Self-priming non-clogging sewage drainage pump for waste liquids
ZW Series self-priming non clogging sewage pump is an high-efficiency pump that combines self-priming function and non-clogging sewage drainage.
ZW self-priming pump adopts an axial reflux external mixing design, which significantly increases its self-priming height. Compared with traditional self-priming pumps, its self-priming height can reach more than 5 meters. This feature enables ZW self-priming pumps to work more effectively in complex terrains or operating conditions that require a longer suction stroke, reducing efficiency losses caused by insufficient suction stroke.
Combination of closed impeller and semi open impeller
The impeller design of ZW self-priming pump is unique, combining the efficiency of a closed impeller with the anti-blocking ability of a semi open impeller. Closed impellers can provide higher head and efficiency, while semi open impellers can reduce the risk of blockage by passing larger particles and fibers.
The impeller adopts a unique open design, allowing it to pass solid particles with a diameter of 60% of the pump diameter and fiber materials with a length of 5 times the diameter. This design not only improves the discharge capacity of the pump, but also reduces the possibility of blockage, ensuring long-term stability during operation.
Excellent hydraulic model, the efficiency of ZW self-priming pump is 3-5% higher than that of general self-priming pump. Efficient and energy-saving not only reduces operating costs, but also reduces energy consumption, meeting modern environmental requirements. In addition, some models also adopt variable frequency controllers to further achieve energy-saving effects.
Suitable for various complex working environments, including liquid extraction containing large solid particles and long fiber impurities. It can play an important role in fields such as electricity, mining, petrochemicals, and steel, especially in the treatment of wastewater containing solid-liquid mixtures.
High quality mechanical seals
In order to ensure long-term stability, ZW self-priming pump adopts high-quality mechanical sealing device. This not only effectively prevents liquid leakage, but also reduces the risk of contamination caused by leakage, ensuring a clean working environment.
