From:                          Mike Thornton, Purchasing Manager


Subject:                      Purchase request 43538 to the Sanders Company, Inc. to purchase Variable Frequency Drives for the Environmental Services Department


Staff Recommendation:

Staff recommends approval of purchase request 43538 to the Sanders Company, Inc. for $70,952.00 for the purchase and installation of Variable Frequency Drives (VFD) for High Speed Service Pumps 1 and 2 located at the Main Water Treatment Plant.



The purpose of this purchase is to obtain VFD’s which will serve to maintain a firm pumping capacity during a high flow or fire event. High speed service pumps 1 & 2 do not use VFD’s which limits when these pumps can be used.


This purchase and installation will allow the City to operate all high service pumps in the auto mode, as well as, equalizing the run time on all pumps.  VFD’s provide additional benefits such as reduced power consumption, more efficient motor operation and pumping.


The Environmental Services department has standardized on Danfoss VFD’s.  This purchase will add to Danfoss units already installed within the system.  Sanders Company, Inc. is the manufacturer’s exclusive representative for its variable frequency drives in the State of Florida.  Both the price quotation from Sanders and the sole source letter from the manufacturer have been attached for your review.



1.  Approve the purchase from the Sanders Company, Inc.; or

2.  Such alternative action as the Commission may deem appropriate.


Fiscal Impact

This purchase of $70,952.00 is budgeted and funds are avialable in the current fiscal year.
