The peristaltic pump tubing is composed of three parts: the driver, the pump head, and the hose. The fluid is isolated in the pump tube, which can quickly replace the pump tube, the fluid can flow reversely, and it can run dry, making the maintenance cost low. These characteristics form the main competitive advantages of the peristaltic pump tubing.
The peristaltic pump tube tubing is squeezed by two cams installed on the shaft in succession. The first cam squeezes the hose wall, forming a vacuum in the hose to suck the fluid into the tube.
Now the fluid enters the hose, and the second cam will squeeze the hose, pushing the fluid to move toward the discharge end.
When the cam rotates to the discharge end and starts to separate from the hose, the diagonal cam starts to squeeze the hose to ensure that the fluid will not flow back. In this way, the peristaltic pump tubing sucks and pumps the fluid by continuously squeezing two cams.
Using a peristaltic pump tubing is to obtain the required flow rate, so according to the operation and use of the peristaltic pump tubing, a good pump requires a good silicone tube. So what characteristics should a good peristaltic pump tubing have?
Peristaltic pump tubing characteristics: using high-purity imported silicone rubber raw materials, platinum vulcanization vertical extrusion molding, smooth inner cavity, long-time compression of the inner wall without sticking, precise dimensional tolerances, uniform wall thickness without eccentricity, high wear resistance, high tear resistance, and high resilience. It can meet food hygiene, drug pharmacopoeia, medical and other inspection standards.
The chemical stability of the peristaltic pump tubing
The peristaltic pump tubing can withstand weak acids and alkalis, such as weakly corrosive drugs, low-concentration potassium permanganate, acetal reagents, animal oil, vegetable oil, petrolatum, glucose, ethanol, hand soap, juice, disinfectant, blood, weakly acidic and alkaline gases, etc.
The peristaltic pump tubing is not suitable for strong acids, strong alkalis, and organic solvents, such as concentrated sulfuric acid, hydrochloric acid, sodium hydroxide, nitric acid, lubricating oil, silicone oil, mineral oil, engine oil, gasoline, diesel, hydraulic oil, high-concentration acetone, carbon tetrachloride, high-concentration ozone, etc.
Peristaltic pump tubing can work in an environment of -50-200℃, can be repeatedly high-temperature and high-pressure sterilization, can be sterilized by ethylene oxide, Y-ray, and β-ray irradiation.
Wear resistance of the peristaltic pump tubing: The speed and flow rate of the peristaltic pump tubing can be adjusted. The maximum test life of the platinum silicone peristaltic pump tubing tube is: at a speed of 300 rpm and the medium being water, its continuous service life is 500 hours. It is 5-10 times more durable than platinum silicone tubes made from other imported materials.
Wall thickness of the peristaltic pump tubing: The wall thickness of the peristaltic pump tubing tube affects the resilience performance of the hose, and the resilience performance affects the service life of the hose. It is generally recommended to choose a pump with a lower speed on the premise of meeting the flow rate.
