CDF type water ring vacuum pumpDetailed product description：

Product Introduction
The CDF series water ring vacuum pump is a reliable, stable, and easy to maintain energy-saving new product developed using modern hydraulic model design technology. Through technological improvements, the second-generation product of CDF vacuum pump, CDF (II) series, has been launched in recent years.

CDF (II) Model Description

CDF 140 2(T) - 0 A D 2
|| | | | | | __ Type code for shaft seal. '2' is a single end face internal water supply machine seal
|| | | | | ____ transmission mode. D: Direct drive
|| | | | _______ Structural material code. The impeller material of "A" is stainless steel or copper, and the other overcurrent parts are made of cast iron (conventional configuration)
|The impeller material of "B" is stainless steel or copper, the distribution plate material is stainless steel or copper, and the other overcurrent parts are cast iron
|The material of the "N" overcurrent components is all 304 stainless steel
|The material of the "H" overcurrent components is 316 stainless steel, etc
|| | | _________ Inhalation limit pressure code. '0' can reach 33mba (absolute pressure). Recommended for use at ≥ 80mbar (absolute pressure)
|| | ________________ Second generation improved model. The structure with "T" is a bracket structure, while the structure without "T" is a direct connection structure
|| ________________ Impeller size code
|_______________________Pump series code

Note: The direct connection structure CDF1202-2212 only has two material configurations, A and B.

Application Domain
Vacuum drying and packaging in industries such as pharmaceuticals and food processing, vacuum extrusion and forming of plastics in the rubber industry, liquid degassing in the water supply plant water pump vacuum water diversion chemical industry, vacuum filtration, distillation, and wet stains in the textile industry

Product Features
1. Reliable quality, certified by ISO9001 quality system.
2. The CDF (II) series water ring vacuum pump is used to suction gases that do not contain solid particles or allow for non granular dust, insoluble or slightly soluble in working fluids.
3. The structure is simple, compact, space saving, easy to install, and easy to maintain.
4. The exhaust port equipped with a flexible valve plate can automatically adjust the exhaust angle, allowing the pump to operate efficiently throughout the entire vacuum range.
5. The maximum vacuum can reach an absolute pressure of 33mbar, and with an atmospheric injector, a higher suction vacuum can be obtained.
6. The shaft seal adopts mechanical seal type as the standard configuration, which is reliable and reduces equipment maintenance.
7. Smooth and reliable operation, low noise, no need to configure silencing configuration.
8. Oil free design, low water consumption, conducive to environmental protection.
9. The materials of overcurrent components are diverse and can adapt to the requirements of different working conditions.
10. If requested by the customer, a complete set of CDF (II) units can be provided, which may include gas water separators, heat exchangers, cavitation protection connecting pipes, etc.

The specific model and performance parameters of CDF (II) series water ring vacuum pump are as follows:
