Sundyne pump protection system receives safety certification

Colorado, US-based centrifugal sealless magnetic drive pump designer Sundyne’s VapourView pump protection system has been cUL, ATEX, and IECEx approved.

VapourView monitors gas inside the process fluid as it passes through a Sundyne sealless magnetic drive pump.

When the probe detects the presence of gas levels – even as low as 1% per volume – a warning signal is sent to the process operator.

This instant feedback helps prevent harm to the pump from occurring by providing early warning of incorrect priming, venting, cavitation, or entrained process gas, which can result in pump damage or even failure.

Power and vibration monitors only alert the operator to the symptoms of gas in the process liquid and in many instances the pump may already be damaged when these monitors are triggered.

By measuring the process fluid condition in real-time with an ultrasonic probe, the VapourView provides feedback instantaneously, ensuring that the pump is working reliably and without risk of damage.

Field installation experience shows that a Sundyne sealless magnetic drive pump fitted with the VapourView system is 50% more reliable compared to other pumps utilised in the same processes, the company reports.

Key features of the VapourView include a non-invasive detection sensor, flameproof electronics, on-board data recording, and a local visual display, as well as a wide temperature operating range of -40-180°C.

The VapourView's 4-20mA output signal is compatible with standard digital control systems and complies with cUL, ATEX, and IECEx standards.

The VapourView system is available as an optional accessory for Sundyne API 685 sealless magnetic drive pumps, including the LMV-801S and HMD/Kontro GSP models, or as a retrofit kit for pumps already in operation.
