• Versatility: These pumps can handle multiple fuels like propane, LPG, butane, and anhydrous ammonia, making them suitable for a variety of industrial applications.

• Durable Construction: Built from ductile iron, the pumps are designed for long-lasting performance under demanding conditions. They are equipped with Blackmer’s mechanical seal and ball-bearing construction, ensuring reliability and minimal maintenance.

• Cavitation Suppression: A unique feature of these pumps is their cavitation suppression liners, which effectively reduce noise, vibration, and wear caused by entrained vapors, enhancing operational efficiency.

• Easy Maintenance: The internal pumping chamber can be easily restored to like-new condition through the replacement of the casing liner and end discs. This makes maintenance straightforward and cost-effective.

• Internal Relief Valve: Each pump comes with an internal relief valve that protects the system from excessive pressures, ensuring safety and preventing damage.

• Mounting Flexibility: The pumps can be mounted on bobtails, transports, or steel pads welded to tanks. The 3- and 4-inch models can be installed between tank landing gear brackets for added convenience.

• Integrated Unit Assemblies: For ease of installation, Blackmer offers pre-configured assemblies that come with the motor, gearbox, baseplate, coupling safety covers, and the LGL Sliding Vane Pump. These assemblies are ready to install with no need for alignment, offering a streamlined solution for users.

• Symmetrical Bearing Support: This design ensures even load distribution and minimal wear, extending the lifespan of the pump.

• Certified for LPG and NH3: The pumps are certified by Underwriters Laboratory for use with LPG and anhydrous ammonia, adding a layer of safety and reliability.

• Quiet Operation: The cavitation suppression liner and other features allow these pumps to operate quietly, providing an efficient and noise-reduced solution for transport and transfer systems.
