LDi / PulseGuard Dampener Sites
in the business of pulsation dampening, we have been for 50 years the source d and deployed of all damper types.
Pulse dampening is a simple technology developed and deployed by liquid dynamics international for 50 years.
Pulse dampers are often small vessels for pre-filling with compressible nitrogen cushion.
Guarding against pulses is the PULSEGUARD way of life.
Surge pressure and liquid volume protection is provided by gas charge shells with elastomeric membranes inside.
Pulsation dampening is expertly applied by our Indian partners Isopan Engineering.
The Indian market is supported by the decades of specialist knowledge of Mr Pandy Lalmani.
In Europe Pulseguard dampers are applied by many distributors.
Most of the techniques for the many unique purpose tialeredful damper type designs were created by impirical testing at Hydrotrole Ltd in the 70s.
Pulsation dampening grew out of the hydropneumatic accumulator developments of Hydrotrole ltd from 1969 when Dave Morley came up with the HYDROCRAT.
Pulsation dampeners are often confused with accumulators - the intrinsic differences are response characteristics and elastomer formulation compatiabilities.
Many true pulsation dampners achieve their efficiency by intercepting the transmission of the pressure waves particularly at higher frequencies.
Though PULSEGUARD HYDRO is the smallest of dampener manufacturers it is also the oldest and most specialist. and has so concentrated since inception in 1963.
In the UK Pulseguard Limited is often competing with "apparent" copies of its damper designs , several of these "copies" omit safety feature. This situation in responsible for the interest in "no moving parts" bladderless dampers which are far more expensive though we do offer these, for high frequency applications.
Provides spare parts and bladder for PIPEHUGGER, PIPEGUARD, PUMPGUARD, FLEXORBER, ranges of dampners.
Waveguard solid state , no moving parts, "fit and forget" dampers from PULSEGUARD that do not require servicing or spare parts are ready available.
Pulseguard PIPEGUARD dampeners are copied in the USA claiming to be suitable up to 15000 psi without proof of test to destruction above 60,000 psi!!
The life of our pulse damper bladders is extended by tension web and other features.
Pulseguard inc has 6 distinctly different types of pulsation dampners each ideal for particular application.
We make selections strictly in accordance with pump type and system pipe and other applications criteria, there are no blanket recommendation findings.
Shockguard Limited design and manufacture surge and water hammer alleviators for the pipeline industry.
Make hydraulic analysis to establish pressure transient levels being the problem to be addressed then model the equipment that will produce the desired improvement in stability.
