SZX Horizontal Self-priming Pump

SZX series self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, convenient maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install the bottom valve in the pipeline, and only need to keep the quantitative liquid in the pump body before work, thus simplifying the pipeline system and improving the working conditions.

Product Introduction

1. Self-Priming centrifugal pump is suitable for urban environmental protection, construction, fire protection, chemical industry, pharmacy, dye, printing and dyeing, brewing, electric power, electroplating, papermaking, petroleum, mining, equipment cooling, tanker unloading, etc.
2. It is suitable for clear water, sea water, chemical medium liquid with acid and alkalinity, and slurry with general paste (medium viscosity ≤ 100 centipedes, solid content up to 30% or less).
3. The rocker-type nozzle is installed, and the water can be washed into the air and scattered into small raindrops for spraying. It is a good machine for farms, nurseries, orchards and tea gardens.
4. Self-Priming centrifugal pump can be used with any type and specification of filter press to send the slurry to the filter for pressure filtration.

Self-Priming Centrifugal Pump Features

No External Equipment Required: The self-priming centrifugal pump operates without a foot valve, priming water, or other external devices. It automatically primes itself at startup, simplifying installation and maintenance.
Strong Self-Priming Capability: The pump can automatically draw liquid from the source, even in low or deep well conditions. Its strong self-priming ability makes it ideal for scenarios where the liquid source is below the pump or in challenging environments.
Versatility in Liquids: It can efficiently handle a wide range of liquids, including clean water, wastewater, liquids with gases, and both low and high-viscosity liquids. It excels in handling liquids with bubbles, foam, or minor impurities.
Reduced Maintenance Costs: The absence of foot valves, priming systems, and other auxiliary equipment significantly reduces installation and maintenance costs while streamlining operational processes.
Reliable and Durable: Made from high-quality corrosion-resistant and wear-resistant materials, the self-priming centrifugal pump is built for long-lasting, reliable operation, even under harsh conditions.
Quick Air Evacuation: The pump quickly expels air from the pump chamber at startup, restoring the self-priming function rapidly. This reduces startup time and enhances operational efficiency.

Self-Priming Centrifugal Pump Applications

Self-priming centrifugal pumps are widely used in fluid transfer, drainage, and sewage applications. They are especially suited for the following scenarios:
Water and Wastewater Treatment: Self-priming centrifugal pumps are ideal for pumping wastewater, recycled water, and clean water, especially in low-water-source environments such as ponds or rivers. They provide efficient, reliable transfer from lower water levels.
Agricultural Irrigation and Drainage: The pump is capable of quickly drawing water from underground or reservoirs for irrigation, making it perfect for agricultural fields and large-scale irrigation systems.
Construction Site Water Supply and Drainage: These pumps are well-suited for large buildings, high-rise construction, and underground projects, where substantial water supply and drainage are needed. They can efficiently pump water from low levels to meet the daily demands of construction sites.
Chemical and Petrochemical Industries: The self-priming pump is capable of transferring corrosive liquids, foamy liquids, and liquids with minor impurities. It is widely used in industries like chemicals, petrochemicals, and pharmaceuticals, where acids, alkalis, oils, solvents, and other substances need to be pumped.
Firefighting Systems: In firefighting pump systems, the self-priming centrifugal pump can be used to efficiently extract water, ensuring a stable supply for emergency response and fire suppression.
Industrial Liquid Transfer: In chemical processing, pharmaceuticals, and food manufacturing, the self-priming centrifugal pump is ideal for transferring chemical solutions, slurries, and other liquids.

Product Advantages

Powerful Self-Priming: The self-priming centrifugal pump uses advanced air discharge designs to rapidly evacuate air from the pump chamber and restore the negative pressure, ensuring continuous, efficient operation without manual intervention.
Energy Efficient: With an efficient impeller design, the pump delivers higher flow rates with lower energy consumption, reducing overall operating costs.
Simple Structure, Easy Maintenance: Unlike traditional pumps, the self-priming pump does not require a foot valve, suction pipe, or additional components, making installation straightforward. It also reduces the need for specialized technical support during maintenance.
Durable Construction: The pump body is made from high-quality cast iron, stainless steel, and alloys, offering excellent corrosion resistance, wear resistance, and oxidation protection. It is suitable for various harsh operating conditions and ensures a longer service life.
Wide Applicability: Whether for clean water, wastewater, chemical solutions, or liquids with impurities, the self-priming centrifugal pump performs excellently across various industries.
