How to choose your mini-pump ?

For those who don't know, Zéfal'due south core business is inflation and therefore pumps. After inventing the Presta Valve in 1880, Zéfal became a specialist in pumps.

As applied science advances and mid-cycle evolution, the types of pumps have become multiple, and the pumps have get smaller and smaller. Mini-pumps have appeared and they are the ones that salve us later on a puncture in the heart of nature. We prefer to utilize it every bit footling as possible, only when it does, we want information technology to piece of work as well as possible to avoid wasting time for groups of friends, catching cold or having too much pain in the stomach. arms. To do this, y'all accept to choose the model that best suits your practise and your needs!

Road and MTB, non the same constraints depending on the practice:

The characteristics to ensure an inflation in adequacy with the practice (Route or MTB) are the Ø (diameter) and the length of the pump tube.

Let's commencement from the post-obit premise: The larger the diameter and length of the tube, the greater the volume of air delivered...

So far, it seems logical.Simply where does the practice come in (Route or MTB)?

The practice intervenes at the level of the pressure to be reached in your tire which will result in an effort to exist made on the handle of the pump when engaging the air in the tire. This strength is linked to the diameter of the aggrandizement tube.

1 / At Low pressure and large book (MTB) all pumps are suitable, small-scale and large diameters, short or long.

On the other hand, it is preferable and more efficient to take a big diameter and a long length.

If you choose a pocket-size diameter and short pump for the ATV, inflation will be possible only the number of strokes and the fourth dimension spent will be very high.

ii / At high force per unit area (Route) not all pumps are suitable.

To ensure high pressure The pump must have a small-scale diameter, which reduces the effort when inflating.

If you lot associate this minor bore with a large length, the inflation effort will not alter, but the pump volition be more efficient. On the other hand, if you take a big diameter pump, regardless of its length, you lot will be limited and you will not be able to exceed a pressure of 4 to 5 bar which will not exist sufficient for a road tire.

In summary, a mini-pump for the mountain cycle requires a big diameter of tube, while the one for the route requires a small one.

Pump length

The length of the tube does non change the orientation of the pump, road or ATV, but improves the efficiency of the product. The longer the tube, the more efficient the pump, and the faster you will be.

And what blazon of plumbing fixtures to choose?

When choosing your mini-pump, the type of connexion it volition take into account in your selection. There are 4 types, here they are:

• Direct without lever:

The special feature of this connectedness is that the user, in improver to the inflation endeavour, must constantly keep the pump nozzle on the valve to seal.

This blazon of inflation requires experience.

•  Directly with lever:

Valve connection like to the previous one, but with a compression lever for sealing. The connection is fabricated in two stages, placing it on the valve and then operating the lever to compress the valve seal. Inflation is easier, but has the risk of bending the valve. This phenomenon occurs when the passenger is leaning on the valve and not on the rim when the air is introduced into the tire.

• Direct to flexible hose with lever:

This connexion works in the same principle as the straight lever connection simply has the big advantage of not having a rigid connection between the connexion and the pump body. Indeed, this connection is fabricated by means of a flexible pipage. The risk of damaging the valve does not exist

On the other hand, equally this support does not exist a counter force to recoup for the force of introducing air into the tire is mandatory. This counter-effort is disagreeable at high pressure.

•  Screw-on flexible hose

The peculiarity of the latter is that the sealing on the valve is done by screwing.

The seal is very proficient and different other fittings the head does not have the hazard of detaching from the valve. As the connection betwixt the pump body and the screw connexion is made past a hose, nosotros observe the disadvantage of the counter force to be provided to compensate for the force of introducing air into the tire.

Our sm all option:

• Practicing the road and looking for a mini-pump with a flexible hose screw connection: Air Profil FC03

• Mount biking and looking for a mini-pump with a straight lever connexion: Z-Cross XL

• Mountain biking and looking for a mini-pump with a flexible hose screw connection: Air Profil FC01

• For universal use: Air Profil XL

At that place are other options for quickly inflating your tire after a puncture. Our EZ Max FC mini-pump has the particularity of combining 2 functions in one production, the mini-pump and the CO2 inflator. You lot tin can therefore use a CO2 cartridge with it, in add-on to the classic use as a mini-pump. CO2 cartridges with their inflators or Repair Spray are other solutions to consider.

You at present have all the information you need to cull the mini-pump that will adjust you! We even so hope that you lot volition employ it as little every bit possible.
