Pressure Testing Pumps
We design and manufacture pressure testing pumps 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).
The Pump
For pressure testing we select from the Hammelmann range of high pressure, reciprocating plunger pumps. This range offers performances of up to 700 bar and 500 lpm. They feature a vertical mounting orientation which helps to keep the unit footprint to a minimum. Above all, these pumps are renowned for their reliability and long service intervals.
Pump head material options include 316, Duplex, and Super Duplex (25% Cr) stainless steels to suit the operating environment.
Mounting
Our pressure testing pumps are generally mounted in an ISO 10855-1 certified container. A popular feature is the addition of an integrated control room so that operators are able to perform testing from a safe location. One of the benefits of a container-mounted unit is the inherent noise attenuation and indeed the option for enhanced noise attenuation.
Hazardous Area Pressure Testing Pumps
As with most of our well service pump packages, these pump units are manufactured for hazardous area operation – particularly Zone 1, Zone 2, NORSOK, IECex, CSA, CRN, or rig safe.
