Screw Pump – Datgur Engineering
Screw Pump – Reliable Progressive Cavity Technology
Datgur Engineering offers advanced Screw Pump solutions designed for smooth, continuous, and efficient transfer of viscous and abrasive fluids.
A Progressive Cavity Screw Pump is a rotary positive displacement pump consisting of a precisely machined metallic rotor and an elastomer stator.
This unique construction ensures consistent flow, high efficiency, and reliable performance across various industrial applications.
Rotor & Stator Geometry
The pump consists of a precision-engineered metallic rotor rotating within an elastomer stator.
This unique geometry creates sealed cavities that progress from suction to discharge.
The design maintains an effective sealing line under both static and dynamic conditions, ensuring high volumetric efficiency and reliable performance even in demanding operating environments.
Pulsation-Free Flow
The cavities move smoothly from the suction side to the discharge end, carrying fluid without pulsation.
This steady, non-pulsating flow is critical for protecting downstream equipment, sensitive instruments, and maintaining process stability in industrial operations.
Process Flow & Optimization
Screw Pumps are engineered to enhance process efficiency through optimized flow dynamics.
They create ideal flow patterns that help maintain reaction rates and ensure proper mass transfer.
Uniform distribution of fluids ensures stable process conditions and improved operational performance.

Frequently Asked Questions
What makes the Screw Pump ideal for viscous fluids? The Progressive Cavity design uses a metallic rotor and elastomer stator to move fluid smoothly and can handle liquids up to 1,00,000 cPs without efficiency loss or pulsation.
Does this pump require a foot valve for priming? No, it is inherently self-priming and clears air from the suction line automatically.
Can the pumping direction be changed? Yes, it offers reversible suction and discharge capability.
How does it protect downstream equipment? It delivers pulsation-free flow, preventing pressure spikes that may damage sensitive equipment.
Is it suitable for fluids containing solids? Yes, its non-clogging design and rotor-stator geometry allow effective handling of abrasive fluids and certain solid particles.
