External Impeller Adjustment

• Impeller to suction wear plate clearance can easily be reset by external adjustment in order to maintain hydraulic performance. This delivers long time energy savings, while keeping downtime to a minimum.
• With the application of an adjusting nut/jack-screw mechanism at the bearing cartridge area, axial movement of the impeller can be made upto 5 mm, thereby optimizing the above mentioned impeller to suction wear plate clearance and maintaining pump performance and maximising impeller wear life.

Heavy Duty Shaft & Bearings : Designed for continuous service under the most severe of operating conditions – with low deflection at maximum load – for longer seal and bearing life and optimum performance. 11 pump sizes with 3 frames fitted with spherical roller bearing at the drive end and single row angularcontact ball bearing at the pump end.

Renewable Wear Parts : Lower maintenance costs achieved due to replaceable critical wear parts such as the suction and stuffing box cover wear plates, impeller, and shaft sleeve
