0-10v circ pumps

Hvac tech_2

Any recommendations on a 0-10v boiler pump to be controlled by a Lochinvar knight boiler

There some listed in the older I/O manual... however they are around $500 IIRC.

*edit* I should note I believe those were ECM circs

Depending on the size, I see contractors using the Grundfos Magnas over at the Lochinvar VIP contest site

We have a complete lineup of "VV" 0-10Vdc circs in our 00 Series lineup. Been available for years (back when variable flow and energy efficiency wasn't as important as it is today).

Any ECM 0-10V circs?

For my setup (boiler primary loop, P/S), all I need is ~3-5 GPM with 1-2' head loss.

Nothing today sorry (patience please).

Back in my WILO days that would have been a perfect application for their little 24 Volt Geniax...

In Europe, anyway.

there are a good number of the small PWM circs available across then pond of various brands. We use some of these Wilo in the Satellite units we build for Euro markets, and some with Grundfos brands.
