If you are looking for efficient methods of transferring liquids in the production of detergents and household cleaners, then AxFlow believes that it has the best solution with its Blackmer sliding vane pumps. The range of Blackmer pumps available from AxFlow processing duty comprises the SNP Series, the SMVP Series and the ProVane®, and each has a role to play throughout the production cycle.
The SNP pump series has the widest range of applications and can be used throughout the household cleaner manufacturing process. They offer the highest levels of top to bottom unloading of product components as a result of their exceptional vacuum, line stripping and tank-cleaning capabilities. These capabilities are further enhanced by the SNP pump’s ability to handle product viscosities in excess of 4,250cP. Also, product containment is not an issue as the pump comes with a choice of sealing options.
Pre-mixing and mixer/blending processes are addressed by the SMVP seal-less mag-drive sliding vane pump series. The magnetically coupled design of this pump delivers zero shaft leakage, thereby preventing costly product loss when handling difficult to seal ingredients. The SMVP also offers exceptional flow-rates ranging from 15 to 813 litres/min at temperatures between -40ºC and 96ºC.
Rounding up the Blackmer range for this industry sector is the ProVane motor speed vane pump which has been designed for the transfer of products with direct motor coupling at speeds up to 3,600rpm and flow rates up to 795 litres/min. ProVane pumps are capable of providing continuous operation while maintaining optimum volumetric efficiency. This pump series also has great self-cleaning and line stripping capabilities for cleaning tanks, lines and pump chambers. As the pumps only contain one mechanical seal and has hydrodynamic journal bearings, the risk of leaks and product loss is significantly reduced, while their high mechanical efficiency provides lower operating costs.
The Blackmer vane pump contains a number of vanes that are free to slide into and out of slots in the pump rotor. When the drive mechanism starts the rotor, centrifugal force, push rods and/or pressurised fluid causes the vanes to move outward in their slots and bear against the inner bore of the pump casing forming pumping chambers. As the rotor revolves, fluid flows into the areas between the vanes when they pass the suction port. This fluid is transported around the pump casing until it reaches the discharge port. At this stage, the fluid is squeezed out of the discharge port. The technology is appropriate for handling shear-sensitive products where energy efficiency and minimal product loss are essential factors in the production process.
