Demand-Style Pump: Better suited for longer duty cycles. Include a built-in pressure switch to automatically start and stop the pump at specific pressure settings as flow is needed.

Bypass-Style Pump Better for applications that would cause frequent starting and stopping of a demand-style pump. Continue to run regardless of the pressure in the system, but internally bypass flow if the discharge valve is closed.
