• Highly versatile—control using analog or pulse inputs
• Auto degassing valves vent without losing pressure
• 2-year bumper-to-bumper warranty

Economical EWN-R pumps offer the pumping accuracy and advanced control options typically found on more expensive pumps. Dual-ball check valve assemblies in the suction and discharge fittings guarantee reliable performance. Precision ball guides and tapered seats ensure complete ball seating with every stroke for fast priming, accurate feed control and extended diaphragm life. Improved diaphragm design provides leak-free operation.

Pumps offer high-speed operation up to 360 strokes per minute. Their high compression ratio ensures proper feed, especially with off-gassing chemicals like sodium hypochlorite. 1800:1 turndown offers optimal flexibility across a number of applications. Pumps accept pulse inputs or fixed/scalable analog inputs; program via the user-friendly menu. Pulse inputs can be multiplied or divided to work best with your application. NO/NC output relay is programmable for STOP or SPM—use it to control an alarm or switch to a second pump. VCURA models have an auto degassing valve to prevent gas-lock conditions.

Wetted materials: PVC head, PVDF gaskets, ceramic check balls, PTFE diaphragm, and FKM seals.

Pumps include: injection valve, foot valve, ceramic weight and 20' of polyethylene tubing.
