When the maximum working pressure of this equipment were 0.6mpa, 1.0mpa, 1.6 mpa, firefighting water storage volume greater than 150L, ??300L, 450L, regulated water volume greater than 50L, for the fire hydrant system, water gun flow per share of 2.5L / S , 5L / S, enrich the water column length 7M, 10M, 13M; when used in automatic sprinkler systems, each nozzle flow 1.0L / S, nozzle pressure 0.1MPA. The device allows the most negative point of fire water piping system remains firefighting pressure, pressure tank and use within 30 seconds there is always fire water reservoir; the operating pressure of the device is the use of the set pressure tank, control pump operating conditions, reach booster regulator function.

Pump axial force borne by the balance drum and angular ball bearings, seal with packing two and machinery. Inlet and outlet flanges are free to choose the direction of the pump in a horizontal range of 360 degrees, put the user at the time of ordering instructions. Main features 1. Compact structure, small size, appearance, decided to install its vertical structure, small footprint, and its center of gravity coincides with the pump foot center, thereby enhancing the smooth operation of the pump and life. 2. The pump inlet and outlet pipes are horizontally simplifies connections. 3. If necessary, the inlet and outlet may be mounted in the same direction or 90 °, 180 °, 270 ° several different directions to meet different connection situations. 4. pumps are rated speed 1450r / min. [Working conditions] 1. suction pressure ≤0.2MPa, or maximum working pressure pump system ≤1.6MPa, ie pump suction pressure + pump head ≤1.6MPa, pump static test pressure is 2.5MPa, please specify when ordering system work pressure . When the pressure exceeds the rated value, in order to withstand the mechanical seal manufacturing uses. Pump and flow part and coupling part with steel materials. 2. Use the media should be water or other liquids similar to water. [Applications] KQDL series vertical multistage centrifugal pump is suitable for urban high-rise building water supply, fire, pressurization, long-distance water, heating, bathroom, heating, boiler heating and water circulation booster, air conditioning and refrigeration equipment and water supply equipment and other occasions. 1. KQDL type for cold water pumps can be used for high-rise water supply, fire booster, the medium temperature not exceeding 80 degrees Celsius. 2. KQDLR model for water heat pumps can be used for heating, heating, hot water circulation booster, boiler HVAC, hotels, restaurants, bathrooms and hot water supply pipe pressurized. Medium temperature should not exceed 120 degrees Celsius. Sales Tel 18,920,273,167 18,663,637,297
