Single post ram grease pumps

Our single post ram-style pumps include the GSP and GSPM Series. These mid-size pumps are designed to consistently pump materials all the way to the bottom of the pail, significantly reducing the amount of grease wasted.

Features and Benefits

Product details

Single post ram grease pumps provide an air-operated system for reliable production supply with viscous material that doesn’t seek its own level. Unlike stick pumps, our ram pumps use an inductor plate to push material down in your container, reducing all unnecessary adjustments and minimizing the amount of air that enters your system. Our GSP and GSPM pumps are designed to ensure you can pump material at the bottom of your pail, which significantly reduces the amount of material wasted. The design of these pumps allows the pump suction to hang in the air during container changes rather than having to put it on the floor. 

GSP/GSPMs pump grease right out of its original container, so you can begin the dispensing process in an efficient manner. Plus, our Miniature Single Post Ram Pumps (GSPMs) provide a more compact design than the standard GSP model, helping users who need a design fit for a smaller location. These Miniature Single Post Ram Pumps also have an optional portability kit, making them easy to roll around and fill reservoir/regulators. All pump models include the pump, inductor seals, single post ram, ram control valve, pump air pressure regulator, and ram air pressure regulator. These pumps will work with NLGI 00-3 materials and are available in a variety of configurations.
