Walchem EK Series Diaphragm Metering Pump (EK)

The Walchem EK series pump is now obsolete and the closest available series is the EWN-R pump. For reference, the obsolete EK specifications were:

• Diaphragm Pump
• Max Output: 0.6 GPH - 6.7 GPH
• Max Pressure: 30 - 150 PSI
• Manual or external digital control

However, the obsolete series was IP67 rated and the new EWN series is only IP65 rated.
