LGL1.5 LP-gas Sliding Vane Pump

The LGL1.5 LP-gas Sliding Vane Pump is a durable positive displacement pump designed specifically for LP gas applications. Manufactured by Blackmer PSG Dover and distributed by KI Pumps of Waukesha, WI, it provides reliable performance for various transfer tasks, including fueling, cylinder filling, and small-scale gas transfer jobs. The pump is made with materials suitable for LP gas handling, featuring Buna-N mechanical seals and Duravanes to ensure safe operation with gases like LP and anhydrous ammonia. Its operational capacity ranges from 9 to 35 gallons per minute (34 to 132 liters per minute), making it suitable for a range of industrial and commercial applications on a budget.

The pump construction includes a replaceable casing liner and end discs, allowing straightforward rebuilding and maintenance. The LGL1.5 features a rotatable pump body to facilitate piping connections, especially when equipped with integral brackets and flange mounts for easy attachment to NEMA C-face motors. Ports are 1.5 inches NPT tapped, and it incorporates an internal relief valve set to a maximum differential pressure of 150 psi (10.34 bar). To reduce noise, vibration, and wear caused by cavitation, the design includes cavitation suppression liners, promoting quieter operation and extending the pump’s service life.

Dimensions specify a 1.5-inch NPT port size compatible with typical LP gas transfer systems. The pump weighs approximately 25 pounds (11.3 kg) and has a compact footprint suitable for limited-space installation environments. It can withstand a maximum differential pressure of 150 psi, supporting a variety of fueling and transfer applications with reliable performance. The design emphasizes ease of rebuilding, requiring no specialized tools, which minimizes downtime and operational costs, making it an efficient choice for professionals on a budget.

Suitable use cases for the LGL1.5 include fueling stations that need efficient gas transfer, cylinder filling operations at small-scale industrial or commercial facilities, and transfer jobs involving LP gas or compatible gases. Its efficiency, capacity, and easy maintenance make it an ideal option for small to medium-scale gas handling tasks, especially when cost-effective solutions are prioritized.

Each LGL1.5 pump ships with the main pump body, integrated relief valve, spare casing liner, and necessary mounting hardware. Excluded are the NEMA C-face motor and piping accessories, which are purchased separately according to specific system requirements.

Maintenance involves regular inspection of seals and liners for signs of wear, cleaning to prevent buildup, and replacement of worn components to ensure optimal performance. The LGL1.5 pump supports straightforward rebuild procedures, encourages long-term use, and includes a manufacturer’s warranty covering parts and craftsmanship.
