Related Centrifugal Pumps
If a self-priming pump is not the correct fit for your application, Rapid can help assess other centrifugal pump configurations and related pump types.
End-suction pumps are practical, versatile centrifugal pumps used for water transfer, irrigation, industrial utility duties and general fluid movement.
Split case pumps are often used for higher-flow applications where durability, efficiency and easier maintenance access are important.
Vertical spindle pumps are suited to sump, tank, pit and vertical installation requirements where the pump arrangement needs to operate from below or within a liquid source.
Piston pumps are positive displacement pumps suited to certain pressure or controlled-flow applications.
Diaphragm pumps are positive displacement pumps often used for abrasive, corrosive, viscous or difficult fluids.
Self-Priming Pumps for Practical Transfer, Drainage and Dewatering
Self-priming pumps are designed for applications where the pump must draw liquid from below the pump level or where manual priming would be impractical. Under suitable conditions, a self-priming pump can evacuate air from the suction line and re-establish pumping after the casing has been initially filled.
This makes self-priming pumps useful for dewatering, drainage, wastewater transfer, agriculture, construction, temporary site pumping, tank transfer and industrial support duties.
Rapid manufactures and supports self-priming pump solutions for clients who need reliable operation in practical field and plant environments. Our team helps assess the suction conditions, fluid type, duty point and installation requirements before recommending the correct pump solution.

These pumps are often used where pumping conditions change, where the liquid source sits below the pump, or where manual priming would slow down operations.
Suitable for Dewatering and Drainage
Self-priming pumps are commonly used in drainage, dewatering, transfer and site-based applications where operational flexibility is required.
Application-Specific Selection
Correct pump selection depends on suction lift, flow rate, head, fluid characteristics, solids content, temperature and installation conditions.
Local Manufacturing Support
Rapid’s local manufacturing capability supports technical communication, practical configuration support and greater accountability.
Workshop and Spares Backup
Rapid supports self-priming pumps with workshop capability, repairs, refurbishment, spare parts assistance and aftermarket support where appropriate.

Industries That Use Self-Priming Pumps
Rapid supports self-priming pump requirements across industries and sites where fluid needs to be moved reliably from challenging or changing source conditions.
Our pump solutions support:
Self-Priming Pump Applications
Self-priming pumps are used in applications where suction lift, priming convenience, drainage or practical site operation are important.
Used to remove water from construction areas, pits, sumps, excavations, low-lying sites and temporary work areas.
Suitable for moving water from areas where fluid collects and needs to be transferred away from the working environment.
May be used for selected wastewater, effluent or dirty water applications depending on the solids content, fluid composition and pump configuration.
Self-priming pumps can support water transfer, drainage, irrigation support and farm utility applications.
Used in industrial environments for transfer duties where suction lift or priming convenience is required.
Suitable for moving liquid from tanks, reservoirs, containers or lower-level sources where the pump is positioned above the liquid level.
Practical for site-based pumping where conditions may change and ease of operation is important.
Rapid can assist where an existing self-priming pump needs to be replaced, repaired, assessed or upgraded.
