Dual post ram grease pumps

Our Dual Post Ram Grease Pumps include our GDP, G6DP, and GNDP. The ram-style of these pumps allows the utilization of almost all the material in your container, with no pump adjustments. Our standard GDP is perfect for all drums of grease with an NLGI of 00-2, more viscous greases require a G6DP or a GNDP, depending on the size of the grease container.

Features and Benefits

    • Dependable and sturdy due to the extra force capacities provided by two post ram pumps.
    • They pump all the way to the bottom of your container, reducing the volume of wasted grease.
    • These grease sources keep pump suction “off the floor”, to minimize debris in the grease during a container change
    • Various ram options are available for all grease viscosities.

Product details

Dual Post Ram Pumps have been meticulously engineered to provide an air-operated option for reliably supplying thicker material that doesn’t seek its own level. Single post pumps provide a limited amount of pressure, so they may not be as capable of handling thicker materials. The force capacities of the dual posts make this pump stronger, so thicker material can be pumped more easily. The ram-style pump combined with the inductor plate allows material to be pushed down in the container, ensuring the pump holds its prime and  reducing unnecessary grease waste. 

Our Dual Post Ram Pump series is available with 3” or 6” ram, many seal options, a wide range of pump ratios, and a variety of control options. Standard GDPs are commonly used for large drums of NLGI 00-2 grease, whereas G6DPs are perfect for large drums of thicker grease, and GNDPs are made for smaller pails of grease above an NLGI 2. All pump options include a pump, inductor seals, dual post ram, ram control valve, pump air pressure regulator, and ram air pressure regulator.
