Can the lower pressure (40 PSI) be increased? Meaning can you make the pump start building pressure again at, lets say 50PSI? I'm asking because i need a working pressure range of 50PSI to 90PSI
Answer This Question
The factory set pressure of this pump is 70 PSI. It is expected that when the pressure drops to about 50 PSI, the pressure switch will be powered on and the pump will start working. If you want 50-90 PSI, you need to rotate the pressure adjustment screw of the pressure switch clockwise and use a pressure gauge to measure the pressure. It is estimated that it can be adjusted to 85 PSI.

Kan man pumpa motorolja med den? Eller klarar inte packningarna det? Ny motorolja alltså.
Answer This Question
Det finns en gummiventil inuti maskinen som inte är motståndskraftig mot motorolja, så det rekommenderas inte att pumpa motorolja.
