Canned sealless centrifugal pumps combine a centrifugal pump and electric motor in a hermetically contained assembly. Unlike conventional centrifugal pumps, they do not require a dynamic shaft seal between the motor and pump, helping reduce the risk of process-fluid leakage.
The motor rotor operates within the contained fluid area, while a corrosion-resistant containment shell isolates the stator and electrical components. This design makes canned-motor pumps suitable for handling hazardous, toxic, corrosive, high-temperature, or otherwise difficult process fluids.
DAC Worldwide’s Canned Sealless Centrifugal Pump Dissectible (Crane/Chempump) (275-140) is constructed from an actual industrial pump restored for realistic classroom and laboratory training. Pump examples from manufacturers such as Crane and Chempump are selected according to availability and industrial relevance.
The dissectible allows learners to examine the construction and component relationships of an industrial canned-motor centrifugal pump. Primary operating features are retained, and replacement hardware is provided where necessary.
The pump is cleaned, restored, and painted with a high-durability urethane coating where appropriate. It is mounted on a modular, 7-gauge formed-steel baseplate with provisions for benchtop, workstation, and storage rack mounting.
An applicable installation and maintenance manual from the original equipment manufacturer is included when available to support equipment-specific instruction.
Learners can use the dissectible to explore:
Product appearance, dimensions, and weight may vary according to the make and model of the industrial pump supplied.
