Description

Overview

This QBK25/40 diaphragm pump seal kit is the complete wet-end service set for both the QBK25 and the QBK40 air-operated diaphragm pump. The 1″ and 1.5″ pumps share the same kit, so one part number covers two sizes and every body material.

Diaphragms, balls and seats are the parts that wear, and fresh ones restore flow and priming. Keep a kit on the shelf with the pump, or fit it when output drops or liquid appears in the exhaust. See the QBK25 aluminium diaphragm pump and the QBK40 aluminium diaphragm pump, or browse our diaphragm pumps.

Two further Viton seals, four balls and four ball seats

Service kit code S/A-QBK25

Where it works

Plants that run a pump every shift treat a seal kit as a consumable. Fuel depots in Mpumalanga, chemical blenders in Gauteng and packing sheds in the Western Cape all rebuild their transfer pumps on a schedule, and the shared kit keeps the shelf simple when you run both sizes. A split diaphragm shows up as liquid blowing from the exhaust, and early replacement saves the air line and the product.

Rebuild on a clean bench, check the housings for scoring and fit every part in the correct order.

Questions about this product

Will this kit fit my QBK25 or QBK40 pump?

It fits QBK25 and QBK40 pumps in aluminium, polypropylene and stainless steel bodies, because the wear parts are common across the bodies. Check that your pump is a QBK25 or QBK40 model before ordering, or send us a photo of the pump plate and we will confirm it fits.

Is one kit enough for a QBK40 pump as well?

Yes. The same S/A-QBK25 service kit covers both the QBK25 and the QBK40, so you only need one kit per pump rebuild. If you run both sizes, a couple of kits on the shelf cover them. Tell us your pump model if you are unsure and we will confirm.
