Walchem EWN-R Metering Pump, 14.4 GPD, 150 PSI, EWN-B11VFURM
Description
- Highly versatile—control using analog or pulse inputs
- Multifunction valve offers anti-siphoning, backpressure, air vent/bleed and pressure relief
- For use with fluoride
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. Normally open/normally closed output relay is programmable for STOP or SPM—use it to control an alarm or switch to a second pump.
Use with fluoride and hydrofluosilicic acid. Call for compatibility with other chemicals.
Wetted materials: PVC head, PVC fittings, PTFE check balls, PTFE diaphragm and EPDM seals.
