OGZB Structural Features (I): Core Structure
OGZB Structural Features (II): Core Technologies
▶Dual water absorption design
The dual-side water inlet impeller ensures a uniform distribution of inlet flow velocity, providing excellent cavitation performance; The axial force is fully self-balanced, eliminating the need for additional thrust bearings, and the mechanical seal operates in a stable environment.
▶Labyrinth-style self-priming seal
The unique dual-flow channel labyrinth seal structure allows the liquid retained inside the pump to achieve self-priming, enabling one-time drainage and lifetime self-priming; Eliminate the electric air control valve and complex piping of traditional self-priming pumps.
▶Self-cooling device
It adopts patented self-cooling technology, allowing the pump to cool its mechanical seal and bearing components during operation without the need for external cooling water pipelines, thereby simplifying installation and reducing energy consumption.
▶Wear-resistant material system
The flow components are fully made of 2Cr13 wear-resistant stainless steel and QT500 integral casting process, suitable for solid-containing media and long-term continuous operation conditions.
OGZB Retrofit Application Advantages:
WFB seal-less or long-shaft vertical pumps in cyclone/slag pits run at ~50% efficiency with high energy use, cavitation and frequent repairs; vacuum-assisted pumps leak in scale/oil-laden media and endanger pit safety. After years of R&D with research institutes, we developed the latest high-efficiency double-suction self-priming pump.
The OGZB retains the safety, reliability, easy installation and small footprint of old WFB pumps while eliminating their low efficiency, high energy consumption and poor cavitation performance at high flow and high temperature.
