Which kind of peristaltic pump is useful in beer brweing?

[Tonnery]

Hi guys. Which kind of peristaltic pump is useful in beer brweing? The below one can work?

- Flow range:0.016-513.77ml/min
-Speed: 0.1 to 300 rpm, reversible
-Speed precision: 1 rpm (External Control 0.1 rpm)
-Display: Displays speed range and running status
-Time function, preset time,more convenient
-Time function:Time range is 0.1s-99 hr
-External interface: Start/stop and cw/ccw control, 0 to 5 V, 0 to 10 V, 4 to 20 mA and 0 to 10 KHz speed control
-Communication Interface: RS485
-Power supply: DC 24 V/1A or Adapter
-Power consumption: < 20W
-Operating condition: Temperature 0 - 40 °C
-Relative humidity < 80%
-Drive dimensions (L × W × H): 140 × 96 × 96(mm)
-Pump weight: 0.8kg
-IP rating: IP 31

Please give me some advices to improve it.
And how about the price 300~240$.

1/2 liter/min as a max flow is awfully slow. Also, @ that price you can buy two March or Chugger pumps!

40° C limit is a show stopper...

 

[timdillon36]

And only rated to 40°C?
And DC powered?

I doubt I would use it if it was given to me for free.

So. Dear sirs, I got the informations from your answers, I got it.
1st, the flow rate is important, the larger the better.
2nd, the cost is also very important.
3rd, the precision is not needed much more, and the 40°C is too low.

 

[Tonnery]

What about this type? No motor, only peristaltic pump HEAD
-20°C~120+°C, in boiling water is acceptable.
2.4L/min touched, 2.0L/min confirmed,
105$~110$.
JUST NO MOTOR. the motor in China is not suitable now.

Please give me some advices to improve it again sirs.

Is it rated as food grade?
Why the need for a peristaltic pump?
Again, for $125 or less you can get a March or Chugger pump. 120v or 220v.
SS head for a few bucks more. All you need to add are inflow connection to match your equipment & a ball valve to control flow. Also, max flow rate is 7.5 gal (28 L) per minute!

Hi dear sir,
Yes, it is food grade, the tube can be took into water 100°C as boiling.
Yeast inline to fermentors, isloating others, and the peristaltic pump can transfer beer\air\foam.
About $105~$110.
So kindly sir, I am a beer lover, and I just want to know what kinds of the peristaltic pump should work in brewing. And I like DIY very much, though in China. About this pump-head, we have no distributor in USA, so it could not be sold here now.
Brewing is cool and DIY is happy.

I'm not aware of a peristaltic pump that can/will transfer at a rate satisfactory for home brewing.
I've dealt with peristaltic pumps in medical applications for surgery & in clinical labs. None would provide a transfer rate approaching 25+ liters per minute (at least not at a reasonable cost)!
Also cleaning is another potential problem, as is the durability of the tubing which would need frequent changes. Particularly when you are planning to use it at such high temperatures.

The only application that requires 25 liters per min is whirlpooling. Other operations like recirculation or sparging need 2 liters per minute max using 8mm ID tubing minimum.

 

[Tonnery]

Thanks Bobby.
I have a bull that can touch the whirlpooling needed, but also peristaltic pump.
Show you.
Just Happy new year, for you, and sir govner. Happy 2017.

Flow range: 1.5-40 L/min
Mass transport, the highest flow 40L/min.
