SHURflo internal bypass pumps are the answer to applications where an automatic demand switch is not required. Pumps with bypass will continue to run at high pressure. Ideal for intermittent duty applications. Perfect for transfer applications where smooth consistent flow is needed.

They can be mounted in any position, and are designed for easy maintenance.
