Cast Iron End Bell

Most common “56C face” motors manufactured today utilize a die cast face that is made of relatively soft material that can easily be distorted by the heavy loads placed on it. For centrifugal and regenerative turbine pump manufacturers, this is especially troublesome where pump ends are close-coupled directly to these soft motor faces and are subjected to high loads during assembly processes, transit or installation. The resulting face distortion can easily cause pump “lockups” or premature failure due to wear caused by mechanical interference between internal rotating and stationary pump components. In other cases the threaded mounting holes in these aluminum C-faces can be stripped if high force is applied to the pump head or bolts during product assembly or installation. The 4856C Series end bells are specifically designed to prevent these problems by the use of a high strength cast iron material that is substantially more resistant to high stress loads. This material also minimizes dimensional distortion in the eventuality that end users overstress either the pump bolts or casings during their installation or maintenance procedures.

 

Compact Design

The DLT Electric 56 Frame Dual Face ODP pump motors are unique in the industry for their power and performance capabilities. This design requires no bulky external conduit box to use up valuable cabinet space. Connections are made inside the rear end bell (opposite the pump) where the starting capacitor is also located for best use of space. A Conduit connection is strategically located to allow “hard” or “soft” connections depending on customer requirements.

Cool and Quiet Running

The DLT Electric 56 Frame Dual Face ODP motors run cooler and more quiet than many commonly available pump motors. This is accomplished by the use of an efficient electrical design in conjunction with enlarged cooling vents, which have been incorporated into the front end bell. These vents serve to minimize fan noise, and provide extra cooling airflow to compensate for installation into tight enclosures typical of OEM applications.
