I have a climate master HP without a built-in desuperheater pump, it has the in / out ports, but I need separate pump unit. The only one I can find is a Bard unit at like $800, which seems crazy high. Anyone have a source for such a pump kit? Thanks

Manufavcturers have 33w to 180+ bronze pumps on line
TACO and Armstrong and Grundfos and B&G air and wet rotor and variable Grundfos and WILO for most of those applications. Perhaps see if who sold the unit to you will give you a climate master tech number or etc. Those pumps are replaced by their OEM sales and probably have a plan to follow for you.

It's not just a pump, it's the controls and temperature sensors that make up the whole unit.

What model heat pump do you have?

along docjensers lines, i thinke as written, the OEM will have a plan for you , with a plan of those sensors greg references...

I have a 2 ton commercial line unit that did not have a built-in desuperheater pump. It was part of a much larger order on a commercial project and they added one extra HP for me, got it at below cost.

Any cir will do but u also need temp control. The bard has both but is plumed in half inch OD. Was not aware CM had DSH package witout circulator.
