A slurry pump is specifically designed to transport abrasive or corrosive media containing solid particles. Its working principle relies on the rotation of the pump shaft driving the impeller. Under the impeller’s action, the solid-liquid mixture gains energy to generate pressure and velocity for effective material conveyance. During design, engineers prioritize the medium’s abrasiveness and particle size to ensure high efficiency and long-term stability. SANLIAN PUMP offers tailored solutions to meet diverse application needs, ensuring reliable performance under complex and variable operating conditions.

The design of chemical pumps follows standards such as ISO and API 610, and uses stainless steel, duplex steel, Hastelloy and fluorine-lined materials. It is suitable for environments with strong corrosion, high temperature and media containing particles, ensuring the stable operation of the equipment. The sealing system offers a variety of options, with a leakage rate lower than industry standards, meeting environmental protection and safety requirements. By optimizing the impeller and flow channel through CFD technology, the efficiency is increased by 15% to 25% and energy consumption is reduced. It supports variable frequency speed regulation, can be integrated with an intelligent monitoring system, and is suitable for automated production. The key components are modularly designed, making maintenance simple and reducing downtime by more than 50%.

The mixed flow pump combines centrifugal and axial forces, directing liquid to exit the impeller at an inclined angle. Its "pull-out" structure allows inspection and replacement of the impeller and shaft seals without disconnecting pipelines. Suitable for conveying clean water or liquids with similar physical/chemical properties (including mildly contaminated water), it is widely used in agricultural irrigation, municipal engineering, industrial water treatment, power plant circulation, and urban water supply/drainage.

As a centrifugal pump, the multistage pump features tightly combined inlet/outlet sections and intermediate stages via tie rods. Multiple impellers generate higher static pressure than conventional centrifugal pumps, significantly increasing the pump head. Capable of handling diverse fluids (e.g., clean water, sewage, oil, corrosive, or viscous liquids), its compact design makes it ideal for space-constrained installations. Additionally, wear- and corrosion-resistant materials are used to ensure long-term stability and reduced maintenance costs.

Driven by a submersible motor, the submersible electric pump creates a vacuum at the impeller inlet to draw in water. Under the impeller’s action, water gains pressure and kinetic energy, is guided by the volute, and is discharged through the outlet pipe. Requiring no above-ground power equipment, it saves installation space and reduces construction costs. With a compact structure, smooth operation, and low noise, it is suitable for underwater drainage in agricultural irrigation, urban drainage, and industrial cooling cycles. SANLIAN PUMP optimizes corrosion and wear resistance during design to adapt to diverse and complex environments.

Water Pumps are primarily classified into single-stage single-suction centrifugal pumps (end-suction pumps) and single-stage double-suction centrifugal pumps (split-case pumps) based on their structural design. These pumps feature well-engineered structures, convenient maintenance, and stable performance, making them suitable for conveying clean water and media with properties similar to clean water in various operating conditions. Single-stage single-suction centrifugal pumps (end-suction pumps) adopt a back pull-out structure, allowing maintenance and inspection without dismantling the pipeline. The centerline discharge combined with foot support helps resist pipeline deformation. Equipped with a patented hydraulic model, these pumps offer high efficiency and reduced operating costs. Single-stage double-suction centrifugal pumps (split-case pumps) use a horizontal split-case design, with the pump casing divided into upper and lower halves. This structure simplifies disassembly and maintenance, significantly reducing maintenance costs. The double-suction impeller draws liquid from both sides, providing large flow capacity and excellent hydraulic performance. It can also automatically balance axial force, resulting in smoother and more stable operation. Key component materials are available in multiple options, and the core components are sourced from internationally recognized brands. Mechanical seals or packing seals can be selected according to specific operating conditions, achieving a balanced combination of efficiency, reliability, and service life. These pumps are suitable for a wide range of applications, including industrial water supply and municipal water distribution systems.
