Description

Piston pumps struggle with thick cement mixes, while this pump moves them smoothly. It comes with motor, gearbox, feeding assembly, worm gear, stator, pressure gauge, hopper and electric control system. Pressure builds up evenly inside the chamber for steady pumping, and the pressure reverse function quickly releases residual injection pressure.

Features

1. Compact body with imported electric parts, fewer breakdowns during long shifts of construction
2. Easy to run; daily maintenance only needs simple cleaning work
3. Light weight with wheels, workers can move it between construction spots effortlessly
4. Works with mixes that have high water-cement ratios to form dense filling layers
5. Pumps grout with high sand content and different sand sizes without clogging
6. No sudden pressure spikes. Operators can adjust pressure freely and reverse pressure to release excess pressure fast
