Pump Platform & Replacement Guide
Single-Stage Overhung Process Pumps
ANSI B73.1 and equivalent frames — casings, bearing housings, seal glands and impellers.
Jet & Domestic Booster Pumps
Jet pump casings, square casings, long- and short-head casings and pump covers.
Between-Bearing & Split-Case Pumps
Casings, covers and double-suction impellers for larger water and transfer duty.
Vertical Turbine & Sump Pumps
Bowl and column castings, brackets and bearing housings for intake and dewatering.
Engineers Search for the Nameplate, Not for “Custom Impeller”
A maintenance engineer standing in front of a stripped pump searches for the model on the nameplate. One page per pump family and one per model is how we keep the interface dimensions for each frame in one place instead of re-measuring every time.
Tell us the frame and we will confirm which interface dimensions we already hold and which ones we need measured off your part.

Frequently Asked Questions
What is the minimum order quantity for replacement wet-end parts?
100 pieces. Twin vertical-line moulding is a batch process — it is what keeps the hundredth casting the same as the first, and it is why we quote in batches.
Can you supply parts for discontinued frames?
Yes — discontinued frames are the common case. With no current drawing available, we work from your worn part and confirm the interfaces against it.
Do you supply bare castings or finished parts?
Either. Bare castings suit customers with their own machine shop; most orders ship fully machined, balanced and inspected.
How do you guarantee the part will fit?
By measuring the interfaces on your part rather than trusting a catalogue number, and by listing on the quotation every dimension we had to assume.
