Video: High Pressure Plunger Pumps With New Drive Technology
The better is the enemy of the good: According to this principle, Kamat has developed a new drive train for high-pressure plunger pumps and has successively introduced these drives in all series. The reason was the request of some users, for example in the mining industry, for low-noise high-pressure pumps. This requirement was difficult to meet with the proven drive concept of the Kamat pumps because the crankshaft - which moves the plungers via crossheads - had to be asymmetrical in order to be able to fit them into the previously undivided housing. The asymmetry results in stronger vibrations, which made it difficult to decouple sound via damping elements due to the vibrations.
Newly designed double helical teeth
The Kamat designers then developed a split housing in which a symmetrical, balanced crankshaft takes over the power transmission between the drive and the plunger. A newly designed double helical toothing also contributes to increased smoothness and reduced noise emissions from the pumps. The gearboxes come from our own production, since Kamat had already taken over the then supplier of drive components in 1983 and has had the relevant know-how in-house ever since.
The new design is now used in the triplex pumps in the power classes from 80 to 800 kW. It is also the basic drive design for the Quintuplex pumps, which Kamat has developed to series production and which, from the user's point of view, enables considerable cost savings with large volume flows.
In addition, the mechanical part of the drive creates the prerequisites for a needs-based variable-speed control of the pumps, which is one of Kamat's core competencies and enables energy-saving, needs-based operation of the plunger pumps. (jv)
