ 1200 RPM, 5HP when pressure is set to 1500 psi.

Re; pressure & nozzle size;
Pressure is created by restriction of the pumped water flow through the spray nozzle(s).
No nozzle(s) or oversized nozzle(s) = Reduced or no pressure.
Pressure is controlled by a pressure regulator (or unloader).
Water delivered from the pump, which is not needed to meet a set pressure, is bypassed through the pressure regulator (or unloader).

Note water flow & size nozzle(s).
Water flow through a nozzle with vary with pressure, refer to Nozzle Performance Chart.
examples;
#5 nozzle passes 2.5 GPM when pressure is set to 1000 PSI.
#5 nozzle passes 5 GPM when pressure is set to 4000 PSI.
#6 nozzle passes 3 GPM when pressure is set to 1000 PSI.
#6 nozzle passes 6 GPM when pressure is set to 4000 PSI.

Insure correct Motor RPM and pulleys.
Electric Motor RPM, Electric motor pulley diameter, & Pump pulley diameter determine Pump RPM.
Pump RPM determines its flow produced.

I like my 1508 tips. When you hold the gun the 15 degree feel more powerful than a 25 degree and 15 has more cleaning power at the point of impact.

This morning while I was mucking out bays waiting for the police to show for another vandelism call I was thinking about trying a 2505 nozzle then I thought why should I, I've only been using the 1505 nozzles for 30 years plus so why change now. Then the police showed up so I lost that thought.
