Mobile unit specially designed for its use with hard to pump sticky and high viscosity greases (up to NLGI3). The pump’s lower end is fixed to an inductor plate and the pump is mounted to a pneumatic piston that elevates the pump for replacing an empty pail. The pneumatic piston also acts when the pump is in use, pushing the inductor plate against the grease, aiding the pump prime, making possible to pump very high viscosity grease. The unit includes a PM35 - 60:1 pressure ratio pump and it is mounted to a rolling base with 4 wheels, two of them with brake. Instruction book: 842808.
