Airplaco’s PumpMaster grout pump is used for masonry block fill. The PumpMaster PG-25, known as P-Rock, was developed after refining the PumpMaster model PG-21 grout pump. The new model includes even more features for masonry block fill. The PG-25 includes a three-inch discharge assembly, which has been refined for the use of pea rock in the grout mix. It also features a 25-HP Kohler engine to give the machine the needed power for pumping over longer distances on the jobsite. The pump fills block without the need of a forklift or full-size concrete pump.
