The RAASM 5:1 Ratio drum pump is designed for transferring medium to higher viscosity fluids over distances of 60m or more.

What does 5 to 1 pump ratio mean?

If a pump has a ratio of 5:1, it means that the effective area of the motor piston is 5 times the effective area of the piston pump. Therefore, applying a certain amount of pressure to the motor would yield a fluid output pressure that is five times higher. For example, if a pressure of 100 psi is applied to the motor, it would yield a fluid output pressure of 500 psi when the fluid output is closed.
