Frequently Asked Questions
Wet‑cup pumps have larger bore size and volume; the nut size is scaled to properly retain the larger packing area and higher fluid loads.
No — using a smaller nut can cause insufficient packing compression, leading to leaks and excessive wear.
Signs include fluid seepage around the nut, packing shifting, decreased pressure or irregular pump cycles.
