How to use this parts list
- Qty per pump is the number of that part fitted in one pump – order that quantity for a full set (e.g. all gland packing rings), or fewer for a partial repair.
- Order by part code. Where a part is offered in more than one material (cast iron, stainless steel, EN8, tool steel, nitrile, Viton, Hypalon, natural rubber), choose the material that matches your pump build and the liquid pumped.
- Rotor and stator must be matched: a stainless or hard-chrome-plated rotor runs in the same stator sizes, but the stator rubber (nitrile, natural, Viton, Hypalon) is chosen for the liquid temperature and chemistry.
- Parts marked Price on request are stocked or ordered to demand – send us the code for a price and lead time.
