Can i run two pumps of my liquid logic gardiner system controler? If so how would it work?

[Spruce]

I wouldn't even try.

We have Varistreams and they are rated at 10 amps. Each pump will draw 8 + amps according to Shurflo's specs on full. I guess that we would drawn around 6 amps with our flow rate and equipment. Double that for 2 pumps would mean the controller is overloaded. If you are lucky it may blow a fuse, if you are unlucky you may burn the whole controller out IMHO.

You'll melt the controller most likely,..

thanks for the heads up guys

do you know matt lwc
he works his pumps with a
very cheap controller he's based in oswestry
ask him when i say cheap i mean cheap
under a tenner

In an ideal world the advice would always be if you are running a twin system use two controllers. It will give you better results as you can control each pump separately and even have different flow rates and poles set up on each system.

The controller is designed to work with one pump ideally a 100psi 5.2Ltr per minute Although it will work with a higher rated pump. The Controller has a range of built in protection systems

1. Fuse
2. Diode to protect against reverse polarity
3. Over Current management

1. The liquid logic is also rated up to 10 amps and has a 7amp fuse,you need to look at the maximum ampage of your pump when running flat out X this by 2 if you exceed this the fuse will blow.
We recommend a the fuse supplied is always fitted.

3.  The liquid logic also has a built in safety shut down If it detects current (amps) above 7.5A it will shut down to protect itself and display the message OC = Over Current.

As Spruce rightly points out 2 pumps will draw twice the ampage so you need to take this into account. Every system is different set up to individual requirememts - However in testing we find a 100PSI 5,2ltr per minute pump will draw between 3 and 5 amps so double the high end and the controller will shut down (provided it is fitted as per our instructions)

Also the higher current draw per hour of two pumps will reduce how long each charge will last.

Provided the controller is fitted as per the manufacturers instructions and the fuse is in Line (on the positive red cable) between the battery and controller.
It is possible to run two pumps with one controller But you will have to consider the point above + the DE calibartion will have to be adjusted with both poles running. Otherwise you will find that Dead ending one pole and pump will shut down both pumps.
Also You will need to consider it may effect flow rates to both poles .

Bottom line is the controller will do it, However the controller is designed to work with one pump and you will risk overloading the controller. Advice is get another controller its well worth the investment to have a back up and additioal protection on your system.

- I would suggest you think about a charging controller that has a split relay built in or get an auto electrician to fit a split relay.
Remember though even with a relay the alternator will only trickle charge a leisure battery while the engine is running

good advice there thanks in all the vans iv had in the last few years i always just have leads from the battery under the bonnet to my car battery running the pole system never had a problem with that and never have to charge anything:)

yer i know matt he runs a maplin controler about £16 i think and only one pump for two reels but there flow rate is slow. i use more water than they do because im quicker haha only joking

It isnt slow! and we're much MUCH better than you and you know it, now kiss my feet

[Deangsi]

Lol how are you mate? Keepin busy i manged to fix the old shurflo me n mark had alot more powerfull than the one im using. Btw your van looks tidy inside mark showed me other day:)

[nokmond]

Have you a link to the maplin controller?

there you go  good little controlers think mine lasted about 2 years before it broke in the end probley me that broke it tho. but at £15 you cant go wrong all you do is put it in a circuit box which you will also find somewhere on this site

[Deangsi]

you also need to wire in a fuse and a on off switch for it  altogether should only cost £20 with everything
