overview
The EM series oil sealed rotary pump is renowned for its high ultimate vacuum and pumping speed, low operating noise, and ability to handle steam, and has become the industry standard for laboratory and light industry applications.
E1M18 and E2M18 pumps are direct coupled slide pumps. The pump is oil sealed and designed for reliable long-term operation. The pump is a freely placed device, and its transmission is provided by a single-phase or three-phase (four pole) motor through a movable coupling.
Comes with the product: Ultragrade 19 oil, NW25 O-ring, and centering ring. It is necessary to purchase Fomblin separately for the PFPE pump ®。
Characteristics and advantages
The pump is designed for reliable long-term operation.
Thermal overload equipment can prevent overheating (only applicable to single-phase models).
The transmission is provided by a single-phase or three-phase (four pole) motor through a movable coupling.
The motor is fully enclosed and cooled by a motor cooling fan.
The pressure die-casting oil tank with integrated oil seal can prevent oil leakage.
The gas damper has a very high ability to transport water vapor.
Tested by external organizations, it complies with EN61010, CSA, C22.2, and UL61010 standards.
The oil observation window sealed with a large O-ring allows for easy observation of the oil condition and level.
