Question 1

What types of vacuum pumps does Kakati manufacture?

Accepted Answer

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.

Question 2

How does a liquid ring vacuum pump work?

Accepted Answer

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.

Question 3

What’s the difference between single-stage and two-stage pumps?

Accepted Answer

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.

Question 4

What is “vacuum level” vs “ultimate vacuum” and why does it matter?

Accepted Answer

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.

Question 5

What are the key factors to consider before buying a vacuum pump?

Accepted Answer

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.

Question 6

What problems can occur if I don’t maintain the seal liquid properly?

Accepted Answer

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.

Question 7

What’s the maintenance schedule for a liquid ring vacuum pump?

Accepted Answer

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.

Question 8

How do I troubleshoot common vacuum pump problems like low vacuum or noise?

Accepted Answer

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.

Question 9

Why choose a liquid ring vacuum pump instead of a dry or oil-lubricated pump?

Accepted Answer

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.

Question 10

Can I retrofit my existing pump with a Kakati solution?

Accepted Answer

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

Question 11

What industries does Kakati serve?

Accepted Answer

Our vacuum pumps and compressors are trusted by major players in industries such as: Power generation, Paper and pulp, Petrochemicals, Sugar, Mineral extraction, Chemical and fertilizer industries. We serve clients in India and over 20+ countries globally.

Question 12

What vacuum level do I need for my industry?

Accepted Answer

The ideal vacuum level depends on your process. For example: Paper and pulp: 50–70 Torr, Power generation: 25–35 Torr, Sugar mills: 100–150 Torr. Our team can conduct vacuum audits and recommend the best solution for your application.

Question 13

What sort of vacuum pump capacity do I need for large industries like sugar or paper mills?

Accepted Answer

Large industries need pumps with high flow (often thousands of m³/hr) and specific vacuum levels to match processes like evaporators or dewatering. Kakati’s high-capacity KXL series is designed precisely for such heavy-duty applications.

Question 14

How can I reduce energy consumption in my vacuum system?

Accepted Answer

Upgrading to a Kakati energy-efficient model, fixing leaks, and optimizing system design can lead to 20–30% energy savings. We also perform performance audits to identify inefficiencies.

Question 15

How do I know if my vacuum pump is wasting energy?

Accepted Answer

Common energy wasters include leaks, incorrect vacuum level, poor seal liquid management, and inefficient motors. Kakati offers detailed performance audits to measure usage and recommend energy-saving upgrades.

Question 16

Are there any environmental or regulatory concerns for vacuum pump operation?

Accepted Answer

Yes. Concerns include water usage, discharge, sealant disposal, noise, and emissions. Kakati ensures compliance with international standards and offers eco-friendly designs such as water-recirculation systems and low-noise operation.

Question 17
