Perforated Plate Drum Pumps AXFP4

In industrial lubricant delivery using high-performance pumps, the full utilization of the medium is a decisive economic factor. The perforated plate for the AXFP4 drum pump series is a specific system component placed at the bottom of the lubricant container. Its primary task is to stabilize the flow conditions in the pump's suction area and to significantly reduce the residual amount of medium remaining in the drum.

When processing high-viscosity greases (up to NLGI class 3), delivery pumps tend to create a crater in the center of the container. As soon as the pump sucks in air, the delivery flow is interrupted, even though considerable amounts of lubricant remain on the walls and bottom of the drum. The perforated plate counteracts this effect by distributing the suction resistance across the entire bottom surface and directing the medium evenly towards the pump suction tube.
 

Product Specification

Manufactured from robust, galvanized sheet steel, precisely dimensioned for the container sizes of the AXFP4 series. The specific hole matrix is aerodynamically designed to ensure a continuous flow to the suction tube, even with high viscosity. The massive construction prevents bending under the high suction vacuum of the drum pump. The perforated plate is designed to support the centering of the pump while simultaneously acting as mechanical protection against the suction of coarse foreign particles from the bottom of the container.

• Precision Fit: 
  The geometry is exactly matched to the inner diameter of the standard drums for which the AXFP4 series was designed.
• Flow-Optimized Geometry: 
  The arrangement and size of the perforations minimize pressure loss in the suction area, ensuring that the pump's delivery performance remains constant.
• Robust Material Quality: 
  A corrosion-resistant surface treatment ensures resistance to chemical additives in lubricants and moisture in the production environment.
• Easy Integration: 
  The perforated plate can be inserted into the container without additional assembly tools and is optimized for use in combination with ABNOX follower plates.

The use of the perforated plate for the AXFP4 drum pump ensures an uninterrupted media supply to the dispensing system. By preventing premature air pockets in the suction tube, cavitation damage to the pump mechanism is avoided, and the repeatability of dispensing cycles is stabilized. The reduction of the residual amount in the container leads to a direct decrease in material costs and reduces the disposal effort for non-emptied containers. Consequently, the perforated plate constitutes an indispensable component for the efficient operation of the tribological chain.
