Durability / High Efficiency / Quiet Operation / Easy Maintenance

N/A Blackmer offers a full line of liquefied gas pumps and oil-free gas compressors, designed for maximum performance and reliability. From the smallest cylinder filling operation to the largest, most sophisticated bulk plant/rail car unloading system, you will find Blackmer pumps and compressors operating throughout the world.

Sliding vane design is ideal for butane, propane, anhydrous ammonia, propellants, refrigerants and similar liquefied gases
Blackmer liquefied gas pumps are widely used for cylinder filling, motor fueling, bulk transfer, vaporizers, and on bobtails and transports.
Utilizing Blackmer’s unique sliding vane design, these positive displacement pumps offer the best combined characteristics of sustained high-level performance, energy efficiency, trouble-free operation, and low maintenance cost.
Pump models are available in 1 to 4-inch port sizes. All models have ductile iron construction for thermal shock resistance, low friction ball bearings for high efficiency and quiet operation, and threaded lock collars that prevent end thrust wear.

Cavitation Suppression Liners
1.25 through 4-inch models now have special liners that "cushions" the effects of collapsing vapor bubbles within the pump, sharply reducing the noise, vibration, and wear normally caused by entrained vapors.

How Blackmer Sliding Vane Pumps Achieve High Efficiency

N/A Blackmer pumps use a rotor with sliding vanes that draw the liquid in behind each vane, through the inlet port and into the pumping chamber. As the rotor turns, the liquid is transferred between the vanes to the outlet where it is discharged as the pumping chamber is squeezed down. Each vane provides a positive mechanical push to the liquid before it.

Vane contact with the chamber wall is maintained by three forces: (1) centrifugal force from the rotor’s rotation, (2) push rods moving between opposing pairs of vanes, and (3) liquid pressure entering through the vane grooves and acting on the rear of the vanes. Each revolution of a Blackmer pump displaces a constant volume of fluid. Variance in pressure has minimal effect. Energy-wasting turbulence and slippage are minimized and high volumetric efficiency is maintained.

Efficiency Means Energy Savings

N/A The high efficiency of Blackmer pumps means they require less horsepower than other positive displacement pumps. So you spend less on motors initially and less on electricity to operate the pumps after they are installed.

High Capacity at Lower Speeds Means Reduced Wear

N/A The volumetric efficiency of Blackmer pumps saves more than energy. Their inherently low slippage allows them to operate at substantially lower rpms than other positive displacement pump types, while still delivering equivalent output. These lower operating speeds mean quieter operation, longer service life, and reduced maintenance requirements.

Self-Adjusting Vanes Keep Performance High

N/A The performance of gear pumps will constantly diminish as wear increases clearances. To compensate for the reduced performance, you must increase the pump speed (which further accelerates pump wear) or put up with reduced capacity until performance drops to a totally unacceptable level. The vanes on a Blackmer pump automatically slide out of their rotor slots to continuously adjust for wear. No more speeding up to compensate and no more putting up with poor performance. Blackmer pumps maintain near-original efficiency and capacity throughout the life of the vanes.

Vane Replacement in Minutes, Easy Inspection

N/A Vane replacement is easy. Simply remove the outboard head assembly, slide out the old vanes, insert the new ones, and reinstall the head. In a matter of minutes, your pump is back in operation. Routine inspection is equally easy. In fact, most maintenance can be done without disconnecting the pump from its piping or drive shaft.

Replaceable Liners Economically Restore Efficiency

N/A Blackmer LGL pumps are equipped with replaceable liners that protect the pump casing and provide the economy of simple replacement, restoring the pump to like-new efficiency. No special tools are required to remove a worn liner and install a new one, and the simple operation can be completed in a few minutes without taking the pump off line.

UL and ISO 9001

N/A All pump (LGL158 is listed for use on LP-gas service only.) and bypass valve models described in this bulletin are listed by Underwriters Laboratories for both LP-gas and anhydrous ammonia service.
