Water ring vacuum pump manufacturer’s quotation

When purchasing water ring vacuum pump, the quotation of the pump depends on the brand, type, model, material, process, motor and other factors of the pump, to provide enough parameters, technical exchanges after the quotation.

1. Brand. The price of different brands is different. Domestic brands are cheaper than imported brands, and convenient after sales. Domestic vacuum pump brand, which brand is good, which brand of the price does not exceed the enterprise this purchase amount.

2. Type. According to the requirements of working conditions, the type of pump should be selected, which is more suitable for the screw pump or the water-ring vacuum pump. Comparatively speaking, the screw pump is higher than the water ring pump price. Some need to choose the combination of vacuum pump (namely: vacuum unit), in order to make the vacuum system to get a better vacuum degree and exhaust volume, also decided to purchase the price will increase.

3. Model: select the model required by the enterprise according to the process and many parameters of the exhaust volume. For example: water ring vacuum pump different models, sizes and prices are different.

4. Material selection, suitable for enterprise process, whether the exhaust is corrosive. (depending on the parameters) can be customized, different positions with different materials. Antiseptic material can choose stainless steel and titanium material. Titanium itself is known to cost more than stainless steel. It is stainless steel 304 and 316L likewise, although physical property is about the same, mechanical property is close, tensile strength, yield strength, elongation, sectional shrinkage rate all is same, physical property is same. However, there is a clear difference in corrosion performance, 316L is better. As a result, there must be a difference in price.

5. Motor, ordinary motor, brand motor, frequency conversion motor, explosion-proof motor. The better the motor, the higher the requirements for the motor, the cost is different.

6. Accessories, different vacuum pump factory accessories are different. The difference in price between imported parts and domestic parts can be determined to be different. For example: a vacuum pump manufacturers used 3 imported parts, b used 7 imported parts. When quoting, both sides will certainly add the cost. Imported parts in precision and quality than domestic parts will be better. If the quality difference is not big, the enterprise will use domestic parts instead of imported parts. (try to reduce production cost on the premise of ensuring product quality)

7. With different technologies, production equipment and technical levels, the level of technicians and technical engineers is also proportional to the production cost and product quality under various factors. As the saying goes, “to do a good job, you must first sharpen its tools,” “no diamond not porcelain live.
