HRA Integral Gear Reducer Parts for 3 inch Blackmer GX Series Pumps

NOTE: Models GX2B and GX2.5B are no longer available. PUMP END parts will be available for 5 years. The GX2B and GX2.5B GEAR REDUCTION UNITS are no longer available, and parts for them will be obsoleted as inventory is depleted. Blackmer GNX(H) models have replaced the GX series. Please see the informational link on the 'Blackmer Motor Driven Pumps' page of our web store for GNX(H) models.

GX3E and GX4B models will be obsoleted around the 3rd quarter of 2018 and replaced by their own GNX(H) models. Plans for parts support are the same as for the 2" and 2-1/2" models noted above.
