Fully open impeller, best design for the chemical process industries services. Ideally suited for corrosives and abrasives, handles solids and stringy fibers with ease. Allows for simple restoration of clearances when wear takes place. Back pump-out vanes reduce pressure on the shaft seal, reduce axial thrust on the bearings.

Materials for Impellers
Impellers are available in various materials to suit different conditions:
• Hard iron: common for abrasive mud/oilfield use.
• High chrome: high abrasion resistance.
• Stainless steel: ideal for corrosive chemicals, acids, or environments where rust/chemical attack is a concern.
• Others: Aluminum bronze, Tungsten carbide coating.

Centrifugal Mud Pump Design Feature:

• Wider impellers and increased re-circulation areas. Each feature,contributes to reducing wear when handling abrasive fluids.
• Concentric casing that is an average of 37% thicker than conventional pump casings, The concentric style casing has proven to offer the greatest pump life and reduced downtime.
• The shaft is much larger in diameter than conventional pump shafts for heavy-duty performance, minimum deflection and increased operating life of the seal or packing.
• An easily removable stuffing box allows these pumps to be customized to meet customer needs.
• Magnachrome impellers have a 400 Brinell hardness and Magnachrome casings and stuffing boxes feature a 600 Brinell hardness.
