The Roto-Jet pump is a cutting-edge, high-pressure, single-stage centrifugal pump that utilizes advanced pitot tube technology to handle demanding low-flow, high-head applications. Designed to operate on the pitot tube pump concept, this unique “backward pump” has earned a global reputation for its reliability, robustness, and exceptional performance across multiple industries.
No External Lube System Required
One of the standout features of the Roto-Jet pump is its ability to operate without an external lubrication system. This design choice not only reduces maintenance costs and complexity but also enhances the pump’s overall efficiency. By eliminating the need for an external lube system, the Roto-Jet pump minimizes the risk of leaks, contamination, and other maintenance-related issues, making it an attractive option for a wide range of applications.
Durable Design with No Wear Rings or Close Running Clearances
The Roto-Jet pump’s design philosophy prioritizes durability and longevity. Unlike traditional centrifugal pumps, the Roto-Jet is engineered without wear rings or close running clearances. This innovative approach increases the pump’s resistance to wear and tear, reducing maintenance requirements and extending its overall lifespan. By eliminating these components, the Roto-Jet pump can maintain its high level of performance and reliability even in the most demanding operating environments.
Robust Design Handles Process Upsets with Ease
The Roto-Jet pump’s robust design is a key factor in its ability to withstand process upsets without failure. This resilience is achieved through the careful engineering of the pump’s internal components and the overall structural integrity of the design. Even in the face of unexpected changes in the process conditions, the Roto-Jet pump can continue to operate reliably, ensuring uninterrupted performance and minimizing the risk of costly downtime.
Pulsation-Free Flow Across the Entire Head-Flow Curve
One of the Roto-Jet pump’s most impressive features is its ability to deliver pulsation-free flow across the entire head-flow curve. This characteristic is particularly valuable in applications where downstream equipment, such as valves or instrumentation, can be sensitive to flow fluctuations. By maintaining a consistent, smooth flow, the Roto-Jet pump reduces wear and tear on these components, improving overall process efficiency and reliability.
Optimized Hydraulic Efficiency Reduces Life Cycle Costs
The Roto-Jet pump’s design prioritizes hydraulic efficiency, which directly translates to reduced life cycle costs. By optimizing the pump’s hydraulic performance, the Roto-Jet can achieve higher levels of energy efficiency, lowering operating expenses and contributing to a more sustainable and cost-effective process. This focus on efficiency not only benefits the bottom line but also aligns with the growing emphasis on environmental responsibility in many industries.
Process Seals Exposed Only to Suction Pressure for Maximum Seal Life
The Roto-Jet pump’s unique design ensures that the process seals are exposed only to the suction pressure, rather than the full discharge pressure. This design feature maximizes the seal life, as the seals are not subjected to the higher pressures typically encountered in other pump types. By extending the seal life, the Roto-Jet pump reduces maintenance costs and downtime, further enhancing its overall value proposition.
High Heads Achieved in a Single Stage at Low Operating Speeds
Compared to other low-flow, high-head pump technologies, the Roto-Jet pump stands out for its ability to achieve high heads in a single stage while operating at relatively low speeds. This characteristic translates to reduced energy consumption and improved process efficiency, as the pump can deliver the required performance without the need for multi-stage configurations or excessively high rotational speeds.
Broad Operating Range Designed to Avoid Damaging Hydraulic Forces
The Roto-Jet pump is specifically engineered to achieve a broad operating range without creating damaging hydraulic forces within the pump. This design feature is particularly beneficial in severe low-flow, high-head process applications, where the pump must be able to handle a wide range of operating conditions without compromising its performance or reliability.
Stationary Pitot Tube Facilitates Rotor Venting During Start-Up
The Roto-Jet pump’s pitot tube is strategically positioned in the 12 o’clock position, which facilitates the venting of the rotor during start-up. This design element helps to ensure smooth and reliable operation, even in the most challenging low-flow, high-head applications, further contributing to the pump’s overall robustness and longevity.
By combining these advanced features and design principles, the Roto-Jet pump has established itself as a premier choice for demanding low-flow, high-head applications across a variety of industries, including oil and gas, petrochemical, power generation, and water treatment, among others. Its exceptional performance, reliability, and efficiency make it a valuable asset in any process where high-pressure, single-stage centrifugal pumping is required.
