Liquid Terminals: Frequently Asked Questions

Back to top

What models of Blackmer pumps are available for use in liquid terminals?
Blackmer has developed multiple lines of pumps that are effective in bulk liquid transfer, including ProVane Motor Speed Vane Pumps, ML/HXL Series Sliding Vane Pumps, GX/X Series Sliding Vane Pumps, NP/SNP Series Sliding Vane Pumps, TX(S)D Series Sliding Vane Pumps and System One Centrifugal Pumps.

Why are Blackmer sliding vane pumps more energy-efficient than other pumping technologies?
The unique design of Blackmer’s sliding vane pumps offer a high level of energy savings thanks to their volumetric efficiency, consistent performance over time and high mechanical efficiency. In fact, sliding vane pumps are up to 24% more efficient than gear pumps on thin to moderately viscous fluids.

What benefits do Sliding Vane Pumps provide that other types of pumps don’t?
All Blackmer sliding vane pump lines are designed to conquer the most problematic challenges in the transfer of liquids of various viscosities. The unique self-adjusting vanes eliminate efficiency-robbing “slip,” helping the pump to maintain near-original volumetric output and consistency even after significant service. Other design benefits include seals and bearings designed for maximum life; a wide range of flow capacities; superior priming and suction capabilities that make them ideal for line stripping; complete evacuation of heels and superior lift; and easy maintenance that allows vanes to be replaced without removing the pump from the piping system. In addition, their exceptional suction/lift capabilities make sliding vane pumps ideal for top unloading of vessels.

What type of preventative maintenance has to be performed on Sliding Vane Pumps?
Besides normal plant lubrication schedules, simply replacing the vanes periodically makes Blackmer sliding vane pumps a very reliable asset. To replace the vanes, simply remove the vane cover and pull out the worn vanes. Then install new vanes and replace the vane cover.

What are the materials of construction for the various Blackmer pumps?
ProVane Motor Speed Vane Pumps are available in ductile iron and stainless steel. System One Centrifugal Pumps are available in ductile iron, stainless steel, alloy 20 and Hastalloys. ML/HXL Series Pumps are available in ductile iron. GX/X Series Pumps are available in cast iron and ductile iron. SNP/NP Sliding Vane Pumps are available in cast iron and stainless steel, and TX(S)D Series Pumps are available in cast iron.

What types of Blackmer pumps would be recommended for blending at the terminal?
Their excellent volumetric efficiencies make Blackmer’s GX, ML/HXL, Provane Motor Speed and TX(S)D Series Sliding Vane Pumps ideal for blending operations.

Which Blackmer pumps perform best in caustic and acidic applications transfer?
Due to their stainless steel construction, metallized carbon sleeve bearings and non-metallic vanes, Blackmer SNP Series Sliding Vane Pumps work best in handling caustic fluids. They also have a non-galling feature that reduces maintenance costs and operational difficulties. The Blackmer ProVane Motor Speed Vane Pump and System One Centrifugal Pumps are also preferred for these difficult applications.

Does Blackmer offer small energy-efficient pumps?
Blackmer’s highly efficient ProVane® Motor Speed Pump Series has been designed with four port sizes ranging from 3/4 to 2 inches and flow rates from 2 to 100 GPM.

What smaller footprint pumps does Blackmer have for applications where space is limited?
The small footprint of the ProVane Motor Speed Pump Series make it ideal for limited-space applications.

Are the elastomers and mechanical seals on Blackmer pumps compatible with biofuels?
Blackmer pumps have been configured with elastomers and mechanical seals, compatible with the handling of biofuels.

Does Blackmer make seal-less pumps?
Blackmer makes the seal-less SMVP pump.
