Available as an option on all ITT A-C Pump wet-pit column pumps, the "pull-out" design substantially reduces maintenance and downtime costs by allowing removal of the inner element without disturbing the suction bell, column, discharge elbow, or discharge piping. Column size for a given capacity is not affected by the "pull-out" design and there is no sacrifice in pumping performance. The sliding and conical fits assure proper alignment upon reassembly. The inner element is completely removable from the top of the pump thus eliminating the need to drain or enter the sump during maintenance. When time comes to restore system efficiency, simply replace the wear parts and your pump is ready to log years more service. ITT A-C Pump strongly recommends the "pull-out" option on all installations since downtime for planned inspection and service outages can be significantly reduced.
