Water circulating vacuum pumps have specific sealing pipe requirements based on inlet pressure. When the inlet pressure is 0.03 MPa or less, sealing pipe parts do not require installation structure design, simplifying setup. These pumps handle a maximum working pressure (inlet + pumping pressure) of 1.0 MPa for heads ≤75m or 1.6 MPa for heads >75m, with special configurations allowing up to 2.5 MPa. Designed for water or similar liquids, they offer advantages like simple construction, compact size, isothermal compression, water-based sealing (eliminating lubrication needs), and reliable operation—making them ideal for labs and small-scale industrial applications.
Key Points Explained:
-
Inlet Pressure Threshold for Sealing Pipes
- Below 0.03 MPa: No structural design is needed for sealing pipes, reducing installation complexity.
Why this matters: Purchasers benefit from lower setup costs and simplified maintenance in low-pressure applications, common in lab environments.
- Below 0.03 MPa: No structural design is needed for sealing pipes, reducing installation complexity.
-
Maximum Working Pressure Limits
- Standard configurations:
- 1.0 MPa for pumps with heads ≤75m.
- 1.6 MPa for heads >75m.
- Special configurations: Can reach 1.6 MPa or 2.5 MPa for demanding applications.
Practical implication: Buyers must match pump specifications to their system’s pressure requirements to avoid over- or under-specification. For high-pressure needs, confirm special configurations upfront.
- Standard configurations:
-
Compatible Media
- Works with water or liquids chemically/physically similar to water.
Consideration: Ensures versatility for labs handling non-corrosive fluids but may limit use with solvents or aggressive chemicals.
- Works with water or liquids chemically/physically similar to water.

Operational Advantages
- Simplified Design: Low-precision parts reduce manufacturing costs and ease repairs.
- Compact & Efficient: High-speed operation allows direct motor coupling, saving space.
- Isothermal Compression: Minimizes heat buildup, protecting sensitive samples.
- Maintenance-Free Sealing: Water-based sealing eliminates lubrication needs.
Buyer’s perspective: These features translate to lower lifetime costs, minimal downtime, and adaptability to tight lab spaces.

Mechanism of Action
- Uses an eccentric impeller to create a swirling water ring, acting as a "liquid piston" to suction and compress gases.
Why it’s reliable: The mechanical simplicity reduces wear-prone parts, ensuring longevity even with continuous use.
