At Kakati Pumps, we specialize in the design and manufacture of liquid ring vacuum pumps and compressors. Our product range includes: Single-stage pumps like the KV-Series, Two-stage pumps such as the KDS-Series, KVT-Series, Energy-efficient pumps like the KEN-Series, High-capacity pumps like the KXL-Series, and Customized vacuum systems for specialized industrial needs. All our products are built for durability, energy efficiency, and ease of maintenance.

A liquid ring vacuum pump works by using a rotating impeller inside a casing partially filled with sealing liquid (usually water). As the impeller spins, a ring of liquid forms and creates sealed spaces that trap and compress gases. At Kakati, our pumps are engineered to ensure maximum efficiency and reliability, even in demanding applications.

Single-stage pumps (like our KV-Series) are ideal for standard vacuum requirements. Two-stage pumps (KDS, KVT-Series) achieve deeper vacuum and are more energy-efficient at lower pressures. Kakati offers both and helps you choose based on your performance and cost goals.

The ‘vacuum level’ refers to the operating pressure your process needs (e.g., in Torr, mbar, or mmHg), while ‘ultimate vacuum’ is the lowest pressure the pump can ideally reach under perfect conditions. At Kakati Pumps, we ensure our specifications list both, ensuring consistent real-world performance.

Consider vacuum level, capacity (m³/hr or CFM), gas/vapour composition, duty cycle, temperature, and material compatibility. Kakati conducts free pre-selection audits to ensure clients get the right match for their process.

Poor quality or improper volume of seal liquid can lead to low vacuum, overheating, vibration, or corrosion. Kakati provides closed-loop seal-water systems and training to prevent such issues.

We recommend: Monthly inspection of seal liquid, Quarterly checks on bearings and clearances, Annual overhauls for continuous duty pumps. Kakati Pumps provides AMC (Annual Maintenance Contracts) to ensure optimal performance.

We at Kakati usually check: Leaks in the inlet or piping, Seal liquid level or flow, Filters or strainers clogging, Impeller-to-casing clearance, Blade, bearing, or motor wear. We also provide a technical helpline and troubleshooting guides.

Liquid ring pumps are better for wet gas, vapours, and condensables — they handle contaminants easily, have fewer moving parts, and run cooler with less maintenance.

Yes. We offer retrofit kits and upgrades that improve efficiency and extend the lifespan of existing systems without major layout changes.
