High Chrome Slurry Pump Impellers

Jul 21, 2020

Slurry Pump Impeller is the main component in centrifugal slurry pumps which has vanes to impart and direct the centrifugal force to the slurry.

Slurry pump impeller is also the most diverse component in slurry pumps, by changing impeller, the same slurry pump can cover more different duties.

Slurry pump impellers are normally made in high chromium alloys or natural rubber, special materials are also available.

Tobee manages a complete inventory of slurry pump impellers which are dimensionally interchangeable with all other brand slurry pumps.

High Chrome Slurry Pump Impeller Materials:

Code

Hardness 
HRC

Performance

Application

A05

≥56

Ranks second only to A07 in abrasion-resistant performance; fair corrosion-resistant performance.

High impact load abrasion condition; PH rate ranging from 5 to 12

A07

≥59

Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05

High impact load abrasion condition

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

≥62

Higher abrasion-resistant performance than A05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where A05 is not suitable.

High abrasive slurry with fine particles.

A61

63-68

Optimized abrasion-resistant performance than A12

High abrasive slurry with fine particles.


Rubber Slurry Pump Impeller Materials:

MaterialCodeApplications
Natural RubberR08R08 is low to medium hardness rubber used for impellers where slurry contains fine particles and erosive.
Natural Rubber(soft)R26R26 is soft natural rubber used for liners where slurry contains fine particle and more erosive.
Natural Rubber(soft)R33R33 is widely used for frame plate liners, cover plate liners and impellers. Maximal particle diameter is 10mm; impeller peripheral speed should be less than 25m/s; suitable for temperature not exceeding 75°C.
Natural RubberR55R55 is widely used for impellers, frame plate liners, cover plate liners and throat bushes. Maximal particle diameter can be 20mm, impeller peripheral speed should be less than 27.5m/s; suitable for temperature not exceeding 75°C.
EPDM RubberS01S01 is widely used for impellers, frame plate liners, cover plate liners and throat bushes. Maximal particle diameter can be 8mm; impeller peripheral speed should be less than 25m/s; suitable for temperature not exceeding 120°C(continuous duty) or 140°C(discontinuous duty).
Nitrile Rubber(NBR)S12S12 is widely used for frame plate liners, cover plate liners, throat bushes, lip seals, impellers and expellers. Maximal particle diameter is 7mm; impeller peripheral speed should be less than 27m/s; suitable for temperature not exceeding 95°C.
Butyl RubberS21S21 is widely used for impellers, frame plate liners, cover plate liners, expellers, volute seals and throat bushes,. Maximal particle diameter can be 7mm; impeller peripheral speed should be less than 30m/s; suitable for temperature not exceeding 100°C.
HypalonS31S31 can be used for impellers, frame plate liners, cover plate liners and throat bushes,. It is recommended to use for strong acid slurry with mild or moderate corrosion. Maximal particle diameter can be 10mm; impeller peripheral speed should be less than 30m/s; suitable for temperature not exceeding 110°C.
