Why are Blackmer sliding vane and eccentric disc pumps more energy-efficient than other pumping technologies?
The unique design of Blackmer’s sliding vane and eccentric disc 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. Eccentric disc pumps are up to 30% more efficient than lobe pumps on thin 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.

Which Blackmer pumps are best for the saponification batch process?
The full gamut of Blackmer pumps can be used in the saponification process. Sliding vane pumps can be used in the loading and unloading of bulk products; washing, mixing and fitting stages; drying; and the injection of perfumes and additives. Centrifugal pumps perform loading and unloading functions, mixing and the introduction of brines and acids to the process. Eccentric disc pumps are used in loading and unloading; mixing, washing, fitting and separation process; drying; and additive addition. Peristaltic pumps are used in the initial filtering process and to handle wastewater applications.

Which Blackmer pumps handle surfactants?
The C-Series Eccentric Disc Pump is ideal for moving all types of surfactants due to its seal-less design, which eliminates leaks and product loss. The seal-less design of the SMVP mag-drive sliding vane pump also helps to eliminate leaks and product loss when handling hard-to-seal anionic, cationic and nonionic surfactants.

What is the viscosity range handled by Blackmer sliding vane and eccentric disc pumps?
Blackmer sliding vane pumps are capable of handling viscosities in excess of 75,000 ssu (16,500 cS) depending on the Model and Series of pump under consideration. C-Series eccentric disc pumps are designed to handle viscosities up to 46,000 ssu (10,000 cS). Please consult your local representative or Blackmer applications engineer with the requirements of your specific application.

Which pump is best for the high-volume unloading of materials during bulk transfer?
Blackmer sliding vane pumps are ideal for high-efficiency offloading of raw materials from rail, transports and storage tanks. The sliding vane design offers self-priming capabilities, superior sealing, sustained high-level performance, energy efficiency, trouble-free operation, heel clearing and line stripping, and low maintenance costs. System One® centrifugal pumps offer reliability and high performance in the unloading of raw materials from barges and rail cars.

Does Blackmer have pumps for handling shear-sensitive liquids?
All Blackmer sliding vane, eccentric disc and Abaque peristaltic (hose) pumps are made to handle shear-sensitive liquids.
Go to Top of Page

Can Blackmer pumps maintain a constant flow rate at various pressures and viscosities?
C-Series pumps are able to maintain a constant flow rate thanks to eccentric disc technology that employs an oscillating disc that produces the pumping performance of a positive displacement pump while creating a constant flow that is independent to both pressure and viscosity. All Blackmer sliding vane pump lines are designed to conquer the most problematic challenges in the transfer of liquids of various viscosities, creating a constant flow that is independent of pressure. Sliding vane pumps maintain near-original volumetric output and consistency even after significant service.

Does Blackmer make a pump that has the ability to pass solids?
Depending on the solid size and type, Blackmer has pumps to handle these applications. C-Series eccentric disc pumps have the capability to pass solids up to 3 mm. For larger and/or more concentrated solids, the construction and operating principles of Blackmer peristaltic (hose) pumps make them ideal for moving solids in many soap and detergent applications. The System One® Vortex Pump is designed specifically for solids handling.
