Preeflow
Brand reference:74059
The preeflow automatic dispensing system has more than 25 years of experience in fluid metering. ViscTec stands out with its comprehensive expertise in dispensing technology. In 2008, this extensive experience was expanded with the launch of the preeflow brand. Success: For 15 years, preeflow has represented precise and purely volumetric fluid dispensing for small batches and very small quantities. Industries around the world rely on preeflow products. Always following our philosophy: smaller, more precise, more economical.

German Preeflow valves Preeflow models Preeflow prices
Preeflow valves, also known as flap valves, are simple-structure regulating valves. Butterfly valves, used for on/off control of media in low-pressure pipelines, refer to valves where the closing element (valve disc or butterfly plate) is a disk that rotates around the valve shaft to achieve opening and closing. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metals, and radioactive media. They mainly serve to cut off and throttle flow in pipelines. The opening and closing element of a butterfly valve is a disk-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening and
German Preeflow pump Preeflow model Preeflow price
Preeflow pump is a typical positive displacement hydraulic machine, driven by a prime mover, converting input mechanical energy into pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow. It is the power source of the hydraulic system. Since it can transport liquids under high pressure, it is widely used in various industries in industrial production and daily life, such as water conservancy, construction, and energy. In addition, it is also widely used in shipbuilding, oil extraction, and loaders. Preeflow pump usage method For plunger pump cylinders with installed copper sleeves, it is possible to
German Preeflow coupling Preeflow model Preeflow price
Preeflow couplings are mechanical components used to connect two shafts (driving shaft and driven shaft) in different mechanisms, enabling them to rotate together to transmit torque. In high-speed, heavy-load power transmission systems, some couplings also provide buffering, vibration damping, and improved dynamic performance of the shaft system. A coupling consists of two halves, each connected to the driving shaft and the driven shaft respectively. Generally, prime movers are connected to working machines via couplings. Preeflow coupling structure and features: A diaphragm coupling consists of at least one diaphragm and two hubs. The diaphragm is fastened to the hubs with pins.
German Preeflow bearings Preeflow models Preeflow prices
Preeflow bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. These rollers are called needle rollers. Despite having a small cross-section, the bearings still have high load-carrying capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, where L is the roller length), resulting in a compact radial structure. When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, making them particularly suitable for support structures with limited radial installation space. Depending on the application, bearings without inner rings can be selected.
Preeflow controller, German Preeflow model, Preeflow price
The Preeflow controller uses a chip to control switches at various positions in the LED lamp circuit. There are two types of controllers with different structures due to different design methods. A micro-operation is an operation that cannot be further decomposed; performing a micro-operation always requires a corresponding control signal (called a micro-operation control signal or micro-operation command). A digital computer can basically be divided into two parts: the control unit and the execution unit. The controller is the control unit, while the arithmetic logic unit, memory, and peripheral devices are the execution units relative to the controller. Control unit
