CHANCS 385 Diaphragm Self-Priming Pump DC 6V-12V Motor Shock Absorption Water Pumps for Daily Water Cycle of Fish Tank and Home Appliances

I use this pump to circulate ice water from a Dometic Go 11L container through silicone tubes that form a cooling vest. I power it from my power wheelchair. It helps to reduce spinal inflammation and pain as well as makes trail rides in the sun a more pleasant temperature.Because the diaphragm pump can move air as well as water, it will prime itself and can be mounted above the draw tube on the outside of the tank. Other types of pumps, such as the common centrifugal pump would need to be mounted inside the tank, which would cause problems with sealing the wire pass through.The pump is not too loud, and the included rubber mounting rings help mitigate sounds also. The flow rate is good for this application.

Günstig aber voll ok. Erwartungen erfüllt.

In initial testing, I took a 2 gallon bucket of water whose bottom was approximately 2 feet below the pump, and limited my bench supply to 1A output.At both 6v and 12v, the pump itself was dead silent, the only audible sound being the water returning to the bucket.The performance was better than expected, as was current draw. The rubber mounting sleeves were a nice bonus.5 stars, would definitely order again.

一緒に買ったポンプの流量が表記の1/10ととんでも性能だったので、ついでに測定してみました。定電圧電源と2Lペットボトルを準備して空になるまでの時間を測定。1分ちょうどで空になったので、表記通りの性能は出てると思います。耐久性はまだ買ったばかりなので分かりませんが、モーター部分は剥き出しのため耐水性は無いと思われます。まぁ、水中ポンプじゃ無いので耐水性はどうでもいいんですがw
