Constructive characteristics:

The triplex pump are single-acting pumps with external toothed cylindrical gear, bilt especially for operating conditions of cementing units.
The pumps are designed to run on reduced revolutions providing proper filling of pump cylinders and more than 0,9 volumetric efficiency on natural suction without supercharging.
The hydraulic part of pump may be equipped, as desired, with the following range of plungers: Ø115; Ø125 mm, according with the maximum working pressure of cementing unit. In hydraulic part of pump mechanical energy is converted to hydraulic energy at the required operating pressure.
The hydraulic body is independent for each cylinder and is fixed to the pump frame.
The discharge chambers at the 3 hydraulic bodies are united by discharge collector.
The suction chambers of the hydraulic bodies are united by a common collector, sealed against each chamber.
