Two Stage Pumps
Our independently developed two-stage filter feed pumps are engineered for demanding filter press applications, delivering stable high-pressure performance even at low flowrates. In laboratory conditions, the minimum flowrate reaches 20 m³/h (approx. 88 GPM), while maximum throughput can exceed 1000 m³/h (approx. 4,403 GPM). In addition, the maximum discharge pressure is above 20 bar (approx. 290 psi) — significantly higher than that of conventional single-stage pumps — enabling the formation of drier and more compact filter cakes, thus improving solid-liquid separation efficiency and operational economics.

Structure Features
Sunlike has pioneered three major series of two-stage feed pumps:
SYAX Series — A breakthrough product line that achieved iconic success in the Chinese market and set a performance benchmark in the filter press industry;
SYB Series — Tailored for small-flow, high-pressure duty points, filling an important market gap;
SYE Series — Designed for ultra-high pressure and extreme total head applications, delivering exceptional filtration performance.

Thanks to continuous innovation and reliable field performance, Sunlike two-stage pumps have become long-term strategic supply partners to leading filter press manufacturers such as Jingjin, Dazhang, and Zhongda Bright.
Advantages Of Two Stage Pumps
Two-stage pumps deliver higher efficiency and performance than single-stage pumps, especially in systems with fluctuating demand. Unlike single-stage pumps that run at full capacity continuously, two-stage pumps can modulate output, reducing energy consumption and wear. This makes them ideal for applications requiring variable flow or precise pressure control, such as industrial processes and filtration systems.
Single-stage pumps, while simpler and more cost-effective for constant-flow applications, lack operational flexibility and may become inefficient when flow or pressure requirements change.
In short, two-stage pumps provide better efficiency, control, and adaptability, while single-stage pumps suit stable, lower-complexity systems.

Common Problem
1. What is the main use of slurry pump?
Slurry pump is mainly used to transport liquid containing solid particles, widely used in mining, metallurgy, coal, electric power, chemical, building materials and environmental protection and other industries.
2. What is the working principle of the slurry pump?
The slurry pump inhales the slurry from the suction inlet of the pump body through the centrifugal force generated by the rotation of the impeller, and the slurry is discharged from the discharge outlet of the pump body through the diversion of the pump shell.
3. How to choose the right slurry pump?
The selection of slurry pump needs to consider the following factors:
The physical and chemical properties of the medium, such as temperature, viscosity, corrosion, etc
The size and concentration of solid particles
Required flow and head
Pump material and structure
4. What are the precautions for the maintenance and maintenance of slurry pump?
Check the wear condition of impeller, pump housing and shaft seal regularly, and replace the worn parts in time
Keep pump body and pipe clean to prevent impurities from entering pump body
Check and replace lubricating oil regularly to ensure the normal operation of bearings
Check the coupling of the motor and pump regularly to ensure that the connection is secure
5. What are the common faults and treatment methods of slurry pump?
The pump does not produce pulp or insufficient pulp: check whether the suction inlet is blocked, whether there is air in the pump body, and whether the impeller is worn.
Pump body vibration or noise: check whether the pump shaft is bent, the impeller is balanced, and the bearing is damaged.
Seal failure, leakage: check whether the seal wear, replace the seal in time.
