Industries We Supply

The same frames turn up in very different machines. These are the sectors we supply most often, and what matters in each.

Knowledge Centre

Reference material written for people who identify pump parts for a living, not for search engines.

How an Order Runs

  1. Send the model code

    The code stamped on the nameplate, or a photograph of it if the stamping is worn.

  2. We confirm the frame

    An engineer checks frame, size, rotation and ports against what we machine, and says so plainly if it is outside our range.

  3. Written quotation

    Price, lead time and shipping date in one document, with the frame you are buying stated explicitly.

  4. Machined, tested, shipped

    Parts are lapped and matched as sets, bench checked where applicable, then packed for export.

Frequently Asked Questions

Can you identify a pump if the nameplate is unreadable?

Usually yes. Send photographs of the pump from the port side and the mounting flange, and of the valve plate if it is already apart. Those three views identify most frames.

Do you supply single parts or only complete sets?

Both. Rotary groups and cartridge kits are supplied as matched sets because the clearances have to be set together. Cylinder blocks, valve plates, piston rings and similar wear parts are also sold individually.

Will the parts fit without modifying the machine?

That is the design intent. Mounting, shaft, ports, rotation and control have to match for a replacement to be a genuine drop in, and we check all five against your code before quoting.

Can you make parts for pumps that are out of production?

Obsolete and hard to find parts are a large part of what we do. If we can measure a sample or work from a drawing, we can usually machine it. Where we cannot, we say so rather than substituting something similar.
