𝗠��𝗰𝗿𝗼 𝗣𝘂𝗺𝗽 𝗮𝗻𝗱 𝗙𝗹𝘂𝗶𝗱𝗶𝗰 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 𝗳𝗼𝗿 𝗠𝗲𝗱𝗶𝗰𝗮𝗹 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝘆 - 𝗛𝗲𝗺𝗼𝗱𝗶𝗮𝗹𝘆𝘀𝗶𝘀 𝗣𝘂𝗺𝗽

Overview

Hemodialysis serves as a vital renal replacement therapy for individuals battling chronic renal failure. Over the years, the prevalence of chronic renal failure has risen steadily, particularly due to factors like diabetic nephropathy, hypertensive nephropathy, and renal artery stenosis. This surge in patients necessitates hemodialysis treatment to sustain life.

Dialysis is a life-sustaining treatment for patients with end-stage kidney failure whose kidneys can no longer function. The dialysis machines removing water, solutes, and toxins from the blood. Dialysis works on the principles of diffusion across a semipermeable membrane. Blood flows by one side of a semipermeable membrane and a dialysate on the opposite side. The two main types of dialysis are hemodialysis and peritoneal dialysis.

In peritoneal dialysis, wastes and water are removed from the blood inside the body using the peritoneum as a natural semipermeable membrane.

However, in hemodialysis, the patient’s blood is pumped through a dialyzer. Blood flows through fibers, while dialysis solution flows around the outside of the fibers. The patient’s blood is cleaned in a dialyzer machine from waste products such as urea, creatinine, potassium, and extra fluid pass through the membrane, while the blood cells, protein, etc. remain in the blood.

Choosing the Right Dialysis Pumps

In hemodialysis machines, two circuits are crucial: the blood circuit for extracorporeal circulation lines and the hydraulic circuit for managing dialysis fluid. The hydraulic circuit involves various pumps, TOPSFLO offers a range of pumps engineered to meet OEM specifications for dialysis devices (Model recommendations are as follows):

1. Centrifugal Pumps

2. Diaphragm Gas Pump

3. Magnetic Drive Gear Pumps

External gear pumps are widely acclaimed for their pivotal role in powering dialysis machines, particularly in the medical sector. These pumps operate through the synchronization of two identical gears, commonly referred to as the "motor" and "driven" gears. The motor gear, propelled by a motor, in turn, drives the other gear, facilitating fluid transport by trapping small volumes between the gear teeth and the outer housing wall. This mechanism efficiently moves fluid from the inlet side to the outlet side, making external gear pumps a preferred choice for applications requiring precise fluid pressurization and minimal pressure fluctuations.

The distinctive advantages of external gear pumps contribute to their suitability for health technology applications, notably in hemodialysis machines. These advantages include exceptional priming capacity, ensuring swift initiation of fluid movement. Moreover, these pumps exhibit compatibility with wide temperature variations, a critical feature considering the temperature fluctuations experienced during post-treatment washing. Additionally, the compact size of external gear pumps further enhances their appeal for medical applications, offering an efficient and space-saving solution for fluid management in hemodialysis machines.

Pumps can operate at a temperature of 38°C throughout the dialysis cycle to prevent thermal shock to the patient. Their quiet operation is crucial for patient comfort. Stable performance, vacuum maintenance, and differential pressure are critical factors for the machine's operation, especially biocompatibility. The disinfectants in dialysis equipment pack strength, yet their corrosiveness poses challenges. Enter TOPSFLO pumps, crafted from materials demonstrated to endure numerous chemical heat clean cycles, ensuring unwavering performance. The outcome? A durable pump boasting biocompatibility, minimal noise, and significant reductions in long-term maintenance costs. Choose us for a pump solution where materials make the difference, offering reliability and longevity.

How to Read the Performance Curve of Miniature Diaphragm Pumps (Liquid & Gas)

Understanding the performance curve is crucial for deeper understanding of Miniature Diaphragm Pumps. The performance curve is a key tool that contains a series of key information to evaluate whether the pump can provide the required flow rate under specific pressure differential conditions, helping engineers and operators understand the performance of micro diaphragm pumps under different operating conditions.

What is a Performance Curve?

The performance curves graphically demonstrate the performance of miniature diaphragm pumps at different operating points.

The horizontal axis of the curve represents the pressure, which is usually measured in KPa, bar or MPa, while the vertical axis represents the flow rate, which is usually measured in L/min.

Micro Air pumps are divided into pressure pumps and vacuum pumps. Depending on the application, the performance curve may have a vertical split line that separates the curve into pressure applications and vacuum applications.The left side of the vertical line marks the vacuum application, and the pressure values on the horizontal axis represent the vacuum level at the inlet side of the pump in this application scenario, with the outlet pressure of the pump always maintained at a constant level of 1000 mbar (ambient pressure). The right side of the vertical line marks the pressure application, and the values on the horizontal axis represent the pressure at the outlet side of the pump, which indicates the relative pressure with the ambient pressure is maintained at 1000 mbar.

On the horizontal axis, the two furthest data points represent the two extremes that the pump can achieve, i.e. the ultimate vacuum (on the left) and the maximum pressure (on the right). On the vertical axis, the highest data point represents the maximum flow rate that the pump can achieve.

In addition to the flow rates, the performance curve of some models also indicates that it should be avoided to exceed certain pressure ranges during continuous operation. Although from a technical perspective, the TF30-A12-C01-W104 can achieve a head of over 20M, this range is not included in its performance curve because it exceeds its allowable working pressure range. It is allowed to have pressure exceeding the standard for a short period of time to impact the pump, but if it works for a long time beyond the standard pressure range, the service life of the pump will be greatly shortened.

How to Read the Performance Curve of Diaphragm Pumps

To use the pump performance curve:

Firstly, you need to clarify whether your application falls into the vacuum or pressure category, and identify the flow rate that meets the application requirements as well as the pressure differential between the pump inlet and outlet.

Then, find the point on the performance curve that corresponds to these values to ensure that the pump can operate efficiently.

During the pump selection process, you may also need to consider the power consumption of the pump at that point of operation and other factors that depend on the specific application.

Key Points of the Performance Curve

Limit Points: The two furthest points on the performance graph indicate the lowest vacuum (left) and the highest pressure (right) that miniature diaphragm pumps is capable of achieving. These points may not be shown in every graph as they depend on the type of pump and the permissible operating range.

Maximum Points: The highest intersection point of the curve represents the no-load flow rate of the pump, indicating that there is no restriction or pressure difference between the inlet and outlet of miniature diaphragm pumps. This is the maximum flow rate of the pump.

Application Matching: By identifying whether a specific application is vacuum or pressure and finding the point that corresponds to the required flow rate and differential pressure, ensure that the pump can operate effectively at that operating point.

The Importance of Performance Curves

The performance curve is a key tool in the selection and operation of micro diaphragm pumps, helping to optimize the efficiency and performance of the system. Different models of pumps have different performance curves due to their internal operating principles, so a proper understanding of these curves is critical to the effective selection and operation of diaphragm pump. You can avoid overloading or running the pump in inappropriate ranges, extending its life and saving costs.

Interpreting micro diaphragm pump performance curves can be challenging, but is critical to the proper selection and operation of your pump. As experts in diaphragm pumps, we understand the complexities of performance curves and are ready to provide you with professional assistance to ensure that the pump you select best meets your needs.

Whether you are looking for a diaphragm pump for a specific application or would like to gain a deeper understanding of what performance curves mean, we are always ready to provide you with professional advice and support.
