osmolator metering pump question

[fatoldsun]

Hi
Was trying to figure out if I can I use the osmolator pump to push my ATO water up about 10-11' of head with a total travel of 30' (including the head) . Reason is I'm making my RO/Di in the basement and the tank and sump are on the floor above and offset by about 15'-20'. I ran vinyl tubing and a couple runs of CAT-5 to the water making station on the basement and I am trying to figure out of I can use the Tunze metering pump that comes with the Osmolator or if I need to pick up an aqua-lifter. I found this on-line for the metering pump (5000.02) - Metering pump capacity: 2.95ft: 13.74gph, 4.92ft: 12.42gph, 6.56ft: 7.13gphMax. This suggests to me that it isn't strong enough.
Second part of that question "“
Can i use the osmolator to control a non-Tunze metering pump, like an aqualifter?

I don't believe the Aqualifter is capable of that sort of range either. You could use the 3150.110 switched socket to run a pump of your choice. I suspect you will need something like a high head Iwaki.

Thanks Roger
I was wondering if you could give me some insight into how you think that setup should look? I ran CAT-5 before I closed up the walls. Can I use CAT5 to extend the remote(s)? Should I locate the head unit/controller at the water source and run the sensor lines down to control the unit remotely or is it better to keep the unit at the tank and remotely control the relay (3150.11)? is one option the preferred method of remote control? If, in your opinion there is no difference I would assume controlling the 3150.11 remotely would be best since it's one piece instead of the 2 sensors.
Thanks again for all of your help

CAT 5 would be of no use, the osmolator is required to use 3150.110. All 3150.110 is is a switched socket a relay opens a 115V outlet in place of the 12V DC osmolator pump. You would run 22 gauge speaker wire to extend this connection from the osmolator to the switched socket. The controller would be near the sump, the sensors are hard wired to the controller with about 7ft of wire. The pump would connect to the socket in the basement, stock you would have about 10ft of wire from controller to the socket, but speaker wire could extend this connection.

CAT 5 would be of no use

Well, here's hoping the CAT5 will be an adequate substitute for speaker wire - is there something proprietary to the unit that would not allow me to use the CAT5? I think it can be used as a substitute for most low voltage stuff. I know that it is used as high-end speaker wire because they are unshielded twisted pairs. For speakers, it just requires using 2 pairs for each channel... I ran 3 runs down to my RO/Di holding tank so I have plenty of options with that but my walls are all closed up so I'm limited to finding a way to use the CAT5s that are there and also the 3/8" vinyl tubing so I don't think I can use a pump as large as the Iwaki

All the connections are very simple DC 2 wire connections, I don't think the thin CAT 5 wires could handle the current requirements of 12V at about 1200mA I think the resistance will be so high on the thin networking cable that they will overheat and fail or trigger the controller to cut power to the pump/ switched outlet from excess current draw.
