Diaphragm Metering Pumps

Jaeco Series E Electronically Pulsed Diaphragm Metering Pumps (3 to 500 GPD)

Features/Benefits

• For low-flow applications where flexibility, accuracy, compact design and economy are important.
• Stroke length is manually adjustable for a turn-down ratio of 10:1.
• Stroke rate is manually adjustable for a turn-down ratio of 10:1.
• Stroke can be controlled automatically on some models.
• Single ball check valve, standard on both suction and discharge side of the pump, provides accurate metering and fast response. Valve ball turns with fluid flow, constantly presenting a new face to the seat, and is therefore self-cleaning.
