Horizontal Self Priming Pump | Industrial Self Priming Centrifugal Pump

The HNYB horizontal self-priming pump is a single-stage centrifugal pump that automatically draws liquid without a foot valve or external priming system. Thanks to its horizontal structure and advanced self-priming chamber design, this pump is reliable, easy to install, and offers excellent performance, suitable for conveying clean water, wastewater, and liquids containing suspended solids.
Its compact structure and strong self-priming capability make it suitable for applications such as municipal drainage, industrial wastewater treatment, agricultural irrigation, emergency drainage, and construction site pumping. Depending on the installation conditions, the self-priming height of this pump can typically reach 5 meters.

Products application

Municipal Sewage & Wastewater Networks: Main lift stations, underground bypass pumping, and storm water dewatering infrastructure.
Industrial Effluent Logistics: Pumping corrosive, fiber-heavy industrial wastewater out of textile mills, food processing plants, and tanneries.
Construction Site & Emergency Dewatering: Rapid evacuation of mud-heavy trench water, flooded basement vaults, and high-solid construction runoff.
Product Features
1. Easy to start: Horizontal self-priming pumps are able to start automatically without the need for an external priming system. This is because they are equipped with a built-in vacuum system that draws water from the water source and creates the pressure required to start pumping.
2. Versatility: Horizontal self-priming pumps are used in a wide range of applications, both above and below ground. They can handle a variety of liquids, including water, chemicals, and semi-solid substances.
3. Efficiency: Horizontal self-priming pumps are highly efficient and can pump faster and more efficiently than traditional pumps. This is because they do not require any manual priming, which saves time and reduces labor costs.
4. Cost-effective: Horizontal self-priming pumps are also more cost-effective than traditional pumps because they are less maintenance-intensive and can operate without expensive external priming systems.
5. Reduced downtime: Horizontal self-priming pumps are less likely to shut down due to water priming problems because they can automatically prime and continue pumping even if the pump temporarily experiences air blocking. This reduces service interruptions and increases uptime.
