OVELL Flap Valve Diaphragm Pump is designed for transferring high-viscosity fluids, slurries, solids-containing liquids and media with larger particles. Compared with conventional ball valve AODD pumps, the flap valve design provides a larger and less restricted flow path, helping reduce blockage when handling difficult industrial fluids.
Large Particle Handling: The flap valve structure provides a wide flow passage and is suitable for fluids containing larger solids and suspended particles.
High-Viscosity Fluid Transfer: Designed for pumping viscous liquids, slurries, pastes and other difficult-to-transfer process media.
Low Shear Operation: The air operated diaphragm pump design provides gentle fluid handling and helps reduce excessive agitation of sensitive materials.
Self-Priming Capability: Suitable for applications where the pump is installed above the fluid level or where suction conditions vary.
Dry-Running Capability: The AODD operating principle allows temporary dry running without mechanical seal damage.
Air Operated Design: Powered by compressed air without an electric motor at the pump, supporting use in a wide range of industrial environments.
Reduced Clogging Risk: The flap valve configuration helps solids pass through the pump more easily than conventional ball-check designs.
Easy Maintenance: Simple pneumatic operation and accessible valve components help simplify inspection, cleaning and routine servicing.
