German APM pump APM model APM price

APM pumps consist of three parts: the drive, the pump head, and the hose. The fluid is isolated within the pump tube; features such as quick tube replacement, reversible fluid flow, dry-running capability, and low maintenance costs constitute the main competitive advantages of peristaltic pumps.

APM pump operating principle

A peristaltic pump works like squeezing a fluid-filled hose with your fingers; as the fingers slide forward, the fluid inside moves forward. The peristaltic pump operates on the same principle, but uses rollers instead of fingers. It pumps fluid by alternately compressing and releasing the elastic delivery hose of the pump. Just like squeezing a hose with two fingers, as the fingers move, negative pressure forms inside the tube, causing the liquid to flow. In a peristaltic pump, a "pillow"-shaped volume of fluid is formed in the section of pump tube between two rotating rollers. The volume of the "pillow" depends on the inner diameter of the pump tube and the geometric characteristics of the rotor. The flow rate is the product of three parameters: the speed of the pump head, the size of the "pillow," and the number of "pillows" generated per revolution of the rotor. The "pillow" size is generally constant (except when pumping highly viscous fluids). When comparing pumps with the same rotor diameter, a pump that generates a larger "pillow" volume will deliver a larger fluid volume per rotor revolution, but will also produce greater pulsation. This is similar to the case of diaphragm valves. Conversely, a pump that generates a smaller "pillow" volume delivers a smaller fluid volume per rotor revolution; moreover, the small "pillows" formed rapidly and continuously result in smoother fluid flow. This is similar to the operating mode of gear pumps.

APM pump advantages

1) No contamination: The fluid only contacts the pump tube, not the pump body; 2) High precision: High repeatability and stability precision; 3) Low shear force: An ideal tool for transporting shear-sensitive and highly erosive fluids; 4) Good sealing: Excellent self-priming capability, can run dry, and prevents backflow; 5) Simple maintenance: No valves or seals; 6) Bidirectional equal flow transport capability; running dry without liquid causes no damage to any pump components; can generate a vacuum level up to 98%; absence of valves, mechanical seals, and packing seals eliminates these sources of leakage and maintenance factors; can easily transport solid, liquid, or gas-liquid mixed phase fluids, allowing solids with diameters up to 40% of the inner diameter of the tubular element; can transport various materials with abrasive, corrosive, or oxygen-sensitive properties, as well as various food products; only the hose requires replacement, and the replacement operation is extremely simple; except for the hose, the transported product does not come into contact with any other components.

APM pump application fields

Chemical industry; mining and metallurgy industry; paper industry; paint and coating industry; food industry; ceramics industry; petroleum industry; water treatment industry; pharmaceutical industry; medical device industry. Pharmaceutical industry applications: The use of peristaltic pumps in the pharmaceutical industry is mainly for drug coating granulation and pharmaceutical dispensing. Spray drying granulators, also known as drying granulators and fluidized bed granulators, are machines used to spray special sugar coatings onto the surface of various instant granular materials, forming granules after drying. These granulators have their own drying heat source, which can evaporate moisture. However, since moisture evaporation and granule formation are dynamically related, the amount of sprayed liquid and water must be very precise to ensure a certain humidity level for the granules, thereby facilitating perfect granule formation.
