The Kenrich “GP” series are designed to pump most types of water based cementitious grouts (typically not used to pump chemical based epoxy grouts). These pumps are ideal for grouting metal door frames in place as well as filling hollow concrete block walls, under machine bed plates, ground stabilization and general void filling. This series is ideal for placing grout anywhere that high pressure is not required. They are small and lightweight which allows the user to take the pump to where the grout is needed.
