Quantity

WFB unsealed self-priming pumps have become an ideal choice in the fields of chemical engineering, environmental protection, fire protection, etc. due to their leak free sealing technology, strong self-priming ability, high efficiency and energy saving, and vertical structure. As a seal pump, it greatly solves the leakage problem of traditional pumps; As a vertical centrifugal pump, it saves space through its vertical design; As an alternative to vertical water well pumps, it can directly extract water from deep wells. Whether transporting hazardous media or ordinary liquids, WFB sealless pump can provide efficient and reliable solutions.

Product Features

Leak Free Design

No shaft seal structure: completely eliminates the risk of leakage, suitable for the transportation of flammable, explosive, toxic or valuable liquids.
Environmental protection and safety: To prevent medium leakage from causing harm to the environment and personnel.

Automatic Control Function

Automatic control: It can be used in conjunction with high-tech fields and highly automated systems to achieve remote monitoring and fault warning.
Shutdown sealing: Install a shutdown sealing device to ensure that the pump can maintain a sealed state even when stopped.

Low Noise, low Vibration

Smooth operation: low vibration and noise, suitable for noise sensitive occasions.

Products Advantages

No Sealing Technology

Thoroughly solve the leakage problem: adopt a rotating seal in the form of a secondary impeller, replacing traditional packing seals or mechanical seals, greatly reducing the phenomenon of"running, emitting, dripping, and leaking", especially suitable for high-risk areas, small spaces, and inconvenient installations.

Strong Self-Priming Ability

One drainage, lifelong self-priming: Based on the principle of transplanting a vacuum pump, an electric air control valve is used to achieve rapid self-priming without the need for frequent pumping, making it particularly suitable for frequent starting situations.
Large self-priming depth: self-priming depth can reach 2.5-7 meters, suitable for suction of deep wells or low-level water sources

Application Scenarios

Chemical and Pharmaceutical Industry
Transport acids, alkalis, oils, rare and valuable liquids, venoms, volatile liquids, etc. to ensure no leakage and guarantee production safety.
Environmental Protection and Water Treatment
Suitable for conveying media containing particles or high viscosity, such as sewage treatment, circulating water equipment matching, and filter matching.
Petroleum and Mining
Extract vertical water well pumps, mine drainage, oil transportation, etc., to adapt to complex working conditions.
Fire and Municipal Affairs
Ensure efficient and stable self-priming performance for fire water supply, municipal water purification, rainwater discharge, etc.

Service Assurance

Precise Demand Matching

Free on-site condition assessment with customized solutions (flow rate, head, and piping configurations precisely tailored to operational needs).

Rapid Delivery Response

Standardized modular design shortens delivery cycles by 30%, with priority processing for emergency project requirements.

Flexible Warranty Policy

1-year warranty for the entire machine, extended to 2 years for non-standard customized components, complemented by scheduled proactive maintenance and a 2-hour fault response guarantee.

In the field of industrial fluid treatment, traditional pump bodies often face increased equipment maintenance costs and environmental pollution risks due to mechanical seal wear, medium leakage, and other issues. The Sealess Self Control Self Imbibe Pump, with its revolutionary sealing technology and self-priming function, is gradually becoming the preferred solution for industries such as chemical, pharmaceutical, and environmental protection. This type of pump is driven by magnetic force or innovative sealing structure, combined with the compact design and efficient head characteristics of a vertical centrifugal pump. Whether dealing with highly corrosive media, high viscosity fluids, or responding to rapid start stop requirements in complex working conditions, unsealed self suction pumps demonstrate excellent adaptability and reliability. The following are the core parameters of PWS seals pump

As an innovative product that combines sealless pump and vertical centrifugal pump technology, the PWS Sealess Self Control Self Absorption Pump's core component design fully embodies the characteristics of safety and efficiency. The pump adopts a magnetic transmission instead of traditional mechanical seals, completely eliminating the risk of medium leakage through the static sealing structure of the inner and outer magnetic rotors. Its isolation sleeve is mostly made of corrosion-resistant metal or high-strength engineering plastic, ensuring long-term stability under harsh working conditions such as chemical and pharmaceutical industries. The pump body adopts a vertical structure, with the impeller and flow guiding components arranged vertically. Combined with an optimized self-priming chamber, it can achieve rapid self-priming without external water intake conditions, especially suitable for intermittent operation scenarios. Key components such as shaft sleeves and bearings are made of wear-resistant engineering ceramics or silicon carbide materials, relying on the conveying medium to achieve self-lubricating, which not only reduces maintenance costs but also improves the equipment's adaptability to high viscosity or particle containing media. In addition, the motor of the pump is directly connected to the pump body through an elastic coupling, reducing transmission losses. At the same time, the vertical layout significantly saves installation space, making it an ideal choice in fields such as municipal sewage and environmental engineering.

The Sealless Self-Control Self-Imbibe Pump is an advanced vertical water well pump designed for efficient and maintenance-free operation. Its innovative sealless design eliminates leakage risks, while the self-control and self-imbibe features ensure automatic fluid regulation and optimal suction performance without manual intervention. Ideal for deep-well applications, this vertical pump is engineered for durability, energy efficiency, and reliable water extraction in agricultural, industrial, or residential settings. Easy to install, it minimizes downtime and maximizes productivity in demanding environments.

The performance curve of the Sealless Self-Control Self-Imbibe Pump highlights its efficiency as a sealless pump and vertical centrifugal pump, showcasing flow rate (Q), head (H), power consumption (P), and efficiency (η) across various operating conditions. Designed for deep-well applications, its sealless construction ensures zero leakage, while the vertical centrifugal pump configuration delivers high-pressure water lifting with minimal energy loss. The curve demonstrates stable performance under variable loads, with the self-imbibe feature enabling reliable self-priming even at low suction pressures. Ideal for industrial, agricultural, or municipal water systems, this pump combines durability with optimized hydraulics for consistent operation.
