Perissinotto Spa – world leader in the design and manufacture of centrifugal pumps for industrial use – announces the start of distribution of the first four-stage Pemo Pump, serial number 43.000 since 1947, the year the company was founded in Vimodrone (MI, Italy).
The new Pemo four-stage pump is the result of careful listening to the needs of customers who require higher performance, especially in terms of head (ability to push a fluid at a certain height) and durability. The result is the result of careful design work and decades of experience in the production of multi-impeller pumps.
The four-stage Pemo is a multistage centrifugal pump designed to work in high-pressure environments that uses four impellers arranged in series. The four-stage model is particularly effective in contexts where the suction of a fluid under pressure from the bottom to the top is required.
In a four-stage pump, each “body” or “stage” consists of an impeller and a diffuser that work in harmony with the rotational speed and fluid extraction pressure in the subsequent stages. The physical principle of a four-stage pump is based on the centrifugal force generated by the rotation of the impellers in succession. Each impeller “adds energy” to the fluid by converting the motor’s mechanical energy into kinetics. With each pass, the velocity of the liquid increases, pushing it towards the diffuser, where the kinetic energy is “converted” into pressure.
The main advantage of the Pemo four-stage pump is the ability to increase pressure without reducing flow rate. This makes it particularly useful in applications where a constant, pressurized pressure flow needs to be maintained over a long distance or at high depths, such as mining.
The major innovation of the new four-stage pump from Perissinotto is a head (meters of water column) of up to 200 meters. Another distinctive technical feature of the new Pemo pump is the ability to reach a pressure of up to 30 bars.
Thanks to these two features, Perissinotto’s Pemo Pumps four-stage pump is capable of working at reduced speeds and, at the same time, with much longer durations, ensuring high-efficiency operation for long periods and making it ideal for various industrial applications.
