REV A (05-01-09)INSTALLATION MANUAL – D5Piers SetupThe foundation that equipment is mounted over is typically pre-cast per Dynapump requirements,but also may be poured in place.Perform the following steps:1. Grade the site (approx. 25’ x 25’) and scrape all dirt/debris off existing well pad or levelnominal ground level.2. Provide adequate drainage by allowing excess water to drain. Poor drainage may result in thefoundation settling unevenly, causing undue stresses in the foundation. This may cause pumpmisalignment after a period of time.3. Excavate an area deep enough to position pre-cast concrete piers per the layoutrequirements. Foundation design/soil improvement is based on soil conditions at the wellsite, and the owner asumes full responsibility of the design/quality of the foundation.Pumping UnitPower UnitFigure 2. Piers Setup4. Add enough aggregate base to create a height of 36 inches between the wellhead and the topof the nominal pier level (see Figure A-2). The minimum height will assure full stroke lengthof the pumping unit.5. Lower the pre-cast piers into the aggregate base using a crane or other hoist equipment (seeFigure 2).6. When finalizing the pier placement, verify that no concrete material hangs over the aggregatesoil unsupported, and that the pumping unit will be able support full load bearing capabilityfrom the pumping unit. Site layout is based upon soil bearing strength of 6000 psf.7. Position the pad in accordance with Figure A-3.Skid Installation and Pumping Unit PlacementSkid mounting and pumping unit site installation must be performed at the same time to assureaccuracy in equipment placement. The paragraph in Section 5 “Installation” titled, “Skid UnitInstallation and Placement of the Pumping Unit” describes this procedure.SECTION 2 – SITE PREPARATION5
