CONVERT YOUR PUMP TO "NO-SEAL" AND ELIMINATE SURFACE LEAKING
The "No-Seal" Vertical Turbine
The "No-Seal" pump is designed to meet the rigorous requirements for the automotive, steel, mining, chemical, petrochemical, and petroleum industries, in addition to numerous other industrial applications. A key factor in its design is a unique bypass/pressure break area and slinger. Leakage is confined to the area below the discharge head. A hydraulic seal is created preventing the pumped liquid from reaching the area where the shaft passes through the discharge head. Since no liquid is present, no leakage is present in this critical area. This factor is of prime importance to the pump operation. It removes the possibility of undesirable surface leakage often present in a conventional packing box design. Since no mechanical seal is used, seal failure is eliminated. The "No-Seal" pump is designed for application when pumping from sumps or vented tanks.
Features
Operation Description
Step 1: As the pumped liquid passes from the bowl assembly into the column, the main flow continues upward into the column case and out through the pump discharge head.
Step 2: The small amount of liquid, which is forced past the close-fitting throttle bearing in the column case, strikes the slinger and is expelled out the bypass ports to be returned to the source of supply. A sealing tube, above the column case isolates the shaft from the pumped liquid.

THE "NO-SEAL" CONVERSION CAN BE ENGINEERED TO ANY MAKE OF VERTICAL TURBINE PUMP

Features
- All bearings and parts are lubricated by the fluid being pumped, eliminating the need for any external lubricants or possible contamination of the fluid.
- For use with either vertical hollow shaft or vertical solid shaft motors.
- Eliminates conventional leaking packing box or mechanical seal.
- Requires no field adjustment or maintenance.
- For installation where suction is vented to the atmosphere.
- Handles volatile and caustic liquids safely.
