Vacuum Pump Technologies and Materials to Best Suit Your Priming Application

LYNN vacuum priming system designs provide our customers with a selection of vacuum pump technologies and materials of construction to best suit the requirements and preferences of the installation. LYNN designs assure reliability and ease of installation. With a LYNN design, regardless of the vacuum technologies chosen, you can be assured of the system reliability.

Rotary Vane Oil Lubricated or Oil-Less Vacuum PumpsRV pump

Rotary vane vacuum pumps represent the most efficient and cost effective solution for priming applications. Oil lubricated units provide the highest vacuum levels. In rotary vane technology, the rotor, the only continually moving part, has a number of slots machined along its length into which fit sliding vanes that ride on a film of oil. The rotor rotates within a cylindrical stator. During rotation, centrifugal force extends the vanes from their slots, forming individual compression cells. Rotation decreases the cell volume, increasing the air pressure. Its compact size, quiet operations and overall reliability makes it the ideal choice for priming applications.

When oil lubrication is undesirable, the eco-friendly oil-less/dry running rotary vane vacuum pumps are robust, economical, and require little maintenance.

Liquid Ring Vacuum PumpsLR pump

When a fresh water source is available liquid ring vacuum pumps are an ideal selection to achieve high vacuum levels with little to no maintenance.  With no metal-to-metal contact and several materials of construction available,  liquid ring vacuum pumps’ robust construction are the best choice for applications with corrosive gases.

Liquid vacuum ring pumps and compressors utilize rotating positive displacement technology and are typically used in liquid ring vacuum pump applications, but can also be used as a gas, or liquid ring compressor. These sturdy pumps are built for heavy duty, wet and humid applications where most other pumps’ performance will drop due to abrasion and lime scale from the process. The larger liquid ring pumps are often part of engineered systems designed to meet even the highest demands.

The impeller rotates friction free within the pump casing. A rotating liquid ring seals the impeller on the front and seals its blades against one another. In order to keep the liquid ring stable, liquid is also permanently sucked into the compression chamber and is output together with the conveyed gas. The eccentrically arrangement of the impeller within the casing creates variable compression chambers between the impeller blades during rotation, which causes the conveyed gas to be compressed within a full revolution.

Dry Reciprocating Piston Vacuum PumpsRP pump

Dry Reciprocating pumps are high vacuum, oil lubricated, low speed belt driven vacuum pumps. These pumps have not changed much over the years, but continue to be desired for their rugged construction.

When a V-APCO priming system is desired LYNN can provide an equal vacuum priming system for your application or specified system.
