The overall Leistritz design philosophy is to engineer a multiphase pump package suitable for each application, using standard building blocks and without unnecessarily complicating the system. Our ability to package in both North America and Europe allows us to easily adapt to local conditions and utilize local sub-suppliers ensuring our packages are based on familiar and approved components. Once installed, Leistritz Multiphase Pump packages are supported by our worldwide service network.

Pressure Boosting Multiphase Pumps boost production flow line pressure. This enables lower wellhead backpressure, resulting in increased production and total recovery. Leistritz standard units are packaged for operation in remote locations, and safely accommodate 100% gas for extended periods. VFD speed control maintains a constant inlet pressure regardless of the number of producing wells, and prevents low-pressure wells from being shut in.

Gathering Multiphase Pumps improve the economy of remote or marginal fields by eliminating field separation, and transporting untreated well production to centralized process facilities in a single pipeline. This reduction in facilities also means less impact on the environment. It eliminates flaring of associated gas, and uses small-footprint equipment in place of large, satellite process facilities.

Sub-sea Multiphase Pumps in sub-sea booster applications allow economic production of remote tieback wells, boost production of aging wells with declining reservoir pressure, and facilitate flow assurance by drawing down flow-line pressure. Depending on its location (wellhead, riser base, or in-between), a sub-sea booster pump provides an economical and predictable tool to increase total recovery, regardless of changing GOR or water cut.

Flow Assurance Multiphase Pumps are excellent tools to deal with flow assurance issues. The mitigation of hydrates by drawing down the line pressure below the hydrate formation point prevents blockage and saves inhibitor costs. Oil/water emulsions can be pumped with minimum shear and agitation facilitating emulsion breakup. Surging and slugging, which can be problems in offshore risers and cause upsets in the production separator, can be avoided by using a multiphase pump on the receiving end.
