Насос с гидравлическим приводом 84944 и 84961

Hydraulically driven pump 84944 and 84961

For single-line lubrication systems

The 84944 and 84961 are pump systems designed for use with centralized lubrication systems that utilize single-line, parallel components for dispensing grease. The double-acting pump delivers lubricant on both forward and reverse strokes. These units are designed for off-highway applications that utilize 24 VDC power sources. These pumps can be used in conjunction with the following equipment: Cycle Counters 244270 (non-sealed) or 249605 (sealed).

The 84944 hydraulically driven pump features a 60-pound metal reservoir and a release valve (main pump). The 84961 main pump is similar to the 84944 but does not include a reservoir or release valve. These units include a pump and hydraulic regulator.
