ARO 637391-GG Nitrile Fluid Section Service Kit
Service kit for 1 1/2" ARO PD15P fluid sections; diaphragm and balls are both Nitrile.
Nitrile service kit for the 1 1/2" fluid section of ARO PD15P-YPS-PGG and PD15P-FPS-PGG pumps, with diaphragm, balls, gasket, U-cup and O-ring.
ARO 637391-GG rebuilds the fluid section of a 1 1/2" ARO double diaphragm pump using Nitrile elastomers. The GG suffix marks Nitrile for both the diaphragm and the balls, and the same letters close out the model numbers of the two PD15P pumps listed below.
According to the product notes, the kit includes a grease package, gasket, U-cup, O-ring, ball and diaphragm. That lets you replace the flexing and sealing parts in one service rather than ordering them one by one. The pump's operator's manual shows where each piece sits.
Signs the Fluid Section Needs Service
- Pumped liquid is leaking from the muffler or air outlet.
- Seepage appears at fluid section joints where gaskets and O-rings seal.
- The pump short-strokes or delivers less fluid per cycle than before.
Compatible PD15P Pump Models
Both listed models share the PGG fluid end code; match yours on the nameplate before you buy.
