Why no demand pumps on SteamAction?

[Giorgio]

I'm in the market for a new TM and I notice SteamAction doesn't offer freshwater demand pumps on any of their machines with submount freshwater tanks.

Why is that? What am i missing?

Also, there's no demand pump on their 2026 Nike model either.

what gives?

I haven't watched the video yet, but after studying up on several manufacturers systems and building my own machine i learned that cleanco pto's don't use a transfer pump when transferring water from onboard storage eighter. That's because where most machines need the supply/ water box to be higher than the pressure pump inorder to gravity feed water to it or it will loose prime. And a pressure pump to supply water to the waterbox Its my understanding that cleanco uses a Cat CP5 pressure pump. This pump, insteat of relying on gravity to feed it will suck the water up into the pump eliminating the need for a transfer pump and for that matter a waterbox

That's what I was thinking.

The Cat 5 pump on my old Vortex would draw water from the belly tank. Once in a while it would lose prime but that was usually do to a loose hose connection on the draw side.

So, if a Cat 5 can draw water from a belly tank maybe all high pressure pumps can draw water from belly or saddle tank.

Now, I'm wondering if the fresh water demand pumps the industry has been pushing all these decades are totally unnecessary and were just added for overall expense and complexity for something that was never an issue to begin with.

Your thoughts?

Yes

Not really i run hypro 2340bp pumps and before that i used hyra cell diaphragm pumps neither would suck water up and requires water to gravity feed inorder to prime or stay primed . The cat cp5 is an exception to the rule and not the norm i think most high pressure pumps on the market are that way at least most all diaphragm and plunger pumps are i don't know about piston pumps,rotary vanepumps etc.etc.

I’ve owned Prochem’s, TCS units and Cleanco’s. None have had transfer pumps.

It makes way more common sense for manufacturers to upgrade the high pressure pumps to something that can draw water than to sell us an entire new demand pump circuit which takes up valuable real-estate and added complexity.

I feel like I'm taking crazy pills!
