MP1Multiphase Twin-Screw Pump

The Flowserve MP1 double-suction, twin-screw, positive displacement pump was specifically engineered to handle the most aggressive challenges of today’s multiphase upstream oil field production while consistently providing high availability. The rugged and versatile MP1 readily accommodates rapid changes in oil well viscosities, water cuts, gas-to-liquid ratios and gas volume fractions (GVF), which vary over the life of the oil field. The pump’s versatility, mainte-nance ease and reliability provide users with life cycle cost economies to optimize oil production.

The Flowserve MP1 is the most robust twin-screw pump in the oil and gas industry. Engineered for multiphase pumping, it features a double-suction, timed twin-screw configuration built in accordance with API 676, latest edition. The design of the MP1 was further refined to provide the highest overall efficiency and lowest operating vibration levels of any multiphase, twin-screw pump.
