Premium specialized pumps configured to withstand deep civil grout, high wear materials, and precision tunneling projects.
Japan is a global leader in high-performance infrastructure, seismic structural engineering, and deep subterranean tunnel rehabilitation. From the complex subways of Tokyo and Osaka to the extensive reinforcement networks of the Shinkansen high-speed rail lines, Japan's architectural landscapes demand extreme consistency in construction machinery. Among these essential technologies is the screw mortar pump (commonly classified under progressing cavity or helical rotor-stator pumps).
Unlike conventional concrete pumping, the transport of highly viscous, abrasive mortar requires constant, low-pulsation, high-pressure output. In Japan, strict soil retention schemes, micro-tunneling backfill architectures, and building retrofits dictate that machinery operate with absolute accuracy. This makes importing high-durable, cost-effective equipment a crucial procurement strategy for top Japanese contractors.
Procurement specialists representing civil engineering consortiums in Japan look beyond simple price metrics. They seek specific technological advantages:
Our machines are engineered to align with JIS standards and meet rigorous mechanical performance benchmarks.
At the core of SSG's screw mortar pumps is a high-precision progressing cavity mechanism. Fluid movement is governed by a helical, chrome-alloy steel rotor turning eccentrically within a double-helical stator lined with an elastomer compound. As the rotor turns, progressive cavities are formed, pushing the slurry or abrasive grout smoothly toward the discharge end.
Because cementitious mortar is highly abrasive, our engineering department applies advanced metallurgy processes to extend rotor lifespans. We utilize high-grade carbon structural steel (such as 40Cr or 38CrMoAl) treated with liquid nitriding and hard chrome plating. These methods yield surface hardnesses up to HRC 60, significantly reducing friction wear from hard quartz sand particles.
A progressing cavity pump is only as durable as its stator. Working alongside international polymer labs, we developed specialized elastomeric compounds for various job-site demands:
Modern civil engineering requires customized solutions. Standard cement pumps struggle with complex architectural and environmental specifications. SSG Machinery provides tailored macro-solutions designed for critical municipal sectors:
Our progressive cavity pumps deliver continuous soil stabilization grouting behind shield tunnel segments with zero pulsation, protecting building foundations above.
Ultra-fine concrete and aggregate grout mixtures are fed at high pressure into micro-cracks and structural supports, reinforcing bridges and historical concrete structures.
For mountainous highway bypasses, our diesel shotcrete and mortar spray pumps deliver quick-dry cement mixtures up steep inclines to prevent landslides.

Exporting industrial machinery into Japan requires attention to subtle operational differences. SSG Machinery has streamlined the export process to deliver reliable service to our Japanese partners:
SSG handles all export paperwork, custom declarations, and high-security maritime packing out of major Chinese ports (Qingdao/Shanghai) directly to major Japanese ports including Tokyo, Yokohama, Osaka, and Kobe. We guarantee anti-corrosive vacuum wrapping for all mechanical drives during sea transit.
Screw mortar pumps require periodic stator and rotor replacements due to the highly abrasive nature of concrete slurry. SSG maintains a stocked spare parts department, ensuring replacement stators, seals, coupling rods, and high-performance lubrication packs are dispatched rapidly via air cargo, keeping your job-site downtime to a minimum.
All electronic control panels, variable speed setups, and diesel auxiliary engines are selected and built according to strict Japanese safety and emissions frameworks, ensuring trouble-free site approvals by regional regulators.

Technical answers to common questions from civil engineering contractors and logistics managers.
The wear rate is heavily dependent on aggregate hardness (e.g., high quartz sand content increases wear) and operating pressure. Typically, a hard chrome-plated steel rotor can process 500 to 1,500 cubic meters of standard cement mortar before requiring inspection. Our high-durability natural rubber stators can be replaced independently in under two hours on the job site to minimize operational delay.
Yes. We custom configure motor winds and control panels to match standard Japanese three-phase power supplies: 200V / 220V at both 50Hz (Eastern Japan / Tokyo area) and 60Hz (Western Japan / Osaka area). This prevents motor overheating and ensures stable output across different regional grids.
Progressing cavity pumps deliver a smooth, continuous volumetric flow with virtually zero pulsation. This constant pressure is essential for precise mortar plastering, spraying, and pressure grouting. It reduces mechanical stress on delivery hoses and prevents structural air gaps in dynamic civil engineering applications.
Our factory operates under ISO 9001 quality management guidelines. Every screw pump undergoes a simulated load test, checking pressure levels, flow stability, and thermal limits under sustained backpressure before final packaging and shipment to Japan or other international destinations.
