Super Duplex. Super reliability.Chemical liquid pumps just got smaller, lighter and tougherThe Danfoss range of API pumps combines compact axial piston pump technology with precision production in Duplex and Super Duplex. Pump reliability for the oil and gas industry has never been this good.

MAKING MODERN LIVING POSSIBLE

Danfoss Axial pumps

Chemical liquid pumps that punch way above their weight

The Danfoss Group has more than 40 years of experience develop-ing and producing axial piston pumps. Today Danfoss is among the three largest manufactures world-wide of this pump technology.

We listened to the needs of industries that require reliable but lightweight pumps in extreme environments. Then we adapted the axial piston technology used in heavy-duty hydraulic a pplications to ultra-compact pumps – all made in some of the most corrosion-resistant materials available.

With Duplex and Super Duplex inside and out and our patented production technology, we produce chemical liquid pumps that keep process platforms in business.

Maximum reliability. Minimum footprint and maintenance. More than 20 patents. All in one pump.

Danfoss Axial pumps

Traditional Plunger pumps

Axial piston technology makes it possible.Duplex and Super Duplex make it lastTraditional diaphragm or plunger pumps are built with few but relatively large chambers and pistons, and rely on crankshafts to transfer power and check valves to control the flow.

DanfossCLPpumpsuseaxialpistontechnology to deliver powerful perfor-mance.Crankshaftsarenotused,mul-tiple pistons run against a swash plate and integrated port and valve plates control flow.

BecauseDanfossCLPpumpspacksomuch power into a compact design, it is now cost-effective to build the entire pump – inside and out – from Super Duplex and carbon-reinforced PEEK.

Traditional suction/ pressure check valves are replaced by a simple port and valve plate – further reduc-ing complexity and maintenance worries.

5-9 pistons deliver extremely low pulsa-tion rates eliminating the use of pulsation dampeners.

Traditional crankshafts are replaced by a sim-ple fixed swash plate. No need for oil lubri-cation:thepumpedmedium provides all necessary lubrication.

Power has never been this compact.Maintenance has never been this simple.

Fewer service routinesDanfossCLPpumpsarenotonlyeasier to find room for. They also require much less service to keep them running. Breakthrough design and manufacturing technology mean that the pumped fluid provides all the lubrication that is necessary, and check-ing and changing oil, seals, belts and pulleys are all things of the past.

Longer meantime between servicesWhile traditional pumps have service schedules that include monthly, weekly and even daily maintenance tasks, DanfossCLPpumpsneedtheirfirst

Corrosion resistantAllwettedpartsofDanfossCLPpumpsare produced in Duplex or Super Duplex. We have also used the latest polymer and surface treatment tech-nologies to provide the very best resistance to corrosive and low viscosity fluids.

PREVENTATIVE MAINTENANCE CHECKLIST API AND NORSOK

Both the metering pump, CLP 675, and multipurpose pump, CLP 674, are designed according to API standards.

Pumps can also be delivered according to NORSOK M-630 and M-650.

Lightweight, small footprintDanfossCLPpumpsarebasedontheaxial piston principle to make them as compact as possible. This means they are much easier to transport and handle than traditional pumps – and far more simple to configure in systems where space is at a premium.

Proven technology at work in some of the world’s toughest environments

The challenge: Upgrading the produced water system Dong Energy took over the Siri oil field in 2002 and has since made it one of the most cost-effective production platforms in the North Sea.Upgradingtheproducedwatersystemaspartofanenvi-ronmental improvement program required new pumps to inject biocides,scaleinhibitorsandoxygenscavengers.Inadditiontopump reliability, Dong Energy wanted to save space and weight – and electricity.

Vendor flexibility was also crucial in case spare parts or replacement pumps were needed.

The solution: Three sets of two pumpsDong Energy selected a solution that consisted of three sets of two Danfoss pumps to provide complete redundancy. Despite the extra pumps, the new system was considerably smaller and lighter than the previous one.

The challenge: More condensate through existing infrastructure MaerskOilandGaswasthefirstcompanytoestablishacross-borderinfrastructure agreement in the North Sea, sending condensate fromtheNorwegianTrymfieldforprocessingatMaersk’sHaraldplatform in Danish waters.

“Reliability was a given, but we were especially looking for high-capacity pumps that don’t take up much room. Danfoss CLP pumps deliver on both counts. We are often pioneers in new technology, so the idea of trying some - thing new is not foreign to us.“

Finn Schweitz ChristensenAssistantPurchasingManager

“We once thought we had a problem with one of the pumps, and Danfoss flew a replacement to the rig in less than 24 hours. It turned out that there was actually nothing wrong with the pump. Since we depend on 100% uptime, confidence in our suppliers is a must.“

With average costs on offshore plat-forms running up to $35,000 per m2 and$70,000pertonne,it’snowonderthat space is at a premium. That’s why our latest innovation packs more high-pressure power per cubic inch than everbefore.Andtosaveyouinstalla-tion costs as well as space and weight, we’ve also made it as close to plug and play as it can be.
