Positive Displacement Pumps
| Air Diaphragm | Air Diaphragm Positive Displacement Pumps. These positive displacement pumps use the reciprocating action of a flexible diaphragm to pump a fluid. Diaphragm pumps are defined by the manner in which th.... |  |
| Drum | Drum Positive Displacement Pumps. Also called barrel pumps, these positive displacement pumps extract fluids from storage barrels. They are available in both hand-operated and motor operated configura.... |  |
| Gear | Gear Positive Displacement Pumps. These pumps are fixed displacement, meaning they pump a constant amount of fluid for each revolution. They are one of the most commonly used pumps for hydraulic fluid.... |  |
| Metering | Metering Positive Displacement Pumps. These positive displacement pumps move liquids at adjustable flow rates which are precise when averaged over time. Metering refers to this process, and refers to .... |  |
| Peristaltic | Peristaltic Positive Displacement Pumps. These positive displacement pumps move fluids through a flexible tube fitted inside the pump casing. A turning rotor/cam with rollers attached to its outer cir.... |  |
| Progressive Cavity | Progressive Cavity Positive Displacement Pumps. Also known as a progressing cavity pump or eccentric screw pump, these pumps transfer fluid through a sequence of small, fixed shape cavities that progr.... |  |
| Rotary Lobe | Rotary Lobe Positive Displacement Pumps. These positive displacement pumps can handle solids, slurries, pastes, and a variety of liquids. Rotary lobe pumps use rotating lobes to push material through .... |  |
| Sanitary | Sanitary Positive Displacement Pumps. The characteristic that differentiates sanitary pumps from other positive displacement pumps is that they require extreme levels of cleanliness. They require spec.... |  |
| Special | Special Positive Displacement Pumps. These pumps, while operating on the same principles as all positive displacement pumps, are manufactured using materials, hardware, finishes, coatings, or processe.... |  |
