How to Adjust a 2-Stage Pump

by Bryan Roberts

Two-stage hydraulic pumps are used in hydraulic systems, and allow for the passage of a substance through the pump and to other devices installed in the system. You can adjust the various working aspects of the pump, including pressure settings and accuracy of the valve, by making minor adjustments with common household tools.

1

Adjust the hydraulic gauge by locating the adjustment screw on the back of the gauge. Use a flathead screwdriver to turn the screw. Turning the screw allows you to adjust the screw needle, turning it to zero when needed.

2

Adjust the pressure switch, located behind the hydraulic gauge, by using a wrench to loosen the lock-nut on the switch, then turning the adjusting screw. This switch can be adjusted to stop the pump when it reaches a given pressure setting. Turning the screw counterclockwise will decrease the pressure switch setting.

3

Adjust the pressure regulating valve, located next to the pressure switch, by using a wrench to loosen the lock-nut on the switch, then turning the adjusting screw clockwise to increase the pressure setting. The switch should be adjusted to ensure a pressure differential of about 300 psi.
