Unique Pump Systems Alfa Series — Rotary Lobe Pump Range for Kolkata
A lobe pump is a type of positive displacement (PD) pump that transfers fluid using two or more lobed rotors rotating inside a pump casing. Unlike gear pumps, the rotors in a rotary lobe pump never come into direct contact with each other — they are synchronised by external timing gears located in a separate gear case. This fundamental design feature makes them the preferred choice for applications in Kolkata requiring hygienic, gentle, and contamination-free fluid handling.
The lobe type pump in Kolkata creates sealed chambers between the rotors and casing as they rotate. Fluid is trapped in these chambers at the inlet and positively displaced to the outlet with every rotation — delivering a smooth, metered, near-pulsation-free flow. The absence of metal-to-metal contact in the pumping zone means the pump can handle shear-sensitive, particulate-laden, and viscous fluids without degradation.
Understanding the working principle of a rotary lobe pump helps you appreciate why it is the correct choice for hygienic and gentle fluid transfer in Kolkata's processing plants. Here is a step-by-step breakdown of the operating cycle:

As the lobes rotate outward and away from each other at the inlet, expanding cavities create a low-pressure zone. Fluid is drawn in smoothly from the suction port without turbulence or agitation.
Each lobe pocket traps a precise volume of fluid between the rotor and the casing wall. This trapped volume is then carried around the outer circumference from the inlet toward the outlet — gently and without shear.
At the outlet, the lobes rotate back toward each other, reducing the volume of the fluid pocket and forcing the fluid out through the discharge port at controlled, consistent pressure.
External timing gears in the separate gear case keep both rotors precisely synchronised at all times — maintaining the critical clearance between them without any contact. This is what makes the lobe pump hygienic and gentle on the product.
Our Alfa Series rotary lobe pumps in Kolkata are available in low, medium, and high-pressure configurations to match the full spectrum of industrial and hygienic applications in West Bengal. Below is the complete performance range from Unique Pump Systems:
| Series / Model | Port Size | Max Pressure | Max Speed (RPM) | Capacity (LPM) | Best Suited For |
|---|---|---|---|---|---|
| UAL-100 | 1" | 7 kg/cm² | 960 | Up to 100 | Oils, Syrups, Chemicals |
| UAL-200 | 2" | 7 kg/cm² | 720 | Up to 300 | Dairy, Cream, Beverages |
| UAL-400 | 4" | 5 kg/cm² | 600 | Up to 750 | Tomato Paste, Sludge, Viscous Fluids |
| UAL-600 | 6" | 3 kg/cm² | 400 | Up to 1000 | Effluent, High Solid Content |
| UAL-1200 | 12" | 3 kg/cm² | 200 | Up to 2000 | Industrial Bulk Transfer |
Unique Pump Systems manufactures the Alfa Series in three pressure variants to match your specific operating requirements in Kolkata:
Standard Models
Low-pressure configuration engineered specifically for delicate food-grade and dairy applications in Kolkata where gentle handling and product integrity are the priority.
Teflon Bearing Models
Medium-pressure variant with Teflon/Rulon bushings for chemical solvents, cleaning agents, and applications in Kolkata where standard bearing materials are incompatible with the fluid.
Overhung Bearing Models
High-pressure configuration for viscous oils, industrial resins, and heavy-duty continuous transfer in Kolkata where maximum mechanical robustness under pressure loading is required.

While other lobe pump manufacturers in Kolkata focus only on flow rate, Unique Pump Systems focuses on the entire lifecycle of your pump. Here are the design features that set our Alfa Series apart for Kolkata's industries:
A generous physical distance between the pump head and gear case prevents gear oil from ever migrating into your product. For pharmaceutical and food-grade applications in Kolkata, this eliminates the risk of costly batch rejection and compliance failure.
Precision-machined, hardened timing gears ensure that even under 24/7 continuous full-load operation in Kolkata's factories, rotor synchronisation is maintained without slipping or jamming — extending the operational life of your investment.
Tool-free front cover access to rotors without disconnecting pipework. Fully CIP (Clean-in-Place) and COP (Clean-out-of-Place) capable, making it the ideal choice for dairy, beverage, and pharmaceutical production lines in Kolkata.
Unlike centrifugal pumps, the positive displacement lobe pump provides a gentle rolling action. It handles whole curds, cherry tomatoes, polymer gels, and intact fruit pieces without mechanical degradation or quality loss — ideal for food processors in Kolkata.
Shafts, gears, and bearings are engineered to be removed as a single cartridge assembly — reducing maintenance downtime by up to 60% compared to conventional designs that require full disassembly.
Flow direction can be reversed simply by reversing motor rotation — without any internal modifications. This provides exceptional operational flexibility for filling, dosing, and CIP return-flow applications in Kolkata.
Unique Pump Systems are designed for high mechanical efficiency — meaning less energy consumption, lower operating cost, smaller motors, and lower drive costs for your Kolkata plant. Rotor shafts are sealed by hygienic mechanical seals or by packed glands selected for the duty conditions. A generous distance separating the pump head from the gear case eliminates any risk of cross-contamination.
Positive, uninterrupted displacement by specially designed rotors creates a steady, gentle pumping action that does not shear, agitate, or aerate the product — protecting the integrity of sensitive materials throughout the entire transfer process in Kolkata.
The easy-clean pump head is ideal for in-place cleaning or can be rapidly stripped for manual cleaning without disconnecting the pipework. Ports are threaded or flanged to suit customer requirements. Pumping chambers are constructed without pockets or crevices that could harbour bacteria or contaminants. There are no internal bearings in the pump head. Solid stainless steel AISI 316 quality pump head, rotors, and shafts. Robust cast iron gear case enclosing oil-lubricated rolling bearings and precision timing gears.
