What is the difference between jebao dp-4 and dp-4s dosing pumps?
Thanks

Seems ds is a newer design...box is slightly different...not sure about the program functionality..
Seems to be same dosing heads too..

I meant dp-4s (not ds-4s)
It looks like dimensions of the box are the same. I have dp-4 and after 4 years does not work properly.

dp4s is a slave module while dp4 is stand-alone one.
You can extend 4 more pumps, if you add a dp4s to your dp4.
If your dp4 is out of order, you must buy a dp4 not dp4s.

dp-4s is the slave pump of DP-4 ,it comex no power supply and should be connected use with DP-4
