Sliding Vane Pumps
These pumps have several free vanes 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.
Gas Compressor Pumps
The single and two-stage reciprocating gas compressors create a low-pressure area in the pumping chamber when the piston moves from the highest point of the stroke to the lowest point. Gaseous product (at a higher pressure in the tank) moves into the pumping chamber of the gas compressor. This volume of gas is then displaced when the piston moves to the top of the stroke. Equipped with high-efficiency valves, ductile iron pistons, self-adjusting piston rod seals and other robust features, these reciprocating gas compressors are designed to provide maximum performance and reliability under the most severe service conditions.
