The other key aspect of a mechanical pump seal is how to maintain the seal. Springs (single or multiple), a metal bellows or just compressed elastomers are used to provide the needed energy to keep pressing the seal faces together.It is important to review how a pump mechanical seal works. First, its main components are the rotating and stationary face rings that form the primary seal (Image 1). The face rings have flat, precision-smooth contact surfaces that are held in tension against each other by mechanical springs. The rotating . See more

The centrifugal pump had a 6-in. impeller and the regenerative turbine a 4.25-in. impeller, each running 1750 rpm. Fig. 6 shows the high head obtained with a small diameter impeller. It also shows the pump's wide operating range.
The VitalFlow™ ECMO system provides control of blood pumping through an extracorporeal membrane oxygenation (ECMO) circuit. Within this system, the centrifugal ECMO pump plays a crucial role in maintaining adequate blood flow and oxygenation levels in critically ill patients. This article will delve into the various aspects of the centrifugal ECMO pump, including its function, advantages over roller pumps, and its role in ECMO protocols.
The CentriMag blood pump functions as: Part of an ECMO †† circuit for periods > 6 hours;
ECMO Flow vs Sweep
In ECMO circuits, the terms "flow" and "sweep" are commonly used to describe the movement of blood through the system. Flow refers to the rate at which blood is pumped through the circuit, typically measured in liters per minute. Sweep, on the other hand, refers to the rate at which gas (usually oxygen) is delivered to the oxygenator to facilitate gas exchange. The centrifugal ECMO pump plays a key role in controlling flow rates, ensuring adequate oxygenation and carbon dioxide removal.
ECMO Indications
ECMO is indicated in patients with severe respiratory or cardiac failure who are unable to maintain adequate oxygen levels despite conventional therapies. Common indications for ECMO include acute respiratory distress syndrome (ARDS), cardiogenic shock, and post-cardiotomy syndrome. The centrifugal ECMO pump is essential in providing circulatory support and oxygenation in these critical conditions.
ECMO Protocol
The ECMO protocol outlines the steps and parameters for initiating, managing, and weaning patients off ECMO support. The use of a centrifugal ECMO pump in the circuit allows for precise control of blood flow and pressure, optimizing oxygen delivery and carbon dioxide removal. Close monitoring of patient parameters, including oxygen saturation and arterial blood gases, is essential in following the ECMO protocol effectively.
Roller Pump vs Centrifugal ECMO
Traditionally, roller pumps have been used in ECMO circuits to provide blood flow. However, centrifugal ECMO pumps offer several advantages over roller pumps. Centrifugal pumps are more compact, have fewer moving parts, and provide smoother blood flow, reducing the risk of hemolysis and clot formation. Additionally, centrifugal pumps can generate higher flow rates, making them suitable for a wider range of patient conditions.
Centrifugal vs Roller Pump
The choice between centrifugal and roller pumps in ECMO circuits depends on various factors, including patient condition, circuit design, and institutional preferences. Centrifugal pumps are preferred in cases where high flow rates are required, such as in severe respiratory failure or cardiogenic shock. Roller pumps, on the other hand, may be suitable for more stable patients or when precise flow control is not critical.
Rotaflow Centrifugal Pump
The Rotaflow centrifugal pump is a commonly used device in ECMO circuits, known for its reliability and performance. This pump utilizes centrifugal force to propel blood through the circuit, providing consistent and efficient blood flow. The Rotaflow pump is designed to minimize shear stress on blood cells, reducing the risk of hemolysis and improving overall circuit performance.
ECMO Flow Chart
An ECMO flow chart outlines the step-by-step process of managing patients on ECMO support. This chart includes parameters such as blood flow rates, sweep gas flow rates, oxygenator performance, and patient vital signs. The centrifugal ECMO pump is a critical component in maintaining optimal flow rates and ensuring adequate oxygenation throughout the ECMO therapy.
