PG-MAPS PilotUnique Pump Solution for Topside and Subsea Applications – as built and tested
3
• Subsea Tophole drilling, Mud & Drillcuttings transportation
• Flooding/ flushing of pipelines topside or subsea
• Subsea injection of Water/ Chemicals/ MEG/ Methanol
• Liquid boosting/ pumping
Hose Diaphragm PumpApplications
• Four off - hose diaphragm pump heads
• 2 off - Electrical linear actuators in twin drive configuration
• Pump technology, well known slurry , waste water, industrial mining and sewage,
• Well proven design www.Feluwa.de
Hose Diaphragm PumpConfiguration
Technology of pumps and drive
• Gain all advantages of the Hose Diaphragm pump technology
• Combined with a light weight and powerful Magnetic (PMM) linear drive
• All Electric Pumping sequence 4 pumpheads
Top view configuration
Hose Diaphragm PumpAdvantages-1
• Zero NPSH - • No topside VSD – only subsea control POD• No topside lube-oil unit• No cooling arrangement is required• No pulsation
– when 4 pump-heads are configured with two actuators
• No dynamic seals or product lubricated seals• No rotational pump parts in the process = less
wear• Built in redundancy
– pump with reduced capacity with one actuator and two pump heads.
Hose Diaphragm PumpAdvantages-2
• Tolerant to sand and particles – <20mm in this configuration
• Zero leakage to the environment – as the pump and drive is hermetically sealed.
• Safety – Hydraulic fluid and pumped fluid separated with a double
hose diaphragm.
• Subsea Motor Control POD located close to pump – Retrievable and packed in a canister.
• Standard control signals/ digital signals connected to client control POD
• AC or DC power supply/ transmission
