Häny HRW 800 agitator

Häny HRW 800 is a stirrer (agitator) with a usable volume of 800 litres, used as a buffer tank between the mixer and the grout pump. The stirrer ensures continuous operation by keeping the ready-mixed suspension moving: a slowly rotating paddle homogenises the grout and removes air bubbles, so that the pump always receives an even and stable mix.

The stirrer shaft is mounted at an angle in the tank with a mixing paddle, which gives full circulation of the entire tank contents without static paddles that are difficult to clean. The tank has a cleaning opening with a safety switch and a central lifting point that makes transport easy. The inlet and outlet connections are 2½", and the maximum liquid temperature is 40 °C.

The motor is 0.55 kW at 50 Hz (0.66 kW at 60 Hz) for 3x 400/460 V, and the paddle rotates at 46.7 revolutions per minute at 50 Hz. It weighs approx. 233 kg and measures 1 232 x 1 144 x 1 666 mm (L x W x H). Options include level sensors 1" (“full – empty”) for demand-controlled and fully automatic operation, and a flange connection with butterfly valve 2½".
