PCM Moineau™-PCP mit sehr niedrigem NPSH-Wert

PCM API 676 standard PumpenPROJECT DESCRIPTION

Closed Drains Systems on offshore platforms collect hazardous waste fluids and spillage. The fluids are collected and stored in a drum to prevent contamination of surrounding sea water. The installation containing the hydrocarbon waste has a high vapor pressure has less than 0.5m (1.5 ft) NPSH available. A pump with ultra low NPSH requirement is needed to periodically empty the drum.

FOCUS ON PRODUCT

PCM Moineau™ Progressive Cavity Pumps (PCPs) were configured for horizontal installation, adjacent to the closed drains drum. The low NPSH requirement enabled fluids transfer without cavitation. The pump’s wetted parts were constructed from corrosion resistant alloys and in-house blended elastomers for compatibility with the array of pumped fluids.
