Products are manufactured under a quality system, previously: ISO 9001:1994 [DNV Nbr. 95-LON-QA-458 (15105)]. And jointly: ASME "U" Cert 29,289 5 Nov '96 through 5 Nov '99, and through 5 Nov '02 [Kemper/BVQI - QSC 97028/50591 1997/98]. Now via LDi UK - RSA to ISO 9001:2000 valid through 6 October 2007. When you require products assembled under the auspices of that third party they will come via that UK source.

Modular vessel construction enables shorter lead times and lower cost.

Understanding Pipeline Surge / Shock Alleviators
Shock alleviators and shock accumulators do not alleviate shock, nor do surge alleviators and surge accumulators alleviate surge. SurgeGuard, JumboFlex, and Floatolator all work in the same way. They provide a soft place, so that the pump does not have to instantly accelerate all the liquid in the pipe system when it starts. Similarly, they provide a place into which flow can continue, for a time, against increasing resistance, when a a valve has been slammed. In both cases, because time has been increased, peak pressure generation is decreased. In short, they all prevent the peak pressure from being generated.
