Vacuum ring pump 0,75 KW
The single-stage vacuum pumps are versatile, offering a wide range of applications when it comes to transporting liquids due to their simplicity, reliability, and robustness. The device operates with minimal vibrations, and its noise levels do not exceed the prescribed standards. Additionally, it ensures oil-free operation.
The pump features a monoblock construction, directly mounted on the motor flange in compliance with the B3/B5 standard. It is driven by a flexible coupling.
Shaft support is ensured by two ball bearings lubricated for life, while the shaft seal adopts a single-acting mechanical seal according to DIN 24960 (standard material selection C/SiC/Viton). The pump is made primarily out of cast iron, it includes stainless steel components such as the impeller and the connection to the plate.
Application
- Bottle filling
- Evaporation/distillation
- Vacuum processing
Operation
During operation, it is essential to feed the pump with a liquid, typically water. This is crucial to maintain the stable rotating piston effect and facilitate the removal of the heat load generated during the compression of the pumped gas mixture.
The following performance curves showcase the pump's efficiency under various conditions:
Â
The curves' values are based on the use of 15°C water as the service liquid, drawing in ambient air composed of dry and rarefied air at an ambient temperature of 20°C. The atmospheric pressure is set at 1013 mbar. For enhanced vacuum performance, a gas ejector can be installed in front of the pump, utilizing the pressure difference created by the pump.
The ejector's operational range should ideally stay below 40 mbar, with a minimum achievable suction pressure of 10 mbar.
