I. Range of Usage
BE-series single and two stage oil-circulation spiral slice vacuum pumps are
basic equipment to vacuate air-tighted vessel. They are applicable to refrige-
rating service (for R12, R22, R407C and R134a refrigerant), printing machi-
nery, medical machinery, vacuum packaging, gas analysis, thermoplastic
molding and other industries. They can also serve as primary pump for
various fine vacuum equipment.
Two-stage oil-circulation spiral slice vacuum pump is to vacuate on the basis
of single stage pump and it can realize most vacuums.
II. Features
Anti-oil-returning design
Special air passage is designed to prevent pump oil from returning to conta-
minate vacuum vessel and pipeline after the pump stops.
Environment protection design
The product has a built-in device to eliminate oil mist and an oil-gas separator
at air exhaust outlet to treat with oil contamination in air exhaust.
Aluminum alloy motor casing
Motor adopts aluminum alloy to make its casing, which has high rate of heat
emission and can guarantee continuous normal operation. Its appearance is
also good looking.
Integrating design
The motor and pump are integrated to make product compact, simple and ra-
tional.
Large starting torque
This product is specially designed for low temperature and low voltage condi-
tion to guarantee a normal starting in winter (≥5°C temperature) and rated
voltage ±10%.
Oil circulation design
The product runs with extremely high ultimate vacuum and low noise.
