LGL1.25 LP gas Sliding Vane Pump

Product Identity

The LGL1.25 LP gas sliding vane pump is a durable and reliable positive displacement pump designed for fueling and transfer applications involving liquefied petroleum gas (LPG). Manufactured by Blackmer PSG Dover and distributed by KI Pumps, this model offers efficient performance in industrial settings requiring consistent fluid handling.

Materials and Construction

The pump features a casing liner and end discs constructed from replaceable materials for ease of maintenance and rebuilding. Standard seals are Buna-N mechanical seals, providing chemical resistance suitable for LPG and anhydrous ammonia. The casing incorporates cavitation suppression liners to reduce noise, vibration, and wear, extending operational lifespan. The pump is built for durability with high-quality internal components capable of withstanding maximum differential pressures of 150 psi (10.34 Bar).

Dimensions and Specifications

The LGL1.25 model includes 1.25-inch NPT tapped ports for fluid inlet and outlet connections. It is designed for foot mounting on a common base-plate or direct flange mounting via an integral bracket with coupling for NEMA C-face motors. Pump weight varies based on configuration but is optimized for compact installation within small-to-medium transfer systems.

Features

• Capacities range from 9 to 35 U.S. gallons per minute (34-132 L/min), suitable for various transfer tasks
• Equipped with an internal relief valve to regulate pressure
• Replaceable casing liner and end discs for simplified maintenance and rebuilding
• Built-in cavitation suppression liners to minimize noise, vibration, and wear during operation
• Designed for LP gas and anhydrous ammonia handling with Buna-N mechanical seals and Duravanes materials
