The PMT series consists of manually operated pumps with single delivery with displacements from 6 to 45 cm3/cycle. The cycle of PMT pumps is double pumping: the pump generates pressure in both pumping movements downwards and upwards and displacement is therefore to be calculated as the sum of these two movements. Integrated with the PMT pump are a 4-way and 3-position flow diverter, also with manual control, and a double piloted block valve, which make the pumps suitable for feeding a double-acting cylinder. The availability of an optional component such as the integrated maximum pressure valve allows obtaining a complete hydraulic circuit for controlling the actuators, simplifying the installation operations of the plant with savings in terms of time and components.
