Syrup tank and pump layouts

Recommended Posts

Gear pumps are the way to go, even for syrup, but the 5mm trash pumps do the job well enough at a lower cost.

 

We have a couple of 12v diaphragm pumps on smaller tanks, slow when the sugar is cold, ok if you can heat the sugar up.

Some changes here.

For now I have to think electric. This is it.

 

I remembered that I used to use an electric stick/drum pump(maybe the progressive cavity pump category......?).

The brand was Lutz(full plastic) and it pumped the salty water(with plenty salt crystals in it) easy as.

 

I play with the idea to build one since a Lutz pump(or similar) are dear.

 

Current idea for design:

- 1.5" pipe from Mitre10. Maybe made out of 2 or 3 pieces. Long enough to fit in a drum.

- the top end will have a T + a hose to return the liquid into the drum

- inside the pipe will be a SS rod(they are not cheap). I wonder if I can get a 1.5m piece with 6-10mm diameter. Apparently the ones over 1m are 12 or 12+mm thick

- I will put homemade propellers on the rod starting at the bottom

- I will add brackets(bits of SS) to keep the rod centered. One bracket at the bottom, and more where the pipes will be joined and above the T 

- above the T will be a seal to stop the liquid going up

- it will be powered from the top with a drill gun

For a petrol pump from TM where can I get fittings? Now they are for $200.

Suppliers on TM or a farm supplies store like RD1 or DeLaval or a local pump suppler.

I've got most of my hoses and fittings from the Hose Shop in Avondale, they also have an East Tamaki branch.  Nothing is cheap.....

Falloons at Dairy Flat has a really good selection, and not blindingly expensive.

I plan to have my syrup mixed in a 200L plastic drum. And use a petrol pump.

Is it a good setup if the pump's inlet will be attached close to the bottom of the drum while the outlet will fill the drum from the top. The pump should have enough power to push the syrup 1m up.

Any suggestions are welcome.
