Birelart screw pump tank attachment

Summary: "Screwed" mounting

The tank is screwed into the body of the pump. Between these two rooms is an O-ring (O-Ring) or a sealing washer that does all the work.

• The role of fixing: Hold the tank integral with the pump while ensuring perfect sealing to prevent air from being sucked into the circuit during the pumping phase.

• Fragility: The tank threaded tip is often plastic. If you force too much, you risk breaking plastic in the body of the pump (very difficult to extract).

- Mounting Tuto: Golden Rules

1. Verification of the seal: Before screwing, always check that the O-ring at the base of the thread is present, flexible and uncrowded. This is the seal that seals, not the net of the screw !

2. Net cleaning: Make sure the female thread in the pump body is clean. A grain of sand in the net can make you believe that the tank is stopped while it is poorly screwed.

3. Hand tightening: Screw by hand until the gasket is in contact with the surface of the pump body. Once in touch, give a lightweight tightening (maximum 1/8 turn). It's enough.

4. Orientation: If your tank must be oriented in a certain way so that the plug is accessible, do not force to rotate it. Unscrew slightly, check the seal, and put it back.

💡 Michel's trick

"There is a mistake I see very often on paddocks and is catastrophic. The trick: Some drivers put teflon ribbon or joint dough on the net to ensure the sealing. Do never do that ! The brake fluid is aggressive, it will break down the teflon, and pieces will leave in your pump and block the valves. If it flees is that your seal is dead or the net is damaged. Replace the gasket, that's all. The braking is precision mechanics, not plumbing. "

❓ FAQ SEO (Frequently Asked Questions)

Q: My tank moves a little, is it normal ?

A: If he pivots slightly but does not ooze, it is not necessarily serious on some models. However, if it has vertical game, the seal does not compress enough and you risk an air inlet. Replace the O-ring at the base.

Q: How to extract a broken tank tip into the pump ?

A: This is the worst situation. You must use a very small conical screw extractor. If you do not have it, try to heat up a flat screwdriver to push it into the plastic remained stuck, let cool, then unscrew gently.

Q: Why does the tank unscrew with vibrations ?

A: If your tank tends to unscrew, check if there is no abnormal vibrations on your pump holder. Normally, with a seal in good condition, the compression pressure prevents natural unscrewing.
