Air powered diaphragm pumps

I have a Wilten(sp) pump that came with the Leader Clear press. It's amazing how much control you have with pneumatic over the old Oberdorfer. Filtered 3½ gallons of some not so warm syrup - about 110° - last Saturday. Although a little slow, it chugged right on through it without issue.

Dont want to hijack the thread but my pump died tonight. Whats the advantage of aluminum vs the kylar? With a diaphram pump the liquid doesnt even come in contact with the housing. Correct? Assuming they work similar to a sprayer pump. Got to order one asap. Been an expensive year for a hobby.

Yes the syrup contacts the housing.

I don’t see why either wouldn’t work. IMO air pumps are like an RO. You will never go back.

Whats preferable. Aluminum or kylar?

How do you like the plastic plate filter press? What size air compressor do you run your pump with? I'm so sick of cone filters, I'm usually doing 8-9 gallons a day and it's just so hard to keep up with them. Very interested in the Leader plastic press but $$ of course!

For me anyway; the best part of it is the ability to see how much cake you have built up and how much syrup is left when you've emptied the drawoff tank.
It's got a Wilden pneumatic diaphragm pump.
I use a Rolair VT25BIG 2.5-HP 5.3-Gallon compressor that's rated at 6.5 CFM at 90 psi. Link here... https://www.rolair.com/products/air-...-carry/vt25big
Nice wheeled unit with lots of cfm but is noisy. All in all, I'm very happy with both the compressor and the Clear Plate set-up from Leader.

Still trying to sort this all out. Unfortunately the pump catalog online distributor has some inaccuracies regarding max temp. some of their advertised Yamada pumps can handle. Poly pro body pumps can only handle up to 180F and not 212F. The diaphragms may be ok, but not the pump body.

I noticed the same thing with the pump I got from them. Tag on pump says 212 I think, but was supposed to handle 248, not that I need it. But I called and they assured me I have the hytrex parts, so am good to 248. I have the 15BAH.

How do you like it? I've narrowed it down to the BAH or BAT. The BAT is a little more $$$ but it has PTFE diaphragms, o-rings and seals. The BAH has Hytrel diaphragms but Buna-N o-rings....

Their stated max. temp. ratings are related to the line of pumps, and not the specific pump however. At least that is what they told me today.
