Self-priming pump: Configured in a special construction to achieve higher self-priming capacity and shorter pumping time.
Additional Foot Valve is not necessary. It performs exhaust pumping when first changed to reduce the trouble of pouring water.
Coaxial Type: Designed in direct coaxial construction. Lighter, less space and easier for installation.
Semi-open impeller Design: Suitable for pumping liquid containing particles, longer fiber objects or mud (in case of clean fluid, it can be set to sealed impeller model).
