The HH200C21 remote water supply pump set adopts an integrated design, with functions such as vacuum self suction, self pressurization, and water hose laying. The entire pump set is composed of a suction booster pump station and a water hose radiation trailer, with a compact structure, powerful functions, and economic applicability. The remote water supply pump unit adopts a low center of gravity double torsion shaft structure, with a large chassis load capacity and strong self balancing ability. It can achieve rapid maneuverability and strong emergency assault ability under the traction of vehicles. The whole machine is powered by a diesel engine, and the vacuum assisted self suction centrifugal pump is directly connected to the diesel engine through a highly flexible rubber transmission coupling, with high transmission efficiency and stable and reliable operation.
