What to do if my Johnson Controls Frick RXF 101 pump does not pump?
- A
  Alexis JohnsonAug 15, 2025
  If your Johnson Controls Air Compressor pump isn't pumping, several issues could be the cause. It might have lost its prime due to an air leak or low level in the tank, so fix any air leaks and ensure the liquid level is adequate. Check that the pump is rotating in the correct direction and that the motor is operating at the correct speed. Also, make sure both the suction and discharge valves are open and that the strainer isn't clogged. If the relief valve is set too low or stuck open, adjust it. A worn-out pump will also fail to pump, so consider replacing it. Review any recent changes to the liquid system or operations that might explain the issue, and adjust the end clearance and head position if they are incorrect.

Why is my Johnson Controls Air Compressor pump not up to capacity?
- B
  benjaminhullAug 18, 2025
  If your Johnson Controls Air Compressor pump isn't reaching its full capacity, it could be due to several reasons. The pump might be starving or cavitating, so adjust the suction pipe size or reduce its length. A partially clogged strainer can also restrict flow, so clean it. Check for and fix any air leaks in the suction piping or along the pump shaft. Ensure the motor is running at the correct speed and is wired correctly. If the relief valve is set too low or stuck open, adjust or replace it. A worn-out pump will also reduce capacity, so replace it if necessary. Finally, make sure the end clearance and head position are correct.

Why is my Johnson Controls Air Compressor pump so noisy?
- O
  Omar OwensAug 22, 2025
  A noisy Johnson Controls Air Compressor pump can stem from several causes. The pump might be starved, meaning heavy liquid can't reach it quickly enough, so increase the suction pipe size or reduce its length. Alternatively, the pump could be cavitating due to liquid vaporizing in the suction line; in this case, increase the suction pipe size or raise the liquid level if the pump is above it. Ensure proper alignment and check for a bent shaft or rotor tooth, straightening or replacing if necessary. Also, inspect for and clear any foreign objects that might be entering the pump through the suction port.

What to do if Johnson Controls Frick RXF 101 pump starts, then loses its prime?
- C
  Christopher HernandezAug 25, 2025
  If your Johnson Controls Air Compressor pump starts but then loses its prime, consider these potential causes. A low level in the tank could be the issue, so maintain a higher level. Liquid vaporizing in the suction line can also cause this problem, so prevent liquid vaporization. Check for air leaks or air pockets in the suction line, including leaks through packing or the mechanical seal, and inspect and repair any leaks. Finally, worn components can lead to loss of prime, so replace them as needed.

Why does my Johnson Controls Frick RXF 101 Air Compressor pump take too much power?
- A
  Angela MeyerAug 27, 2025
  If your Johnson Controls Air Compressor pump is consuming excessive power, several factors could be responsible. Check that the motor speed, reducer ratio, and sheave size are correct for your setup. If the liquid is more viscous than the unit is designed to handle, consider heating the liquid, increasing the pipe size, slowing the pump down, or using a larger motor. Confirm the discharge pressure and modify the system accordingly if it's higher than calculated. Ensure the pump is properly realigned. Also, verify that the clearance on the pumping elements is sufficient for the operating conditions, checking for drag or contact and increasing clearance where necessary.

What causes a high pressure reading on the discharge port of a Johnson Controls Frick RXF 101 Air Compressor?
- K
  kevinrodriguezAug 31, 2025
  A high-pressure reading on the discharge port of your Johnson Controls Air Compressor could be due to several reasons. High viscosity combined with a small or long discharge line can cause this, so reduce viscosity or optimize the discharge line size. Make sure the gate valve is fully open. A plugged filter can also increase pressure, so clean or replace it. If the vertical head didn't account for a high specific gravity liquid, adjust the system design accordingly. Inspect and clean the inside of the pipe if it's partially plugged from buildup. Ensure the liquid in the pipe is at the correct temperature, and if it has solidified due to a chemical reaction, replace it. Lastly, check that the relief valve isn't set too high and adjust it if necessary.

What causes a low vacuum gauge reading on the suction port of a Johnson Controls Frick RXF 101?
- R
  Richard JonesSep 2, 2025
  A low vacuum gauge reading on the suction port of your Johnson Controls Air Compressor can be caused by a few things. There might be an air leak in the suction line, so inspect for and fix any leaks. Ensure the end of the pipe is submerged in liquid. If the pump is worn, replace the worn components. Also, the pump might be dry and need priming, so prime the pump.

Why is there a high reading on the vacuum gauge of my Johnson Controls Air Compressor suction port?
- K
  Kristen BooneSep 5, 2025
  A high reading on the vacuum gauge of your Johnson Controls Air Compressor suction port can indicate several issues. The suction line might be blocked due to a stuck foot valve, closed gate valve, or plugged strainer, so check the suction line for blockages. If the liquid is too viscous to flow through the piping, reduce its viscosity. The lift might be too high, so adjust the lift height. Additionally, the line might be too small, so increase its size.

What causes a low pressure reading on the discharge port of a Johnson Controls Frick RXF 101 Air Compressor?
- D
  Darlene MartinSep 8, 2025
  A low pressure reading on the discharge port of your Johnson Controls Air Compressor can be attributed to several factors. The relief valve might be set too low, so adjust the relief valve setting. If the relief valve poppet isn't seating properly, repair or replace it. Too much extra clearance can also cause low pressure, so reduce the extra clearance. Lastly, if the pump is worn, replace the worn components.

What to do if vacuum gauge reading is erratic on Johnson Controls Frick RXF 101?
- T
  Troy GravesSep 12, 2025
  If you observe a fluttering, jumping, or erratic reading on the vacuum gauge of your Johnson Controls Air Compressor, it could be due to liquid vaporizing. Identify and alleviate the conditions causing liquid vaporization. It may also be caused by liquid coming to the pump in slugs, possibly due to an air leak or insufficient liquid above the end of the suction pipe, so address air leaks and maintain an adequate liquid level. Vibrations from cavitation, misalignment, or damaged parts can also cause erratic readings, so check for cavitation and align or repair any damaged parts.
