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?

They 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)

Assam’s industrial activity is shaped by an energy and process-industry corridor along the Brahmaputra valley, supported by the state’s industrial infrastructure network through agencies such as AIIDC and the Industries & Commerce Department’s identified industrial estates, growth centres, parks, and depots. Key process anchors include Numaligarh Refinery in Golaghat and IndianOil’s Bongaigaon Refinery in Chirang district, both of which create continuous demand for dependable transfer and dosing of viscous and solids-bearing media in utilities, treatment plants, and process units. Upper Assam further strengthens this ecosystem through Oil India’s operations headquartered at Duliajan and major downstream and chemical assets such as BCPL at Lepetkata (Dibrugarh), along with fertilizer manufacturing at BVFCL’s Namrup units. Logistics are reinforced by the Brahmaputra National Waterway-2, enabling bulk movement that supports industrial supply chains across the valley. Across these hubs, progressive cavity screw pumps are well suited for chemical dosing, sludge and effluent handling, filter-press feeding, and transfer of high-viscosity or solids-laden fluids, helping plants maintain stable flow and reliable operations in demanding conditions.

Providing the best screw pumps in Assam 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.
