TV2g
Construction Features
1. The JM shaft motor, which is standard on the Thrush TV2g close coupled in-line pump, is the result of a joint  NEMA-Hydraulic Institute Standard on motors to be used on close coupled pumps. The JM shaft motors are more readily available, give quieter operation and longer seal life.

2. Long-life mechanical seal is supplied with EPT elastomers, 303 stainless steel metal parts, carbon rotating washer, and Ni-Resist stationary seat. It is pre-assembled on a bronze shaft sleeve (cartridge seal assembly) to ensure correct mechanical seal positioning and easy servicing.

3. Shaft wear and corrosion are prevented by a slip-fitted pinlocked, bronze shaft sleeve seal assembly extending through the seal box.

4. Elastomer gaskets seal both the shaft sleeve and impeller capscrew to prevent shaft corrosion and isolate shaft from pumped liquid.

5. Improved bracket design incorporates a diverging seal chamber that creates a vortex action to stimulate seal chamber circulation. This eliminates air and foreign particle build-up and carries off frictional heat from seal faces. An internal flush line increases recirculation in seal chamber, provides manual venting, and, if required, can be adapted to an external flush line. This design eliminates the need for strainers, filters, or cyclone separators, since the pumping action does the job.

6. Back pullout design allows for maintenance work without disturbing piping.

7. Impellers are hydraulically and dynamically balanced and designed at maximum diameters of 85% of cut water radius to insure quiet and efficient operation.

8. Improved casing designed for hydraulically quiet performance and for 125 pound ASA drilling.

9. Suction and discharge gauge tappings located for ease of access.

10. Adequate drain and vent tappings. .
