Selecting the Right Pump
Bypass Pumps continue to run regardless of pressure in the system by internally bypassing flow if the discharge outlet is closed. The motor and pump stay running and are ready to deliver full power as soon as the system outlets are re-opened. However, if the system outlets are closed for extended periods of time overheating can occur.
Eliminates pump cycling and provides instant flow when needed.
Perfectly suited for variable demands in a single system.
Spray bars, multiple outlet systems, whenever different flow rates are needed in one system.
Demand Pumps include a built-in pressure switch to automatically stop and start the pump at specific pressure settings. These pumps only run when discharge outlets are open and fluid delivery is needed. However, ON/OFF cycling at extreme frequency can cause damage to the pump components.
Pump only runs when flow is needed and offers reduced noise during system idle. Automatically turns pump off when not in use.
Spot spraying, soft wash, single outlet systems.
Bypass-Demand Pumps combine all the advantages of the bypass and demand pump styles. The pump heads have a pressure sensing switch AND an internal bypass valve. These pumps can adapt to changing system demands to deliver consistent flow regardless of which discharge outlets are open. Once all system outlets are closed the pressure switch will activate to turn off the pump. Bypass-Demand gives you consistent flow on demand and eliminates pump cycling with any outlet system configuration.
Pressure Sensing On/Off switch, perfect for handling multiple output demands in one system. Eliminates pump cycling, and provides Instant flow when needed. Works well with varying flow rates
