MP1 Multiphase Screw Pump Applications
Crude, Product and CO2 Pipeline, Drilling and Production
Double-Suction Design provides balanced hydraulic loads by channeling incoming flow to the screw inlets at each end of the pump.
External Bearings and AGMA 11 Timing Gears are in separate oil reservoirs to eliminate exposure to the pumped fluid.
Versatile ISO 21049/API 682 Seal Chamber readily accommodates multiple seal types and meets HSE regulations without modification.
Split Bearing Bracket Construction facilitates easy maintenance of individual bearings and mechanical seals.
Modular Non-Welded Casing is available in multiple standard and specialty alloys.
Nozzles integral to the outer casing insulate the inner casing from piping loads, helping to maintain a non-contacting shaft design.

FAQ
What is a twin screw multiphase pump?
A twin screw multiphase pump is a positive displacement pump that can handle liquids, gases, and solids simultaneously. The MP1 Multiphase Screw Pump is specifically designed for extreme GVF (up to 100%) and high-viscosity fluid handling.
What sets the MP1 Multiphase Screw Pump apart from standard screw pumps?
The MP1 features dual suction screws, split bearing bracket construction, external lubrication and non-welded casing, all tailored for high-stress, high-performance applications.
Can the MP1 Multiphase Screw Pump handle solids and slurries?
Yes. It handles up to 70% solids by weight, making it highly suitable for slurry transport and pulp processing applications.
Is the MP1 suitable for vacuum-related processing?
Yes. The MP1 is also used in vacuum-assisted systems, ideal for plants looking for screw vacuum pump solutions.
What sealing options are available?
It supports a wide range of mechanical seals through its ISO 21049 / API 682 compliant seal chamber, allowing flexible adaptation to process requirements.
