Overview of Sealed Pumps
Sealed pumps are specialized devices designed to move fluids without leakage. They offer distinct advantages in applications requiring containment of hazardous or valuable materials.
Definition and Function
Sealed pumps are fluid-handling devices that prevent leaks and contamination. They use seals or enclosures to isolate the pumped fluid from the environment. These pumps move liquids or gases while maintaining a closed system.
Diaphragm pumps are a common type of sealed pump. They use a flexible membrane to create suction and discharge, keeping the fluid separate from mechanical parts.
Sealed pumps often serve as metering pumps. This allows precise control of fluid flow rates in various industrial processes.
Types of Sealed Pumps
Encapsulated pumps are a key category of sealed pumps. These units have their motor and impeller enclosed in a single housing. This design eliminates shaft seals, reducing leak risks.
Magnetic drive pumps use magnetic coupling to transmit power. The motor sits outside the pump casing, with no direct connection to the impeller. This setup prevents leaks effectively.
Canned motor pumps integrate the motor and pump into one sealed unit. The motor rotor spins in the pumped fluid, eliminating the need for a shaft seal.
Peristaltic pumps use flexible tubing and rollers. The fluid only contacts the inside of the tube, making them ideal for sterile applications.
Oil Sealed Pumps
Oil sealed pumps use oil as a sealant and lubricant to create vacuum conditions. They come in different types suited for various vacuum applications. These pumps offer reliable performance and are widely used in industrial and scientific settings.
Oil Sealed Rotary Vane Pumps
Oil sealed rotary vane pumps are common in many industries. They have a rotor with vanes that spin inside an oil-filled chamber. As the rotor turns, it traps air between the vanes and pushes it out.
These pumps can reach medium vacuum levels. They work well for tasks that need steady suction. Labs often use them for filtration and distillation.
The oil helps seal gaps and cool the pump. It also lubricates moving parts. This design makes the pumps durable and long-lasting.
Regular oil changes keep these pumps running smoothly. Dirty oil can harm pump performance. Some models have oil filtration systems built in.
Oil Sealed Vacuum Pumps
Oil sealed vacuum pumps create low-pressure environments. They remove air and gases from closed systems. These pumps are vital in manufacturing, research, and medical fields.
The oil forms a tight seal between moving parts. This seal stops air from leaking back into the vacuum chamber. Oil also helps cool the pump as it runs.
Different sizes of oil sealed vacuum pumps exist. Small ones work for lab equipment. Larger models handle industrial-scale jobs.
Some pumps have special features. Gas ballast valves help remove water vapor. Exhaust filters catch oil mist. These add-ons improve pump efficiency and lifespan.
Oil Sealed Rotary High Vacuum Pumps
Oil sealed rotary high vacuum pumps achieve very low pressures. They are key tools in advanced scientific research and high-tech manufacturing.
These pumps use a multi-stage design. Each stage compresses gases more than the last. This setup lets them reach extremely low pressures.
The oil does more than lubricate in these pumps. It also traps gas molecules, boosting the vacuum level. Special oils with low vapor pressure are often used.
High vacuum pumps need careful maintenance. They’re sensitive to contamination. Many have built-in oil return systems to keep the oil clean.
Some models can reach pressures below 10^-6 mbar. This makes them suitable for tasks like thin film deposition and electron microscopy.
