WFB Vertical self priming centrifugal transfer pump

A compact vertical centrifugal transfer pump engineered for reliable self-priming operation without mechanical shaft seals or traditional packing. The pump uses a multi-face interlock centrifugal sealing device and vacuum-pump-inspired self-priming principle so it can be primed once and maintain dependable self-priming performance during continuous service.

Key features

• Seal-less, self-priming design: eliminates packing and mechanical seal leakage and their maintenance needs; ideal as a replacement for long-shaft submerged and submersible pumps.
• Durable construction options: available in cast iron, 321, 304, 316, 316L, A3 and enhanced polypropylene (PP) to suit corrosive or hygienic applications.
• Long service life: friction-free sealing during operation reduces wear — manufacturer claims substantially longer service life versus comparable products.
• Stable priming and control: vacuum-principle priming combined with an electric air control valve provides consistent, single-fill self-priming behavior.
• Easy installation and maintenance: vertical configuration with small footprint, low vibration and noise, flexible mobility, simple disassembly, and no requirement to bolt pump feet to the foundation in many installations.
• Automation-ready: integrated automatic control capabilities make the pump suitable for high-tech, fully automated systems.

Typical applications

Suitable for transfer, circulation and process duties across electronics, power generation, chemical processing, metallurgy, pharmaceuticals, food and beverage, electroplating, environmental protection and wastewater treatment, fire protection, municipal water treatment, textile processing, mining and mineral processing, and civil construction.

Selection notes

• Choose construction material based on fluid chemistry and temperature requirements.
• Confirm model and performance curves (flow, head, motor power) with supplier to match process conditions and ensure correct pump sizing and drive configuration.

This pump is best suited for industrial users seeking a low-maintenance, seal-less vertical self-priming solution for liquid transfer where space, reliability and automation integration are priorities.
