    Does the type of pump affect extraction and taste, which pump is better?

    If I want a high quality espresso machine for under $100, is my only option to build it myself?
    I make espresso using a small old cheap vibrating pump machine that doesn't generate quite as much pressure as I'd like, so, I can't pack the coffee very firmly, or else it restricts the flow too much.
    I'd also like to be able to get a bit more crema without having to add more non-Arabica beans to my blend.

    Can you explain the “true preinfusion” through line pressure on a rotary pump? How come I can’t get true preinfusion with a vibration pump? Does this make a big difference on the espresso? I was thinking about getting a machine w/ a vibration pump and flow control, so I can alter the preinfusion, but I’m confused about if I can actually do it or not now. Thanks

      have you got your answer?

      If you hadn’t bought your machine already there’s the Lelit Elizabeth, a dual boiler machine that offers two preinfusion types. You can simply adjust the time the pump works and stops before pushing the water at 9 bars. Or you can use the second preinfusion, working with the pressure of the steam boiler, adjustable by the temperature of the water and the time chosen. Very clever. The machine is compact, really silent, has excellent temperature stability with two PID, and is easy to clean.

    Great explanation Charles, but can't you use an external pump and water bottle to supply water to a plumbable machine?

      Thanks! You absolutely can. In fact, we have a video that details how to set that up. I chose not to include it in this video because for most people it's more a matter of "do I want to drill a hole in my counter" than finding a water line. So, for most, it won't change the equation. Still an excellent option, particularly for coffee carts and the like!

      ​@@kevinking1391 While a rotary pump is capable of pulling water from an external reservoir or jug, we don't recommend it. The rotary pumps used are designed with water line pressure in mind so using a source with too little or too much pressure will cause extra wear on the pump, making it more likely to fail. By using a flojet you can replicate water line pressure and massively extend the life of your pump, so we always recommend using one.
      Given what you said, the Classika PID was going to be my immediate recommendation. If you're a staight espresso / americano person they're perfect - not to mention beautiful.
      Thanks for the support!

      ​@@kevinking1391 While we love the Virtuoso for drip coffee and pour over, it just isn't quite strong or precise enough for espresso. There are some really excellent entry-level espresso grinder options that didn't exist even a few years ago. The Eureka Mignon series offer stellar build quality and power. Having a dedicated grinder like that will really make your home espresso setup feel whole.

    Hi,
    thank you for your tips!!
    A serious question:
    In terms of espresso extraction and espresso quality ( sweetness, taste, etc…)
    Thanks,

      Can you please compare vibratory and rotatory pumps In terms of quality of espresso extraction, espresso flavors, and producing a consistent pressure?
      Tnx

    Does running a rotary pump machine only from its water tank reduce the longevity of the rotary pump? Keep getting conflicting information in regards to this on coffee forms? Assuming that I don’t let the water tank run dry? Thanks in advance!

    • @clivecoffee
      @clivecoffee  5 лет назад +1

      If you're using an internal reservoir there won't be any significant amount of additional wear. When using an external reservoir the additional wear to the pump occurs when the pump has to exert more force to move the water. Typically, external reservoirs are placed below a machine meaning that the pump needs to exert extra effort to raise the water and pressurize it. Hopefully, that answers your question.

    Hey Clive I have a very pertinent and desperate question about this, I hope you can give me an answer in the next few days. I was running through a few comparative videos between the Profitec 600, 700 and the ECM Synchronika and after watching a few I was prompted to a related video: (ruclips.net/video/o2W5SnXR3-s/видео.html) and I can see some issues wrong with this study/test like having the vibration pump machine 3-4yrs older than the rotary, and well using rocket machines over something more reliable, but the underlining results concern me. Can you give me some clarity on if a rotary pump gives a better texture and flavor to the pulled shot compared to the vibration pump? Also is shot really that unsteady and volitive with a vibration pump like shown in the video?
