Pump Part Number Matrix

Check your pump's identification plate (ID) for the 6-digit part number.
Use the following matrix to define the construction of your pump, based
on the six digits. For example, Part No. W 1 5 A A S represents a wet cup
pump (W), 15 to 1 ratio (15), 25 cc lower (A), 3 UHMWPE/2 PTFE pack-
ings with chromex rod coating, no data monitoring, low noise exhaust
(A), and stainless steel construction (S).
