The 2BV series water ring vacuum pump is designed for pumping air mixed with water vapor. It can achieve an intake pressure as low as 33 mbar (absolute), equivalent to a vacuum level of 97%. When operating under conditions close to the limit vacuum (i.e., the saturation vapor pressure of the working fluid) for extended periods, it is recommended to connect a cavitation protection tube to safeguard the pump. When used as a compressor, the maximum pressure can reach up to 0.26 MPa (absolute).
As a next-generation energy-efficient product, the 2BV series offers superior performance and a range of advantages, making it a complete replacement for older models such as the SK, 2SK series water ring pumps, and the W, WY, WL reciprocating pumps.
Main Features
1. Direct coupling design saves space and simplifies installation and maintenance.
2. All units are equipped with a cavitation protection tube. If operating at or near the maximum vacuum, opening the cavitation protection tube (or connecting it to a separator) ensures optimal suction performance during cavitation and protects the pump.
3. The 2BV series can be fitted with a stainless steel impeller, offering high strength, durability, and enhanced corrosion resistance.
4. A unique flexible air outlet design prevents over-compression, ensuring maximum efficiency and performance.
5. All models use Y2 series motors with IP54/IP55 protection (standard IP44) and Class F insulation (standard Class B).
6. The flexible seal can be fully made of PTFE, significantly increasing the pump’s lifespan under harsh conditions.
This advanced vacuum pump is ideal for industrial applications where reliability, efficiency, and long-term performance are essential. Whether used for vacuum generation or compression, the 2BV series provides a robust and energy-saving solution that meets modern standards. --- Total characters: **574**
As a leading provider of tooling mold
manufacturing and injection moulding solutions, we excel in producing Condiment
Bottle Cap molds. Our precision manufacturing achieves tight tolerances,
guaranteeing each cap fits perfectly.
We use high-quality mold insert steel to
ensure durability and longevity, which is essential when producing large
quantities of condiment bottle caps. We will shorten the cycle time and improve
production efficiency according to the characteristics of bottle cap molds. We
will conduct strict quality control to minimize the defective rate of plastic
injection molding.
For bottle caps mould, they are generally
required to be mass-produced, so injection molding usually uses PP or PE
materials. We are experienced with materials like PP and PE, ensuring optimal
processing and final product quality. Our expertise includes multi-cavity
designs to enhance efficiency and specialized surface finish for improved
durability and aesthetics.
