Square D / Pumptrol · Class 9013 Type FHG
9013FHG42J55
The 150 psi build of the FHG family, used on two-stage residential and light-commercial recips with a 175 psi MAWP tank. The wider 40 psi differential cuts starts per hour roughly in half compared to the 95/125 switch on the same tank.

Size against motor full-load amps with the motor amperage calculator, and check feeder sizing with the voltage drop calculator.
Adjustment
- Range nut only. Confirm the tank MAWP is at least 175 psi before setting cut-out to 150.
- Check the ASME relief valve rating: it must pop at or below MAWP and above your cut-out with margin.
Before you open the cover
Kill power at the disconnect and lock out. Bleed the tank to 0 psi. Never set cut-out above the tank data-plate MAWP. Verify your numbers first in the cut-in / cut-out calculator.
Best fit
- Two-stage 5–7.5 HP single-phase recips
- Shops running 150 psi header pressure
Watch out
- Higher cut-out means higher discharge temperature — check the head and valve plate if the unit runs hot.
- A tired check valve at 150 psi back-bleeds harder and shows up as rapid restart after shutdown.
