The A-M Vantage Virage pump is now a lot happier! The body was bored out to take a more readily available seal from a well-known 5.3 V12, quality NKE Austria bearings, the impeller was gently warmed to assist in getting the locking screw to line up and find its threads, its turned out nicely with a healthy amount of seal drag.

Warning to all small engineering businesses.
We have just had to confront and eject someone from our premises who came to the door unannounced, dressed in suspiciously clean hi-viz, with a cockandbull story about a broken down road scanner.
They are just trying to acquire high value materials: carbide, brass plate, stainless, anything.
They will get argumentative and noisy, play the victim and try veiled threats.
Don't let them in.
Small black Caddy type van, might have been a 19 plate.

We were very pleased to renew our relationship with Network Rail S&T this summer with the turnkey supply of 50 fence bottle switches (aka chalk fall detection) in cast phosphor bronze from our own patterns.
