can this handle organic solvent, petrol or oil?

I wouldn’t suggest anything harsh is put through this, it’s 3mm silicone tubing which I would suspect won’t be suitable for all solvents or oils. That said, it’s pretty cheap to buy 10m of it and easy to replace on my unit so if it’s only for a limited lifetime and you don’t mind repairs I don’t see an issue

how is the pump speed controlled ? PWM at 12 v dc, or by voltage regulation , or by current regulation ?

Hi sorry for the delay.been out of the country the parasitic pump output can be controlled by voltage ..haven't tried it on pwm so cannot comment.the pump works by squeezing a flexible pipe and the flow is therefore in small squirts .I am using the pump as a dosing pump in a hydrophinc system. The pump has a good pressure and a I would think a good height best of luck with your project. Ron
