The Kenrich "GP"

The Kenrich "GP" series are designed to pump most types of water based cementitious grouts.
Five different models are available. These pumps are ideal for
grouting metal door frames in place as well as filling hollow block walls,
under machine bed plates, ground stabilization and general void filling.
These pumps are 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.
