Advantages
1. EHM and EGM series product belongs to heavy duty slurry pump, which adopts thick materials and high chromium alloyed materials of main wear parts, featuring excellent abrasion resistance. Even if working in high abrasive condition, our product still maintains long service life and high performance to price ratio.
2. Besides, with the structure of double casing, our heavy duty slurry pump is easy to disassemble and replace the spare parts with low cost of maintenance.
3. Compared to foreign product in AH and HH of Warman series, our product possesses higher performance to price ratio.
Note
1. This heavy duty slurry pump utilizes three seal types, including packing seal, expeller seal and mechanical seal. If there is no requirement, we normally choose the expeller seal. Otherwise, users should tell us their demands before placing the order.
2. Pump discharge direction is designed to rotating installation according to eight angles. Generally, the discharge is settled upside, or customers can give their requirement according to the specific conditions before purchasing.
3. The drive type of our product falls into direct connection, V-belt drive, gearbox transmission, fluid coupling drive, variable frequency drive and so on.
