We design and manufacture pump units for both pipeline fill/flooding and high pressure testing. Through our bespoke design capabilities, these units will meet your application and operating specifications.

For pipeline fill/flood we generally select high pressure, high flow, multistage, centrifugal pump packages. Built around either a ring section or horizontal split case API 610 pump, these units are designed for pressures of 30 bar (435 psi) to 250 bar (3,600 psi) with flows of 300m³/hr (1,320 gpm) to 600m³/hr (2,640 gpm).

For pressure testing we select from the Hammelmann range of high pressure, reciprocating triplex plunger pumps. This range offers performances of up to 700 bar and 500 lpm. These pumps are renowned for their reliability and long service intervals. They feature a vertical mounting orientation which helps to keep the unit footprint to a minimum.

Pump head material options include 316, Duplex, and Super Duplex (25% Cr) stainless steels to suit the operating environment.

As with all our well service pump packages, these pump units are manufactured for Zone 1, Zone 2, NORSOK, IECex, CSA, CRN, rig safe, or safe area applications and benefit from a comprehensive range of control options.
