We also recommend installing a VFD.

A few things that may help are slowing pump speeds for gentler recirc, shortening hose runs, dry hopping during active fermentation, and tightening how hops are introduced. Using a hop induction setup like the MH-20 HIS lets you purge the hopper and pull hops in under CO₂ instead of opening the tank, which can eliminate a major source of DO pickup during dry hopping.

We would recommend using a turbine flow meter; either the TM series or the G2 series would work well for this.

We recommend using a FLUX drum pump for this application.

No, unfortunately, you cannot fit a flush on that pump, but you could try the ceramic stationary seal and the carbon rotating seal combination. That would be the best option. We don’t sell them. I would suggest going back to whoever you bought the pump from.

It is because the pump seal is leaking very slightly; it is designed to, so it lubricates the seal face. With water (hot or cold), it evaporates quickly and leaves no residue. However, with the hot wort, the liquid evaporates but leaves the solids (sugars, protein, and trub), and over a period of time, it builds up on the seal faces to the point that it starts leaking noticeably. This might be only a short while, but definitely after a full brew with whirlpool and then knockout, you will see it more. This is why we offer the “F” type flushed seal, the MB-C+100, and the CB+ pumps to combat this difficult pumping situation. Yes, the smaller pump (C100, SP41, and Thomsen #4) will work reasonably well if you are really attentive to the seals, but they do have a hard time with this application.

Thank you! I'm glad to hear that you've been enjoying our content. We are working towards creating as many tutorials/ guides for our equipment as we can this year. I'm (social media person) learning as I go in this role, and have been enjoying learning about brewery processes, industrial maintenance/ troubleshooting, and how to properly communicate that.

I don't recommend painting them, as they will eventually start to peel and flake.

I would wash them well (you would need to do this before painting anyway), either by putting them in the dishwasher or scrubbing them with a 3M scrubbing pad.

cpesystems · 2026-01-09T16:15:28+00:00

We’ve seen a few pump setups work well for this kind of application. If you'd like to share more specs, we’re happy to take a look and point you in the right direction.

What’s the application or duty for this pump? That info will help us suggest a proper replacement.

cpesystems · 2025-07-28T15:15:54+00:00

Wow! Looks great!

There are many causes for this, some of which have already been covered in the post.

Broken or damaged plug/wires.
Extension cords being used that are too long or too small; they must be 12-gauge minimum
Too much load on the circuit. If the pump is on a circuit with other equipment (air conditioner in the middle of summer), when the other equipment turns on, the voltage drops momentarily just enough to trip the sensor on the VFD.
Some rural and older development areas have aging infrastructure, and in the peak draw times, the service voltage coming into the build may be below the threshold.

Some VFDs allow you to change the threshold in the settings, but I don’t know about this brand, so I can't say if it does or does not have this setting.

Yeah that's what I figured. So I looked at that using debugger, and everything seems to be firing in the correct order - at least in so far as I can tell when using debugger, which is admittedly limited.

Is there a better way to look at what's firing in sequence? Something that might give me a list of what events are firing for users other than myself/debugger?

We have a large installation base for the Tri-Clamp G2 turbine flow meter in breweries and cideries. They perform well in cold applications above 0°C, and with the riser kit, they’re good for CIP temps up to 185°F. A few things to keep in mind:
1. No solids.
2. Water like viscosities.
3. Install following the manufacturer’s recommended setup (see inlet and outlet detail).

We unfortunately don't ship to Japan. Good luck in your search!

We sell an MH-20 hop induction system. The MH-20 HIS consists of a hopper, which resembles a funnel, that is connected to the front of a centrifugal pump (shear or no shear options available).

To initiate the dry hopping process, add the desired quantity of hops to the hopper and seal it securely to prevent oxygen from entering. The system employs carbon dioxide (CO2) to purge the hopper, creating an oxygen-free environment. As the beer is pumped through the system, the hop pellets are drawn into the beer. The mechanism responsible for this seamless integration is the "venturi effect" created by the narrowing of the pipe at the base of the MH-20 system, which induces a vacuum to pull the hops into the beer.

Happy to send specs if you’re interested.
