Hot Melt Gear Metering Pumps are the heart of every HotMelt adhesive dispensing system, where metering accuracy is of importance.
Gear metering pumps move entire industries
The chemical dosing pumps are used mainly for high precision metering of fluids. Accurate metering at high pressure is achieved even under the most difficult operating conditions including low viscosity liquids. The metering pump series for chemical applications is available with volumetric outputs ranging from 0.05 to 200 cc/rev. This series is characterized by short flow channels, alternative materials of construction, optional surface treatment and shaft sealing options as well as by a plate packet which is sealed with O-rings.
The trendsetting pump supplier will furthermore showcase the new E-type series of metering pumps which excels in an enlarged setting range at a ratio of 1:40. Thereby each pump covers a considerably wider production window which in turn leads to a greater flexibility in production. Moreover, thanks to the extended production window, a production plant requires fewer pump sizes. Finally, the compact design reduces the space required in a machine. Easy and accurate assembly is ensured by the use of centering dowels.
The dosing of liquids can be challenging in almost every sector. Depending on the complexity, different solutions are conceivable. The suitable dosing equipment can be selected using, among others, the following criteria:
- required accuracy of dosing
- material characteristics
low viscosity | medium viscosity | high viscosity | filled | abrasive
- dosing quantity and dosing time
- temperature
- pressure
Because the processing accuracy of the gear metering pump is very high, whether it is the tooth surface accuracy of the gear, or the gear and the housing, the precision of the cooperation between the gear and the tooth tip is very high, so the displacement of the gear metering pump is certain, In other words, every time the gear rotates, the volume of liquid discharged is constant. Therefore, as the speed of the gear metering pump is adjusted, the gear metering pump can discharge a corresponding amount of liquid. They offer excellent process reliability, even when exposed to the most extreme pressure and temperature conditions.
By measuring the speed of the gear metering pump, the flow rate of the gear metering pump is obtained.
Our Gear Metering Pumps convince by highest precision, high resistance to pressure and temperature as well as excellent wear and corrosion resistance.
