Engineered Canned Motor Pumps

Customized, heavy-duty canned motor pumps for challenging applications that require extra thrust capacity.

Design Features

Design Features

Hayward Tyler canned motor pumps offer a combined pump and motor on a common shaft, wrapped in a pressure boundary. This eliminates the need for mechanical seals and hence eliminates the chance of a process fluid leak, making it a highly reliable solution for critical applications.

  • Thrust bearing provides reliability during upset pump conditions
  • No mechanical seal means no leakage
  • Inherently safe
  • Double layer pressure boundary containment
  • Self-lubricated bearings – no external lubrication system needed
  • Eliminates pump and motor alignment – common shaft
  • Low noise
