Self-priming Pump CBH-80

Описание

Self-priming pump CBH-80 and its units (hereinafter referred to as pumps or units) are designed to pump liquids without mechanical impurities. Pump CBH-80 is designed to pump the following liquids: water, gasoline, kerosene, diesel fuel and other liquids with a viscosity of not more than 2×10-6m2/s at a temperature from -40̊С to +50̊С and a density of not more than 1000 kg/m3. The pumps are available in right (Fig. 2) and left (Fig. 3) rotation. The direction of rotation is determined by the position of the pump output shaft. Before installation, check the scope of delivery of the pump or unit, the integrity of the seals, the presence of plugs on the suction and pressure pipes, turning the wheel shaft pump with force up to 5 N×m. The pump or unit is only supplied assembled and does not require disassembly for installation. Depreservation procedure: pour 2-3 liters into the pump through a funnel with a mesh gasoline and turn the pump shaft several times by hand. Pumps or units for pumping light petroleum products conservation do not produce. Before installation, flush the pump cavity with a 5% solution of baking soda at a temperature of + 50-60̊С for two to three minutes. Pumps for pumping water and food liquids must be depreserved before installation. Rinse for thirty minutes: with one of the solutions (caustic soda 0.8-2% at t = 70-80̊C or nitric or sulfamic acids 0.3-1.5% at t=65-70̊C). Install a mesh filter on the suction pipe 1…1.5 mm. Connect the suction and pressure pipes. vertical section pressure pipeline must be at least 260 mm. Suction pipeline should be airtight and as short as possible.
