Many customer will ask how much pressure and flow sprayer pump motor should I choose? It depends on your actually working application requirement.Today we share some use of the pressure switch and bypass system.

Let us select 100PSI 5LPm FLo3203 model speaking, if you adjust the eccentric gear in clockwise direction, the pressure switch in lab testing will increase, but the suitable range is not large than 10 PSI. If you add more than it, pump will leakage. So if you turn into Anti-clockwise direction, pump pressure switch will down. But recommend no less than 10 PSi or pump will cause working problem.

How about bypass play role during working?

12v battery sprayer pump equipped with an external bypass system are designed to pump at high pressure while at low or high flow rates. Models equipped with bypass only must be turned off/ on manually, or by an independent control device. Bypass system can protect pump from working continuously damage. If you forget Dc sprayer pump turn off pump and bypass will play important role in it. It can let pump in idle speed avoiding motor burn out. Pumps equipped with a bypass recommend for continue to run till the power is manually turned off.

The most important point, if you want to adjust the pressure of  the sprayer pumps, pls tell us sales and we will let professional engineer adjust everything well and sure not any problem.
