LGBN Series Single Screw Pump

LGBN progressive cavity pumps are available with various rotor/stator geometries and can be mounted either horizontally or vertically, and the suction casing can be rotated. They operate with minimal pulsation, and a uniform and controlled flow without the need for pulsation dampeners or compensators. The N pumps feature high self-priming capabilities even with a mixture of liquid and air/gas up to a 9 m (29,5 ft.) water column. They are equipped with round flanged suction and pressure connections and also feature large spherical inlet openings for the easy intake of media that contain solids. Depending on your need, our pumps deliver up to 48 bar, while our pump equipped with a free bare shaft delivers up to 96 bar in pressure. Their conveying capacity varies from 0.01 to 500 m³/h. Each pump provides a specific design: short and compact, large and easy to maintain, bare free shaft and an API 676 standard pump for oil and gas applications.

Features and advantages：
Low pulsation
The low pulsation promotes steady and smooth transfer of media without the need for additional dampeners or compensators.
Gentle transport
Ideal for pumping sensitive media, the low speed capabilities allow for low shearing of media.
Flexible installation options
Product Group N pumps can be installed in a horizontal or vertical position, including a large, rotable and spherical suction intake.
Compatibility
LGBN pumps are available with a wide range of rotor/stator geometries and a selection of various shaft seals. This makes the pumps able to suit any conveying process
Powerful suction.
The design allows for powerful suction to facilitate transport of viscous media, gas-liquid mixtures with a water column of up to 9m (29.5 ft.)

Features and advantages:
Save space
Since the drive is mounted directly behind the direct-connected bracket, no additional bearing boxes are required.
Easy maintenance
Easy maintenance due to the quick-release plug-in connection between the device and the drive system
Low pulsation
Smooth and uniform pumping flow without dampers or condensers - especially for sensitive pumping media
Flexible installation
The suction chamber can be rotated flexibly according to the field working conditions
Good compatibility
A variety of rotor geometry and different shaft seals are available, tailored to suit a variety of conveying processes
Cost saving
No additional bearing boxes, couplings and common bottom plates are required, reducing material costs
