d. the pump is running when you close the outlet valve is called the closing pressure operation state, all-plastic or plastic-lined pumps pump pressure off the running time should be shortened as much as possible, at room temperature to no more than 5 minutes the media is limited, the best high temperature medium Do not exceed 2 minutes;. e in case of pump cylinder 32UHB-ZK-5-20, such as import 150mm or more pumps, sealed plastic at the equatorial plane, due to thermal expansion and contraction size of some changes, the installation should be carved at the attachment bolts tightened, and then connect the import pipeline, to prevent leakage to the equatorial plane 40UHB-ZK-10-18, this provision is particularly important for users in the north;. f pump can not support the weight of import and export pipelines, import piping as short as possible, the pump outlet to the vertical height at the valve should be as short as possible;. g holding no water stains on the motor to prevent the motor from moisture. Fourth, the use of: 1) sulfuric acid phosphate fertilizer industry: acid, liquor, sewage, water, fluorine-containing silica acid, phosphoric acid slurry and other transmission medium. 2) non-ferrous metal smelting industry: particularly suitable for lead, zinc, gold, silver, copper, manganese, cobalt, rare earth hydrometallurgy of various acid 32UHB-ZK-5-25, corrosive pulp slurry (press filtration machines equipped with) electrolyte, sewage and other media delivery. 40UHB-ZK-10-18,, mortar Pump Co. sent by Shijiazhuang-pump.
