High temperature small water pump
High temperature small water pump
(OP)
I am trying to source supply small potible water pumps for a domestic product I am designing for mass production.
600 ml/min - 10 gal/hr
99C - 210F
3 bar 43 psi
120/230 AC supply.
The small size and reletively high pressure would suggest a solenoid pump would be ideal however the temperature blows them out of the water. Small impeller pumps can do temp. but pressure is too small and usually only come DC motor versions.
Needs to be low in cost for a domestic product. Less than $30.
There are plennty of high spec. pumps like gear and vane but they are usually quite costly.
Any help welcome?
Thanks

I saw some small diaphram pumps which use rotary motor to oscillate diaphram. Most of these use DC motors which I hoped to avoid. AC motors seem to be much bigger (over 100W)

A direct motor-driven diaphragm pump may be possible (for more money), but the diaphragm will need to be quite stout to withstand your combination of P and T. A cheap rubber diaphragm won't likely do it for you over the long term. And the reason they use DC motors is the torque required, which is substantial- you either need a DC motor or a large gear reduction or both.
