Engineered for high viscosity, abrasive materials, and continuous operation in demanding environments from Lisbon to Porto.
Portugal’s architecture and construction sectors are undergoing a significant transition. From the extensive historical restorations in Lisbon’s Pombaline districts and Porto’s UNESCO World Heritage core, to the high-efficiency residential projects in the Algarve and metropolitan commercial expansions, modern infrastructure requires equipment designed for durability, accuracy, and reliability.
Traditional gravimetric casting and basic manual application methods are no longer sufficient to meet modern performance requirements. Current projects call for rheologically advanced mortars, such as polymer-modified structural repair grouts, thixotropic mortars, lime-based formulations for heritage conservation, and highly liquid self-leveling screeds (argamassas autonivelantes).
Transferring and applying these materials at scale requires robust, mechanical, high-pressure solutions. The Screw Mortar Pump—a progressive cavity system based on a precision-matched rotor and stator geometry—has become the standard choice. These pumps provide a pulse-free, continuous flow rate that ensures uniform material density, prevents phase separation, and minimizes mechanical strain, meeting the demands of Portuguese general contractors, restoration experts, and industrial floor laying companies.
At the center of a screw mortar pump's performance is the progressive cavity pumping (PCP) principle. The pump features a single-helix metallic rotor that rotates eccentrically within a double-helix elastomeric stator. This movement creates a series of sealed cavities that progress from the suction port to the discharge end, carrying the material continuously.
This design offers distinct advantages for mortar applications:

From raw steel to high-performance machinery: How we build reliability into every component.
Producing reliable, low-wear stator/rotor systems requires high-precision equipment. Our manufacturing plant operates a specialized fleet of industrial heavy-duty machines to maintain micro-millimetric tolerances, ensuring consistent quality for all components.
Purchasing directly from Henan SSG Machinery Co., Ltd. allows Portuguese construction enterprises to combine cost efficiency with reliable product quality. By sourcing from a direct manufacturer rather than third-party distributors, buyers gain access to several key benefits:
European local equipment distributors often apply significant markups to account for regional logistics and localized showrooms. By dealing directly with SSG’s advanced central factory in Zhengzhou, Portuguese contractors can save between 30% to 50% on capital expenditure, without compromising on materials or build quality.
Our rotors are manufactured from high-grade alloy steels (such as 40Cr or 304/316 Stainless Steel) and undergo heat treatment to achieve surface hardness levels exceeding 60 HRC. Stators are molded from custom-compounded elastomeric compounds optimized for specific chemical and physical requirements, ensuring long service life under high pressure. These systems are designed to fully comply with European mechanical standards, ensuring smooth integration with local projects.
Rotors and stators are consumable components that eventually require replacement due to the abrasive nature of cement and silica sand. SSG provides reliable logistics and shipping channels directly to major Portuguese ports, including Porto (Leixões) and Lisbon, minimizing downtime and maintaining high operational efficiency for your projects.
High-efficiency progressive cavity pumps designed for advanced industrial applications and structural soil consolidation.
Screw mortar pumps are versatile tools used across a range of structural, industrial, and restoration projects throughout Portugal:
In historic urban centers like Lisbon and Porto, building rehabilitation requires careful structural reinforcement. Screw mortar pumps are widely used to inject low-viscosity, non-shrink grout or lime-based mortars into cracked stone walls and masonry foundations. The pulse-free flow ensures thorough voids filling without placing undue stress on older structures.
Modern commercial developments and hotel resorts in the Algarve demand perfectly level subfloors for large-area tiling and wood installations. Progressive cavity screw pumps are ideal for conveying highly liquid, self-leveling cementitious and anhydrite screeds over long distances, maintaining a steady, uninterrupted flow that prevents dry joints.
Coastal structures along the Atlantic coastline are exposed to high humidity and salt-laden air. Applying high-performance, water-resistant rendering mortars requires spraying equipment that can maintain consistent pressures, ensuring a strong, void-free bond with the substrate.
For municipal subway expansions and railway line improvements, diesel and electric-powered screw pumps are essential for slope stabilization, micro-piling, soil nailing, and contact grouting, delivering reliable performance under difficult site conditions.
