Why Argal ASTRA Evo DDE does not run?
- B
  Barry JohnsonAug 15, 2025
  If the Argal Water Pump does not run, it could be due to a circuit without air. Check the circuit, including valves, connections, and pressure regulators. The issue might also stem from insufficient air pressure, in which case you should increase the air pressure. Another possibility is an insufficient air flow rate; ensure that the pipes and fittings have suitable passages.

What to do if Argal ASTRA Evo DDE works but does not pump?
- S
  smithjorgeAug 19, 2025
  If your Argal Water Pump is running but not pumping, several factors could be at play. The valve balls may not be closing properly, or the valve seats might be worn. Disassemble the manifolds and clean the seats, or replace the balls and seats if they are worn. Also, check for a loose suction connection and tighten the suction line if needed. A blocked suction line could also be the culprit, so be sure to clean it. Other potential causes include a blocked silencer (check, clean, or replace it), starting the pump with high pressure (start the pump slowly), air in the suction or discharge line (vent the lines), excessive suction height (reduce the height), or fluid that is too viscous (install larger pipes and decrease pump cycles).

How to improve suction of Argal ASTRA Evo DDE Water Pump?
- S
  Sarah WoodsAug 22, 2025
  If your Argal Water Pump has insufficient suction, start by checking and re-tightening the suction connections to ensure they are secure. A clogged suction pipe could also be the cause; inspect, clean, or replace it as necessary. Additionally, a blocked silencer can restrict suction, so check, clean, or replace the silencer. Finally, inspect the valve balls and seats; if the valve balls do not close or the valve seats are worn, disassemble the manifolds and clean the seats, or replace the balls and seats if they are worn.

Why does my Argal ASTRA Evo DDE stall?
- C
  caindeborahAug 28, 2025
  If your Argal Water Pump stalls, the suction pipe may be clogging during operation; if so, replace the suction pipe. Dirty air full of condensate or oil can also cause stalling; check the air line. Ensure sufficient air volume and pressure by checking the pressure with a gauge while the pump is running, and inspect all air connections. A defective pneumatic exchanger should be replaced. Also, make sure the stop procedure was correctly followed; if not, respect the stop procedure.

Why Argal ASTRA Evo DDE Water Pump works irregularly?
- S
  Sabrina MurrayAug 30, 2025
  If your Argal Water Pump works irregularly, the internal pneumatic exchanger may be clogged or defective, requiring replacement. The diaphragms might be broken and need replacement. If the valve balls do not close or the valve seats are worn, disassemble the manifolds and clean the seats, or replace the balls and seats if they are worn. Defective air valves should be cleaned or replaced. A worn shaft also requires replacement of the pneumatic exchanger. Ice on the discharge can cause issues, so dehumidify and filter the air. Finally, ensure sufficient air volume or pressure by checking the pressure with a gauge while the pump is running and inspecting all air connections, ensuring sufficient flow rate in the air control devices.

How to fix liquid leaks from Argal Water Pump?
- M
  Michelle MendezSep 2, 2025
  If liquid is leaking from your Argal Water Pump, start by checking the tightening torques of the screws on the fluid chamber to ensure they are properly tightened. If the O-rings on the manifolds are damaged, replace them. Also, inspect the diaphragms for damage and replace them if necessary.

What causes diaphragms breakdown in Argal ASTRA Evo DDE Water Pump?
- D
  Darrell StephensSep 5, 2025
  Diaphragm breakdowns in the Argal Water Pump can occur due to several reasons. If the pressure is too high during installation, use a protective treatment system or air regulation. If the pump runs dry for extended periods, run it slowly when not filled with fluid. Ensure a pressure balance between the air and fluid sides of the diaphragm to prevent breakdowns caused by excessive suction-side pressure.

Why Argal ASTRA Evo DDE works with slow cycles?
- E
  Eric ScottSep 9, 2025
  If the Argal Water Pump cycles slowly, it could be due to excessively viscous fluid, for which there is no remedy mentioned. Alternatively, the discharge or suction pipe may be clogged; check and clean them.

Why Argal Water Pump does not deliver indicated flow rate?
- V
  vaughnjeffreyNov 24, 2025
  If your Argal Water Pump isn't delivering the expected flow rate, begin by checking and cleaning the air supply and suction connections, as they may be blocked. Ensure the product suction pipe is correctly connected and appropriately sized. Inspect and clean any clogged pipes. If the fluid is too viscous, install larger pipes, especially for suction, and decrease the pump cycles. Check the valve balls and seats; if they do not close or are worn, disassemble the manifolds and clean or replace them. Verify sufficient air volume by checking the pressure with a gauge while the pump is running; if low, inspect all air connections and ensure sufficient flow rate in air control devices. Check and replace the diaphragms if needed. Other causes may be icing on the silencer (improve air quality), pr...
