PFT G4 is a continuously operating mixing pump (otherwise known as plastering machines or mortar pumps) for machine-use suitable, ready-mixed, dry mortars, gypsum and lime. It can be filled using bagged cargo as well as directly from a silo / container using a delivery hood or with an injection hood and the PFT SILOMAT systems.

PFT G4 is a compact, easy to transport mixing pump which offers a high delivery rate and large delivery range, and can be combined with the entire range of machines offered by PFT. The low filling height makes it perfectly suited for filling with bagged cargo and is ideal for use at small and average sized construction sites. The material hopped is separate from the mixing and pumping unit, and can operate both continuously and fully automatically, allowing it to be refilled and started back up whenever you need. 

With flexibility of use, the G 4 provides a perfect individualised solution for a vast range of job types.
