Auto Dry Prime Pumps
Auto dry-prime pumps deliver reliable self-priming performance using automated priming technology — ensuring the pump starts and maintains prime without operator intervention.
Built for remote sites, intermittent operation, and applications with fluctuating suction lift, they provide dependable operation in civil, construction, wastewater and mining environments.
- Automated dry-prime capability for unattended or remote operation
- Dependable priming on long suction lines or variable water levels
- Compatible with diesel, electric, hydraulic & PTO pump configurations
ldeal for civil works, construction dewatering, wastewater bypass, stormwater management & remote mining where reliable priming without supervision is critical.
Compact, mechanically driven priming solution ideal for intermittent operation and remote sites where reliability is essential.
- Rugged mechanical diaphragm generates strong suction for dependable priming.
- Performs consistently on long suction lines or uneven water levels.
- Low-maintenance design with easily serviceable diaphragm components.
- Ideal for unattended operation, standby pumps, and emergency bypass systems.

FAQ's
for Auto Dry Prime Pumps
-
What is the difference between diaphragm and compressor-venturi priming?
Diaphragm priming is mechanically driven and ideal for remote or intermittent operation. Venturi priming uses compressed air and is significantly faster, making it suitable for larger pumps and frequent cycling.
-
Can Auto Dry Prime systems run without water in the suction line?
Yes. Both systems are designed to automatically evacuate air and prepare the pump for operation without manual intervention, preventing dry-run damage during startup.
-
Are these priming systems compatible with any pump type?
Yes. They can be paired with self-priming, centrifugal, high-pressure, or trash pumps, depending on the duty requirements.
-
Do they require regular maintenance?
Diaphragm systems require periodic diaphragm inspection and replacement. Venturi systems have fewer wear components and typically require only routine compressor servicing.
-
Can they be mounted on trailers, skids, or static frames?
Yes — both priming technologies are compatible with all standard Allflo mounting configurations.
