How to fix a malfunctioning air regulator on a Graco EcoQuip 2 EQm Water Pump?
If the Graco Water Pump air regulator is malfunctioning, first disengage the blast control switch. Then, adjust the pump inlet air pressure regulator until the pump air pressure regulator gauge reads 100 psi. Make sure the supply air pressure is at least 100 psi and check the air inlet filters. If the issue persists, replace the pump air pressure regulator.
What to do if the pop-up on my Graco EcoQuip 2 EQm cannot seal properly?
If your Graco Water Pump pop-up cannot seal, make sure the pop-up is clean and free of any debris, especially in the o-ring sealing area. Check that the pop-up is properly aligned when closed, ensuring there are no gaps between the o-ring and the pop-up. Also, remove the o-ring to make sure the o-ring gland is clear. If the pop-up or o-ring is worn, replace it.
What to do if the water pressure regulator is malfunctioning on my Graco EcoQuip 2 EQm Water Pump?
If the Graco Water Pump's water pressure regulator is malfunctioning, adjust the water pressure regulator until the pot pressure gauge reads 185 psi (12.75 bar, 1.275 MPa). If this adjustment is not possible, service the water pressure regulator. No answer.
How to disengage the emergency stop on a Graco Water Pump?
To disengage the emergency stop on your Graco Water Pump, simply disengage the emergency stop (L).
Why is my Graco Industrial Electrical pot unable to fill or pressurize with water?
If you're having trouble filling or pressurizing the Graco Industrial Electrical pot with water, first, disengage the emergency stop. Then, ensure your air compressor meets the minimum air flow requirements specified in the Technical Specifications (page 67) and that the air inlet pressure gauge reads between 100-175 psi. Also, make sure the water tank is full, the inlet ball valve is open, and the water inlet filter is clean. Check the pump air pressure regulator, and adjust it to 100 psi. Finally, ensure the pop-up is clean, properly aligned, and the o-ring sealing area is free of debris. If adjusting the water pressure regulator to 185 psi isn't possible, further service might be needed (see manual 309474).
What to do if the blast hose recoils heavily on a Graco Industrial Electrical?
If the blast hose recoils heavily when you engage the blast control switch on your Graco Industrial Electrical system, it could be because the abrasive ball valve was left open during shutdown. To prevent this, follow the shutdown procedure on page 21, step 2. Alternatively, the abrasive ball valve or the pinch hose might be worn. To check, pressurize the pot, close the abrasive ball valve, and engage the blast control switch. If the pump rod is still moving, replace the abrasive ball valve or the pinch hose. For pinch hose replacement, refer to page 32.
What to do if my Graco EcoQuip 2 EQm is unable to fill or pressurize?
If your Graco Water Pump pot won't fill or pressurize, first, ensure the emergency stop is disengaged. Then, check that your air compressor meets the system's minimum airflow requirements and that the air inlet pressure gauge reads 100-175 psi. Clean or replace air inlet filters if needed. For inadequate water supply, if you have a water tank, ensure it's full, the inlet ball valve is open, and the water inlet filter is clean. Tighten all fittings. If you have pressurized supply connections, ensure the connection is pressurized, meets pressure and flow needs, and all fittings are tight. Check the inlet water pressure regulator for proper installation and clean its screen filter. If the water pump air regulator is malfunctioning, disengage the blast control switch and adjust the pump inlet ...
