Recently, several units of HIGHPUMP hose pumps ordered by a power plant customer were officially loaded and shipped after completing factory quality inspection and packaging. These hose pumps are used for conveying lime slurry in the new power plant, effectively ensuring stable operation and supporting environmental protection.
Lime slurry plays an indispensable role in processes such as desulfurization and water treatment in power plants. It is corrosive to some extent, may contain fine lime particles, and is prone to sedimentation and crystallization, leading to significant wear and corrosion on pumps. Traditional pumps often face challenges such as leakage, clogging, and frequent replacement of vulnerable parts when conveying lime slurry, resulting in high maintenance costs and environmental pollution.
Advantages of Hose Pumps
Corrosion and Abrasion Resistance: The medium only comes into contact with the corrosion- and abrasion-resistant inner wall of the hose, not the pump body, and the pump operates at low speeds. The hose is made of special composite rubber material, offering excellent resistance to both corrosion and abrasion.
No Mechanical Seals or Packing Seals: Hose pumps rely on the elastic deformation of the hose to suction and convey the medium, eliminating the need for mechanical or packing seals. This fundamentally prevents leakage, ensuring production safety and environmental protection.
No Check Valves: The absence of check valves avoids clogging issues.
Reversible Operation: The pump can reverse, making it easy to empty and clean.
High Self-Priming Capability: With a self-priming height of up to 9.5 meters, it can handle slurries with high solid content.
Metering Capability with Stable Flow: By precisely controlling the compression frequency of the hose, the pump achieves stable flow output with an accuracy of up to ±1%.
Intelligent Control: Integrated pressure monitoring and speed adjustment functions enable seamless connection with the power plant's DCS system, offering more convenient operation and faster response.
Easy Maintenance: Maintenance is simple and efficient, requiring only the replacement of the hose.
