The 12 HWDH75/100 vertical piston cement injection pumps shipped to Vietnam this time are specifically designed for various complex grouting scenarios, combining practicality and advanced technology to become a powerful tool in engineering construction.
This high pressure cement grout injection pump has a wide range of applications. In civil engineering, it can be used in key aspects such as dam foundations, tunnels, mining construction, soil nailing walls, anchor cables, and rock anchors; in structural engineering, it can efficiently complete building and bridge repair, foundation reinforcement, foundation lifting, and soil and rock grouting; in road construction, it is suitable for needs such as pavement sealing and slab jacking; in marine engineering, it can handle underwater foundations, bridge piers, breakwaters, and coastline foundation grouting; at the same time, it also plays an important role in scenarios such as mine tunnel lining, well waterproofing, municipal pipeline covering, slope grouting, and deep well casing sealing, comprehensively meeting the grouting requirements of different projects.
In terms of core performance, the
HWDH75/100 vertical piston cement injection pump demonstrates superior advantages. The cement grout injection pump employs a dual-pump design, equipped with a single/dual-pump switching valve, enabling flexible switching between low-pressure, high-flow and high-pressure, low-flow modes: In low-pressure mode, both pumps operate simultaneously, achieving a flow rate of 0-75 L/min and a pressure range of 0-50 Bar (725 psi), suitable for large-area, rapid grouting; in high-pressure mode, a single pump operates, with a maximum pressure of 100 Bar (1450 psi) and a flow rate of 0-40 L/min, easily handling demanding conditions such as high-pressure fracturing grouting. Its piston diameter is 100 mm, stroke is 150 mm, and it features an M27x2 discharge pipe and a G2'' inlet pipe, ensuring stable and efficient grouting.
The HWDH75/100 vertical piston cement injection pump features a compact design with a skid-mounted or wheeled chassis (customizable), weighing only 390 kg and measuring 1,040 x 550 x 1,650 mm, facilitating transportation and on-site deployment. Equipped with a digital display counter, it displays and accumulates working cycles in real time, simplifying operation management and maintenance. Flow and pressure are infinitely adjustable to precisely match different grouting process requirements. A built-in emergency unloading valve allows for instant pressure relief in emergencies, ensuring operational safety. A fully hydraulic shaft drive ensures stable and reliable operation, while offering both water and air cooling options to suit various climates, including high temperatures and extreme cold. Its application is unrestricted, and its ease of operation and low maintenance costs significantly reduce customer operating costs.
