DL45 Replacement Hydraulic Stack (Pump Cartridge)

Price range: R7,680.00 through R57,480.00

Genuine replacement hydraulic stack for AQS DL45 vertical multistage pumps – restores your pump to factory performance. Select your exact pump model (DL45-10-1 to DL45-130-2).

SKU: DL45-STACK Categories: ,

The hydraulic stack is the “heart” of a vertical multistage pump: the complete set of impellers, stage chambers (diffusers) and shaft that builds up the pressure. Over time sand, grit or running dry wears the impellers and the pump loses pressure and flow. Fitting a new stack brings your DL45 pump back to its original performance for much less than the price of a new pump – the motor, base and outer sleeve are re-used.

  • Fits: AQS DL45 range vertical multistage pumps
  • Supplied as a complete cartridge stack for the model you select
  • Mechanical seal is sold separately – we recommend replacing it at the same time (code 95020102, fits DL32, DL45, DL64 & DL90)

How to choose the right stack: read the model on your pump’s nameplate, for example DL45-70-2. The number after the dash tells you how many stages the pump has (e.g. -40 = 4 stages), and the stack must match it exactly – a stack with a different number of stages will not fit the sleeve and will not give the right pressure. Not sure? Send us a photo of the nameplate and we will confirm the part.
