The noise is reduced pumping water and is on some padding. I'm sure the vibration wouldn't bee too bad if it was screwed down.




Here it is running at a constant speed at 100 pwm.

The high pitched buzz is the motor and the popping sound is air going through the tubes. It might not be as loud is if it was pushing liquids.

I'm not pumping enzymes into the tank, I'm controlling the flow of tank water into an Aquamedic Blue nitrate reactor. Its currently fed from a tee on the output of my canister filter, with a needle valve to control the flow rate and a solenoid valve to turn the flow on/off based on a control system running on my Raspberry Pi. I'd like to leave the plumbing as-is and just replace the solenoid with the peristaltic pump, since that way I'm running clean filtered water into the nitrate reactor...

regards
Don

As for the pressure/leak question, I don't see it affecting the pump.
Why would the input have pressure? I'm assuming you're pumping in some nitrate eliminating enzyme.

1. how noisy or quiet is it when operating at low speeds? its going to be in the cabinet below the aquarium in my living room...
2. can it withstand a bit of pressure on the input without leaking? current input to the reactor is from a tee on the output of my canister filter. I guess i could switch it to pull water directly out of the aquarium, though...

thanks
Don

Not saying a check valve is a bad idea. Just saying it isn't essential.
