This information is important to those companies that have
customers with Dankoff/Flowlight Booster Pumps and Slowpumps.
These pumps use DC motors to drive rotary vane positive
displacement pump heads made by Procon. Windy Dankoff developed
these pumps about 30 years ago and I think thousands have been
sold. Other than the quirkiness of their need for fine (10 micron)
filtration on the intake side, and the relative unreliability of
the optional dry run protection thermal snap switch, the pumps are
exceptionally well-made and long-lasting, in my experience.<br>
<br>
Early (before around 1998) pumps were sold under the "Flowlight"
name; then under "Dankoff Solar Pumps" name until Conergy bought
Dankoff around 2004. The pumps had Conergy's name on them until
around two years ago, when Conergy closed its sales and
distribution of water pumping, solar thermal, and wind products.
Innovative Solar bought the water pumping line and restored the
"Dankoff Pumps" name. Innovative Solar became Argand, and changed
their distribution model in order to not compete with their
dealers (attaboy!); Dankoff Pumps, while owned by Argand, is
wholesale only; new dealers must place a minimum stocking order.
The pumps continue to be manufactured here in Santa Fe by the same
folks that have made and serviced them for years, and quality and
support remain high. <br>

The Procon heads wear out. New replacement heads are available
through Dankoff Pumps (and probably other sources as well).
However, the heads are rebuildable, and the cost is much less than
new. We always ask customers for their old pump heads in exchange
for new or rebuilt ones. The rebuilder is Edco Service Center,
8220 Belvedere Ave., Suite F, Sacramento, CA 95826; 916-454-1445.
The contact person there is Sandie, <a moz-do-not-send="true"

Recently we learned some critical information related to pump
rebuilding: the heads may rebuilt in many configurations, and it's
essential to specify that the <b>pump heads must be for potable
water applications</b>. This has to do with the amount of lead
in various internal components. According to Sandie at Edco, you
must specify a <b>114E head</b>. According to Matt at Dankoff
Pumps, the full designation is <b>114E240F11XX</b> for the
Booster Pump head and this should be specified in full. All
original Booster Pump and Slowpump heads were acceptable for
potable water; however, due to a mixup of indeterminable cause, we
were recently sent a set of 104 rebuilt heads, which aren't
(according to the State of California) suitable for potable
applications due to lead content. To their credit, Edco will
re-rebuild these heads to potable standards at no cost to us save
shipping, but this seemed to me to be a good opportunity to share
this information widely with other water pumping Wrenches.<br>
