Positive Displacement Pumps

Blackmer Pumps have a number of vanes that are free to slide into or out of slots in the pump rotor. When the pump driver turns the rotor, centrifugal force, push rods, and/or pressurized fluid causes the vanes to move outward in their slots and bear against the inner bore of the pump casing forming pumping chambers. As the rotor revolves, fluid flows into the area between the vanes (pumping cambers) when they pass the suction port. This fluid is transported around the pump casing until the discharge port is reached. At this point the fluid is squeezed out into the discharge piping.

FMC Pumps have provided exceptional performance and value since their introduction in 1884. As a pioneer and global leader in providing high pressure fluid pumping solutions within a variety of markets, FMC Technologies offers a broad array of high pressure piston and plunger reciprocation pumps within the industrial, oil & gas, sewer cleaning, horizontal and vertical drilling, reverse osmosis and agricultural markets. Piston and plunger pumps are characteristically high efficiency pumps with rated efficiencies of 85%-90% and in some cases actual efficiency higher than rated. The high efficiency is due to the direct energy transfer directly to the fluid through the reciprocating action and positive displacement of the fluid.

Haight Pumps has been providing industry with simple, rugged and dependable internal gear pump manufacturing. These pumps are built on the proven reliability of the "gear within a gear design", which they pioneered. This simple concept results in a stronger pump with fewer parts. This gear design also functions exceptionally well at standard motor speeds in close-coupled mounting arrangements. This eliminates both the need for a gear reducer, and misalignment problems.

Grundfos Pumps is one of the world's largest manufacturers, providing water for homes, farms, commercial buildings, and industrial uses. Featuring unique stainless steel construction and the latest in electronics, Grundfos pumps are recognized for reliability and value throughout world-wide -- wherever water moves.

Tech-Mag Pumps have been engineered for efficient, highly reliable, leak-free pumping in a wide range of chemical processes and critical OEM applications. While other pumps may look similar, the design features, reliability and performance capabilities of the TECH-MAG far exceed that of other manufacturers. The compact design, and some models being directly interchangeable, allows a TECH-MAG retrofit without costly system or piping modifications.
