The VF-1.4 (5-7) -250 CNG Compressor, manufactured by Bengbu United Compressor, is a high-performance solution designed for efficient natural gas compression and transportation. As a key product in the CNG compressor lineup, it excels in boosting and conveying natural gas in pipeline networks, while also adapting to diverse industrial needs.
With a processing capacity of 500Nm³/h, this compressor operates at an inlet pressure of 0.5-0.7MPa.G and delivers an exhaust pressure of 25MPa.G, powered by a 110kW main motor. Its compact design—measuring approximately 5500 × 2200 × 2000 mm and weighing around 7T—ensures flexibility in installation across various environments.
Beyond pipeline applications, the VF-1.4 (5-7) -250 CNG Compressor supports extended uses such as stirring in pharmaceutical and brewing industries, pressurized gas transport in chemical sectors, bottle blow molding in food production, and part dust removal in machinery manufacturing. Its modular design and advanced engineering make it a reliable choice for both standard and custom requirements.
Engineered for efficiency, the VF-1.4 (5-7) -250 CNG Compressor boasts high operational efficiency, strong reliability, and a high degree of automation—critical for continuous industrial operations. Its D-type (symmetrical balance) structure, water-cooled system, oil-free lubrication, and reciprocating piston design (2 rows, 3-stage compression) ensure stable performance even under demanding conditions.
The compressor’s components are precision-engineered, with key parts like the crankcase (gray cast iron) and cylinder (gray cast iron/forged steel) built to withstand heavy usage. This attention to detail minimizes downtime and maximizes productivity.
Designed with usability in mind, the VF-1.4 (5-7) -250 CNG Compressor features fewer vulnerable parts, reducing the need for frequent repairs. Its low vibration and noise levels create a safer, more comfortable working environment.
Maintenance is simplified by intuitive access to critical components: the crankcase includes ports for oil level observation, oil injection, and temperature measurement, while a manual ball valve facilitates easy oil drainage. The double-middle-body structure prevents oil from contaminating the gas medium, ensuring clean operation and reducing maintenance costs over time.
The compressor’s main and auxiliary equipment are integrated onto a skid, enabling smooth transportation and hassle-free installation. This sledge - mounted design is ideal for both fixed and mobile applications, adapting to on-site conditions with ease.
For unique requirements, customization options are available, including:
· Structural forms (D-type, M-type, S-type, W-type, V-type, Z-type)
· Cooling methods (water-cooled, air-cooled, mixed cooling)
· Installation types (fixed, mobile, skid-mounted, cabin-type)
· Drive modes (motor-driven, diesel engine-driven)
Backed by advanced technology, the VF-1.4 (5-7) -250 CNG Compressor holds multiple patents, including:
· Piston rod thread protective sleeve (ZL 2017 2 1907021.7)
· Piston ring support device (ZL 2018 2 0294776.2)
· Range piston for symmetrical balanced compressors (ZL 2017 2 190177.0)
· Integrated long-short double compartment (ZL 2018 2 0294762.0)

Whole Machine Description
The compressor adopts D-type (symmetrical balance type), water-cooled, oil-free lubrication, reciprocating piston type, 2-row 3-stage compression, and the entire unit is supplied in a modular manner.
The compressor crankcase is made of gray cast iron and has four holes of different diameters for installing crosshead slides, bearings, and bearing seats. The lower part of the crankcase can store lubricating oil for the compressor to lubricate; The upper surface of the crankcase has an interface for installing a fuel inlet (breathing port) cover plate; In addition, the crankcase also has spare interfaces such as oil drain port, oil gauge observation port, bearing seat oil injection port, and installation oil temperature measurement port. The oil drain port of the crankcase has been connected to the outside of the compartment and is equipped with a manual ball valve for oil discharge from the crankcase.
The middle body of the compressor is a double middle body structure, ensuring that the middle body space is greater than one stroke, preventing compressor oil from entering the cylinder from the crankcase, thus ensuring that compressor oil does not contaminate the medium. The material of the compressor cylinder is gray cast iron/forged steel, and it adopts an oil-free lubrication design, which does not require oil lubrication. The cylinder head material is gray cast iron/forged steel, and the air valves are arranged axially on the cylinder head.
