Multi-phase pumps are boost and delivery equipment, commonly used in oilfields that have untreated streams. In order to satisfy multi-phase delivery of oil, gas and water, containing small particulates, FPDS multi-phase pumps adopt a unique screw profile and design along with a special pump casing chamber to achieve boosting for gas in mixture and heat distribution.
In order to meet a variety of adversery operating conditions in the field, FPDS multi-phase pumps use specially selected materials, hardening treatment and specialty seals. To allow our customers simple, convenient and quick installation FPDS can provide a multi-phase skid system that includes filter, valve, circulation system, mixer, connecting pipeline and control equipment.
Our advantages：
• Stable single piece rotor；
The heavy-duty pump features a reinforced shaft structure, which minimizes shaft deflection, ensures more stable pump operation, and greatly reduces the risk of shaft breakage.
• Compared to competitor B, the pump has a longer service life；
The FF-Positive multiphase pump employs external recirculation, reducing wear on the rotors and liners, and can extend the pump's service life by more than twice.
• Compared to competitor B, the pump has a longer service life；
The mechanical seal is located in the low-pressure chamber, with low pressing force and low heat generation. When a step flow causes the pump to heat up rapidly, the low-temperature clean liquid from the external recirculation tank can first cool the mechanical seal, ensuring its longevity.
• Low pump temperature rise；
When the conveying section experiences plugging, gas compression generates a large amount of heat, causing the pump to heat upr apidly. An external cooling return tank increases the cooling surface area, doubling the overall heat dissipation.
