The Walchem EWB10F2-VC pump is obsolete and was replaced by the EWB11F2-VC pump which has a new head and diaphragm design. Both the EWB10F2-VC and the EWB11F2-VC have the same specifications of 0.6 GPH, 150 PSI, digital input, PVC/CE/FKM, 3/8" OD, 230 VAC. Many of the liquid end parts are also interchangeable between the two generations.
