Pneumatic
systems make use of pressurized gases to move media and in industrial
applications, they are typically powered by compressed inert gases. A
compressor located at the center is used to power motors, cylinders,
and other pneumatic equipment, including Pneumatic pumps. These
systems are often regulated through either a manual or automatic
solenoid valve and can offer a more flexible, safer, and low-cost
alternative to electric and gas-powered motors.
Different
Types of Pneumatic Pumps
Pneumatic
pumps are typically double-acting positive displacement pumps with no
return spring and can use many pressurized gases as their drivers.
There are a number of pneumatic pump options, but some of the
commonly known options include:
- Pneumatic Liquid Pumps – These are specially designed pumps used to move liquid.
- Pneumatic Diaphragm Pumps (both piston and plunger types) – They utilize a plunger or piston mechanism to transfer media via a cylindrical chamber. This mechanism is driven by a pneumatic, hydraulic, electric, or steam drive.
- Pneumatic Test Pumps – These pumps are designed and set up to test the potency of a particular pneumatic system.
- Pneumatic Refrigerant Pumps – These pumps have usually two stages which are used to move the refrigerant.
Applications
Pneumatics
pumps are particularly designed for challenging oil and gas
production uses, along with that, their use in common in many other
industries such as fertilizer dosing, pulp and paper, water
treatment, and food processing.
Pneumatic
diaphragm pumps are able to handle many different types of fluids,
even those that incorporate some solid material. The design of these
pumps provides security against piston corrosion and decreases the
risk of seal related problems.
