Pumps

The Pump is the part of the compressor responsible for compressing air. It is arguably the most critical component of your air compressor. Without a Pump, air remains at atmospheric pressure.

Pumps For Industrial Air Compressors

Air pumps are a representation of your air compressor’s heart. The pump is crucial for the air compressor to do its job. Without a pump in place, the air won’t be put under pressure. Having a reliable pump in place ensures smooth and uninterrupted operations, minimizes downtime, and reduces maintenance costs.

The majority of compressors have preset pressure limits. When you power yours on, it will keep working until it meets the required demand. When you use your compressed air, the motor will automatically reengage to continue the process.

When the motor comes on, a moving piston creates a vacuum inside the machine. The suction opens an inlet valve that draws atmospheric air into the area above the piston head. When the piston comes up, it compresses the air, sealing the inlet valve closed. When it goes down, the pressure engages the discharge valve, and air enters the tank.

Different Pumps For Different Operations 

The pump is often the primary differentiator when it comes to different compressors. Depending on how much compressed air your operation requires, the pump model can change per application. 

Reciprocating Air Pump

Reciprocating air pumps will be the most common type of pump because the reciprocating compressor is the most common compressor. They are known for their robust construction and durability. With a longstanding design, they can quickly be overhauled and repaired to further extend their lifespan. 

With a piston driving the crankshaft, these repeated motions compress ambient air until it reaches the desired pressure. As the crankshaft turns, the piston moves up, reducing the volume of the compression chamber. Once it has reached a full extension, the air is released to the next step or stage, and the piston moves back down to pull in more air. 

Pumps can be relatively expensive to purchase and operate. They require regular maintenance, including lubrication and replacement of valves and seals. Compared to other compressor pumps, they generate more noise and vibration.

Rotary Screw Air Pump

Another prevalent type of compressor pump is the rotary screw air pump. These machines use a male and a female rotor to compress the air continuously. They are known for their continuous operation and high efficiency during compression. Unlike piston compressors, which need to close and open the chamber to reset for the next round of compression. 

On the other hand, the interlocking nature of these rotors allows air to simultaneously be compressed to the highest pressure and pull in ambient air to compress. These pumps excel in applications that require a constant and steady supply of compressed air, such as manufacturing, automotive, and food and beverage.

Continuous operation comes at a steeper upfront cost than reciprocating compressors. This may seem steep, but these pumps compress twice as much air in comparison, if not more. You are investing in high-quality, reliable, compressed air.

 

Pumps vs. Compressors

A common misconception is that pumps and compressors are the exact same thing. They are very similar but not identical. Air pumps are typically a single component of your whole air compressor. They work in tandem with aftercoolers, storage tanks, and filtration to output high-quality compressed air. 

 

They may look similar, especially from the outside. Don’t let the similarities fool you. Your compressor is the heart and soul of your operation, but the pump gets the air moving from the compressor. Without the pump, your compressor won’t be able to operate as expected. If your system makes extra noise, creates less air flow, or your electricity bill is skyrocketing, you may need to replace your pump.
