The rotary piston pump has the industry's most efficient and space-saving design , sets the standard for performance and reliability . After improvements, upgrading and fine-tuning , higher reliability of the pump plunger and production efficiency , and maintenance and process downtime reduced to a minimum . Integrated oil distribution system eliminates the use of external piping , unique design, can run without leakage . Motor mounting platform higher rigidity , thereby reducing the flexibility and minimize the wear of the motor belt . Reservoir cover and the side cover O -ring design of novel , improved sealing to prevent oil leakage. Built- in side airbag cover in an integrated valve can be quickly adjusted for auto airbags. Most importantly , these improvements will not increase the footprint, space saving is still the industry leader. This pump is equipped with an oil control solenoid valve 230/460V coil is used , the oil solenoid valve to prevent malfunction or loss of vacuum pump oil to overflow inside the power supply.

Features and Benefits :
• rugged ductile iron construction provides a proven and reliable operation.
• Run at low speed 500rpm when the maximum pump life .
• Efficient design with few moving parts , low speed and large gaps so greatly extended running time .
• You can reach as low as the low ultimate vacuum of 2.5 x 10-2 Torr .
• using the new bonnet design , maintenance-free and noiseless operation .
• Space-saving design can save up to 50% of valuable floor space.
• deliver a complete and independent unit , ready for installation.
• Automatic lubrication system can be transported to the correct bearings and oil seals the surface and prevent it back into the system.
• Controlled balance will be reduced to a practical minimum vibration .
• airbags as standard components available.
• The overall features include a variety of production and maintenance functions , so that the device can maintain optimal running through extensive vacuum system accessories .
