1 The main technological characteristics
    —Domestic origination, reliable performance, it has the advantage of large aggregate concrete conveying compared with the same type equipment.
— Adopt double flameproof three-phase asynchronous motor, it is good reliability and strong power.
—Constant power variable pump can adjust the output automatically. The energy can be fully used and it can realize long-distance and large opening high pressure pumping.
—The machine has compact structure, convenient for dismantling; facilitate transportation and maintenance.
—The weary parts are super anti-weary. The super anti-weary glass plates and cutting rings made of hard alloy greatly prolonged the service life the weary parts. cutting ring with self-compensating wear-resisting ring.
—Hydraulic system is hydraulic controlled directional control, low impulsion.
—It adopts independent water cooling system, cooling effect is good.
—HBMD-90/16-180S High-output operation and high-pressure operation working mode
