Industrial vacuum pump suppliers stock vacuum pumps in a variety of sizes and types for a variety of uses. One typical vacuum pump that most suppliers offer is the liquid ring pump. A liquid ring pump rotates a vaned impeller to compress gas inside the pump in the cylindrical casing. Water is fed into the pump by this action, which forms a moving cylindrical ring inside the casing. This rink seals the space between the impeller vanes of the pump, forming compression chambers. This causes air to become trapped in the compression chambers, which is then compressed and sent to the discharge port. The cycle then starts over.
This kind of pump provides many benefits over other vacuum pump types for a variety of reasons, such as:
Fewer components: A liquid ring pump does not have as many components as other vacuum pump systems. The liquid ring pump has fewer parts, which leads to increased pump strength and increased rigidity in the design. Liquid ring pumps are also easier to maintain because they contain fewer parts. Fewer parts equals fewer components that can break down.
Compact size: Due in part to the lack of extra components, a liquid ring pump is often smaller than other vacuum pump types. This makes them ideal for use in tight spaces or other areas with space constraints.
Reliability: Liquid pumps use no reciprocating parts, which means that there is less that can go wrong in this pump style. Fewer parts and simpler systems lead to increased overall reliability for the pump.
Material variety: Most industrial vacuum pump suppliers can manufacture liquid ring pumps from a variety of materials to suit different uses, such as more corrosion resistant materials, or tougher materials for harsh environments.
