Brain Airloader Pumps are designed for handling
heavily solids laden slurries and sludges normally
considered impossible with conventional pumps.

The Airloader PD4x4(500) is a portable, compressed air powered unit, totally intrinsically safe and capable of passing solids up to 80mm in lump size.

Unlike conventional pumps, which rely on vacuum displacement, the Airloader PD4x4(500) generates a high velocity suction airflow (25cu m min /900cfm) combined with a powerful vacuum (-0.88 Bar/26”Hg) resulting in aggressive suction performance. 

This enables the thickest and most viscous of materials to be suction loaded with horizontal distances in excess of 100m and vertical suction lifts in excess of 35m being achievable.

Material is discharged from the pumping vessel by compressed air with transport distances up to 1000m horizontally and heads of up to 60m easily achieved even with high solids content materials.

PERFORMANCE – With no moving parts in contact with the material, large lump solids inclusions, waxy, fibrous and abrasive materials may be handled. Performance is dependant upon the type of material being handled, the suction lift and the discharge run. Flowable slurries are recovered at a higher rate than viscous sludges. Typical production rate is 20m3/hr.

APPLICATIONS – Safe for hazardous area operation and removal of material from confined locations.
Typical uses include: Tank, sump & FPSO cleaning, face slurry removal, pump lodge de-silting, winding shaft sump cleaning, sewer digester cleaning, culvert cleaning and pond de-silting.

OPERATION – Automatically controlled by pneumatic timers pre-set to achieve an optimum fill and discharge cycle with manual override capability.
