Advanced Pitot Tube Pump Technology
The Reliable, Cost-Effective Alternative to Roto-Jet® Pumps. High Pressure. Low Flow. Pulsation Free.
Our Solution
Why Choose Our Pitot Tube Pumps?
For decades, industries have relied on pitot tube technology for high-pressure, low-flow applications. Weiming provides a direct drop-in replacement and high-performance alternative to traditional Roto-jet pumps, offering the same reliability at a more competitive price point.
Our pumps utilize a stationary pick-up tube (pitot tube) within a rotating casing, generating high pressure without the complexity of multi-stage centrifugal pumps or the pulsation of reciprocating pumps.
- Direct Roto-jet® Equivalent Performance
- Simpler Design, Lower Maintenance Cost
- Wide Operating Range & Flexibility
Engineered for Efficiency
Simple Construction
With only two basic working parts—a rotating case and a stationary pick-up tube—seal failure and mechanical wear are significantly minimized compared to complex multistage pumps.
Pulsation-Free Flow
Delivers smooth, steady flow ideal for sensitive applications like Reverse Osmosis (RO) and boiler feed systems, eliminating the need for pulsation dampeners.
Easy Maintenance
The internal assembly can be replaced quickly without disconnecting piping or the motor, dramatically reducing downtime in critical production lines.
Technical Specifications
High performance meets durability.
