Neptune Pumps Variable Oil By-pass™

The unique Variable Oil By-pass feature on Neptune pumps provides better valve performance than variable linkage designs. Because they are idle during the bypass portion of suction and discharge strokes, valve checks have extra time to seat—even in heavy liquids.

Hollow pistons with reduced-diameter “noses” reciprocate in their cylinders. Metering rods fit into the pistons. As the pistons move forward, ports are blocked by the tips of the metering rods, which stops the bypass. Oil is pushed through the ports and into the pumps’ diaphragms.

Adjusting the micrometer dial will move the metering rod and raise or lower pump capacity. With the metering rod moved in, its tip closes the port sooner, allowing for less bypass and more pumping action. Conversely, with the metering rod moved out, its tip closes the port later in the stroke for more bypass and less pumping.  Order online today, send us a Request for Quote or contact Pumping Solutions for more information on Neptune pumps.
