Gear pumps are a type of rotary pump that works on the principle of displacement. They have a simple structure and are easy to operate. The MT 136 kit is part of the GUNT Practice Line, which is designed especially for training in vocational schools and company training centres. The relationship between theory and practice is very close. Assembly and disassembly are simple and can be carried out with basic tools included in the package. In addition, the gear pump seats are designed so that the entire process can be done manually.
