PCP air pump, also known as a high-pressure air gun pump, is a device used to inflate PCP air guns (Pre-Charged Pneumatic Airguns). PCP air guns use pre-stored high-pressure gas to propel the projectile, so an air pump is needed to inflate the air gun’s air tank.
The working principle of a PCP air pump is similar to that of an ordinary air pump, which uses mechanical force to compress air. However, a PCP air pump needs to compress the air to a very high pressure, usually up to 3000 psi or more, so its structure and material are more complex.
There are two common types of PCP air pumps: single-acting pumps and double-acting pumps.
Single-acting pumps can only inhale a small amount of air at a time, and then compress the air into the air tank through a high-pressure one-way valve. The operation of a single-acting pump is more laborious, and the pump handle needs to be pulled repeatedly to inflate the air gun.
Double-acting pumps can inhale air both when pulling up and pushing down, so they are more efficient. Double-acting pumps usually also have a pressure regulating valve to control the inflation pressure.
