We do not make either filter 3161 or 3162 as a DC version, for 3161, we had planned a 0900 pump in DC, but due to the cost and likely low volume of sales this plan was cancelled. For 3168, you could use the 2500.000 pump and for 3163, you could use 6055, but in both cases the pump would need to be turned down to a very low speed.
Thank you for your reply, because I saw on the Internet that tunze has a 900dc motor, but I can't find it recently, because I am a pure tunze dc module, and the protein machine is 9004dc, there are many, I want to use a separate tank as a preparation . In addition, between 2018-2020, I purchased the tunze equipment on the French website, and there have been some failures recently. I don't know if I should contact you for maintenance, or should I contact you in Germany? I am from Taiwan
Yes, we had planned to make a 0900 DC, but with the shortages of components and expected low sales, this plan was cancelled. I would contact the distributor in Taiwan or the main office in Germany for repair.
