Caution
1. Oil is deteriorated with operating, and becomes the factor of performance shortage.
A decrease and the dirt of oil are confirmed, and please regularly add and replace it.
2. A backflow preventer is incorporated into the pump to prevent the oil from flowing back while the pump is stopped.
Please make a suction side into atmospheric pressure when the pump is stopped for a long time.
3. If operation is performed at high pressure, oil mist is generated at the exhaust side.
We will recommend the use of the oil mist separator for the oil mist splash prevention.
4. The influence might go out to the pump life according to the characteristic and the amount of the evacuated gas.
Especially, longevity is remarkably shortened, and corrosion resistance might not be able to be demonstrated about ammonia and sulfuric acid.
5. It is not suitable for the pump if operation is performed continuously at a high evacuation pressure of 1kPa or more.
6. There is a risk of explosion. Never block the outlet or operate the pump with equipment mounted at the outlet side that blocks the passage of gas.
Otherwise, the internal pump pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded.
7. Same parts of the pump are made by carbon.
Oil becomes black with wear-out powder of carbon parts, when operation is doing.
But it doesn’t affect the performance and service life of the pump.
8. Fluoride rubber material is used for the internal parts of a pump.
There are some for which the chemical resistance of Fluoride rubber materialis not suitable.
Especially, be careful of the following chemical.
Ammonia, Acetone, Ethylene oxide, Ethylene diamine, Zinc acetate, Amyl acetate, Aluminum acetate, Isopropyl acetate, Ethyl acetate, Lead acetate, Calcium acetate, Cellosolve Acetate, Nickel acetate, Butyl acetate, Propyl acetate, Methyl acetate, Nitroethane, Nitropropane, Nitromethane, Freon.
