When I should specify a Solenoid dosing pump and a Motor dosing pump?
When I should specify a Solenoid dosing pump and a Motor dosing pump?
(OP)
I have to specify an acid / basic dosing pumps as a neutralization system. The flows are 0.07 and 0.005 l/h respectivaly. The discharge pressure is atmospheric (to a basin pod). Shall I specify a motor dosing pump or a solenoid dosing pump? and why? I have seen in the market that motor pumps go down as low as 0.15 l/h, so, it seems that a solenoid dosing pump sounds to be the right choise for such low flow and pressure. With this problem in mind the final question to answer is : when to use a Solenoid dosing pump Vs to use a Motor dosing pump? Can anyone help me on this regard? Thsnks...

The flow is very low contact your local dosing pump supplier for better result as per the design.

Solenoid pumps are considered to be throwaways instead of being repairable. Solenoid pumps won't stand up to 24/7 service. If the application is critical, you would need a spare for the solenoid pump plus additional parts inventory to repair the solenoid pump.
For the small flows that you mentioned, you may consider diluting the products. It will be easier to pump a larger flow and will improve the accuracy of pumping.

For such a use the performance, price and dependability (Eg. price/lifetime cost) should be the deciding factor. Describe performance / operation and open for suppliers argumentation and documentation of their product The quality of performance, support, service, cost/lifetime and future availability should then give the final decision.

That motor driven pump is a better idea. Because it's more reliable and can run 24/7 perHr.
About the dossage of your chemical injection. Try to dilute it first before injecting. It is easier solution than you must search for the spesific dosing pump (I never heard of a dosing pump that will give that small of amuount of chemical dosing though)
