Engineered to handle high-viscosity structural mortars, shotcrete, and heavy grouting applications.
Understanding the technical pumping needs of the Division of Rajshahi, Bangladesh.
Rajshahi, traditionally famous for its silk and agricultural outputs, is undergoing a rapid industrial and structural transition. Governed by the vision of the Rajshahi City Corporation (RCC) and the broader Bangladesh urban growth strategies, the region is experiencing massive investments in multi-story residential towers, commercial zones, road bypasses, and industrial parks.
This construction boom demands high-efficiency civil engineering machinery. Traditional manual plastering and cement transporting methods are no longer sufficient to meet tight project deadlines. Screw mortar pumps, also known as progressing cavity pumps, have become indispensable in this region. They provide continuous, pulsation-free pumping of high-density aggregates, raw grouting mixtures, and self-leveling floor screeds across vertical heights of over 40 meters.
Furthermore, the local soil profile and geography near the Padma River basin demand specialized foundation grouting and riverbank reinforcement. Our range of progressive cavity screw pumps offers the exact pressure control and slurry wear-resistance required for local geotechnical remediation projects, ensuring structural stability for new builds.
• Urban Infill & Multi-story Construction: Delivering plaster and fine concrete to upper floors without mechanical cranes.
• Padma River Grouting & Soil Consolidation: High-pressure injection of concrete slurries to prevent river bank erosion.
• Industrial Refractory Lining: Applying heat-resistant mortar linings in high-temperature kilns in surrounding industrial zones.
All SSG Machinery screw pumps sent to Bangladesh are standard-built with high-efficiency motors optimized for 400V, 50Hz, 3-Phase power supply, matching Rajshahi’s grid standards.
A deep comparative look at rotor-stator mechanics and concrete peristaltic systems.
Progressing cavity (screw) pumps utilize a high-precision metal rotor turning inside a flexible elastomeric stator. As the rotor rotates, it creates a series of sealed cavities that move axially from the suction end to the discharge end. This displacement mechanism offers major benefits over traditional piston or centrifugal pumps when handling thick construction materials:
Piston pumps deliver material in pulses, leading to uneven plastering and excessive rebound waste. Screw pumps deliver a continuous, smooth flow of mortar, allowing spray nozzles to coat surfaces evenly, saving up to 20% on materials.
Whether pumping cement paste, clay slurry, or aggregate-filled mortars, our G-series and customized hopper pumps handle particles up to 6mm without clogging. This is crucial for Rajshahi projects using local sand.
By utilizing high-grade nitrided steel rotors paired with natural rubber stators, the friction coefficient is minimized. This design resists the abrasive forces of quartz-heavy mortar slurries common in South Asia.
Each pump is powered by a high-torque geared motor with an optional variable frequency drive (VFD). This configuration allows operators in Rajshahi to regulate the flow rate from 0.5 m³/h to 8 m³/h, adapting from precision chemical grout injection to high-volume vertical mortar transport. Additionally, our industrial high-pressure pumps feature robust double-lip mechanical seals or gland packings to prevent backflow into the drive train, extending bearing life even under high-duty operations.
Providing smooth delivery and operation from China factories to Bangladeshi job sites.
Rajshahi experiences high summer temperatures, often exceeding 40°C, alongside heavy monsoon seasons. Standard electric motors can quickly overheat or short-circuit in these conditions. To prevent this, SSG Machinery equips all export-bound pumps with:
