Introduction: The Series of Vacuum Prime Assist pumps represents the pinnacle of reliability for critical fluid transfer and dewatering tasks. This system is designed for true unattended operation, using an integrated vacuum pump to automatically prime and re-prime itself on demand. It is the definitive choice for applications where a loss of prime is common or where pump failure is not an option, providing unmatched performance in handling air, water, or a mix of both without risk of damage.
Operating Principle: The “prime assist” system is a fully automatic, dry-priming design. Unlike standard pumps that use the main impeller to slowly pull a prime, this system uses a dedicated vacuum pump to rapidly evacuate all air from the suction line and pump casing. A float-switch mechanism inside an air/water separation tank detects once the pump is completely flooded with water. Only then does it engage the main pump to begin pumping at full capacity, while the vacuum system shuts off. If the pump begins to draw air, the system automatically re-engages the vacuum pump to maintain prime, ensuring continuous and trouble-free operation.
Key Features & Benefits:
- Unattended 24/7 Operation: The fully automatic priming and re-priming system, managed by the internal float switch, allows the pump to run and adapt to changing conditions without operator intervention.
- Dry-Run Prevention: A key benefit of this system is that it protects the main pump’s expensive mechanical seal from damage, as the pump will never run dry. The vacuum system ensures it is always flooded with liquid before operating.
- Fastest Priming in its Class: The powerful vacuum pump can achieve a full prime in seconds, not minutes, making it ideal for emergency response and applications where rapid dewatering is essential.
- Handles Difficult Suction Conditions: Excels in situations with high suction lifts, long suction lines, or where the pump is required to “snore” (pump a mixture of air and water) to completely dewater an area.
- Versatile and Mobile: Commonly mounted on heavy-duty skids or road-worthy trailers with either diesel engines or electric motors, providing a powerful pumping solution that can be deployed anywhere.
Common Applications:
- Sewer bypass pumping during municipal pipe repair and maintenance.
- Critical dewatering for construction sites, tunnels, and cofferdams.
- Wellpoint dewatering and ground stabilization.
- Emergency flood relief and large-scale water transfer.
- Tank cleaning and fluid transfer in industrial and mining operations.
