Product Details
Welch CRVpro8Chem
Oil self-cleaning pump
——Equipped with integrated oil filter
Welch CRVpro8ChemEspecially suitable for freeze-drying or vacuum concentration processes containing irritating chemicals, such asTFAAcetonitrileHBrWait. These chemicals can quickly corrode the pump oil of unprotected vacuum pumps.CRVpro8ChemThe design can better resist the impact of these corrosive chemicals on the pump.
The oil filter uses alumina elements that can neutralize acids and remove solid reaction products from the oil. The capacity of the oil filter is1.3Sheng can dilute the pollutants generated during the use of the pump and mixed with the pump oil.
The inner wall of the fuel tank of the oil pump hasPTFECoating, the outer surface of the pump core has a black oxide coating, which enhances the chemical corrosion resistance of the oil pump.
CRVpro8ChemuseWelch Gold oil (serial number8995G-11),This is a double distillation synthetic hydrocarbon oil. Synthetic hydrocarbon oil does not contain aromatic compounds or sulfur, which can reduce adhesion, slagging, and carbon deposition, and has good chemical corrosion resistance.
CRVpro8ChemEquipped with an oil filter, internal metal surface protective coating, and synthetic hydrocarbon oil, this triple protection greatly reduces the corrosion rate of metals and pump oil. Compared to oil pumps that are not protected by the above measures,CRVpro8ChemThe maintenance interval and service life have been significantly extended.
√ Better resistance to chemical corrosion
Equipped with an oil filter, it can continuously neutralize acids and remove solid reaction products from the oil
√ Internal metal surface protective coating
√ Use synthetic hydrocarbon oil

Instructions for Use:
Freeze drying:
Vacuum pump oil may be quickly damaged by steam from freeze-drying equipment. Once the pump oil is chemically damaged, its lubrication performance will decrease, and the vacuum pump will soon need to be repaired.
1. Organic solvents, acids, and other sublimation vapors may pass too quickly through the freeze dryer collector and cannot be effectively condensed. Generally, better protection of vacuum pumps can be achieved through the following methods:-84Please use a low-temperature trap, which usually needs to be lowered to ℃
2. Or lower;
Please ensure that the freeze dryer operates under vacuum sealed conditions. The excessive flow generated by system leakage will render the cold trap ineffective.Welch
