Pemo pumps for ceramics are growing in interest among customers thanks to the interesting technological innovations introduced over the years. Listening to customer’s feedback, Perissinotto has finalized a specific line of ceramic pumps with unique features, innovative technologies and special wear-resistant alloys of the latest generation.
Perissinotto’s main objective has always been to improve the high-pressure transfer system of the slip to the atomizer, with the aim of optimizing the efficiency of the entire production cycle and limiting maintenance and energy consumption.
Perissinotto has achieved improved efficiency thanks to the exploitation of a linear flow and pressure distribution, a design that maintains constant particle size and humidity values in the “atomized” powder, allowing the creation of a higher quality ceramic.
Latest generation technologies
Through specific state-of-the-art control panels that integrate advanced software, quality instrumentation and the latest communication methods. For example, you can automatically maintain the pressure value by selecting it immediately on the control keypad. It should also be considered that all customers who are already using Pemo ceramic pumps use pressures ranging from 12 to 20/21 Bar with rated capacities usually higher than the respective data reported by the manufacturer of the sprayers.
In addition, all models of Pemo pumps for ceramics do not need daily checks for conduction, monitored by the various sensors installed on the machines and by instant communication with the atomizers. On the same panel you can view data relating to energy consumption, working hours, and other production statistics with the possibility of storing the data over time and their possible integration with the company infrastructure.

Pemo pumps for ceramics: the advantages
Below we illustrate the advantages already tested in the field by customers of Pemo pumps for ceramics.
Pressure. When switching from a volumetric system to a centrifugal feeding system from the slip to the atomizer, the pressure value used at the start drops by about 2 bar. This is due to the fact that the pressure that is usually read on the expansion tanks of traditional pumps is given by an average of the pulsations generated by the pumping system, while the centrifugal system is linear and the pressure detected and used is the real one.
Quality of the spray-dried product. It has been shown that the final product (atomized) at relatively low pressures does not change, on the contrary, with the Pemo centrifugal system the particle size and humidity parameters are much more stable and controllable over time, again thanks to the linear distribution of pressure.
Filter group. In the various atomizers served by Pemo pumps, the filter group downstream of the pump has been eliminated. For this, it is necessary for the systems to use an additional sieve before reaching the pump’s service tank. In this way, the centrifugal system does not release particles that could clog the nozzles, even in the presence of any solid residues of congealed slip. By going through 3 stages of operating speed, our technicians have ascertained that, in this way, the residues are totally crushed.
Usury. During testing, it is important to determine the optimal working value with the right ratio between pressure and quality, making the most of the thermal power of the atomizer. A relatively low pressure makes it possible to significantly limit the wear of pipes, valves, nozzles and all the parts crossed by the slip, as well as the pump parts.
Power consumption. Pemo pumps for ceramics allow quality processing at relatively low pressures (15-19 bar) and large flow rates, making them very convenient compared to traditional positive displacement pumps.
Extended maintenance times
Maintenance. From the data collected on the various machines in operation for several years, it appears that the flow rate of the slip is less relevant than the two main factors, the value determined by the operating pressure and the abrasion pressure of the pumped product, which together determine the wear coefficient. Customers have found that the first maintenance is carried out after an average of 6000 to 8000 hours of work.
It was even found that on an atomizer that works at 13 bar with 24-26 tons of capacity, the first maintenance was carried out at 24,500 hours of work, after about 4 years. And, in any case, the many customers who work on pressures between 14 and 16 bar, have longer maintenance intervals with significantly lower maintenance and energy costs.
Bulk. The footprint for positioning in the layout of a normal atomization plant is decidedly smaller than systems with a plunger piston system. And, for what was said before, regardless of the size of the atomizer, the customer needs only one machine to feed the entire system.
Field tests have shown that by working on the distribution of the slip inside the atomizer (in the nozzles, nuts, diffusers, piping between the pump and oxbows of adequate size) of any size with a relatively low pressure, between 15 and 18 bar, the comparison of energy consumption with traditional machines becomes decidedly favorable to the centrifugal system.
If, then, this is possible thanks to the use of a single pump per atomizer, without daily maintenance and a water consumption of 2 to 5 liters for the flushing of the seals, the total general cost of ownership is clearly favorable to the Pemo pumps for ceramics.
Ultimately, each pump model allows a wide range of work by feeding atomizers of any size with a single machine, unlike volumetric systems which, as the flow rate or ATM size increases, the number of pumps installed must necessarily increase.
