Such critical applications encompass high flow, high differential pressure and high suction pressure in cryogenic duties. The SPX Processing Equipment’s Novaplex pump was developed for such duties and conditions and is now being specified for new installations and as a replacement for existing units.
The Novaplex uses hydraulically actuated double diaphragms and the absence of sealing gaps removes the possibility of the pumped liquid leaking and thereby creating a safety problem. In addition, wear on the plungers is minimised, thereby excluding any chance of wear induced leakage. The modular phased pump heads are a significant contributor in assuring a smooth product flow.
The pumps have an integral lubrication system that does not necessitate external control or cooling.
