Häny ZMP 610 pump

Häny ZMP 610 is a very compact and wear-resistant piston pump (plunger pump) for grouting. It is designed for pumping suspensions with a low water/cement ratio and mortar containing sand, and is suitable for all grouting work as well as pumping backfill mortar behind segmental linings in tunnels.

The pump is built as a vertical grout pump with a single pump module and takes up little space when installed. Grouting pressure and delivery rate can be limited steplessly, and a fast suction stroke flushes the valves so that clogging is avoided. The wear parts are easily accessible, which gives high reliability and low maintenance. The cooling water connection makes continuous operation possible even at high ambient temperatures.

The ZMP 610 has a plunger diameter of 65 mm, a capacity of up to 1.5 m³/h (w/c = 1) and a maximum pressure of 100 bar. The largest particle size is 5 mm. The control system is PLC-based with lockable main switch, emergency stop and pump on/off. Manual pressure and flow control plus indicators for oil level, temperature and filter contamination are standard, while remote control and data logging of pressure and flow are options. The motor delivers 5.5 kW at 50 Hz for 3x 400/460 V, and the weight is approx. 270 kg.

Typical applications are grouting of anchors, soil nails and prestressing tendons, sleeve-pipe, rock and contact grouting, pre-grouting and post-grouting, pumping of bentonite suspensions for pipe jacking and microtunnelling, and pea gravel filling.
