Screw Pump Manufacturer in West Bengal

What is a Progressive Cavity Screw Pump?

A progressive cavity pump (also called a single-screw or eccentric screw pump) is a positive displacement pump that moves fluid through sealed cavities formed between a helical rotor and a stator. This creates stable, low-pulsation flow, making it ideal for:

• Shear-sensitive fluids
• Viscous products
• Slurries and abrasive media
• Metered dosing and accurate transfer

How it Works

As the rotor turns inside the elastomer stator, cavities "progress" from suction to discharge. The result is:

• Predictable flow (good for dosing/feeding)
• High suction capability for difficult fluids
• Gentle pumping action (reduced product damage)

Performance Range & Model Overview

We provide the following specifications:

• Single stage: up to 6 kg/cm² (max)
• Double stage: up to 12 kg/cm² (max)
• Four stage: up to 24 kg/cm² (max)

Important sizing note: The brochure data is referenced to water at ambient conditions; RPM and absorbed power vary with actual viscosity of the pumped media.

Materials of Construction

• Housing / wetted parts options: Cast iron, cast steel, CF8 (AISI 304), CF8M (AISI 316), AISI 316L, with fabrication/finishes available for food-grade requirements.
• Rotating parts: rotor/shafts/coupling rods in SS304/SS316/SS316L, alloy steels, and other alloys (as per application).
• Shaft sealing: gland packing or mechanical seals.
• Stator elastomers (selection as per chemical + temperature): Natural rubber, Nitrile, EPDM, Hypalon, Neoprene, Viton, Silicone + food-grade options, typically 60–70 Shore A.

Where These Pumps Are Used

Common applications

• Filter press feed, sludge transfer, thickened slurry handling
• Polymer dosing and chemical dosing (consistent metered flow)
• Effluent treatment plants (ETP/STP), waste handling
• Paints, inks, resins, adhesives (high viscosity)
• Food & beverage viscous transfer (syrups, sauces, concentrates)
• Mining/mineral slurries and abrasive media transfer

Why progressive cavity pumps here?

Progressive cavity pumps handle high viscosity + solids with controlled flow better than many centrifugal setups.

Optional Accessories

• Dry running protection: Monitors stator temperature (thermoelectric sensing) and trips the motor if dry-running causes overheating — helps prevent stator damage.
• Pressure relief valve: Recommended when the pump may run against a closed valve or line blockage; improves plant safety.

How to Select the Right Screw Pump

To recommend the correct pump model, please share:

• Media name + concentration + pH/chemistry
• Viscosity range (cP) + temperature
• Solids % / particle size / abrasiveness
• Required flow rate (m³/hr or LPH)
• Required discharge pressure / head
• Duty cycle and installation details (flooded suction, suction lift, piping)

West Bengal's industrial ecosystem is driven by the Kolkata region and a set of large process and heavy-industry hubs supported by agencies such as the West Bengal Industrial Development Corporation (WBIDC). Along the lower Hooghly, the Haldia industrial belt combines port-led logistics with petrochemicals, anchored by Haldia Petrochemicals' naphtha-based petrochemical complex and the Haldia Dock Complex, which together support large-scale movement and processing of liquid and bulk cargo.

In the western part of the state, the Durgapur industrial area forms a core node for metals and engineering, with major SAIL units such as Durgapur Steel Plant and Alloy Steels Plant located in Durgapur. Closer to Kolkata, export-oriented manufacturing is also supported by the Falta Special Economic Zone (FSEZ) near Kolkata. Across these clusters, progressive cavity screw pumps are commonly applied for chemical dosing, viscous and solids-laden transfer, effluent and sludge handling, and filter-press feeding, where consistent flow and gentle handling help stabilize operations and protect product quality.

Providing the best screw pumps in West Bengal is our mission and serving industrial sectors here with quality products is our privilege.

FAQs

What is the difference between a screw pump and a progressive cavity pump?

Progressive cavity pumps are commonly called single-screw/eccentric screw pumps; multi-screw pumps (twin/triple) are a different design used often for lubricating liquids

Can your pump handle abrasive slurry or sludge?

Yes, Progressive Cavity pumps are widely used for slurry/sludge; material and stator selection are critical for wear life.

What stator materials do you offer?

Natural rubber, NBR, EPDM, Viton, Silicone and food-grade options (selection depends on chemical/temperature).

Do you offer mechanical seals?

Yes, mechanical seals or gland packing options are available.

How do I prevent dry running damage?

Use dry running protection (temperature sensing/trip) and proper instrumentation.

Do performance values change with viscosity?

Yes, RPM and absorbed power depend on actual viscosity.
