Mustang® Liquid Sample Pump

The Mustang® Liquid Sample Pump (MLSP) is a patent pending system offering accurate and repeatable process control measurement for Natural Gas Liquid applications. Sample pressure is increased to meet analyzer requirements and complete the transition to liquid phase in dense phase tower bottom streams.

The MLSP allows for the use of a liquid return to process speed loop when sample point pressures are equal to or less than return point pressures. A completely pneumatic system eliminates the need for electrical classifications removing timely design processes and restrictions for installation. The MLSP becomes an integral component of a complete sampling system for problematic processes such as cryogenic tower bottoms.
