Kalvopumpussa

Kalvopumpussa is a type of positive displacement pump that utilizes a flexible diaphragm to move fluid. This diaphragm acts as a barrier between the pumping chamber and the drive mechanism. As the diaphragm moves, it creates a change in volume within the chamber, drawing fluid in during the suction stroke and expelling it during the discharge stroke.

The movement of the diaphragm is typically driven by a mechanical linkage connected to a rotating shaft, a solenoid, or a pneumatic actuator. Mechanical pumps often use a connecting rod and crank mechanism, while solenoid-driven pumps use an electromagnet to oscillate the diaphragm. Pneumatic pumps rely on compressed air to push and pull the diaphragm.

Kalvopumpussa are known for their ability to handle a wide range of fluids, including corrosive, abrasive, and shear-sensitive materials. The absence of seals in contact with the fluid minimizes wear and leakage, making them suitable for applications where contamination is a concern. They can also operate dry without sustaining damage, a feature not common in many other pump types.

These pumps are commonly found in various industries, including chemical processing, water treatment, pharmaceuticals, and food and beverage manufacturing. Their applications include metering, dosing, transferring, and sampling of liquids. The relatively simple design and robust construction contribute to their reliability and low maintenance requirements.
