Seal (seal): pump seal types are packing seal, expeller seal and mechanical seal. Transmission: there is a V-belt drive, elastic coupling transmission, gear box drive, fluid coupling drive, variable frequency drives, SCR speed and so on. V-belt drive which has CL, CV, CR, ZL, ZV, ZR drive. Overall performance: wide performance range of the pump cavitation performance, high efficiency. Tandem technology can be used to meet the long-distance transport. There are a variety of metal wetted parts are available, and increased depth. Using a variety of speeds and multiple variants ways 300ZJ-I-A90 slurry pump, causing the pump to operate at optimum mining. Long life, high efficiency 300ZJ-I-A85 slurry pump, to meet the multi-class poor transport conditions. Differential shaft power and effective power of 300ZJ-I-A95 slurry pump is the pump slurry pump power loss, its size is determined by the efficiency of the pump to calculate the efficiency of the pump is effective power and shaft power ratio, ie η = Ne / NZ (1-8) by the formula (1-7) (1-8) of the pump shaft power can be obtained for: Ne = QH Sm / 102η KW (1-9) slurry pumps, 300ZJ-I-A90 slag pump, mechanical seal impeller (Certified Merchant) Ltd provided by Shijiazhuang-school Pump.
