Progressing Cavity Pumps for Offshore FPSO Platforms and Onshore Oil & Gas Processing
Progressing cavity positive-displacement pumps
Torqueflow Sydex’s range of cavity positive-displacement pumps is extensive and includes the original Moineau pump design with the stator bonded into a steel tube. Pumps can be supplied in accordance to API 676 specifications with seals to API 682 where specified.
Progressing cavity pumps are widely used in the offshore oil and gas industry. Applications include:
- Offshore oil and gas drilling platforms, fixed and floating (FPSOs)
- Flare knock-out drums
- Low NPSH applications (high suction lift applications)
- Crude oil processing
- Drilling mud
- Waste oil
- Oil-water separation
Horizontal progressing cavity pumps
The ‘K’ range of horizontal progressing cavity pumps is the core offering from Torqueflow-Sydex. The range is available in a wide range of materials, including cast iron, and stainless steel 304 and 316 through to duplex steel (SAF 2205), to suit highly corrosive and difficult applications such as high salinity laden liquids including produced water.
Double seal systems to API682 with flushing systems to plan 52 or 53A as required are available, particularly where there are high levels of H2S present.
Pumps can be supplied with full ATEX hazardous zone certification, or NEMA classification
Vertical progressing cavity pumps
The highly versatile vertical ‘E’ range pumps are also known as barrel emptying, vertical sump or semi-submersible pumps. Vertical pumps are suitable for numerous applications within the oil and gas, and chemical industries where high suction lifts (low NPSHa) are an issue. The pumps can be directly mounted inside a tank, keeping the motor safe from any potentially hazardous and/or corrosive environments.
The ‘E’ range of pumps is available in a wide range of materials, including cast iron, and stainless steel 304 and 316 through to duplex steel (SAF 2205), to suit highly corrosive and difficult applications such as high salinity laden liquids. Other materials including plastic are available upon request.
