The Myers SSM33I is a rugged, heavy duty cast iron 1/3 hp Submersible Pump designed for demanding drainage jobs. The SSM33I's recessed, vortex impeller provides a clear, unobstructed passage in the volute case for superior solids handling. Its 1/2" solids handling capability allows it to be used in a wide variety of drainage and effluent pumping applications. Heavy duty cast iron construction ensures that the SSM33I will perform for years to come in most installations.

Advantages By Design
Durable motor will deliver many years of reliable service.
  • Oil-filled motor for maximum heat dissipation and continuous bearing lubrication.
  • Shaded pole motor eliminates starting switches.
  • Recessed vortex impeller provides free flow-through passage for solids and liquid with minimal radial loading for long bearing life.
The SSM33I is engineered for many years of maintenance-free operation.
  • Automatic models available with piggy-back float or vertical switch. (Both mercury free)
  • Pump can be operated manually by unplugging piggy-back switch and plugging pump directly into outlet (Automatic models).
  • Heavy cast iron motor housing and volute case dissipate heat, allow motor to run cooler for extended life and resist corrosion.
