Below are some of its features:

gusher-7071-features

1. Heavy Duty Casings – increases life under corrosive and erosive conditions. All sizes are self venting with CL discharge. Drain plug offered as option.

2. Heavy Duty Shaft – Minimum deflection increases life for less maintenance.

3. Renewable Shaft Sleeve – Hook-type sleeve eases maintenance (easily removed) and is relieved to allow for changes in temperature.

4. Power Frame – Heavy duty Power Frame is sealed against contaminants to ensure long bearing life. Water-cooled for high temperature applications.

5. Oil Lubrication – Oil lubrication is standard. The power frame is vented. Oil may also be cooled for high temperature application.

6. Heavy Duty Thrust Bearing – Double row thrust bearing minimizes shaft end play for more effective stuffing box sealing, longer mechanical seal life and withstands greater axial and radial thrust loads.

7. External Impeller Adjustment – Like new clearance can be maintained through simple external adjustment in just minutes to maintain original high efficiencies.

8. Rabbeted Fits – Accurately machined rabbets ensure positive alignment, longer seal life, easy replacement of spare rotating when maintenance is required.

9. Contained Casing Gasket – Protects against blow out.

10. Positive Sealing at Impeller – Teflon O-Ring protects shaft from liquid being pumped.

11. Semi Open Impeller – is designed with back pump-out vane to minimize axial thrust. Designed to handle solids and stringy material.*

12. Mechanical Seal

13. Seal Gland

*The 3×4-16 and the 5×6-16 have enclosed impellers.
