Overview
The Sethco Sealless Series pump from Met-Pro Corp is a bearing-free, sealless centrifugal pump engineered for handling corrosive industrial liquids. Sethco, a division of Met-Pro Corp., manufactures high volume sealless drum pumps. This design philosophy eliminates the most common point of failure in conventional pumps — mechanical seals — making it ideal for chemical processing, metal finishing, and industrial waste treatment applications.
Key Features
- Sealless construction eliminates the major cause of pump failure and can run dry without costly damage to the pump if it is run dry for short periods after drum or container has been emptied.
- More effective vapor seal, which improves bearing life.
- One piece tube construction, fewer pump parts and new bearing cup ensure reliability and extends pump life.
- Wide vane axial impeller efficiently moves high viscosity and specific gravity liquids up to 4000 ssu.
- Empties a 55 gallon drum in less than 2 minutes and a 500 gallon tank in less than 13 minutes with electric motor.
- New bearing cup design allows fast, inexpensive, easy to do repairs.
Technical Specifications
Sethco Sealless Series pumps are available in multiple configurations depending on the specific model variant. Common specifications include:
- Sealless, bearing-free design
- Corrosion-resistant materials (polypropylene, CPVC, PVDF)
- Capable of transferring corrosive liquids at flow rates up to 35 gpm.
- Maximum viscosity capability: 4000 SSU
- Multiple tube lengths available (30″, 40″, 50″, 60″)
- Standard 1.66″ (4.2 cm) tube diameter
- Electric motor driven (motor specifications vary by model)
- Designed for portable and stationary applications
Typical Applications
As a division of Met-Pro Global Pump Solutions, Sethco designs and manufactures corrosion resistant pumps and filtration systems for the chemical, industrial and metal finishing industries. Common uses include:
- Transfer of corrosive chemicals and acids
- Metal finishing and anodizing operations
- Waste treatment and disposal systems
- High-viscosity fluid handling
- Portable drum and bulk container emptying
- Industrial wastewater management
Compatibility & Replacements
Compatible With
- Standard 55-gallon drums and industrial containers with universal bung openings
- Carboys, vats, and oversized tanks
- Electric motors (TEFC, single-phase and three-phase options)
- Standard NPT suction/discharge connections (sizes vary by model)
- Industrial chemical handling systems and recycling operations
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The Sethco Sealless Series replaces earlier-generation drum and vertical centrifugal pump models with similar displacement and flow requirements. Common predecessor models include older seal-dependent designs from Met-Pro and competitive manufacturers.
Works With
- Three-phase and single-phase electric motor drives
- Variable frequency drives (VFDs) for flow control
- Portable and stationary mounting arrangements
- Standard industrial hose and piping systems (1″ to 2.5″ NPT connections)
- Drum skid and transfer cart assemblies
