A pump is a mechanical device that transfers mechanical energy to a fluid, increasing its pressure and enabling it to move to a higher elevation (by increasing head) or even to a downstream location (typically a basin or tank).
A mono pump is a type of positive displacement pump, also known as an “eccentric screw pump” or “progressive cavity pump.”
The mono pump was invented in the 1930s by René Moineau. It consists of a rotor (a rotating metal screw) with a coarse pitch and deep threads and a narrow core. The pitch of the rotor is half the pitch of the stator.
The rotor rotates inside the stator, creating cavities that move from the suction side to the discharge side of the pump, which results in transferring the pumped liquid.
The absence of leakage between the screw surfaces of the rotor and stator ensures a constant flow rate proportional to the rotational speed of the pump.
To prevent leakage between stages, a closed cavity must exist—formed by two sections of the rotor, each interacting with a section of the stator.
The rotor motion is compound: rotation around its own axis and simultaneous eccentric rotation around the stator axis.
1- **Rotor:**
The rotor (or screw) is the main rotating component of the mono pump and is responsible for pushing the fluid forward. It is usually made of stainless steel. To reduce friction, starting torque, and facilitate rotation, the rotor surface is polished as much as possible.
2- **Stator:**
The stator typically consists of two parts:
– An internal part made of elastomer
– An external metal casing made of steel
Elastomers are usually made of natural or synthetic rubber and plastics such as Teflon, polypropylene, etc.
Mono pumps are ideal for pumping food materials without damaging their texture.
They offer precise control of output volume through pump speed control, require no frequent replacement of spare parts, are made of Stainless Steel 316L, resist temperatures up to 130°C, and withstand chemical materials such as:
chocolate, cream, cheese, yogurt, tomato paste, concentrates, jam, honey, pulps, sauces, ketchup, gluten, glucose or starch, dough, biscuit and cake batter, kashk, edible gelatin, edible oils, fruit pulps, coffee, tea, liquid glucose, syrup, canned foods, and more.
Mono pumps are used for viscous liquids where maintaining texture is important, such as various sauces, tomato paste, honey, cream cheese, stirred yogurt, strained yogurt, and more.
