Tobee® Slurry pump impeller H18137DPT2A05 is one of the most important parts of centrifugal slurry pumps. Depending on the application, Slurry pump impeller selection can be crucial to slurry pump performance. Slurry applications can be especially hard on the impeller of your slurry pump because of their abrasive nature.
20/18 AH Slurry Pump Design features and benefits：
• Heavy duty construction with through-bolt design provides ease of maintenance and minimal downtime
• Ductile iron fully lined casing provides durability, strength, safety, and long service life
• Large diameter, slow turning, high efficiency impellers designed to achieve maximum wear life and low operating costs
• Large, open internal passages designed to reduce internal velocities, maximize wear life and lower operating costs
• Thick elastomer or alloy bolt-in liners provide superior corrosion resistance plus offer ease of liner change-out and interchangeability to reduce overall maintenance costs and maximize wear life
• Minimal shaft/impeller overhang reduces shaft deflection and increases packing life
• Cartridge-style bearing assembly allows for maintenance in a clean environment without removal of the pump, resulting in reliable operation and prolonged bearing life
• Grease or oil lubrication bearing assembly options offer ease of maintenance and reduced downtime
• Optional dry running shaft seal reduces or eliminates flush water requirements
• Effective expeller prolongs packing life while reducing or eliminating flush water requirement
• Now featuring WRT1 throat bush and impeller combination designed to enhance efficiency and improve wear performance
• Interchangeability of seal arrangements – full flush, low flow, centrifugal, or mechanical seals may be fitted to any sized pump

A33 |
≥35 |
Abrasion-resistant performance is close to A03; fair corrosion-resistant performance |
Oxide slurry with PH rate no less than 1, like phosphor-gypsum in phosphate fertilizer plant, nitric acid, sulph-oacid and phosphoric acid, etc. |
|
A49 |
≥43 |
Fair abrasion-resistant performance, close to A03; fair corrosion-resistant performance in media with lower PH rate. |
Corrosion conditions with low PH rate, especially for flue gas and FGD devices for media of PH≥4; general suitable for lower acid condition. |
|
A12 |
