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>

Dankoff Pumps website is currently <a class="moz-txt-link-abbreviated" href="http://www.Dankoff-Pumps.com">www.Dankoff-Pumps.com</a>. Note the
hyphen; <a class="moz-txt-link-abbreviated" href="http://www.Dankoffpumps.com">www.Dankoffpumps.com</a> takes you to a (currently closed)
online store, with referral links to Dankoff Pumps for dealers who
want to become dealers. Dankoff Pumps will soon be either moving to
or adding <a class="moz-txt-link-abbreviated" href="http://www.DankoffSolarPumps.com">www.DankoffSolarPumps.com</a> as well, I understand, but this
hasn't happened yet. Contact Dankoff Pumps at

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 class="moz-txt-link-abbreviated" href="mailto:sandie@edcodistributing.com">sandie@edcodistributing.com</a>.<br>
<br>
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>
