LPG Pump

Wenzhou Supertech supplies liquefied petroleum gas multistage pump the LPGP-65. This centrifugal multistage pump features horizontal construction with 6 stages, mechanical seal without cooling, and a pre-compression turbine at the suction end for low NPSH applications. It delivers high flow rate and high pressure, making it a reliable solution for LPG transfer needs.

Wenzhou Supertech Machine Co., Ltd.supplies LPG pump for LPG tank – the LPGP-150 pump. This pump is engineered for high differential pressure in above-ground and underground tanks, delivering high-flow supply for dual-gun dispensers. As a cost-effective alternative to submersible pumps, this LPG pump for LPG tank features heavy-duty design, simple operation, and economical maintenance for diverse refueling needs.

Wenzhou Supertech Machine Co.,Ltd., a professional manufacturer and reliable supplier of LPG handling equipment, presents its LPG pump for cylinder – an ideal solution for volatile liquid transfer and cylinder filling. Engineered with ductile iron components, floating impeller design, and tool-free maintenance access, this regenerative turbine pump addresses the unique challenges of pumping LP-Gas, ammonia, and similar low-lubricity fluids. With rotatable nozzles, integrated bypass and gauge connections, and a non-contacting impeller that minimizes wear, the LPG pump for cylinder delivers long-term durability, operational simplicity, and consistent performance in demanding industrial applications.

2 Inch LPG Pump is an industrial-grade vane pump specially designed for liquefied petroleum gas (LPG) transfer scenarios. It is widely applicable to high-demand working environments such as unloading gas from tank trucks and filling LPG cylinders. Its core advantage lies in the revolutionary CAM design and heavy-duty bearing structure, which can effectively eliminate cavitation and significantly extend the service life of the pump body under high pressure difference and high speed conditions. In terms of core performance parameters, this pump head supports a rated speed of 680 RPM, a flow output of 18m³/h (approximately 300L/min), a maximum working pressure of up to 28.6Bar, and is equipped with an internal relief valve with a pressure difference of 12Bar to ensure system safety. In terms of technical details, the pump head adopts a single mechanical seal structure and a large-sized non-metallic push rod, which not only simplifies the maintenance and replacement process but also meets the heat dissipation requirements for high-speed rotation. In addition, its cast iron material structure, combined with the NPT 2" inlet and outlet design, enables it to maintain reliable sealing and corrosion resistance within a wide temperature range of -32°C to 107° C. It is an important basic component for achieving domestic substitution and standardization in the LPG refueling equipment industry chain.

Wenzhou Supertech Machine Co., Ltd. offers the 2 inch LPG pump with motor, a rugged vane pump for liquefied gas and ammonia transfer in high differential pressure, high-speed, low suction conditions. Revolutionary cam design eliminates cavitation, while advanced materials and heavy-duty bearings extend service life. Single mechanical seal simplifies maintenance, and large non-metallic push rods enable high-speed rotation. The pump features precision housing, synchronized rotor-blade assembly, roller bearings, and multi-sealing system. Proper tensioning and 80-mesh inlet filtration are required. Priming before startup and avoiding closed-discharge operation ensure reliability.

The SPNP80 oil and gas recovery vacuum pump is a high-performance device designed, manufactured, and tested in accordance with national explosion-proof standards (GB/T3836.1-2021, GB/T3836.2-2021), enterprise standard Q-SPJ 03-2022 "Vapor Recovery Vacuum Pump", and relevant industry standards. All performance indicators of the SPNP80 have reached the domestic advanced level. The oil and gas recovery vacuum pump is suitable for use in Zone 1 and Zone 2 hazardous environments containing explosive gas mixtures of Group IIA, temperature classes T1 to T3. When paired with its dedicated control board, the oil and gas recovery vacuum pump enables precise speed adjustment and air-to-liquid ratio control, making it a core power component for gas station vapor recovery systems.
